Answer:
B
Step-by-step explanation:
The number of ways to choose a combination of 7 objects from a group of 15 objects is 15! / (7! 8!)
(3<span> x $9) + (</span>3<span> x </span>$1<span>) = $27 + $3 = </span>$30<span>.</span>
So,
The skateboard cost $67.
The protective helmet cost $25.
To find the percent that the price of the skateboard was out of the total amount, add 67 and 25 and divide 67 by the result.
Step 1:
67 + 25 = 92
Step 2:
67/92 = 0.728 or 72.8%.
The correct option is B.
Answer:
x^1/8 y^8
Step-by-step explanation:
= x^(1/4 * 1/2) y^(16 * 1/2) =
Multiplicative inverse of 1/2 = 2/1 = 2
Thus, the multiplicative inverse of 1/2 is 2.
