Answer: 242.7 square inches
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
The first model has a height of 5 inches and a surface area of 80.9 square inches:
The proportion is : height/ surface area= 5 in / 80.9 in2
For a height of 15 inches
15 in/ x in2
So:
5/80.9 = 15/x
x= 15/ (5/80.9 )
x= 242.7 square inches

Answer: Choice D) [tex]2\sqrt{5}[/tex]
===========================================================
Work Shown:
Point A starts at (-2,3) and moves to (2,5) after applying the translation rule of "shift 4 to the right, 2 up".
Use the distance formula to find the distance from (-2,3) to (2,5)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-2-2)^2 + (3-5)^2}\\\\d = \sqrt{(-4)^2 + (-2)^2}\\\\d = \sqrt{16 + 4}\\\\d = \sqrt{20}\\\\d = \sqrt{4*5}\\\\d = \sqrt{4}*\sqrt{5}\\\\d = 2\sqrt{5}\\\\d \approx 4.472136\\\\[/tex]

Answer:
steps
1) 14/28 to convert to a percent you have to first divide the numerator from the demoninator and then you multiply by 100 and you get get %50 (you could had known bc 14 is half of 28)
2) 5/28 do the same thing as the first step and get %17.85

The director of health services is concerned about a possible flu outbreak at her college. She surveyed
100 randomly selected residents from the college's dormitories to see whether they had received a
preventative flu shot. The results are shown below. What is the probability that a dormitory resident
chosen at random from this group has had a flu shot, given that he is male?
A)51/100
B)39/100
C)39/80
D)13/17
Answer:
39/100
Step-by-step explanation:
The question asks to find the probability that a dormitory resident
chosen at random from this group has had a flu shot, given that he is male.
As for that, the first thing to do is to look at the column where it says male.
Male:
39-Had Flu Shot
12-Did not have Flu Shot
Since the question is asking for the total number of males who did get a flu shot, it would be 39.
Lastly, to find probability, you have to use part over whole. The part would be 39. The whole would be the number of people selected to be tested. Therefore, the whole would be 100. That is why the probability that a dormitory resident chosen at random from this group has had a flu shot, given that he is male would be 39/100.
Answer:
39/100

-7 2/3+(-5 1/2) +8 3/4 sorry I'm to stupid to figure this out
A positive and a negative become a negative. First you convery the mixed fraction into an improper fraction, then you find the common denominator of all fractions, next step according to PEMDAS, you can add and subtract in any order you would like too.
1. -7 2/3 - 5 1/2 + 8 3/4
2. -23/3 - 11/2 + 35/4
3. -92/12 - 66/12 + 105/12 The common denominator is 12.
4. -92/12 - 66/12 = -158/12 A negative and a negative is addition but just add the negative sign.
5. -158/12 + 105/12 = -53/12 =
Answer= -4 5/12
This is my way of doing it but according to PEMDAS any other order of doing it is fine also!
Suppose the equation h =− 16t2 + 35t models the altitude a football will reach t seconds after it is kicked. Is it possible for the football to reach 16 ft in the air? Justify your answer.
Answer:
The ball will be able to reach the 16 ft.
Step-by-step explanation:
In order to calculate if the ball will be able to reach that height, we must make "h" equal to 16, if there's a real positive solution, then the ball will be able to reach it.
16 = -16t² + 35t
16t² - 35t + 16 = 0
t = [-(-35) +- sqrt((-35)² - 4*16*16)]/(2*16)
t = [35 +- sqrt(1225 - 1024)]/32
t = [35 +- sqrt(201)]/32
t = (35 +- 14.177)/32
t1 = 0.65071875
t2 = 1.5367
The ball will reach that height at 0.65 s and 1.53 s.

Brett is comparing the graphs of y = 2X and y = 5x. Which statement is true?
The correct question is:
Brett is comparing the graphs of y = 2^x and y = 5^x. Which statement is true?
(1) The y-intercept of y = 2^x is (0,2), and the y-intercept of y = 5^x
is (0,5). [
(2) Both graphs have a y-intercept of (0,1), and y = 2^x is steeper.
(3) Both graphs have a y-intercept of (0,1), and y = 5^x is steeper.
(4) Neither graph has a y-intercept.
Answer:
(2) and (3) are true.
Step-by-step explanation:
The correct options are:
(2) Both graphs have a y-intercept of (0,1), and y = 2^x is steeper. Since X < 0

A circle has a radius of 5/3 units and is centered at (9.2 -7.4)
Write the equation of the Circle.
Answer:
(x - 9.2)^2 + (y + 7.4)^2 = (5/3)^2
Step-by-step explanation:
We start with (x - h)^2 + (y - k)^2 = r^2. The center is (h, k) and the radius is r.
Then we have:
(x - 9.2)^2 + (y + 7.4)^2 = (5/3)^2

Answer:
Tuesday, 1: 30 pounds
Tuesday, 2: 40% of the apples
Tuesday, 3: x ( or any variable) + 8
Tuesday, 4: 9a-3b
Step-by-step explanation:
Since she weighs 38% of the normal weight, you multiply the decimal form to the original weight, which is 78. So .38 multiplied by 78 is 29.64, and rounding it to the nearest pound would make it go up to 30.
38%=.38
.38 x 78=29.64
29.64 rounded = 30
If 3/5 of the apples are ripe, that means that 2/5 are not. An easy way to turn this fraction into a percent is to make the number out of 100. Since 5 x 20 is 100, you multiple both the numerator and denominator by 20. 2 x 20 is 40, 5 x 20 is 100, hence 40/100. The numerator will be the percentage.
5/5-3/5 = 2/5
2/5 x 20/20 = 40/100
40/100 = 40%
The unknown score would become a variable, and since its increasing by 3 it is +8.
Since the perimeter is adding all sides, you'd add all of the equations. The 3a's times 3 would be 9a, and the -b would become -3b.
3a - b + 3a - b + 3a - b
9a - b - b - b
9a - 3b

5(7 + 3x) - 12 how to simplify
To solve this we need to use this formula:
a(b+c)=ab+ac
5(7+3x)-12=35+15x-12=15x+23
Answer:
Step-by-step explanation:
Multiply the 5 to the 7 and 3x--> 35 + 15x -12. Then add 12 to the -12, making it 0 (inverse operations), and add 12 to the 35 making it 47 + 15x. :) Then you would simply divide the 15 by 15x (making the variable by itself). your answer for x should be 47/15. :> If I helped, please mark brainliest!!
