The total area of three walls, each 8' feet high; 14, long, and other is 10' long?
Answer:
304 feet²
Step-by-step explanation:
Given three walls :
First wall : 8 feets high ; 14 inches long
Second wall : 8 feets high ; 14 inches long
Third wall : 8 feets high ; 10 feets long
Area = Length * height
Area = (8 * 14) = 112 ft²
Area = (8 * 14) = 112 ft²
Area = (8 * 10) = 80 ft²
Total area :
(112 + 112 + 80) ft²
= 304 feet²
A scale model of an object has a scale of 1 cm : 2 ft. The actual object is 11 feet tall. How tall is the model?
Answer: The model is 69.420 feet tall.
Step-by-step explanation: I asked my teacher.
Answer:
5.5 cm
Step-by-step explanation:
If you take 11 and divide it by 2 you would get 5.5cm. This is the answer because If 1cm is 2 ft you divide it by the actual height and you end up with how tall the model would be.

Answer:
d = 50h
Step-by-step explanation:
We are using the linear property y = mx.
We know that distance = rate × time, so if we subsitute this, we get that the distance is d, the rate is 50 mph, and the time is h.
Therefore, we can form the equation d = 50h.
the mean of 16,18,x,12 and 15 calculate the value of x
Answer:
29
Step-by-step explanation:
Mean = sum of datas/Sample size
Given the data 16,18,x,12 and 15
Sum = 16+18+x+12
Sum = 46+x
Mean = 15
Sample size = 5
Substitute
15 = 46+x/5
15 * 5 = 46+x
75 = 46 + x
x = 75-46
x = 29
Hence the value of x is 29

A market research analyst claims that 32% of the people who visit the mall actually make a purchase. You think that less than 32% buy something and decide to test the claim. You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase. The value of the test statistic is about:
A. 1.74
B. 1.60
C. 1.48
D. -1.60
E. -1.48
Answer:
E. -1.48
Step-by-step explanation:
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the expected value, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
A market research analyst claims that 32% of the people who visit the mall actually make a purchase.
This means that:
[tex]\mu = 0.32[/tex]
[tex]\sigma = \sqrt{0.32*0.68} = 0.4665[/tex]
You stand by the exit door of the mall starting at noon and ask 82 people as they are leaving whether they bought anything. You find that only 20 people made a purchase.
This means that [tex]n = 82, X = \frac{20}{82} = 0.2439[/tex]
The value of the test statistic is about:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]t = \frac{0.2439 - 0.32}{\frac{0.4665}{\sqrt{82}}}[/tex]
[tex]t = -1.48[/tex]
So the correct answer is given by option E.

A toy rocket is shot vertically into the air from a launching pad 8 feet above the ground with an initial velocity of 72 feet per
second. The height h, in feet, of the rocket above the ground at t seconds after launch is given by the function
h(t) = - 1612 + 72t + 8. How long will it take the rocket to reach its maximum height? What is the maximum height?
The rocket reaches its maximum height at second(s) after launch.
(Simplify your answer.)
The maximum height reached by the object is feet.

THE amusement park won't allow kids to ride roller-coasters until they are a minimum of 48 inches tall. Michael is now 42 inches tall, and grows about 1/2 inch every month. How many months will it be until Michael can read a roller coaster? Please show me the individual steps?
Answer: It will one year (or 12 months) before Michael is able to ride the roller coaster.
Step-by-step explanation: Because he grows a half inch every month, this means that It takes him two months to grow one full inch. Because he has to grow six inches, you just multiply 2 by 6 to get 12 months or one year.
Answer:
48-42=6, which is how much Michael needs to grow.
1/2x=6, where x is the number of months
x = 12 months.
1 year = 12 months so the answer is one year.
