Martin runs 100 meters in 15 seconds. What is the equation for d, the distance in meters that Martin covers per second?

Marizza181 [45]

The answer is d x 15 =100

In order to get the value of d, you must transpose the constant 15 to the left side of the equation.

It can also be written like this:

15d = 100

Divide both sides by 15:

15d / 15 =100/15

d = 6.667 meters per second

Antonette gets $70\%$ on a 10-problem test, $80\%$ on a 20-problem test and $90\%$ on a 30-problem test. If the three tests are

notka56 [123]

Answer:

Percentage score will be 83.33 %

Step-by-step explanation:

We have given Antonette gets 70 % on 10 problem test

Let consider here here total problem = total marks

So marks get 10 10 problem test = 10×0.7 = 7

Marks get in 20 problem test = 20×0.8 = 16

And marks get in 30 problem test = 30×0.9 = 27

Now total marks get get by Antonette = 7 +16 + 27 = 50

And total marks = 60

So percentage score of Antonette $=\frac{50}{60}\times 100=83.33$ %
