First we have to find the find the distance for single revolution.
Distance= 2πr
Put values
Distance= 2(3.14)(13)
Distance=81.64 inches in a single revolution.
Now in 30 revolution, distance= 30 x 81.64
Distance=2449.2 inches,

How long does it take $500 to double at a simple interest rate of 24%?

yuradex [85]

Answer:

4 years and 2 months

Step-by-step explanation:

<u>Simple interest formula</u>

A = P(1 + rt)

where:

A = final amount
P = principal amount
r = interest rate (in decimal form)
t = time (in years)

Given:

A = $500 × 2 = $1,000
P = $500
r = 24% = 0.24

Substitute the given values into the formula and solve for t:

$\implies \sf 1000 = 500(1 + 0.24t)$

$\implies \sf \dfrac{1000}{500}=(1 + 0.24t)$

$\implies \sf 2=1 + 0.24t$

$\implies \sf 1 = 0.24t$

$\implies \sf t=\dfrac{1}{0.24}$

$\implies \sf t=4 \frac{1}{6} \:years$

$\implies \sf t=4\:years\:2\:months$

Therefore, it takes 4 years and 2 months for the initial investment of $500 to double at a simple interested rate of 24%.

Write the pair of fractions as a pair of fractions with a common denominator 2/4 and 7/8

jeka94

The answer would be 4/8 and 7/8
You get this by find 4x2 will have a product of 8, so multiply 2/4 by 8/8 to create the equivalent fraction.

Can anyone help me please and explain this: Write "60 pounds for $6.60" as a unit rate per ounce to the nearest tenth. 1 pound=

VMariaS [17]

If the rate is 60 pounds for $6.60 and we need to convert it to a unit rate per ounce, you will think of it as $6.60 for 60 pounds instead.

Divide to get a unit rate per pound.

$0.11 per pound

To convert this to an amount per ounce Change the rate to say $0.11 per 16 ounces(this means the same).

Divide 0.11 by 16 to get 0.006875 or $0.007 or 0.7 cents per ounce. Choice D but it should say per ounce, not per pound.
