2+1=3 is not an identity property. The rest are because the value equals itself after dividing, subtracting, and multiplying.
Percent change (increase or decrease) is the amount of change over the original amount. So (5-2/5)=3/5 or 60% decrease in the number of cheese sticks you can buy for $1
Answer:
B | 6
Step-by-step explanation:
First, find the length of the wire by finding the perimeter of the rectangle
2(5) 2(7) = 24
If a square has 4 sides, put 24 as the numerator and 4 as the denominator.
24/4
Now, divide it and you'll get 6, the answer.
Answer:
Midpoint =1.5,1
radius 4.71699
C = 29.623
A =69.865
Step-by-step explanation:
To find the midpoint, add the endpoint coordinates together and divide by 2
M = (x1+x2)/2, (y1+y2)/2
= (-1+4)/2, (5+-3)/2
= 3/2 , 2/2
=1.5,1
Once we know the midpoint, we can find the radius from one endpoint to the midpoint
d = sqrt( (x2-x1)^2+ (y2-y1)^2)
sqrt( (1.5--1)^2+ (1-5)^2)
sqrt(( 1.5+1)^2 + (4)^2)
sqrt( 2.5^2 +16)
sqrt(6.25 +16)
sqrt(22.25)
4.71699
The circumference is given by
C = 2*pi*r
= 2* (3.14) * 4.717
= 29.623
The area of a circle is given by
A = pi r^2
= 3.14 * 4.717^2
=69.865
