12. Since k is constant we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example if y varies directly as x, and y =6 when x=2, the constant of variation is k==3. The equation describing this direct variation is y=3x.
Answer:
272.97 m^2
Step-by-step explanation:
first find the area of the square
14*14
196
then find the area of the semicircle
A=πr^2/2
A=3.14*7^2/2
79.97
add the two areas together
196+79.97
272.97 m^2
Ok I’ll break this down so it’s easier to understand:
So you start of with $80
The first step is to find 20% off
An easy way to find 20% is to divide it by 5.
80/5= 16
And since it’s 20% OFF we subtract 16 from 80
80-16= 64
Next we need to do the coupon
It is $5 off so
64-5= 59
And finally the rebate which is $2
59-2= 57
