Ratios are like fractions. 5:6 is the same as 5/6.
Answer:
Cost of Material per square foot = $1.7
Step-by-step explanation:
Given:
Length = 24
Width = 12
Height = 6.5
Find:
Cost of Material per square foot
Computation:
TSA of pit = 2[bh + hl] + lb
TSA of pit = 2[(12)(6.5) + (24)(6.5)] + (24)(12)
TSA of pit = 2[78+156] + 288
TSA of pit = 756 square foot
Cost of Material per square foot = 1,285.20 / 756
Cost of Material per square foot = $1.7
$18.72
Because 4.50 + 4% is 4.68 then times 4 is 18.72
Y=k/x is inverse
y=2
x=8
2=k/8
times 8
16=k
the equation is
y=16/x
second
y=k/x
-3=k/1
-3=k
the equation is y=-3/x
they are
for y=2, x=8 it is y=16/x
and for y-3, x=1 it is y=-3/x
