Answer:

8763

Step-by-step explanation:

Let x represent the number of students the college had last year. Then this year's enrollment is ...

... x - 3%·x = 8500

... x(1 - 0.03) = 8500 . . . . . collect terms

... x = 8500/0.97 ≈ 8762.89 . . . . divide by the coefficient of x

Enrollment last year was about 8763.

_____

Of course, you know 3% = 3/100 = 0.03.

Cerrena [4.2K]

Answer:

<u><em>x=9</em></u>.

<em><u>perimeter=68</u></em>

<em><u>area=168</u></em>

Step-by-step explanation:

First find the side that has a exact number which would be the bottom 28cm then look at the opposite side (2x+10) in order to find x subtract 10 from 28 which gives you 18, now 2x means x multiplied by 2 so what multiplied by 2 = 18? 9 meaning <u><em>x=9</em></u>. Now you are going to want to plug 9 in to your short side (x-3) once you plug it in it should look like this 9-3 and 9-3=6 meaning the short side is 6cm. In order for you to find the perimeter you have to add the sides together so 28+28+6+6 wich <u><em>=68</em></u> and in order for you to find the area you have to  multiply the length and the width so 28x6 which is <em><u>168</u></em>.

hope that helped :)

MATH QUESTION!! PLEASE HELP
svlad2 [7]

bro i literally had the same question about this

you in honors or something? sry i only got A

I might have B later on or something

Answer:

A.

41.125π ≈ 129

149.875π ≈ 471

Step-by-step explanation:

Surface area of smaller ganza:

3.5/2 = 1.75 x 1.75 = 3.0625 x 3.14 = 9.61625 x 2 = 19.2325

1.75 x 10 = 17.5 x 3.14 = 54.95 x 2 = 109.9 + 19.2 = 129 (Rounded)

Surface area of larger ganza:

5.5/2=2.75 x 2.75 = 7.5625 x 3.14 = 23.74625 x 2 = 47.4925

2.75 x 24.5 = 67.375 x 3.14 = 211.5575 x 2 = 423.115 + 47.4925 = 471 (Rounded)

π

129/3.14 = 41.125

471/3.14 = 149.875
