Sean read 15 of a book in 112 hours.

1 answer:

8 0

Sean read 15 of a book in = 112 hours,
so, 1 of a book in = 112/15

Now, 12 of a book would be: 112/15 * 12 = 112/5 * 4 = 89.6

89.6 = 89 6/10 = 89 3/5

In short, Your Answer would be 89 3/5 hours

Hope this helps!

Hi!

First, find the total percent of vehicles with at least 3 people.

15% + 7% + 3% = 25%

Now find 25% of 420

Set up a proportion and cross multiply to solve.

$\frac{x}{420} \frac{25}{100}$

25 * 420 = 10500

10500/100 = 105

The answer is 105 vehicles contained at least 3 people.

Hope this helped! :)

Answer: OPTION D

Step-by-step explanation:

The formula for calculate the surface area of a rectangular prism is:

$SA_{rp}=2(wh+lw+lh)$

Where w is the width, h is the height and l is the length.

You can see in the figure attached that:

l=3.4ft

w=3ft

h=4.1ft

Therefore, when you substitute these values into the formula you obtain that the surface area is:

$SA_{rp}=2[(3ft*4.1ft)+(3.4ft*3ft)+(3.4ft*4.1ft)]=72.88ft^{2}$

Shani borrowed $5000 at an annual interest rate of 4% compounded yearly. William borrowed the same amount of money at an annual

Natalka [10]

Answer: William will pay $ 330.76 more interest than Shani at the end of 3 years.

Step-by-step explanation:

Compound interest = $P((1+r)^t-1)$ <em> , </em>P= principal , r= rate of interest , t= time

Given: P = $5000 , t= 3 years

For Shani , r= 4% = 0.04

Compound interest = $5000((1+0.04)^3-1)$

$=5000(1.124864-1)\\\\=5000(0.124864)\\\\=\$\ 624.32$

For William, r= 6%= 0.06

Compound interest = $5000((1+0.06)^3-1)$

$=5000(1.191016-1)\\\\=5000(0.191016)\\\\=\$\ 955.08$

Difference = $ ( 955.08- 624.32)

= $ 330.76

Hence, William will pay $ 330.76 more interest than Shani at the end of 3 years.
