Answer:
0.7778
Step-by-step explanation:
step 1
Address the input parameters and observe what to be found:
Input values:
The fraction = 21/27
What to be found:
Find the decimal expansion of fraction 21/27.
step 2
The numerator is smaller than the denominator of the fraction 21/27, so find how many 10s should be multiplied with both numerator and denominator. Since the number of digits are equal in both numerator and denominator, multiply 10 with both numerator and denominator of 21/27.

step 5
Repeat the step 2 to find the decimal equivalent for the fraction 21/27 in the above expression:
= (7 + 21
27
) x 1
10
= (7 + 0.778) x1
10
step 6
Simplify the above expression further:
= (7 + 0.778) x1
10
= 7.778 x1
10
=7.778

= 0.7778
Hence,
21/27 as a decimal is 0.7778
V(1)=65t+280 answer 65 gallons per minute
As you look at the picture above, you may notice that the WV
is half of TV.
To solve for the equation above,
You need to learn first that the TV will be WV (2), because
WV is only half of the TV, giving two WV.
After that, you have to write your equation.
Since we need two WV = (4x + 1) + (4x + 1) = 74(TV)
Simplify both WV, will give you = 8x + 2(WV) = 74(TV)
In order to get the x, subtract 2 from 74, finally giving
you 8x=72
Divide 8 and 72, in order to obtain your x.
The answer is: X=9

Just add 25 minutes. That's because they boarded at 3:55 and took 25 minutes to just go to the fair. So in 25 more minutes they got to the fair! so it would be 4:20 when they got to the fair.
