Answer: Circumference of Earth= 25120 miles
Step-by-step explanation:
Given: The circumference of a circle can be found using the formula , where d= diameter of the circle.
Earth's diameter = 8000 miles (approx)
The circumference of circle = [substitute values in formula]
The circumference of circle = 25120 miles (approx)
Hence, the circumference of Earth= 25120 miles (approx)
Answer:
(a) 0.4 or 40%
(b) 0.1 or 10%
Step-by-step explanation:
(a) If you get 4 "ones" after 10 rolls of the die, the proportion of the rolls that resulted in "ones" is:
(b) If you get 2 "ones" after 20 rolls of the die, the proportion of the rolls that resulted in "ones" is:
80/5=16
16*3=48
80-48=32
32\5=6.4
She spends $6.40 each day
Answer:
x=5 y=-1
Step-by-step explanation:
7x-2y=37
[2(4x+y=19)]=
8x+2y=38
---------------------
15x/15=75/15
x=5
[4(5)+y=19]
y=-1
52 and 54. Integers are whole numbers meaning 1..4..7..17...25 and so on. Consecutive meaning one right after the other. So 52 and 54 are the answer.
