Answer:

1.6 miles

Step-by-step explanation:

Example 1

It took Markus half an hour to drive home from work.  He averaged 34 miles per hour.  How far does Markus live from his work?

Solution

We are given that it takes 1/2 an hour for the trip.  This is a time:

       t  =  1/2

We are given that he averages 34 miles per hour.  This is a rate:

       r  =  34

We are asked how few he has traveled.  This is a distance.  We use the d=rt equation:

       d  =  rt  

           =  (34)(1/2)

           =  17

Markus lives 17 miles from work.

Now try one by yourself.  If you want to see the answer, put your mouse on the yellow rectangle and the answer will appear.

Exercise 1

A piece of cable 8.5 cm long weighs 52 grams. How much does a cable that is 10 cm long weigh
Arturiano [62]
8.5 cm cable weighs = 52 grams

1 cm of cable weighs = \frac{52}{8.5}grams
                                      
                                      = 52/ \frac{85}{10} grams
                                      = 52* \frac{10}{85} grams
                                      = \frac{520}{85} grams
                                      = 6.11764 grams
Rounding it up = 6. 10000 grams

Then, 

10 cm of cable weighs = 6.10*10 grams
                                            <span>    </span>= 61.0 grams

What is the value of h? g = -7.1 h = 3 - 10g
Step2247 [10]

Answer:

74

Step-by-step explanation:

Please separate the two functions:

g = -7.1

h = 3 - 10g

Substitute -7.1 for g in h = 3 - 10g:

h = 3 - 10(-7.1) = 71 + 3 = 74

find the measure of the arc or angle indicated. assume that lines which appear tangent are tangent
Serjik [45]

Answer:

Option (1)

Step-by-step explanation:

By the property of alternate segment theorem,

"Angle formed between the tangent and the chord in a circle measures the half of the measure of the intercepted arc"

m(∠EFG) = \frac{1}{2} × m(minor arc FG)

minor arc FG = 2m(∠EFG)

                      = 2(76°)

                      = 152°

Therefore, Option (1) will be the correct option.
