Shelly runs 2.5 miles in 18 minutes. what is her mile time in minutes.​

Answers

Answer:

7.2315656

Step-by-step explanation:

Let's agree that 2.5 miles : 18 minutes is the ratio between the amount of distance and the amount of time spent running. If we spent 2x as many minutes running, Shelly would run 5 miles. In the same context, let's find the amount of distance covered in 18 minutes.

18 × (60/18) = 60

We multiply 60/18 because 60/18 = 60 × (1/18), and the (1/18) cancels with the 18 so we are left with the numerator, 60.

2.5 : 18

Now, we have to multiply 60/18 on both sides!

2.5 × (60/18) : 18 × (60/18) = 60

2.5 × (60/18) = 8 and 1/3 miles

The ideal length of a particular metal rod is 25.5 cm. The measured

range of acceptable lengths for the rod.

Answers

Answer:

Option: D is the correct answer.

D) 20.455 <= X <= 20.545

Step-by-step explanation:

We are given The ideal length of a particular metal rod is 20.5 cm.

It is given that:

The measured length may vary from the ideal length by at most 0.045 cm.

By atmost we mean either less than or equal to that amount but not more than that.

It means that:

|X-20.5|≤ 0.045

⇒  -0.045  ≤ X-20.5 ≤ 0.045

⇒    -0.045+20.5 ≤ X ≤ 20+0.045

⇒   20.455 ≤ X ≤ 20.545.

Answers

Answer:

7/4

Step-by-step explanation:

its 7/8 because if it goes down 1/8 each day count that for 2 weeks which is 14 days so it would be 14/8 or 7/4

HOPED THIS HELPED!!!!!!! :D

The total change in depth of the water during this time period is 7/4 in

What is subtraction?

To subtract means to take away from a group or a number of things.

Given that, the depth of water in a swimming pool decreases by 1/8 inch per day do to evaporation, no water is added to the pool for a two week.

The reduce in the pool in 1 day is 1/8 inch.

So, for 2 weeks, it's 14 days, therefore, in 14 days it will reduce = 1/8x14 = 7/4 in

Hence, The total change in depth of the water during this time period is 7/4 in

Sarah has $12.45 in quarters and nickels. She has 39 more nickels than quarters.

How many of each coin does she have?

Answers

Answer:

There are 14 nickes, 24 dimes and 48 quarters

Step-by-step explanation:

let x represent the number of nickels.

As she has 10 more dimes than nickels, the number of dimes is x + 10.

As she has twice as many quarters as dimes, the number of quarters is 2(x + 10)

the total value is $15.10, so I get an equation:

0.05x + 0.1*(x + 10) + 0.25*2(x + 10) = 15.10

0.05x + 0.1x + 1 + 0.5x + 5 = 15.10

0.65x = 9.1

x = 14

x + 10 = 24

2(x + 10) = 48

Answer:

  M = 141°, N = 39°

Step-by-step explanation:

Supplementary angles have a total measure of 180°, so ...

  M + N = 180

  (6x +3) +(2x -7) = 180

  8x = 184 . . . . . add 4, simplify
