Answer:
The answer is 30
Step-by-step explanation:
First you have to find 120% of a (12).

Therefore; 14.4 is 80% of b, and we are trying to find 100% of b

we do not know what is 100% therefore we call it *x*. In order to find this unknown value *x* we cross multiply.

This is the same as saying;

100% percent would be 1 because it is the whole number we are trying to find. The 80% would be 4/5. To get 4/5 you can simply break down 80/100 ( this is 80% as a fraction).
so the new equation is: 14.4= 4/5x
We divide both sides by 4/5. Then we will get x tobe equal to 18. Therefore b is 18. We were asked to find (a + b) so.<em> </em><em>1</em><em>8</em><em>+</em><em>1</em><em>2</em><em> </em><em>=</em><em> </em><em>30</em>
Answer:
B. 8 x 10^3
Step-by-step explanation:
1.6 x 10^5 / 0.2 x 10^2
= 160 000 / 20
= 8 000
You can write this as 8 x 10^3
