36 because 90 -45%= 54
90-54= 46
Answer:
first one is the right answer
Answer:
½ = x
Step-by-step explanation:
As discussed in one of my You-Tube videos on Exponential Rules, aᵐ\ⁿ, any base to the half power is the SAME AS taking the exponential denominator of that power, and setting that to the square root of the base, leaving the exponential numerator on the outside:
25¹\² = √25
25 = a [Base]
1 = m [Exponential Numerator]
2 = n [Exponential Denominator]
As you can see, it is unnecessary to put the two because by definition, any vacant root is automatically assumed as the square root, and 1, which is the exponential numerator, is on the outside, which again is unnecessary because 5¹ is 5.

7w = 24 - 3
7w = 21
w = 21 ÷ 7 = 3
35 shirts/ 50 shirts* 100%
= 0.7* 100%
= 70%
70% of 50 shirts is 35 shirts~
