Hopes this can help
Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality.

Shelly is trying to improve her running time for a track race. She ran the first race in 43.13 seconds. Her time was 43.1 second

saul85 [17]

<h3>The time in fourth race is 43.04 seconds</h3>

Solution:

Given that,

Shelly is trying to improve her running time for a track race

She ran the first race in 43.13 seconds

Her time was 43.1 seconds in the second race and 43.07 seconds in the third race

Therefore, pattern is:

43.13, 43.1, 43.07 , ..

Find the difference between each terms

d = 43.13 - 43.1 = 0.03

d = 43.1 - 43.07 = 0.03

Thus the difference is same

If this pattern continues what will shellys time be in the fourth race?

Fourth race = third race - 0.03

Fourth race = 43.07 - 0.03 = 43.04

Thus the time in fourth race is 43.04 seconds

What is 360 to 30 in ratio

Pepsi [2]

360 to 30 can be written as 360:30 and call also be written as 360/30

$\frac{360}{30} = \frac{36 \times 10}{3 \times 10}= \frac{36}{3} = \frac{12 \times 3}{1 \times 3} = \frac{12}{1}$

360 to 30 simplified can be expressed as a ratio like 12:1, 12 to 1, or 12/1

A train leaves Roseville heading east at 6:00 am at 40 miles per hour. Another eastbound train leaves on a parallel track at 7:0

Molodets [167]

Answer:

At 11:00 am the both trains will be at same distance away from Roseville

Step-by-step explanation:

The first train was 40 miles away from Roseville at 7:00 am

After some time t the both trains will be at the same distance away from Roseville.

We will make equation for that situation

d- distance v1= 40mph and v2= 50mph - velocity

d = v1*t + 40 = v2*t => v2*t - v1*t = 40 => t (v2-v1) = 40 -> t = 40/ (v2-v1)

t = 40/(50-40) = 40/10= 4h t = 4h

7:00 am * 4h = 11:00 am

Good luck!!!

James and Cameron are watching a film. They pause it with one fifth left to watch. What is the ratio of how much they have watch

goldenfox [79]

Answer:

The ratio of how much they have watched to how much they have left to see is 4 : 1.

Step-by-step explanation:

Consider that the total duration of the film is, 1.

It is provided that James and Cameron paused when there is one-fifth left to watch.

That is, they have already watched, $1-\frac{1}{5}=\frac{4}{5}$ th of the film.

Compute the ratio of how much they have watched to how much they have left to see as follows:

$\frac{\text{Duration Watched}}{\text{Duration Left}}=\frac{4/5}{1/5}=\frac{4}{1}=4:1$

Thus, the ratio of how much they have watched to how much they have left to see is 4 : 1.
