The number of minutes that you walk directly from the parking lot to the house will be 12.73 minutes.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The house is located 1480 ft down a paved path that parallels the beach, which is 740 ft wide. Along the path, you can walk 330 ft/min, but on the beach, you can only walk 130 ft/min.
The distance between the house and the parking is given as,
d² = 740² + 1480²
d² = 547,600 + 2,190,400
d² = 2,738,000
d = 1,654.69 feet
Then the time taken is given as,
T = 1,654.69 / 130
T = 12.73 minutes
The number of minutes that you walk directly from the parking lot to the house will be 12.73 minutes.

What is meant by rectangular?A rectangle is a closed 2-D shape with four sides, four corners, and four right angles (90°). The opposing sides of a rectangle are equal and parallel. A rectangle is a type of quadrilateral with four 90-degree-distance vertices and parallel sides that are equal to one another.It is also referred to as an equiangular quadrilateral because of this. A rectangle can also be referred to as a parallelogram since its opposing sides are equal and parallel.A rectangle is a quadrilateral with four equal, right-angled angles. In addition to having all equal angles, a square also has all equal sides. So, a specific example of a square is a rectangle.The following formula determines a rectangular prism's volume:
V = l × b × h
To achieve, we substitute the dimensions.
V = 6 × 3 × 12 in^3
The rectangular pyramid's volume is,
V = 1/3 × 6 × 12 × x in^3
Comparing the two volumes results in,
1/3 × 6 × 12 × x = 6 × 3 × 12

What is 4 2 1 rule ?
The 4-2-1 rule is a guideline used to help determine the amount of water an individual needs to drink each day.
The rule states that an individual should drink 4 liters of water for every 50 pounds of body weight, 2 liters of water for every 50 pounds of body weight if they are exercising, and 1 liter of water for every 50 pounds of body weight if they are in a hot or dry environment.
To calculate how much water you need to drink using the 4-2-1 rule, simply follow these steps:
1. Determine your body weight in pounds.
2. Divide your body weight by 50 to get the number of 50-pound increments in your weight.
3. Multiply the number of 50-pound increments by 4 to get the amount of water you need to drink if you are not exercising or in a hot or dry environment.
4. Multiply the number of 50-pound increments by 2 to get the amount of water you need to drink if you are exercising.
5. Multiply the number of 50-pound increments by 1 to get the amount of water you need to drink if you are in a hot or dry environment.
6. Add the amounts from steps 3, 4, and 5 together to get the total amount of water you need to drink each day.
For example, if you weigh 150 pounds, you would need to drink 4 liters of water for every 50 pounds of body weight (150 / 50 = 3), 2 liters of water for every 50 pounds of body weight if you are exercising (3 x 2 = 6), and 1 liter of water for every 50 pounds of body weight if you are in a hot or dry environment (3 x 1 = 3). Therefore, you would need to drink a total of 13 liters of water each day (4 + 6 + 3 = 13).

what is 3/5 into a percent?
3/5 = 0,6, it is 0.6 × 100 = 60%
Therefore, 3/5 is expressed as 60% in terms of percentage.
Percentage:
In mathematics, a percentage is a number or ratio that represents a fraction of 100. This is one way of representing a dimensionless ratio between two numbers. Other methods include ratios, fractions, and decimals. Percentage is often indicated by writing a "%" sign after the number.
According to the Question:
To convert a fraction to a decimal, it's always best to look at the denominator first. If the denominator only has prime factors of 2 and 5, you can easily pick a number multiplied by the denominator and convert it to a denominator that is a power of 10, and the result is the final prime number. If you have prime factors other than 2 and 5, converting to decimal takes longer and can result in infinite but repeating decimals.
In this case, the denominator is 5, so you can easily convert to decimal by multiplying the denominator and numerator by 2.
(3 × 20) / (5 × 20) = 60/100
Now,
To convert a fraction to a percentage, simply multiply by 100 and put a % sign next to the result.

