Answers

Answer 1
B) 6,839 cubic feet

Analiese,
The formula for volume of a cylinder is v=πr^2h
So first you plug in the info. you were given.
v=3.14x11^2x 18
Then, you simplify the equation.
v=3.14x121x18
v=3.14x2,178
v=6,839 cubic feet
Hope this helped

Answer:

8 : 20 and 24 : 60

Step-by-step explanation:

Given the ratio

[tex]\frac{2}{5}[/tex]

To obtain a ratio with 20 on the denominator multiply numerator and denominator by 4

= [tex]\frac{2(4)}{5(4)}[/tex] = [tex]\frac{8}{20}[/tex]

To obtain a ratio with 24 on the numerator multiply numerator and denominator by 12

= [tex]\frac{2(12)}{5(12)}[/tex] = [tex]\frac{24}{60}[/tex]

Winston has $20,000 in a savings account that earns 14% annually.The interest is not compounded.How much interest will he earn in 3 years? Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
NO LINKS

Answers

Answer:

I = $ 8,400.00

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 14%/100 = 0.14 per year,

then, solving our equation

I = 20000 × 0.14 × 3 = 8400

I = $ 8,400.00

The simple interest accumulated

on a principal of $ 20,000.00

at a rate of 14% per year

for 3 years is $ 8,400.00.

The expectation to play the game is $2.5 and the fair price to play is $7.5.

What is the expectation?

The expectation is defined as the weighted average value of the random variable which is the product of the value of the random variable and its possibility.

Expectation= ∑P(win)*amount of win or loss of random variable

=∑x*P(x)

Here given that there are only two possible outcomes $5 and $10. And the possibility of every outcome is the same which is 0.5 as they occupy the same area.

As we know

Expectation= ∑P(win)*amount of win or loss of random variable

= 0.5(5-5) +0.5(10-5)

=0.5*0 + 0.5*5

=0+2.5

=$2.5

As fair price= expectation + cost of play

⇒fair price= $2.5 + $5

⇒fair price= $7.5

Therefore the expectation to play the game is $2.5 and the fair price to play is $7.5.
