Answer:
Step-by-step explanation:
This is a really famous diagram! The circle has been divided into many wedges (think slices of pizza!). The wedges have been colored alternately blue and yellow, then the wedges were rearranged to form a "rectangle" -- well, it's approximately a rectangle because the wedges have arcs (pieces of a circle) on them. See how the bottom and top edges of the rectangle look bumpy?
The area of the "rectangle" is approximately 
. The reason is that the height of the rectangle is <em>r</em> , the radius of the circle. And the length of the rectangle is about 
-- half the circumference of the circle. It's half because the circumference is in the bumpy parts of the wedges--half blue, half yellow.
The approximation improves as the number of wedges increases. In fact, as the number of slices (sorry, pizza again) gets larger, the length of the rectangle gets closer and closer to half the circumference. In other words, making more wedges makes the rectangle less bumpy!
Answer:
He needs 56c of lemon juice to make 4 salad dressings.
Step-by-step explanation:
We only need to look at how much lemon juice to make one salad dressing which would be 14c so we have to make 4 so we would do 14x4 to get how much lemon juice you need to make 4 dressings so you would need 56c of lemon juice to make 4 dressings

Answer:
After 4 months
Step-by-step explanation:
The cost at both the programs consists of a "fixed cost" (reg fee) & "variable cost" ( per month fee).
Let number of months be "x"
<u>Yo-Yoga:</u>
35 fixed
90 per month
So equation would be: 35 + 90x
<u>Essence Yoga:</u>
75 fixed
80 per month
So equation would be: 75 + 80x
To find number of month when cost would be same, we equate both equations and solve for x:
35 + 90x = 75 + 80x
10x = 40
x = 40/10
x = 4
hence, after 4 months, both cost would be same
