Answer:
150+55w
Step-by-step explanation:
150 never changes
(55)(w), 55 changes depending on number of weeks
The expression is: 150 + 55W
amount already in your a/c = $150
Amount saved per week = $55
Number of weeks to save for is W
Amount saved in W weeks is $55W
Total amount saved in W weeks is $150 + $55W
Ignoring the symbols, the expression is 150+55W
b
i think that because it has most biggest number it is smaller than 1/4
the density of the iron is 7.9 g /cm^3
The computation of the density of the iron is shown below:
Density = weight ÷ volume
= 474 ÷ (5 × 3 × 4)
= 474 ÷ 60
= 7.9 g /cm^3
Hence, the density of the iron is 7.9 g /cm^3
112 ft
9) Here, we are finding the area of a triangle. The equation for area is:
Where A is area, b is the base, and h is height.
Step one;
given
initial weight = 55 pounds
final weight= 45 pounds
Step two:
Required
the % weight decrease
% decrease= initial-final/initial *100
% decrease= 55-45/55 *100
% decrease= 10/55 *100
% decrease= 0.18 *100
% decrease= 18%