An equilateral triangle shares a single side with a kite to form a new
quadrilateral, as shown below.
Calculate the size of angle p.
Give your answer in degrees (°).
Answer:
<P = 41
Step-by-step explanation:
we can consider this first figure as a quadrilateral and the trianlgle attached to be is equilateral triangle (as it is already shown in the figure that sides are equal)
we know that each angle of equalateral triangle is 60°
we can see that angle 79° is attached to it and even other angle is also attached
let the other angle be x
we can notice that x and the angle of equi triangle make a linear pair
so 180 - 60
= 120°
the opposite angle to the angle x will be also equal as angles on the same side of qual sides will be equal
now we know that total angle sum of quadrilateral is 360°
so
79 + 120 + 120 + <P = 360
319 + <P = 360
<P = 360 - 319
<P = 41

what is the definition for relation in math?
A relation in math is a set of ordered pairs containing two elements, one from each set. The first element is from the domain and the second from the range.
Relations can be expressed as a set of ordered pairs, as a graph, or as a mapping diagram. A function is a special type of relation in which, for every element in the domain, there is one and only one element in the range. This is expressed mathematically by stating that for every x in the domain, there is one and only one y in the range such that y = f(x). To calculate a relation, the domain and range values are paired with each other, and the ordered pairs are written down. For example, if the domain is {2,3,4,5} and the range is {7,8,9,10}, then the relation would be {(2,7),(3,8),(4,9),(5,10)}.

What is Multiplicative relationships?In mathematics, a multiplicative relationship between two variables means that the ratio of their values remains constant as the values of the variables change. In other words, the product of the two variables is a constant. For example, if we have two variables x and y such that xy = k, where k is a constant, then x and y have a multiplicative relationship. If we increase the value of one variable, we must decrease the value of the other variable proportion in order to maintain the constant product. This type of relationship is often seen in situations involving rates, ratios, and proportions, such as in growth or decay processes, population dynamics, and financial calculations.
In Table A, y is 2.5 times x, and in Table B, y is 3 times x. In both tables, the relationship between x and y is a constant ratio, which is a characteristic of multiplicative relationships. In Table A, the ratio of y to x is always 2.5, meaning that y is always 2.5 times greater than x. In Table B, the ratio of y to x is always 3, meaning that y is always 3 times greater than x. Therefore, both tables represent multiplicative relationships between x and y.

The height of flagpole a is 13.2 ft.
What is the height of flagpole c?

What do you mean by Distance?Distance is a numerical measurement of how far apart or how far away objects or locations are from each other. It is a physical quantity that is usually expressed in units such as meters, kilometers, miles, or feet. Distance is a scalar quantity, meaning it only has magnitude and no direction.
The distance between two points is typically calculated using a formula, such as the distance formula in Euclidean geometry, which involves taking the square root of the sum of the squares of the differences in the coordinates of the two points.
Let's start by drawing a diagram of the situation:
A

We can see that the triangles ASC and ABC are similar, since they have the same angles (90 degrees at S and a common angle at A). Therefore, we can use proportions to find the height of flagpole C:
AC SC
-- = --
AB AS
Substituting the given values, we get:
AC 10
-- = --
AB AB + 12
We can solve for AB by noting that the height of flagpole A is the sum of the heights of AB and BC:
13.2 = AB + BC
Solving for BC, we get:
BC = 13.2 - AB
Substituting this into the first equation, we get:
AC 10
-- = --
AB AB + 12
AC = 10(AB)/(AB + 12)
Now we can substitute the value we found for AB:
AC = 10(13.2 - BC)/(13.2 - BC + 12)
AC = 10(13.2 - BC)/25.2
We still need to find BC, which we can do by using the fact that the triangles ABC and ASC are similar:
BC/AB = SC/AS
Substituting the given values, we get:
BC/AB = 10/22
BC = 10AB/22
Substituting this into the equation for AC, we get:
AC = 10(13.2 - 10AB/22)/25.2
Now we can solve for AB:
13.2 = AB + 10AB/22
AB = 7.92
Finally, we can substitute this into the equation for AC:
AC = 10(13.2 - 10(7.92)/22)/25.2
AC = 6.1
Therefore, the height of flagpole C is approximately 6.1 feet.

