Teds minimum grade he needs on his third test is 65
85 + 60 + 65 = 210
210 divide by three (as there are three tests) = 70
First, let's calculate the area of the rectangle. Find the distances between the length and the width. For the width we can use point A and point D.
(2, 2) and (20, 2)
20 - 2 = 18
So the width is 18 cm. Now find the length. We can use point A and point B.
(2, 2) and 2, 26)
26 - 2 = 24
So the length is 24.
So the area of the rectangle is 432 square centimeters, now let's find the area of the circle.
The radius is given as 15 cm. Use 3.14 to approximate for pi.
So the area of the circle is approximately 706.5 square centimeters. Subtract this area from the area of the rectangle to find the value of the shaded area.
Answer:
(3x-6)/x^2+5x-14
Step-by-step explanation:
No matter who long or complicated the denominators are, if they are the same, it is OK to just add the numerators together and keep the denominator the same.
13x+4y=487------>13x+4y=487----------->13x+4y=487
6x+2y=232-------->-2(6x+2y)=232*-2---->-12x-4y=-464
x=23----> 6(23)+2y=232------->138+2y=232----->2y=94--->y=47
x=ties y=suspenders
200,000 tons. There are 2000 lbs in a ton so do 4,000,000,000 divided by 2000 and you get 200,000
