First, let's create an equation for this problem.
($70 × 4) + $40
Now, all you would have to do is solve it using the order of operation (PEMDAS).
($70 × 4) + $40 = $280 + $40
$280 + $40 = $320
The plumber charged $320.
I hope this helps!
Answer:
Train A is 287 tons
Train B is 94 tons
Step-by-step explanation:
My method of solving it may have been a bit different from how you were taught. I divided 381 by 2 to give both trains an equal weight of 190.5 tons. I then divided the difference, 193, by 2 to get 96.5 tons. I subtracted the new difference from the weight of Train B and added it to train A. To double check, you can grab a calculator and see that their weights are equal to 381.
(8+15+8+3+12)/2+1=24th number will be median
So median is gonna be 21
To find the length of the base using the information given, you will use the formula for finding the area of a parallelogram and solve for the missing base.
A =bh
<u>160.5</u> = <u>7.5b</u>
7.5 7.5
b = 21.4 inches
The length of the base is 21.4 inches.
2 divided by 18 will equal 9
so just multiply that by the minutes (3)
9×3=27 minutes
