Answer:
5/2
Step-by-step explanation:
rise/run. the graph rises 5 and over 2 to the next point
Answer: f(x) = x/4
Steps:
f(x) = 4x
y = 4x
(Change x and y)
x = 4y
(Solve for y)
x/4 = y
(Change to f(x))
f(x) = x/4
42 received an A
so 40-42 = 38 did not
the fraction would be 38/80, divide both numbers by 2
38/80 reduces to 19/40 did not receive an A
Answer:
meter
Step-by-step explanation:
We have to write first what is known from the information.
Let's say, length is L, width is W, and height is H
1. The length of the box is 2 1/2 m = 2,5 m = 5/2 m, it is 1 9/16 = 25/16 times it's width (L). So we have the equation :
L ≡ 
Then we find the W. From the fraction above, we found W equals to
meter
2. What is the height of the box, if its volume is 12 3/4 m^3 = 51/4 m^3
Formula of a volume is :
The area wide times the height
In this problem, the equation is :
L × W × H = Volume
Insert the numbers,
×
× H = 
From the fraction above, we can find that H equals to
meter
