Answer:
The perimeter of a circle is π × d. Here's is the diameter of the circle. Hence, the perimeter of a circle is half of that of the circle that is ½ π × d.
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
Step-by-step explanation:
Answer:
It is 2.
Step-by-step explanation:
The equation becomes -2y=-4x=5
But you divide by -2 to get y solo. So -4/-2=2.
Answer: 2526 dollars
=============================
Work Shown:
Plug n = 400,000 into the function and simplify
f(n) = 939 + 5.29*(n-100,000)/(1,000)
f(400,000) = 939 + 5.29*(400,000-100,000)/(1,000)
f(400,000) = 939 + 5.29*(300,000)/(1,000)
f(400,000) = 939 + 5.29*(300)
f(400,000) = 939 + 1,587
f(400,000) = 2526
Using it's concept, the probabilities are given as follows:
a) C. 7/20.
b) D. 15/22.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
For item a, we have that there are 60 students with no curfew, and of those, 21 have no chores, hence the probability is given by:
p = 21/60 = 7/20
Which means that option C is correct.
For item b, we have that there are 66 students with no shores, and of those, 45 have a curfew, hence the probability is given by:
p = 45/66 = 15/22
Which means that option D is correct.

Answer:
7.5
Step-by-step explanation:
8x÷4=12÷4
2x=3
x=3/2=1.5
2y+10=22
2y=12
y=6
1.5+6=7.5=7½
