First find the circumference of the circle.
Circumference:
Plug in 20 for the radius (r).
= 125.66
The circumference of the circle is 125.66 cm.
Now to find this in meters... there are 100 centimeters in 1 meter.
Divide 125.66 by 100 to find how many meters this is.
125.66 ÷ 100 = 1.26
The circle's circumference is 1.26 meters.
Th answer is 5 because 31% of 15 is 4.65
Answer:
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
P represents the principal or initial amount invested.
R represents the interest rate.
T represents duration of the investment in years
From the information given,
P = $750
R = 5%
T = y years
I = the total return of Bond 1 - principal
I = 1000 - 750 = $250
Therefore,
250 = (750 × 5 × y)/100
250 = 37.5y
y = 250/37.5
y = 6.7 years

Answer: -1.5/6 = -1/4; -1.7/9 = -17/90
Step-by-step explanation: Yeah, I'm not exactly sure what the problem is asking for, but this how I interpreted it. Use the LCD of the fractions -1.5/6 and -1.7/9 to find equivalent fractions with integer numerators and denominators.
For me, LCD doesn't help with solving the problem that much.
But anyways, the first fraction, -1.5, can be turned in an integer if you multiply the entire fraction by 2. So the result would be -3/12. You can simplify this to -1/4.
The second fraction, when multiplied by 10 yields -17/90. 17 is a prime number and is not a factor of 90, thus the equivalent fraction of -1.7/9 is 17/90.
Hope this helped.
