Answer:

60 inches

Step-by-step explanation:

In a rectangle, there are 2 pairs of congruent sides. Therefore, the perimeter of a rectangle can be found using:

p=l+l+w+w

We know that the length is 18 and the width is 12, so we can substitute 18 in for l, and 12 in for w.

p=18+18+12+12

Add all the numbers together

p=60

So, the perimeter is 60 inches

Of 375 musicians at a high school, some play only in the jazz band, some play only for the marching band, and some do both. If 2
Strike441 [17]
Let the number of musicians in the marching band be x, then
250 - 130 + 130 + x - 130 = 375
120 + x = 375
x = 375 - 120 = 255

Therefore, 255 musicians are in the matching band.

What is the answer. I’m so stuck and I don’t understand ¿?
DochEvi [55]
This is basically a physics problem that requires you to know v=s/t. The question asks for the velocity of each racer and you are provided with how many laps they made (s) and the time it took them (t). Therefore it is just a matter of you calculating these.
35/84= 0,416666666666667
42/96.6= 0,434782608695652
38/102.6= 0,37037037037037

Now because we used laps as the unit for s, DO NOT PUT ANY unit of measurement after it. This is just a good way of comparing one to another.

As you can see the fastest of them all should then be Evans.
