L=12.5
W=32.25
Volume=8223.75
Answers
Answer:
20.4
Step-by-step explanation:
The formula to find the volume of a rectangular prism is :
Volume = length × width × heightGiven that,
Volume = 8223.75 in³
length = 12.5 in
width = 32.25 in
height = ?
Now let us use the formula and find the height.
V = l × w × h
8223.75 = 12.5 × 32.25 × h
8223.75 = 403.125h
Divide both sides by 403.125.
20.4 = h
Therefore,
height = 20.4 in

Since it’s given the student chose to fly as their superpower, you only look at the total males in that row.
The probability that the student was male, given the student chose to fly as their superpower is 2/3.
What is a conditional relative frequency?It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell by the total frequency.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
Total females = 48
Females and invisibility = 32
P(invisibility/female) = 32/48
= 2/3
Thus, the probability that the student was male, given the student chose to fly as their superpower is 2/3.

Matthew bought 2 movie tickets for $11, and Rosa bought 7 movie tickets for $38.50. What is the constant of proportionality?
Answers
Answer:
You should multiply 5.5 by 7 and it is equal to 38.5 so it is D
explanation:
did the test hope this helps! :D
The constant of proportionality of the given condition is 5.5.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Let's say Matthew and Rosa's constant of proportionality is K.
Now,
Matthew bought 2 movie tickets for $11.
So,
11 ∝ 2
11 = K 2 ⇒ K = 5.5
Now,
Rosa bought 7 movie tickets for $38.50.
So,
38.50 ∝ 7
38.50 = K 7 ⇒ K = 5.5
Hence "The constant of proportionality of the given condition is 5.5".

hours are factored in
The hourly rates $2
Answers
Answer:
C. There is a $2 fee to park, before the number of hours are factored in.
Step-by-step explanation:
Given that the equation, [tex] y = 3x + 2 [/tex], represents total cost charged for at a parking lot for customers to park their car, thus:
the "x" represents the number of hours,
3 represents the charged fee per hour
2 represents the flat fee charged, which is the starting fee, before the number of hours is calculated and added.
Therefore, the answer is "C. There is a $2 fee to park, before the number of hours are factored in."

Answer:
y = 6x + 4
Step-by-step explanation:
We know the equation is linear. First, use two points to find the slope of the line.
m = (y₂ − y₁) / (x₂ − x₁)
m = (10 − 4) / (1 − 0)
m = 6
The y-intercept is 4. So the equation of the line is:
y = mx + b
y = 6x + 4

what the heck I went ahed to my teacher and asked her what P versus NP. is and I don't know what it is and she walked away please help me
Answers
Answer:
The P versus NP problem is a major unsolved problem in computer science. It asks whether every problem whose solution can be quickly verified can also be solved quickly.
P is the set of problems whose solution times are proportional to polynomials involving N's. ... NP (which stands for nondeterministic polynomial time) is the set of problems whose solutions can be verified in polynomial time. But as far as anyone can tell, many of those problems take exponential time to solve.
miles has 25 coins In his pocket. Some are Nichols and some are dimes. He has a total of $1.65 how many of each type of coin does he have?
Answers
▪ Answer:
n = 17
d = 8
▪ Step-by-step explanation:
Hi there !
1 nickel = 5c
1 dime = 10c
$1.65 = 165c
n + d = 25 => n = 25 - d
5n + 10d = 165
replace n
5(25 - d) + 10d = 165
125 - 5d + 10d = 165
5d = 165 - 125
5d = 40
d = 8 (dimes)
n = 25 - d
n = 25 - 8
n = 17 (nickels)

3. A playground designer wanted to place a fountain so that it was close to both the slide and the swings.
Refer to the coordinate grid shown. Each unit on the grid represents 5 ft.
(a) Find the distance from the fountain to the slide. Show your work.
(b) Find the distance from the fountain to the swings. Show your work.
Answers
Answer:
Part A:
10ft
Part B:
35ft
Step-by-step explanation:
• Since we know that an increase of 1 on either the x, or y value is equal to 5 feet, we can form an equation where x = the amount that the value increased, so since the fountain is at (-2, -2) and the slide is at (-2, 0), we see that there is an increase of 2 to the y-value, meaning our equation should now be 5(2) which equals 10.
• Because we use 5x and 5y to solve this, we can already see how to do this. If the swings are at (5, -2) and the fountain is at (-2, -2), we can see that there was an increase of 7 on the x-value, meaning that our equation would now be 5(7), which equals 35.
