Hi. Okay, #16 says write a decimal between 0.5 and 0.75. Then write it as a fraction in simplest form and as a percent.

write a decimal = I will pick 0.15 - now we need to write it as a fraction since the 5 is in the hundredths place our fractions would be:

15/100 = 3/20 (simplest form)

Now to change .15 to a percent we simply move the decimal two places to the right and add a % sign so. 15 = 15%

Question 17
How would you write 43 3/4% as a decimal

For this one, it is a lot easier than you think. The answer is 43.75. Let me tell you how...

To change 3/4 to a decimal, you are merely dividing the 4 into 3.00, hence the .75 and then just bring the 43 over. With problem like this that end in 1/4, 1/2, 3/4 just think of 4 quarters---1 quarter =.24, 2 quarters = .50, 3 quarters =.75

Question 16 answer is: .15, 15/100=3/20 and 15%
Question 17 answer is: 43.75

I hope this helps. If you have any questions, please don't hesitate to ask.

Take care,
Diana

A pair of basketball shoes was originally priced at $80, but was marked up 47.5%. What was the retail

Lelu [443]

47.5% in decimal form is 0.475.

Since the price was increased, we add 1 to 0.475 to get 1.475.

80 * 1.475 = 118

Another way to solve this is to multiply 80 by 0.475, which is 38, then add it to 80.

The retail price of the shoes is $118.

What is the value of a1 of the geometric series? Sigma-Summation Underscript n = 1 Overscript infinity EndScripts 12 (negative o

worty [1.4K]

Answer:

Step-by-step explanation:

The given geometric series is

$\sum_{n = 1}^{ \infty} 12( { - \frac{1}{9} })^{n - 1}$

We want to determine the first term of this geometric series.

Recall that the explicit formula is

$a_{n} = 12( { - \frac{1}{9} })^{n - 1}$

To find the first term, we put n=1 to get:

$a_{1} = 12( { - \frac{1}{9} })^{1 - 1}$

This gives us:

$a_{1} = 12( { - \frac{1}{9} })^{0}$

$a_{1} = 12(1) = 12$

Therefore the first term is 12

Jay places $3200 in an investment account earning 4.1% interest compounded weekly. How much money would he have in the account a

jasenka [17]

Answer:

A = $3,926.71

Step-by-step explanation:

Given: Principal (P) = $3200, Annual Rate (R) = 4.1%, Time = 5 years

To find: How much money would he have in the account after 5 years, if he made no deposits or withdrawals during that time?

Formula: $A = P(1 + r/n)^nt$

Solution: Compound interest is one of the most important concepts to understand when managing your finances. It can help you earn a higher return on your savings and investments, but it can also work against you when you're paying interest on a loan

First, convert R as a percent to r as a decimal

r = R/100

r = 4.1/100

r = 0.041 rate per year,

Then solve the equation for A

A = P(1 + r/n) $^{nt}$

A = 3,200.00(1 + 0.041/12) $^{(12)(5)}$

A = 3,200.00(1 + 0.003416667) $^{(60)}$

A = $3,926.71

Hence, Jay would have $3,926.71 after 5 years is if he made no deposits or withdrawals during that time.

A study is undertaken to find out how much water, in gallons, is in Lake Michigan. Which type of data will the study analyze?

Drupady [299]

<span>A.
continuous data
gallons in a lake would be continuous data because it is not counted in integers but measured by how much volume is in the lake.
