C. 7.5 inches
You can write the dimensions of the room as 10:15
and the dimensions of the drawing as
5: (unknown).
Divide the original dimensions by 2 to get the unknown value.
10: 15 ÷ 2 = 5: 7.5
So, when the width is 5in, the length is 7.5in.
The circumference is (2 pi) (radius) . The ratio of radius to circumference is (1)/(2 pi).
Student c was close to average
Simplify the following:
8 p^3 - 3 p^3 - 2 p^2 + 5 p - 12 p - 4 + 5
Grouping like terms, 8 p^3 - 3 p^3 - 2 p^2 + 5 p - 12 p - 4 + 5 = (-3 p^3 + 8 p^3) - 2 p^2 + (5 p - 12 p) + (-4 + 5):
(-3 p^3 + 8 p^3) - 2 p^2 + (5 p - 12 p) + (-4 + 5)
8 p^3 - 3 p^3 = 5 p^3:
5 p^3 - 2 p^2 + (5 p - 12 p) + (-4 + 5)
5 p - 12 p = -7 p:
5 p^3 - 2 p^2 + -7 p + (-4 + 5)
5 - 4 = 1:
Answer: 5 p^3 - 2 p^2 - 7 p + 1
Answer:
5x - 8 < 37 and x < 9
Step-by-step explanation:
again, sorry if it's wrong.
5x - 8 < 37
+8 +8
5x < 45
