Answer:

Step-by-step explanation:

circumference=πd=π×18=18π in

distance covered in 1 sec=18π×10=180π in.

distance covered in 1 min=180π×60=10800π in

distance covered in 60 min=10800π×60=648000π in=648000π÷12=54000π ft

=54000π÷3=18000π yards=18000π÷1760≈32.13 miles per hour.

What's the correct choice please help
nadezda [96]

Answer:

$77,886

Step-by-step explanation:

We solve this question by proportions, using a rule of three.

The table states that:

$201.6 in 2006 is worth $232.957 in 2013.

We want to find:

The value of $90,000 in 2013 in 2006:

$201.6 - $232.957

x - $90000

Applying cross multiplication

232957x = 201.6*90000

x = \frac{201.6*90000}{232957}

x = 77886

$77,886 is the answer

What should be the first step in solving 13 y − 14 = 42?
AveGali [126]

Answer:

The first step should be adding 14 to both sides of the equation.

Step-by-step explanation:

14 must be added on both sides of the equation to get 13y by itself. The ultimate goal is to get y by itself if we are solving for y.

Once 14 is added on both sides, you'll get:

13y = 56.

Then 13 would be divided from both sides.

y = 4.3
