If a = 12 and 120% of a is equal to 80\% of bthen what is a + b ?
Novosadov [1.4K]

Answer:

The answer is 30

Step-by-step explanation:

First you have to find 120% of a (12).

\frac{12}{1}  \times  \frac{120}{100}  = 14.4

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

14.4 = 80\% \\ x = 100\%

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

14.4 \times 100\% = 80\% \times x

This is the same as saying;

14.4  \times 1 = x \times  \frac{4}{5}

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>

*PLEASE HELP MEEEEEE* You throw a dart at the board shown. Your dart is equally likely to hit any point inside the square board.
yawa3891 [41]

Answer:

19.63%

Step-by-step explanation:

The probability of scoring 8 points is the probability of getting a dart into the green circle.

That probability is equivalent to the area of the circle divided by the total area of the square board.

The area of the circle according to A=\pi*r^2, is 25\pi cm squared

The area of the whole square board is one side squared: 20 squared = 400 cm squared

The probability is therefore equal to 25\pi/400 = \pi/16=0.19634=19.63%%
