Answer:

  38.13 = 12 +4.75h

  5.5 hours

Step-by-step explanation:

(a) The charge (c) for renting a bike for h hours is ...

  c = helmet charge + hourly charge × hours

  c = 12.00 +4.75h

To find the number of hours when the charge is 38.13, we would use the equation ...

  38.13 = 12.00 +4.75h

__

(b) To solve this 2-step linear equation, we first subtract the constant

  26.13 = 4.75h

then we divide by the coefficient of the variable.

  26.13/4.75 = h ≈ 5.5

Amanda rented the bike for 5.5 hours.

_____

<em>Additional comment</em>

The result of the division is a long repeating decimal that starts off 5.50105263.... The instructions tell you to round this to the nearest tenth: 5.5. It helps to follow instructions.

I think it would just be 13 because T to U is 11 and U to V is 2 so if you want to find T to V you would add them together

Hope this helps in any way :))

Tyler's mom purchased a savings bond for Tyler. The value of the savings bond increases by 4% each year. One year after it was p
Gemiola [76]

Answer:

The value of the bond when Tyler's mom purchased it was $150

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

f(x)=a(b)^{x}

where

a is the initial value (y-intercept)

b is the base

r is the rate

b=(1+r)

In this problem

r=4%=4/100=0.04

b=1+0.04=1.04

substitute

f(x)=a(1.04)^{x}

where

x is the number of years since the savings bond was purchased

f(x) is the value of the savings bond

For x=1

f(x)=$156

substitute

156=a(1.04)^{1}

Solve for a

156=a(1.04)

a=\$150

therefore

The value of the bond when Tyler's mom purchased it was $150

Test 645 for divisibility by 2, 3, 5, 9, and 10.
zaharov [31]

Answer:To test for divisibility, you look for answers that are whole numbers when you divide 59859 by either 2, 3, 5, 9, or 10.

To start divide it by each of them:

59859/2=29929.5

59859/3= 19953

59859/5= 11971.8

59859/9= 6651

59859/10= 5985.9

Now look at which of the choices are whole numbers

3 and 9 are the only non decimal numbers, therefore, C would be your answer.

slamgirl [31]

Answer:

See explanation

Step-by-step explanation:

1. Determine the total distance heather has run in Km.

4.18km PER DAY for 197 days;  4.18 * 197 =  823.46km.

2. Can we just stop and say that this Heather chick MIGHT HAVE A PROBLEM?! Like, fr, she has run over 500 miles in half a year. . .she needs to see someone about that.

3. Divide the total distance by the distance of the track.

823.46/0.21 = 3921.23809524

4. Conclusion: Heather has run (roughly) 3,931.24 times around the track after the 197 day period of running 4.18km per day.
