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 small airplane can fly 12 miles in 3 minutes. At this rate, how far can it fly in 7 minutes? In an hour?
Kay [80]

Answer:

28 miles in 7 minutes, 240 miles in an hour

Step-by-step explanation:

We can first simplify the rate to miles per minute. Since the plane goes 12 miles in 3 minutes, we can divide it by 3 to find how much it travels in one minute. 12 divided by 3 is 4 and 3 divided by 3 is 1

The plane travels 4 miles a minute

To find how much it travels in 7 minutes, multiply by 7

4x7 is 28

28 miles in 7 minutes

To find an hour, multiply by 60

4x60= 240

240 miles in an hour

Supposed charity received a donation of $23.9 million. If this represents 54% of the charity donated funds what is the total amo
Tanzania [10]

Total amount of funds is $44.26 million.

Step-by-step explanation:

Given,

Donation received = $23.9 million

As it represents 54% of charity.

Let,

Total amount = x

Therefore,

54% of x = 23.9 million

\frac{54}{100}*x=23.9\\0.54x=23.9

Dividing both sides by 0.54

\frac{0.54x}{0.54}=\frac{23.9}{0.54}\\x=\$44.26\ millions

Total amount of funds is $44.26 million.

Problem: 80% of 385

Step 1 You will be Multiplying

Step 2. Move the decimal to the left by 2 places.

Example: 385

              x .80

              ----------

Step 3 do the problem

example:  385

                 x.80

               -----------

               308.0% is the percentage

               make sure to drop the decimal  but if there  there nothing after it don't leave it in your final answers ( some teachers mark it wrong when it really it's not wrong just improper format)

Find the mean of the integers: 7,-9,9,-7,0
Aleks04 [339]

Step-by-step explanation:

Add all of the numbers together

7 + 9 + 0 + (-9) + (-7)

simplify it down to:

(7+9+0)= 16

-9 + (-7)= - 16

So, -16 + 16 = 0

then divide 0 by 5 to get the answer of 0

To find the mean you have to add all of the numbers together and then divide by the amount of numbers that you have.
