A person invests $1000 in a bank. The bank pays 6% interest compounded monthly. To the nearest tenth of a year, how long must th

liraira [26]

Answer:

18 years, 4 months and 10 days.

Step-by-step explanation:

Given that the person invests $ 1000 in an account with compound interest each month, with an interest rate of 6%, to determine how long the investment must maintain to reach $ 3,000, the following calculation must be performed:

3,000 = 1,000 (1 + 0.06 / 12) ^ Yx12

3,000 = 1,000 (1 + 0.06 / 12) ^ 18.36x12

3,000 = 3,000

Therefore, the person must keep his investment for a period of 18.36 years. Since 12 x 0.36 is equal to 4.32, the total investment time should be 18 years, 4 months and 10 days.

If a wheel with a radius of 50 inches spins at a rate of 500 revolutions per minute, find the approximate linear velocity in mil

Artyom0805 [142]

Answer:

The linear velocity in miles per our is 14789400 mph .

Step-by-step explanation:

Given as :

The radius of wheel = 50 inches

So, the diameter of wheel = 2 × radius = 2×50 = 100 inches

Or, Diameter = 100 × 1.57 miles = 157 miles

The number of revolution per minutes = 500 RPM

or, The number of revolution per hours = 500 × 60 = 30,000 RPH

Now, Circumference of wheel = $\pi$ ×diameter

Or, C = 3.14 × 157 = 492.98 miles

So, Distance cover by wheel = C × RPH × Time in hour

or, D = 492.98 × 30,000 × Time in hour

And Velocity = $\dfrac{\textrm Distance in miles }{\textrm Time in hour}$

or, V = $\dfrac{\textrm 492.98 × 30,000 × Time in hour }{\textrm Time in hour}$

or, V = 14789400 miles per hour

Hence The linear velocity in miles per our is 14789400 mph . Answer

Rachel budgeted $76.50 for school clothes. This is 0.45 of her total budget. How much does Rachel have her total budget?

balu736 [363]

Let her total budget = x

0.45 x = 76.5 Divide by 0.45

0.45 x / 0.45 = 76.5 / 0.45

x = 170 dollars. I'm using a calculator. Are you allowed to do that?

Johnathan went shopping at HEB. He began to look at two different cereals below Sunshine Cornflakes: 24-ounce box for $4.32 Brig

mel-nik [20]

Answer:

Step-by-step explanation:

Given that:

Johnathan looked at two different portions of cereals at the supermarket.

They are:

Sunshine Cornflakes: 24-ounce box for $4.32

Bright Start Cornflakes: 36-ounce box for $5.76

To calculate the cost of one ounce of Sunshine cornflakes, we have:

24-ounce box for $4.32

1 - ounce box will be x

x = ($4.32 × 1 ounce box) / 24 ounce box

x = $0.18

1 - ounce box will be = $0.18

To calculate the cost of one ounce of Bright star cornflakes, we have:

36-ounce box for $5.76

1 - ounce box will be = ( $5.76 × 1 ounce box) / 36 ounce box

1 - ounce box will be = $0.16

Since 1 - ounce box of Bright star cornflakes is lesser than 1 - ounce box of Sunshine Cornflakes.

Then, Bright star cornflakes costs ($0.18 - $0.16) = $0.02 per ounce box lesser than Sunshine Cornflakes.

Thus, Bright star cornflakes will be a better buy.
