For 31 you need 6% OF 50 meaning you need to multiply. 50*0.06=3. The answer for 31 is 3.
To find 33 you need to divide 1 by 0.4 to find how much you need to multiply 28 by. 1/0.4= 2.5 then you need to do 2.5*28 which would equal 70. The answer for 33 is 70.
To find 35 you need to notice that it DECREASES in meaning the bigger number (20) would be the denominator of the fraction and 15 would be the numerator. Therefore the fraction would b 15/20 or 75% of 20 would equal out to 15.
I believe the answer is $17500

is a right triangle with base length 1 and height 8, so the area of

is

.
The average value of

over

is given by the ratio

The denominator is just the area of

, which we already know. The average value is then simplified to

In the

-plane, we can describe the region

as all points

that lie between the lines

and

(the lines which coincide with the triangle's base and hypotenuse, respectively), taking

. So, the integral is given by, and evaluates to,



Answer:
Total donation by Alonzo's mother = $40.
Step-by-step explanation:
Complete Question.
Alonzo will participate in a charity walkathon.Her Mother will donate $10 for Alonzo participation plus and additional $2 for each mile that Alonzo walks.
If Alonzo walks 15 miles, What will be the amount of her mother’s donation?
Alonzo's mum donates $10 for participation and an additional $2 per mile.
Alonzo walks 15 miles, this translates to an additional donation of (15×$2) = $30
Total donation by Alonzo's mother = $10 + $30 = $40.
Hope this Helps!!!
