A parking lot is 400 yards long and 300 yards wide. You would want to make a miniature version
of this in your production design course. If you make it 10 inches long, how wide should it be?
If the scale I make for the parking lot is 10 inches long, it should be 7.5 inches wide.
What is a scale?Scale is a term to refer to a drawing and design method in which an object or space and its actual measurements are taken as a reference and subsequently reduced or increased while maintaining the proportions between their measurements.
How to calculate the length of the width of the parking lot to scale?To calculate the width of the parking lot to scale, it is necessary to perform the following mathematical operation.
We need to figure out how much 100 yards is on the inch scale model. So if 400 yards is 10 inches we must divide this value by 4 as shown below:
10 ÷ 4 = 2.5Based on the above, 100 yards equals 2.5 inches on this model. So if your width is 300 yards, the length in inches would be 7.5 inches.

The U.S. government has devoted considerable funding to missile defense research over the past 20 years. The latest development is the Space-Based Infrared System (SBIRS), which uses satellite imagery to detect and track missiles ( Chance, Summer 2005). The probability that an intruding object (e.g., a missile) will be detected on a flight track by SBIRS is 0.8. Consider a sample of 20 simulated tracks, each with an intruding object. Let x equal the number of these tracks on which SBIRS detects the object. (a) Is x (approximately) a binomial random variable? Group of answer choices No Yes
Answer: Yes
Step-by-step explanation:
Given that :
Probability of success (p) = 0.8
Number of simulations (n) = 20
Number of tracks on which infrared system detects object = x
To test if it is binomial random variable :
For a binomial distribution :
P(x) = nCx * p^x * (1 - p)^(n-x)
Since the variables given are enough to create and use a binomial probability distribution, then x is approximately a binomial random variable.
You deposit $750 into a bank account. The bank pays a simple interest rate of 3%. How much interest have you earned
after three years?
Answer:
You have earned $67.50
Step-by-step explanation:
Since we are working with simple interest, we will use this formula:
[tex]I=Prt[/tex],
where P represents the principal amount (your deposit), r represents the rate as a decimal, and t represents the time in years. First, we need to rewrite our interest as a decimal by dividing 3% by 100:
[tex]3\div 100 = 0.03[/tex]
Now, we also know the values of P and t from the problem:
[tex]P=750\\r=0.03\\t=3[/tex]
We can substitute those values into the formula:
[tex]I=750(0.03)(3)\\I=67.5[/tex]
In context, that means you earned $67.50 in interest.

• Can you list down similarities of your experience with your circle of friends?
A recent study published in Nature Communications says the reason for this likeness is that best friends actually have similar — or sometimes identical — brain activity.. Yup , your closest friends "get you" because it's like their basically looking in the mirror.. Friends and tend to have certain characteristics in common , Such as Age, Education and even intelligence — and yet , Research has long suggested that personality isn't one of these commonalities.. Some scientific research has shown how you're likely to be attracted to people who share similar facial characteristics as you. One theory for this is that we associate people who look like us with our parents, and thus have more positive feelings towards their features. Similarities are also important for friendships.A ladybug and ant move at constant speeds. The diagrams with tick marks show their positions at different times. Each tick mark represents 1 centimeter. Lines u and v also show the positions of the two bugs. Which line shows the ladybug’s movement?
Answer:
Line u shows the movement of the ladybug. Because line v goes farther than line u
Step-by-step explanation:
Because line v goes farther than line u
The ladybug's motion is depicted in line u. Because line v is moving farther than line u.
What is Speed?The amount of the shift in approach per unit of time or the size of the displacement over time for an object can be used to describe speed, which would be a scalar quantity in everyday language and kinematics.
The maximum speed that can be maintained when a period grows closer to zero is the starting speed.
By dividing the object's distance traveled by the duration of the interval, the mean pace of the object for the given period is calculated. Speed and velocity are not always the same thing.
The line u and v show the position of the two bugs, but the line that shows the ladybug's movement is line u because line v is moving farther than line u.

1. GENERALIZE Think about quadrilaterals and rotational symmetry. Write some generalizations of your own about rotational symmetry and quadrilaterals.
Answer:
Step-by-step explanation:
It is a little vague on what the expected answer is. But for quadrilaterals, any rotational symmetry will be along a line that divides the quadrilaterals in two equal halves. This is due to symmetry.
Also the two equal halves will be mirror image of each other at the axis of symmetry. It is again due to properties of symmetry.
Lastly rotating a quadrilateral along its axis of rotational symmetry will create a 3-D cylindrical shape. A cross-section of that shape along the axis will show the same quadrilateral.

