Corresponding sides of the two triangles occur in a ratio with one another. In particular, you have the relationship
We only need the first two parts to solve for 
:
To find a percent of a number, multiply the percent by the number.
First we find the number of pennies.
40% of 220 =
= 40% * 220
= 0.4 * 220
= 88
88 coins are pennies.
220 - 88 = 132
132 coins are not pennies.
Now we find 25% of 132.
25% of 132 =
= 25% * 132
= 0.25 * 132
= 33
33 coins are partners.
(Did you mean quarters instead of partners?)
Answer:
-57
Step-by-step explanation:
Put the value of x where x is and do the arithmetic.
-7·9 +6 = -63 +6 = -57
Radius is exactly half of diameter.
