1 answer:

5 0

11/10 is closer because the bigger the denamorator is the smaller the pieces are, and 10 is bigger than 8 also 11/10 might be over 1 but it is still closer.

Find the radius of the sphere with a volume of 32/81π cubic yards. Write your answer as a fraction in simplest form. PLEASE HELP

NeTakaya

Area of a sphere = 4(pi)(r)^2
Reverse the equation to find the radius (r)
The answer will be in pi form

32/81(pi)

8/20.25(pi)

Square root of 8/20.25(pi) = radius

r = 2.8(rounded)/4.5(pi)

The store bought the bike at a wholesale price. The bike store marked up the wholesale cost of the bike by 60%. What was the who

marin [14]

Answer: The wholesale cost of the bike = $100

Step-by-step explanation:

Let x = wholesale cost of the bike

As per given,

Selling price = cost price + (Mark up percent) x ( cost price) (i)

Selling price of bike = $160

Mark up percent = 60% =0.60

Substitute values in (i) , we get

$160= x+0.6x\\\\\Rightarrow\ 160=1.6x\\\\\Rightarrow\ x=\dfrac{160}{1.6}\\\\\Rightarrow\ x= 100$

Hence, the wholesale cost of the bike = $100

After eating at your favorite restaurant, you know that the bill before tax is $52.60 and that the sales tax rate is 8 percent.

lisov135 [29]

Answer:

Tip = $10.52

Tax = $4.21

Total bill = $67.33

Step-by-step explanation:

We are given the following in the question:

Pre-tax bill = $52.60

Tip to waiter = 20% of the pre-tax amount

Tip to waiter =

$20\%\times \text{Pre-tax amount}\\\\=\dfrac{20}{100}\times 52.60\\\\=10.52$

Thus, $10.52 was given to waiter.

Tax on bill = 8% of the pre-tax amount

Tax =

$8\%\times \text{Pre-tax amount}\\\\=\dfrac{8}{100}\times 52.60\\\\=4.21$

Thus, tax on bill was $4.21.

Total bill =

Pre-tax amount + Tax + Tip

$=52.60 + 4.21 + 10.52\\=67.33\$$

Thus, the total bill is $67.33
