A new pair of shoes is advertised for $110. The sales tax is 7.5%. What is the total cost of the shoes?
Mashcka [7]

Answer:

118.25

Step-by-step explanation

If the tax is in percent, divide the tax rate by 100. You do this by moving the decimal point two spaces to the left. In this, there's 7.5/100 = 0.0

Find the tax value by multiplying tax rate by the item value:

tax = 110 × 0.075

tax = 8.25

What is the best approximate for the volume of cement used to make one of these spheres?
forsale [732]

Since we have that the volume of a sphere is given by:

V=\frac{3}{4}\pi r^3

And we have that the diameter equals 3.6ft, we then will have a volume of:

V=\frac{3}{4}\pi(1.8)^3\Rightarrow V\approx13.74

Since we have that the volume is approximately 13.74 ft^3, then the best approximation in the problem is A. 13.6 ft^3.

Pls i need help with #5 it’s so hard and I’m struggling with it and what’s the answer
Svetradugi [14.3K]

Answer:

7.5

Step-by-step explanation:

Lets define what we're looking for, the "number", to be equal to x.

number = x

Following the questions hints:

" The sum of twice a number and three times a number"

(2x) + (3x)

is (which means equals to basically)

" triple the quantity of five more than a number"

3(x+5)

We connect all of this to find the number and get:

(2x) + (3x) = 3(x+5)

5x = 3x + 15

5x -3x = 15

2x = 15

x = 15/2

x = 7.5
