Answer:
y = x
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the given condition that y = 7 when x = 42
k = = =
y = x ← equation of variation
Answer:
By an online search, I've found that the dimensions of the eraser are:
4cm by 2cm by 0.5cm
First, we need to remember that for a rectangular prism of length L, width W, and height H, the volume is:
V = L*W*H
We know that the measures of the box are:
12cm by 20cm by 5cm
Then we can define:
L = 12cm
W = 20cm
H = 5cm
Then the total volume of the box is:
V = 12cm*20cm*5cm = 1200 cm^3
For the eraser, we will have:
L = 4cm
W = 2cm
H = 0.5cm
Then the volume of the eraser is:
v = 4cm*2cm*0.5cm = 4 cm^3
The volume of the box that is not taken up by the eraser is equal to the difference between the volume of the box and the volume of the eraser.
Then:
Volume not taken by the eraser = V - v = 1200cm^3 - 4cm^3 = 1196cm^3
0.375
= 375 /1000. Cancel out using 25
= 15 / 40 Cancel out using 5
= 3 / 8
