1 answer:

6 0

The correct answer is E (6 red, 4 yellow, 8 green, 6 blue, 12 white).

E) 6 + 4 + 8 + 6 + 12 = 36 (total marble count)
6 red/36 total marbles
simplify to find the probability ⬇️
(6/6=1; 36/6=6) = 1/6 chance of picking red

Rachel is making nachos for a party. The recipe calls for 2/3 cup of cheese for each plate of nachos. Part A: How many full plat

crimeas [40]

Part A:

We need to divide

5 ÷ 2/3

5/1 ÷ 2/3

5/1 * 3/2

15/2 or 7 1/2 plates of nachos.

Part B:

If Rachel can make 7 1/2 plates of nachos with 5 cups of cheese we need to multiply and subtract.

ma2/3 * 9 = 18/3 or 6 cups of cheese to make 9 plates

6 - 5 = 1 more cup of cheese she needs to make 9 plates

Best of Luck!

Answer:

$\large\boxed{y^{60}}$

Step-by-step explanation:

$(y^{-5})^{-10}y^{10}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\=y^{(-5)(-10)}y^{10}=y^{50}y^{10}\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=y^{50+10}=y^{60}$
