Answer:
1. Option D.
2. Option A.
Step-by-step explanation:
1. You need to follow these steps in order to estimate the sum of :
Step 1: Add the digits in the ones places of the whole numbers (these are: 8, 9 and 5).
Step 2: Round the decimals to the nearest whole number:
Step 3: Add them together:
2. The procedure to estimate the difference of is:
Rounded to the nearest whole number:
2(x-5) + 4x - 7 = 7
2x-10 + 4x -7 -7 =0
6x - 24 = 0
6x = 24
x= 24/6
x= 4
Micah's answer is incorrect because X=4
Answer: 0.25

Work Shown:
A = student selected is an eighth grader
B = chosen student takes bus
P(A) = probability of selecting eighth grader
P(A and B) = probability of selecting eighth grader AND student who takes bus
P(A and B) = probability of selecting eighth grader who takes the bus
P(B|A) = probability of selecting someone who takes the bus given they are an eighth grader
P(B|A) = [P(A and B)]/[P(A)]
P(B|A) = 0.11/0.44
P(B|A) = 0.25
40 miles
If he goes 20 miles in every hour, then in two hours he will travel 20 + 20 miles.
Circumference of a circle is pi x diameter (full length of the circle)
you have the radius which is half, so youd need to double it go geth the diameter.
24x2=48
and then 3.14x48=150.72
