A trapezoid has an area of 42 square miles. One base is 4 miles long. The height measures 6 miles. What is the length of the oth

loris [4]

The length of other base of trapezoid is 10 miles

Step-by-step explanation:

The formula for area of trapezoid is:

$A=\frac{h}{2}(b_1+b_2)$

We know that

A = 42 square miles

b_1 = 4 miles

h = 6 miles

Putting the values

$42=\frac{6}{2}(4+b_2)\\42=3(4+b_2)\\42=12+3b_2\\Subtracting\ 12\ from\ both\ sides\\42-12=12+3b_2-12\\3b_2=30\\Dividing\ both\ sides\ by\ 3\\\frac{3b_2}{3}=\frac{30}{3}\\b_2=10\ miles$

The length of other base of trapezoid is 10 miles

Keisha is working on a math worksheet with 50 problems. She has completed 20 problems in 25 minutes. If she continues at the sam

Sidana [21]

Set up a proportion.

$\sf\dfrac{20}{25}=\dfrac{50}{x}$

Cross multiply:

$\sf1250=20x$

Divide 20 to both sides:

$\sf~x=62.5$

So it will take 62.5 minutes for her to complete the worksheet.
