I is 100 cents equals to dollar
Hello from MrBillDoesMath!
Answer:
The last choice on the list, -z/y^7
Discussion:
-
(14x)^0 y^-7 z => m^0 = 1 if m <> 0
-1 * y^-7 z => y^-7 = 1/y^7
-z/y^7, which is the last choice on the list
Thank you,
MrB
To solve this problem, we have to set up a proportion, letting x represent the unknown height of the tree.
5 feet/8 feet = x feet/ 32 feet
To solve this equation, we have to use cross products, or the multiplication of the numerator of one fraction by the denominator of the other fraction, and setting them equal to one another.
5(32) = (8)x
When simplified, as we multiply the numbers on both sides of the equations, we get the equation:
160=8x
20=x
Therefore, if a tree's shadow is 32 feet long, the height of the tree is a) 20 feet.
Step-by-step explanation:
4. Let's multiply the coefficients. 2 * 6 * (-5) = -60. As for the exponents, since they have the same base we'll just add the exponents giving us s^(2 + 1 + 4) = s^7 so the answer is -60s^7.
7. -2/3 * -1/2 * -4 = -4/3 and the exponent is b^(2 + 3 + 4) = b^9 so the answer is -4/3b^9
You will have to have a equation to use substitution to find the answers
