Sara and 3 of her friends went to lunch one day. Each person paid for her own lunch, but they agreed to split the tip. If the tip amount was 15% of the total, and the 4 lunches totaled $60, what was the portion of each person’s tip amount?

Answer:

5^2 would be 5*5 =25 so 5^2 is 25

Step-by-step explanation:

The number of points Jim scored is 15 points.

The number of cars given the ratio of car to boat is 140 cars

Total points = Number of points Kevin has + Number of points Jim has

22 = x + (8 + x)

22 = x + 8 + x

22 = 2x + 8

22 - 8 = 2x

14 = 2x

divide both sides 2

x = 14/2

x = 7

Number of points Jim has = 8 + x

= 8 + 7

= 15 points

Part B:

Boat : car

2 : 5 = 56 : x

2/5 = 56/x

cross product

2 × x = 56 × 5

2x = 280

divide both sides by 2

x = 280/2

x = 140

Therefore, the number of points Jim scored is 15 points and the number of cars is 140

The result is commonly known as just a square number, a complete square root, or simply "a square" when such an integer (a "whole" number), either positive, negative, or zero, is multiplied on its own. So now all square integers are 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on.

It is possible to multiply an integer by its square root in order to obtain the original value. Square root of, end square root is the symbol for this mathematical concept. Contrary to squaring, finding a number's square root is the reverse.

For instance, 3 is squared at 9, 32, and its square root at 9, which is 9, is equal to 3. It is simple to multiply by 9 since it is a perfect square.

The graph of f(x)=√x could be transformed to form the graph of g(x)=√x+4 c) vertical shift of 4 units up.

When functions are changed, the graph's representational curve "moves to the left/right/up/down," "expands or compresses," or "reflects."

A vertical movement of 4 units up is the explanation for how the graph of f(x)=x might be changed to become the graph of g(x)=x+4.

Translations, reflections, and dilations are the three different forms of transformations. A function can be transformed in one of two ways: vertically (affecting the y-values) or horizontally (affects the x-values). The function's equation, which includes the four transformation variables, is shown below (a, b, h, and k).

Yes, the coefficient of thermal expansion goes to zero at T approaches zero.The coefficient of thermal expansion is defined as the fractional change in volume per unit change in temperature.

The coefficient of thermal expansion is defined as the fractional change in volume per unit change in temperature. It is calculated by taking the derivative of volume with respect to temperature. Mathematically, it is expressed as β = (1/V) (dV/dT). As the temperature approaches zero, the change in volume (dV) will also approach zero, and thus the coefficient of thermal expansion (β) will approach zero as well.

The complete question : thermal expansion goes to zero at T approaches zero. By definition, the volume coefficient of thermal expansion is: beta = (1/V) (dV/dT). So, as T approaches zero, (dV/dT) approaches zero, and thus beta approaches zero.

Answer: In order to solve this problem, you should use the Pythagorean theorem. Since FG is perpendicular to OP, and OP and OQ are radii of the same circle, then triangle OFG is a right triangle. Similarly, triangle ORS is also a right triangle. By using the Pythagorean theorem, you can find that:

OF = sqrt(OP^2 + FG^2) = sqrt(19^2 + 40^2) = sqrt(361 + 1600) = sqrt(1961)

and

OS = sqrt(OQ^2 + RS^2) = sqrt(19^2 + 37^2) = sqrt(361 + 1369) = sqrt(1740)

Therefore, the length of the segment connecting the feet of the altitudes is:

OF + OS = sqrt(1961) + sqrt(1740) = 27.2

[tex] \sf \: 12th \: term = 37[/tex]

Step-by-step explanation:

Common difference (d) is,

→ d = a2 - a1

→ d = -3 - (-7)

→ d = -3 + 7

→ [ d = 4 ]

Now the 12th term will be,

→ a1 + (d × (n - 1))

→ -7 + (4 × (12 - 1))

→ -7 + (4 × 11)

→ -7 + 44

→ 37 => 12th term

Hence, the answer is 37.

The concept given is Sampling, which selects the group that you will actually collect data from in your research. The answer is option B, ​True; because it is often the case that the individuals who volunteer do not accurately represent the population.

Sampling is the selection of a subset of individualities from within a statistical population to estimate the characteristics of the whole population. Statisticians essay to collect samples that are representative of the population in question.

Frequently, voluntary response samples oversample people who have strong opinions and under-sample people who do not watch important about the content of the check. Therefore consequences from a voluntary response sample aren't as secure as conclusions grounded on an arbitrary sample of the entire population under consideration.

Volunteer slice doesn't induce a representative sample, so, thus, would not be the favored choice of experimenters who were keen to be suitable to generalize their data to the whole population.

Step-by-step explanation:

See attached worksheet.

Guidelines are presented on how to both graphically and mathematically solve for the equation.  

Graphing:  Mark the the two given points and connect them with a ruler to form the line.  These same two points may be used to determine the slope, as is shown.  The slope is 2.  The line intersects the y axis at 3, so the y-intercept is 3.  Using the standard form of an equation, the line is y = 2x + 3, as is outlined in the attachment.

The same line is determined mathematically by using the same technique for calculating slope.  The value of the y-intercept may be found by using one of the two given points in the equation that has the slope of 2:

  y= 2x +b

Enter pont (-1,1), for example, and calculate the value of b. b = 3, (since 1 = 2*(-1)+ b, so b=3).

The equation of this line is y=2x+3

The 100th prime number is 541.

Therefore the answer is 541.

Prime numbers are numbers that are divisible by only 1 and themselves. They are considered to be the "building blocks" of the natural numbers, and are important in number theory and other branches of mathematics.

Prime numbers are fundamental for number theory and have a lot of applications in cryptography, coding theory, and other areas of mathematics.

The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. The primes continue indefinitely, with no repeating pattern or predictable distribution. Finding the nth prime number is not an easy task, it requires knowledge of number theory and a lot of computational power.

In general, the nth prime number grows faster than any polynomial in n. The 100th prime number is larger than the 100th Fibonacci number (which is about 354) and smaller than the 100th triangular number (which is about 5050).

The area of the triangle is 54 square cm.

To find the area of a triangle, we can use Heron's Formula, which states that the area of a triangle is equal to the √ (s * (s-a) * (s-b) * (s-c)), where s is the semi-perimeter of the triangle and a, b, and c are the sides of the triangle.

Step 1: Find the semi-perimeter of the triangle. s = (9 + 12 + 15) / 2 = 21 / 2 = 10.5

Step 2: Substitute the semi-perimeter and the sides of the triangle into Heron's Formula.

Area =  √(10.5 × (10.5 - 9) × (10.5 - 12) × (10.5 - 15))

Step 3: Simplify the equation.

Area = √ (10.5 × 1.5 × -1.5 × -4.5)

Step 4: Perform the square root.

Area = √ -94.5 = 54 square cm.
