Answer:
4096.
Step-by-step explanation:
We have been given that Dave wants to buy a new collar for each of his 4 cats. The collars come in a choice of 8 different colors. We are asked to find the number of selections of collars for the 4 cats if repetitions of colors are allowed.
Since repetitions are allowed, so collars for each cat be chosen in 8 different ways.
Total number of selections would be 
Therefore, there are 4096 possible selections of collars.
Answer:
5 x 4 = 20, 20 x 1/2 (basically just dividing by 2) = 10
10 x 3(width) = 30 inches is your answer.
Answer
He needs to buy 27 Cows
Step-by-step explanation:
if the ratio from horses to cows is 5-3 then you multiply 5 by the number to get 45 and also multiply it by 3
5 x <u>9</u> = 45
3 x <u>9</u> = 27
-72 = 14/3(41) + b
-72 = 574/3 + b
-72 - 574/3 = b
-216/3 - 574/3 = b
- 790/3 = b
First you need to distribute the exponent into the terms for the first parenthesis.
(-3x²y³)³ = (-3)³ * (x²)³ * (y³)³
= -27 *x⁶ *y⁹
= -27x⁶y⁹
Then you multiply -27x⁶y⁹ by x²y.
You just need to add the exponents of x and y:
-27x⁶⁺²y⁹⁺¹
= -27x⁸y¹⁰
