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

Help please ! solve for x and round the answer to the nearest tenth. need it asap , thank you

Jlenok [28]

Answer:

5.2

Step-by-step explanation:

$\frac{17}{13} = \frac{x}{4}$

To solve for x, we want to isolate x. To do this, we need to multiply both sides by 4.

$(\frac{4}{1})(\frac{17}{13}) = x$

Multiply the numerators and the denominators separately.

4 • 17 = 68

1 • 13 = 13

$\frac{68}{13} = x$

Divide.

68 ÷ 13 = 5.23

Round to the nearest tenth.

5.2

Hope this helps!

Step-by-step explanation:

20 women's shoes are athletic.

35 women's shoes are formal.

52 women's shoes are casual.

The total number of women's shoes is 107. So the probability that a randomly selected one is casual is:

P = 52/107

P ≈ 48.6%