Laurel needs to make an open-topped box to hold a gift for
her friend Kim. She has a sheet of cardboard 10 cm long by
16 cm wide. She plans to make the box by cutting squares
from the corners and folding up the sides. What is the
length of a side of each square that should be cut out to
give a box of maximum volume?
Answer:
To find the length of a side of each square that should be cut out to give a box of maximum volume, we need to use optimization. Let's call the length of each square x cm.
To form the box, we will cut out squares of side length x from each corner of the rectangular cardboard sheet, and then fold up the sides to form the box. The dimensions of the base of the box will be (10-2x) cm by (16-2x) cm, and the height of the box will be x cm.
Therefore, the volume of the box will be:
V = (10-2x) * (16-2x) * x
V = 4x^3 - 52x^2 + 160x
To find the length of a side of each square that should be cut out to give a box of maximum volume, we need to find the value of x that maximizes V. To do this, we can take the derivative of V with respect to x, and set it equal to 0:
dV/dx = 12x^2 - 104x + 160 = 0
We can solve for x by factoring the quadratic expression:
3x^2 - 26x + 40 = 0
(3x - 10)(x - 4) = 0
So the critical points are x = 10/3 and x = 4. Since we're looking for a maximum, we need to find which of these critical points gives the highest value of V. We can do this by evaluating V at both points:
V(10/3) ≈ 51.85
V(4) = 128
Therefore, the value of x that gives the maximum volume is x = 4 cm.
So we should cut out squares of side length 4 cm from each corner of the cardboard sheet to make a box of maximum volume.
The requried maximum height of the box should be 2 for the maximum volume.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
Let the side measure of the square cut b x,
Now,
The length of the box will be = 16 - 2x
width of the box will be = 10 - 2x
The height of the box will be = x
The volume of the box is given as,
V = (16-2x)(10-2x)(x)
V = 4x³ - 52x² + 160x
Differentiate the above equation with respect to x,, and equate it to zero to get the maximum value of x for the maxium volume,
12x² - 104x + 160 = 0
x = 2 and 6.667
We can neglect x = 6.667 because at 6.667 the volume has a negative magnitude.
Thus, the requried maximum height of the box should be 2 for the maximum volume.

Jane is choosing between two exercise routines. In Routine # 1, she burns 22 calories walking. She then runs at a rate that burns 5.75 calories per minute. In Routine #2, she does only running, burning 8.5 calories per minute. For what amounts of time spent running will Routine #1 burn at least as many calories as Routine #2? Use t for the number of minutes spent running, and solve your inequality for t.
Answer: 3.8 minutes!
Step-by-step explanation:
The answer is 3.8 minutes. To solve for t, we need to set up an inequality where the calories burned in routine #1 is equal to or greater than the calories burned in routine #2. We can write this as 22 + 5.75t ≥ 8.5t. Then, we can subtract 8.5t from both sides to get 22 ≥ -2.75t. Finally, we can divide both sides by -2.75 to get t ≤ -8/2.75, which simplifies to t ≤ 3.8. Therefore, Jane needs to run for 3.8 minutes in Routine #1 in order to burn at least as many calories as Routine #2.
Answer:
Jane needs to run for 8 minutes or less in Routine #1 for it to burn at least as many calories as Routine #2. If she runs for more than 8 minutes in Routine #1, then Routine #2 will burn more calories.
Step-by-step explanation:
In Routine #1, the total number of calories burned is:
C1(t) = 22 + 5.75t
The first term represents the calories burned while walking, and the second term represents the calories burned while running.
In Routine #2, the total number of calories burned is:
C2(t) = 8.5t
This represents the calories burned while running, as there is no walking in Routine #2.
We want to find the values of t for which C1(t) is greater than or equal to C2(t). So we can set up the following inequality:
C1(t) ≥ C2(t)
Substituting the expressions for C1(t) and C2(t), we get:
22 + 5.75t ≥ 8.5t
Simplifying the inequality, we get:
22 ≥ 2.75t
Dividing both sides by 2.75, we get:
t ≤ 8
So Jane needs to run for 8 minutes or less in Routine #1 for it to burn at least as many calories as Routine #2. If she runs for more than 8 minutes in Routine #1, then Routine #2 will burn more calories.
