Easy! Just multiply 7 1/3 by 8 which leaves you with 58 2/3. Now, that 1/4 is 1/4 of an hour. If you can fill 7 1/3 boxes in 1 hour, how many can you fill in 1/4? 7 1/3 divided by 1/4 is 29 1/3. Add them together. 81 boxes.

We know that the true value for pi is given as 3.14156.

Now, we have been given that the approximate value for pi is 3.141

We know the formula

Absolute error,  \Delta x = | \text{True value } - \text{ Approximate value} | \\
\\
\Delta x =|3.14156-3.141|\\
\\
\Delta x =0.00056

Relative error is given by

\text{Relative error }= \frac{\Delta x}{\text{true value} }\\
\\
\text{Relative error }=\frac{0.00056}{3.14156} \\
\\
[tex]\text{Relative error }=0.000178

The percentage error is given by

\text{Relative error } \times 100\\  
\\  
0.000178\times 100  
\\  
=0.0178 \%

The greater of two numbers is one less than eight times the smaller . Their sum equals 98
Kitty [74]
B>a

b=8a-1

and we are told that 98=a+b so a=98-b, using this value for a in the equation above gives you:

b=8(98-b)-1

b=784-8b-1

b=783-8b

9b=783

b=87, and since a+b=98, a=11

so a and b are 11 and 87
