I believe the answer would be b. I think this is because you know that the perimeter is the length times 2 and the width times 2 added together. If you do 12 times 2 you get 24. Then you subtract this from 56 because 56 is the perimeter of the whole thing. Then after this you get 32.Then divide 32 by 2 to find ONE of the widths.

Gonna do a little subbing here...

for 40 pgs of express proof reading....3 bucks per pg...c = 3
40(3) - 0.05(40(3)) = T
120 - 0.05(120) = T.....120 - 6 = T.....114 = T
so  express proofreading cost 114

for 40 pgs of basic proof reading....c = 3.95
40(3.95) - 0.05(40(3.95) = T
158 - 0.05(158) = T....158 - 7.9 = T.....150.10
so basic proof reading costs 150.10

for 40 pgs of extended proof reading....c = 5
40(5) - 0.05(40(5) = T
200 - 0.05(200) = T....200 - 10 = 190
so extended proof reading is 190

no need to go further....the extended proof reading is gonna be ur answer...the best quality of editing that keeps it at 190

So far this basketball season, Sherita made 46 of her
Tresset [83]

Answer:

<em>Sherita would need to make 10 free throws</em>

Step-by-step explanation:

<u>Proportions</u>

Sherita made 46 of her first 60 free throws in this basketball season. Calculating the average we get:

\displaystyle \frac{46}{60}=76.7\%

Sherita wants to have a free throw average of at least 80% in her next x free throws. This means she will have 46+x made throws out of 60+x total throws. For this new performance, the new average would be:

\displaystyle \frac{46+x}{60+x}

And we equate it to 80% (0.8 in decimal):

\displaystyle \frac{46+x}{60+x}=0.8

Multiplying by 60+x:

46+x=0.8(60+x)

Operating:

46+x=48+0.8x

Subtracting 46 and 0.8x:

0.2x=2

Dividing by 0.2

x = 10

Sherita would need to make 10 free throws

Will someone, please help solve this equation?​
kipiarov [429]

Answer:

131.25

Step-by-step explanation:

There are 3 trapezoids that you need to find its area, all the areas are the same.

Area of trapezoid:

A=(a+b)/2*h

a = 20

b = 15

h = (20-15)/2 = 5/2

A = (20+15)/2*5/2

A = 43.75

3A (3 gardens) = 131.25
