To find the circumference of a circle you use the formula, C=2*pi*radius or C=pi*diameter, in his case you would use the first option, C=2*pi*radius, because the radius is the given value. You then plug the values into the equation to solve for the circumference...
C=2*pi*15
C=30*pi
C=30pi or approximately 94.2478
66,098 rounded to the nearest ten thousands place is 70,000.
I'm going to have to go with choice "c". 10x - 1 with the remainder of 5
Answer:
A heart will beat 140 times in 2 minutes
Step-by-step explanation:
700 ÷ 10 = 70
140 ÷ 70 = 2
Rate of burn(scented):1/8inch in 1/4h
=4(1/8)inch in 1h=1/2inch in 1h
Rate of burn(unscented):1/9inch in 1/3h=3(1/9)inch in 1h=1/3inch in 1h
The scented candle burns more in one hour.
1/2inch-1/3inch=1/6inch
The scented candle burns 1/6inch more per hour
