Step-by-step explanation:
let eqn be y = mx + b.
m = 80/10 = 8
sub (0, 0):
0 = 8(0) + b
b = 0
therefore equation is y = 8x

See diagram
look a right triangle
for a right triangle
with legs legnth a and b and hypotonuse c
a²+b²=c²
so
the legs are 7 and the diagonal is c
a=b since all 4 sides of a square are equal legnth
7²+7²=c²
49+49=c²
98=c²
sqrt both sides
√98=c
(√49)(√2)=c
(7)(√2)=c
7√2=c
the legnth of the diagonal is 7√2 inches or aprox 9.899 inches
V = 30*16*12. To find the volume of a rectangular prism, you just multiply the area of the base (side 1 * side 2) by the height of the prism.
1/5 (0.2)
0.49
