7,433,700 is the correct answer ;)
If 165 cm is 10% taller, then the equation we can use to find the original age is:
x×1.1=165
This means that to solve for x, we just need to divide by 1.1 on both sides of the equation:
x=150
Therefore, Cody was 150 cm tall last year
Answer:
31\frac{1}{2}ft^2
Step-by-step explanation:
From the information given each of the three rectangular countertops has dimension 4\frac{3}{8} by 2\frac{2}{5} feet.
The area of a rectangular shapes is the product of the dimensions.
Each rectangular countertop has area;
4\frac{3}{8}\times 2\frac{2}{5}=\frac{35}{8}\times \frac{12}{5} =10\frac{1}{2}ft^2
Therefore the number of square feet tiles needed to cover all the countertops is D.
