Answer:
a) 
b) She needs 5 consecutive free throws in order to raise her percent to
85 %
Step-by-step explanation:
We know that a basketball player made 12 out of 15 free throws she attempted.
We can calculate its percent of successful free throws as :

%
Now, If she wants to know how many consecutive free throws she would have to make to raise the percent of successful free throws to 85 % we can write :
(I)
In the equation (I) ''n'' represents the number of consecutive free throws she must have to raise the percent to 85 %.
We answer
a) 
b) Now we need to solve the equation (I) :
⇒
⇒
⇒
⇒ 
We found out that she needs 5 consecutive free throws to raise the percent of successful free throws to 85 %.
We can verify by replacing the value of ''n'' in the equation (I) ⇒
⇒
⇒
Answer:
10a^2b^2
Step-by-step explanation:
Formula = 1/2(b)(h)
h = 4a
b = 5ab^2
4a(5ab^2) = 20a^2b^2/2 = 10a^2b^2
Answer:
38.5
Step-by-step explanation:
Use the trapezoid area formula which is (a+b)h/2. We know that a=6, b=8 and h=5.5. Plugging it it to the formula, we get (6+8)*5.5/2 which is 38.5.
