Answer:
22
Step-by-step explanation:
-7 is < than 6 so we use the top equation
(-3 multiplied by -7) +1
21+1
22 is the answer
7.58 x 10^-3 is the scientific notation
<h3>
Answer: x*a^2 or a^2*x</h3>
======================================
Work Shown:
a^(b+2) = a^b*a^2 ... break up the exponent
a^(b+2) = x*a^2 ... replace a^b with x
We don't know the value of 'a' nor the value of x, so we cannot evaluate further. This is the same as a^2*x because order of multiplication does not matter. For example, 2*3 = 6 and 3*2 = 6, so 2*3 = 3*2.
Answer: 24% of all employees attend night school.
Step-by-step explanation: If 40% of all employees are men and 30% of the men attend night school, we can multiply 0.40 by 0.30 to get the percentage of men who attend night school: 12% or 0.12. To find the number of women who attend night school, multiply 0.20 by 0.60(assuming percentage of men and women add up to 100%) to get 12%. Add 12% and 12% to get 24% of all employees attend night school.
