Answer:
C. II only
Step-by-step explanation:
Basically all you need do is plug these answers in and if the complete the inequality to make a true statement.
Yes i know no body want to do that but that whats need to be done lol.
once i plug 7 12/7+8 = 12.83
12.83>20
is incorrect
so we need continue
7*2.5+8>20
7*2.5= 17.5
17.5+8= 25.5
25.5>20
this a true statement
so we know 2.5 is an answer
now we need plug in -3
7*-3= -21
-21 +8 = -13
-13>20
this is incorrect
Answer:
45.8 degrees
Step-by-step explanation:
We know that the temp before take off is 57.9
We also know the temp decreases every 1,000 feet so
if we are 11,000 feet in the air and divide that 11000/1000=11
We know that the temp drops 11 times
11x1.1=12.1
57.9-12.1=45.8 degrees
Group together common letters
4n+8n=12n
-3d+-3d=-6d
B.12n-6d
Answer:
13.76
Step-by-step explanation:
Area of the whole
The area of the whole = s^2 (the firgure is a square
s = 8
Area of the whole = 8^2 = 64
Area of the unshaded part
The 2 half circles = 1 whole circle
The radius of the 1/2 circle = 4 (eight has been cut in half)
Area of two half circles = 2* (pi r^2/2)
Area of two half circles = 2 * (pi 4^2/2)
area of two half circles = 16*pi
Area of the shaded area
Area of the shaded area = area of the whole - area of the unshaded area
Area of the shaded area = 64 - 16*pi
Area of the shaded area = 64 - 3.14*16 = 13.76
i think your answer is B. 27x
