Answer:
8
Step-by-step explanation:
10d - 22 + 6d = 12d + 10
16d - 22 = 12d +10
4d = 32
d = 8
It takes 4 3/8 hours if you travel at an average speed of 80km/hr
Circumference of a circle is 2πr where r is radius of a circle.
2*3.14*7=43.96 almost 44 inches in whole number where π=3.14
Answer:
2 11/15
Step-by-step explanation:
Let X equal the decimal number
Equation 1:
X=2.73¯¯¯(1)
With 1 digits in the repeating decimal group,
create a second equation by multiplying
both sides by 101 = 10
Equation 2:
10X=27.33¯¯¯(2)
Subtract equation (1) from equation (2)
10XX9X===27.33...2.73...24.6
We get
9X=24.6
Solve for X
X=24.69
Multiply to eliminate 1 decimal places.
Here you multiply top and bottom by 1 10's
= 101 = 10
24.69×1010=24690
Find the Greatest Common Factor (GCF) of 246 and 90, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 6,
246÷690÷6=4115
Simplify the improper fraction,
=21115
In conclusion,
2.73¯¯¯=2 11/15
