Answer:

16.1 MPH

Step-by-step explanation:

If the wheels have a radius of 15 inches, then the circumference of a wheel is 2πr = 2 * π * 15 ≈  94.248 inches.

If the wheels turn at 3 revolutions per second, that mean the car is travelling 94.248 * 3 ≈ 282.74 inches/second.

There are 12*5280 = 63360 inches in a mile and 60 * 60 = 3600 seconds in an hour. So to convert from inches/second to miles per hour, we need to divide the inches per second figure by (63360/3600), which is 17.6, to get miles per hour (MPH).

So in this case, 282.74/17.6 gives you approximately 16.1 MPH.

If a person wants to have $2000 after 4 years, how much would they have to deposit into an account that pays 6.5% interest compo
V125BC [204]

Answer:

The amount is $2572.93 and the interest is $572.93.

Step-by-step explanation:

STEP 1: To find amount we use formula:

A=P(1+rn)n⋅t

A = total amount  

P = principal or amount of money deposited,

r = annual interest rate  

n = number of times compounded per year

t = time in years

In this example we have

P=$2000 , r=6.5% , n=1 and t=4 years

After plugging the given information we have

AAAA=2000(1+0.0651)1⋅4=2000⋅1.0654=2000⋅1.286466=2572.93

STEP 2: To find interest we use formula A=P+I, since A=2572.93 and P = 2000 we have:

A2572.93II=P+I=2000+I=2572.93−2000=572.93

What is the simplified form of the quantity 12 z-squared plus 25z plus 12 over the quantity 3 z-squared minus 2z minus 8 ?
Vinvika [58]
(12z^2 + 25z + 12)/(3z^2 - 2z - 8) You have to factor it. You know how to factor it right? (12z^2 + 16z + 9z + 12)/(3z^2 - 6z + 4z - 8) (4z(3z + 4) + 3(3z + 4))/(3z(z - 2) + 4(z - 2)) ((4z + 3)(3z + 4))/((3z + 4)(z - 2)) (4z + 3)/(z - 2)

What ratios are equivalent to 10:16? What Apply
ASHA 777 [7]

Answer:

The answer is option 1 and 3.

Step-by-step explanation:

Firstly, you have to find the simplest form of the ratio by dividing the common numbers :

10:16 =  \frac{10}{16}  =  \frac{5 \times 2}{8}  =  \frac{5}{8}

Given that the simplest ratio is 5:8. Next, you have to simplify all the options given and which is equivalent to 5:8 :

Option 1,

30 \: to \: 48 = 30:48 =  \frac{30}{48}  =  \frac{5 \times 6}{8 \times 6}  = \frac{5}{8}  = 5:8 \: (correct)

Option 2,

25:35 =  \frac{25}{35}  =  \frac{5 \times 5}{7 \times 5}  =  \frac{5}{7}  = 5:7 \: (incorrect)

Option 3,

\frac{40}{64}  =  \frac{5 \times 8}{8 \times 8}  =  \frac{5}{8}  = 5:8 \: (correct)

Option 4,

8:32 =  \frac{8}{32}  =  \frac{1 \times 8}{4 \times 8}  =  \frac{1}{4}  = 1:4\:  (incorrect)

Option 5,

5 \: to \: 15 =  \frac{5}{15}  =  \frac{1 \times 5}{3 \times 5}  =  \frac{1}{3}  = 1:3 \: (incorrect)
