Answer:
x = 9
Step-by-step explanation:
Both the triangles are similar, so the corresponding sides are also similar.
That is,
12 / 8 = x / 6
Cross multiply,
x * 8 = 12 * 6
8x = 72
Divide 8 on both sides,
x = 72 / 8
x = 9
Answer:
He needs 7 more consecutive successful first serves to raise his first serve percentage to 60%.
Step-by-step explanation:
After n consecutive serves, his total number of serves is going to be n+8, since he has already served 8 times. In the best case, his number of successful first serves is n+2.
His percentage of succesful first serves is the division of the number of succesful first serves divided by the total number of serves. So

We want
. So







He needs 7 more consecutive successful first serves to raise his first serve percentage to 60%.
Answer:
$7.5
Step-by-step explanation:
1 quart = 4 cups
So:
12 cups = 12/4 = 3 quarts
Each quart is 2.5 dollars
3 * 2.5 = $7.5
Answer:
c
Step-by-step explanation:
Using the Altitude- on- Hypotenuse theorem
( leg of the large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
x² = 3 × ( 3 + 8) = 3 × 11 = 33 ( take the square root of both sides )
x =
→ c
