Take 37% as an example, just add a decimal point to the left 2 times. Decimal = .37. Fraction would be 37/100, because you cannot simplify.
Answer:
80
Step-by-step explanation:

Answers</h3><h3>diameter = 14</h3><h3>radius = 7</h3><h3>area = 154</h3>
these are all approximate
======================================
Explanation:
C = pi*d is the formula for the circumference. We know that C = 44 approximately, so,
C = pi*d
d = C/pi
d = 44/3.14
d = 14.01 approximately
d = 14 also approximate
take half of this to get the radius
r = d/2 = 14/2 = 7
Then use this radius to find the circle's area
A = pi*r^2
A = 3.14*7^2
A = 153.86
A = 154 rounding to the nearest whole number
The 6 in the hundreds place tells you the quotient is at least 100. The non-zero digits in the 1s and 10s places tell you the quotient is more than 100.
Answer: 187.7 mph
Step-by-step explanation:
v = 125 mph
t = 1.2 min
v2 = ?
t2 = 0.8 min
We can use the rule of 3 here. It's the inverse rule of 3 because as time decreases, speed increases.
