Answer: 62.8in
Step-by-step explanation:
The formula for circumference is C=2πr. Put the values of 10 in for r and 3.14 in for pi, and you get an equation that looks like C=2(3.14)(10). Solving this equation gets you 62.8.
Answer:
$6.88
Step-by-step explanation:
We are trying to compare two options: Buying a magazine for 12 months or for just 1 year.
To solve this, we can multiply the monthly rate by 12 because there are 12 months in a year.
5.99 x 12 = 71.88
The other option is to just pay $65 dollars for a whole year (12 months).
Comparing the two options, we see paying for the whole year is cheaper than paying for each month individually. Because of this, we can subtract $65, the cheaper option, from $71.88 to get $6.88
Chris will save $6.88 by paying for the whole year instead of purchasing for each month.
(3,6)(-2,1)
slope = (1 - 6) / (-2 - 3) = -5/-5 = 1
point slope form : y - y1 = m(x - x1)
slope(m) = 1
(3,6)....x1 = 3 and y1 = 6
now we sub
y - 6 = 1(x - 3) <===
Answer: B
Step-by-step explanation:
By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.
(2x+8)+(3x+5)=123 [combine like terms]
5x+13=123 [subtract both sides by 13]
5x=110 [divide both sides by 5]
x=22
Now, we know that the answer is B.
