Step-by-step explanation:
12/4=3 and 16/8=2
She would need 480 minutes of sleep. Do 8 x 6 and add a 0
The shaded region is actually a sector and the formula for the area of a sector is:
central angle/360 x pi x radius squared, which is basically a fraction of the area of the circle. With this basic background knowledge, all we have to do is substitute the values into the formula.
(80/36) x pi x 81
= 80/4 x pi x 9
= 720/4 x pi
= 180pi cm squared.
Let the two numbers be x and y.
According to your question;
x + y = 7
10y + x = 10x + y + 9
By equation 1 ; x = 7-y
Substituting the value of x ;
10y + ( 7 -y) = 10(7-y) + y + 9
9y + 7 = 70 -10y + y + 9
9y + 7 = 70 - 9y + 9
=> 18y = 70 -7 + 9
=> 18y = 72
=> y = 4
Substituting for x ;
x = 7 - y
=> x = 7 -4
=> x = 3
Thus, x = 3 and y = 4;
=> The number is 34.
The answer is he will make $300 commission for 25 TV sets sold. The first thing you need to do is find out how much commission he makes on each TV. So we take $120 and divide by 10% and that gives us $12. So $12 is the amount of commission per TV. Then we just need to multiply the $12 by 25 TV sets. That gives us the answer of $300 commission total.
A second way to solve this problem is by taking the $120 and multiplying that by the 25 TV sets. That gives you $3,000 total for the 25 TV sets. Then you just divide the 10% commission Mike will make. That also gives you the answer of $300 commission.
