Answer:
Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
We have the endpoints of the diameter of a circle (-8, -6) and (-4, -14).
The midpoint of a diameter is a center of a circle.
The formula of a midpoint:
Substitute:
We have h = -6 and k = -10.
The radius is the distance between a center and the point on a circumference of a circle.
The formula of a distance between two points:
Substitute (-6, -10) and (-8, -6):
Finally we have
Answer:
15%
Step-by-step explanation:
40=100%
20=50%
4=10%
2=5%
10%+5%=15%
4+2=6
Answer:
x=3
Step-by-step explanation:
-2x+3=x-6
-3x+3=-6
-3x=-9
-x=-3
x=3
Sum means the result of addition.
Quotient means the result of division.
Product means the result of multiplication.
The product of 3 and 7 is 21, because:
3 × 7 = 21
Therefore, the quotient is 21.
Let the sum of the facing page numbers = x:
Therefore, x/5 = 21
Rearranging the equation to find x (the sum of the facing page numbers) gives us:
x = 21 × 5
= 105
So the sum of the facing page numbers is 105.
The only two adjacent numbers which add up to 105 are 52 and 53, so the facing page numbers must be 52 and 53.
First, let’s find the distance Pam jogs in one hour.
15.75/3 = 5.25 mph.
Now, simply divide 28.875 (28 and decimal of 7/8) by our new rate.
28.875/5.25 = 5.5 hours. Choice B
