208 ÷ 13 = 16, so her rate is $16 per hour. Through guess and check,
Kira would have to work 11 hours to make $176.
She typed 1.25 words per min
4/5 divided 8/7. You would do kcf or Kentucky chicken fried :) so you keep 4/5 multiply it by 7/8. Then multiply across and simplify. Hope this helps!!
The best and most correct answer among the choices provided by your question is the third choice or letter C "<span>commutative property of addition."
</span>The word "commutative" comes from "commute" or "move around", so theCommutative Property<span> is the one that refers to moving stuff around. For </span>addition<span>, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.</span>

Answer: 7
Step-by-step explanation:
Scientific notation is a method that is used in very large numbers or when we've very small numbers. The number given will be multiplied by its power of 10. In this case,
2.8 trillion = 2,800,000,000,000
= 2.8 × 10^12
0.4 trillion = 400,000,000,000
= 4 × 10^11
Therefore, the times more electricity was there in 1999 than 1950 will be:
= (2.8 × 10^12) / (4 × × 10^11)
= (2.8/4) / (10^12 - 11)
= 0.7 × 10
= 7 times
There were 7 times more electricity that was there in 1999 than 1950.
