Answer:
15 in.
Step-by-step explanation:
Volume of rectangular prism = length × width × height
Length = 30 in
Width = 20 in
Height = x
Volume of rectangular prism = 9000 in³
Volume of rectangular prism = length × width × height
9000 = 30 × 20 × x
9000 = 600x
x = 9000/600
x = 15 in
Answer:
15
Step-by-step explanation:
the formula of finding the volume of a rectangular prism is base times height. the base dimensions are 20*30 so its 600 square inches, 9000/600=15.

A jar contains 5 blue marbles, 1 yellow marble, and 4 green marbles. What is the probability of randomly choosing a yellow marble, replacing it , and then choosing a yellow marble again
Answer:
1/100
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
the probability = (number of yellow marbles / total number of marbles) x (number of yellow marbles / total number of marbles)
total number of marbles = 1 + 5 + 4 = 10
(1/10) x (1 / 10) = 1 /100

On an architect's drawing, the scale is 1 inch equals 6.5 feet. The distance on the drawing of the width of the dining room is 3.5 feet. How wide is the actual dining room?
Answer:
22.75
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
3.5 x 6.5 = 22.75 ft

A rectangle has a length that is twice the width. The width is to be extended by 5 ft and the length by 3 ft, so the total area becomes 99 square feet. What was the original length?
Answer Choices:
4 ft
6 ft
8 ft
10 ft
12 ft
14 ft
16 ft
Answer:
8 feet
Step-by-step explanation:
w = width
2s = length
Find 'w' by multiplying the new dimensions:
(w+5)(2w+3) = 2w² + 3w + 10w + 15 = 99
simplify:
2w² + 13w - 84 = 0
Factor:
(2w + 21)(w - 4) = 0
w = -21/2 ** disregard because a measurement cannot be negative **
w = 4
original width was 4
orginal length was twice 4 or 8 feet

Two equations are given. m + 5n = 20
m = n-4
What is the solution to the set of equations in the form (m, n)?
A (3,7)
B (0,4)
C (5, 1)
D (2,6)
Please help
Answer:
B. (0, 4)
Step-by-step explanation:
so we need to find the value of m and n, and luckily we have 2 equations that'll help. (I'm going to use the substitution method for this instead of the Elimination method because I am lazy)
first we need to solve for m, but we already have an equation that tells us what m is equal to, m = n - 4.
now we just need to plug in our new m into the other equation and solve for n. (we are using m + 5n = 20 for that)
so now we get
(n - 4) + 5n = 20
so we solve for n
n + 5n = 24
6n = 24
n = 4
now that we know that n is 4, we can plug that into our m equation (m = n - 4)
m = 4 - 4
m = 0
now we have our m and n, and we can make our ordered pair.
(m, n)
(0, 4)
solve for the value of k
Answer:
k = 42
Step-by-step explanation:
This is a complementary angle, meaning that the angles formed equal 90 degrees. We know it is complementary because the angle is shown was a tiny square, a sign that it is 90 degrees. Thus, the two angles (k+1) and 47 added together must equal 90. So, we can write an equation:
(k+1) + 47 = 90
k + 1 = 43
k = 42.

A cylinder has a height of 10 ft and a volume of 25,456 ft³.
The radius of the cylinder is approximately ___ feet.
Round your answer to the nearest whole number.
Answer:
The radius of the cylinder is approximately 28 feet.
Step-by-step explanation:
Volume of a cylinder = πr^2 h
⇝ 25,456 = π r^2 10
⇝r^2 = 25456 *7 / 22*10
⇝r^2 = 178192/220
⇝r = √809.9636