How long is the minute hand on a clock whose tip travels 15 cm from 1:15 to 1:30 to the nearest tenth?
10.1 cm
9.6 cm
6.0cm
0.2 cm
We will see that the length of the minute hand is 9.6 cm.
How long is the minute hand?
We know that for a circle of radius R, the length of the arc defined by an angle of θ is:
L = θ*R
In this case, the length of the arc is 15 cm, and the angle is the one between 1:15 and 1:30, which is one-fourth of a complete circle.
If a complete circle has an angle of 2pi, then one-fourth of a circle has an angle θ = (2pi)/4 = pi/2
Then, replacing the length of the arc and the angle we have:
15cm = (pi/2)*R
Now we can solve this for R, remember that pi = 3.14:
(15 cm)*(2/3.14) = R = 9.6cm
So the length of the minute hand is 9.6 cm.
So the correct option is the second one.

The length of a rectangle is 5 less than twice the width. What values of the width will make the area less than 150 square feet? Define your variable(s). Write inequalities that could be used to solve this problem. Then solve the problem.
Answer: Anything between 0 and 10, excluding both endpoints.
In terms of symbols we can say 0 < w < 10 where w is the width.
===================================================
Explanation:
You could do this with two variables, but I think it's easier to instead use one variable only. This is because the length is dependent on what you pick for the width.
w = width
2w = twice the width
2w-5 = five less than twice the width = length
So,
width = wlength = 2w-5which lead to
area = length*width
area = (2w-5)*w
area = 2w^2-5w
area < 150
2w^2 - 5w < 150
2w^2 - 5w - 150 < 0
To solve this inequality, we will solve the equation 2w^2-5w-150 = 0
Use the quadratic formula. Plug in a = 2, b = -5, c = -150
[tex]w = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\w = \frac{-(-5)\pm\sqrt{(-5)^2-4(2)(-150)}}{2(2)}\\\\w = \frac{5\pm\sqrt{1225}}{4}\\\\w = \frac{5\pm35}{4}\\\\w = \frac{5+35}{4} \ \text{ or } \ w = \frac{5-35}{4}\\\\w = \frac{40}{4} \ \text{ or } \ w = \frac{-30}{4}\\\\w = 10 \ \text{ or } \ w = -7.5\\\\[/tex]
Ignore the negative solution as it makes no sense to have a negative width.
The only practical root is w = 10.
If w = 10 feet, then the area = 2w^2-5w results in 150 square feet.
----------------------
Based on that root, we need to try a sample value that is to the left of it.
Let's say we try w = 5.
2w^2 - 5w < 150
2*5^2 - 5*5 < 150
25 < 150 ... which is true
This shows that if 0 < w < 10, then 2w^2-5w < 150 is true.
Now try something to the right of 10. I'll pick w = 15
2w^2 - 5w < 150
2*15^2 - 5*15 < 150
375 < 150 ... which is false
It means w > 10 leads to 2w^2-5w < 150 being false.
Therefore w > 10 isn't allowed if we want 2w^2-5w < 150 to be true.
A bottle contains 125 multivitamin tablets. Each tablet contains 20 milligrams of niacin.
How many grams of niacin in all are contained in the bottle?
Answer:
There are 2.5 grams of niacin contained in the bottle.
First you have to find how many milligrams are in the bottle.
So you multiply 125 by 20 since there are 125 tablets and 20 milligrams in each one.
125*20=2500
So there are 2500 milligrams in the bottle. Then you have to convert it into grams. To do that you divide the mass by 1000.
2500/1000=2.5
So there are 2.5 grams in the bottle.
Step-by-step explanation: hope this helps :)
Answer:
2.5
Step-by-step explanation:
125 vitamins, each vitamin has 20 milligrams. convert 20 milligrams to grams. 0.02 grams of niacin in each vitamin. 125 multiplied by 0.02 is 2.5
let f(x)=3-3x+5x^2.calculate the following.
f(a)=

f(a+h)-f(a)/h= for h≠0
Answer & step-by-step explanation:
[tex]f(a)[/tex] is simply calculating by replacing a in lieu of x
[tex]f(a) = 3-3a+5a^2[/tex]
Same difference for [tex]f(a+h)[/tex], just be careful with products and squares:
[tex]f(a+h) = 3-3(a+h)+5(a+h)^2 = 3-3a-3h+5a^2+10ah+5h^2 = 3-3a+5a^2 -3h+10ah+5h^2[/tex]
In the last step i just reorganized terms so that everything containing h was at the end.
Finally, for the incremental ratio, writing it as 1/h for the sake of font sizes:[tex]\frac{f(a+h)-f(a)}h = \frac1h[(3-3a+5a^2-3h+10ah+5h^2)-(3-3a+5a^2)]=\\\frac1h(-3h+10ah+5h^2) = 10a-3 +5h[/tex]
