What is the area of this trapezoid? Enter your answer in the box.​
mezya [45]

Answer:

352 ft²

Step-by-step explanation:

The formula for the area of a trapezoid is A=(\frac{b_1+b_2}{2})h where b_1 and b_2 are the bases of the trapezoid and h is the height, thus:

A=(\frac{b_1+b_2}{2})h\\\\A=(\frac{13+31}{2})(16)\\\\A=(\frac{44}{2})(16)\\ \\A=(22)(16)\\\\A=352

This means that the area of the trapezoid is 352 ft².

Simplify by dividing negative three over eight divided by five over nine..
IRISSAK [1]

Answer:

-15/24 or -0.625

Step-by-step explanation:

-3/8 ÷ 5/9

First, we can use the multiplication fraction conversion trick to switch the last fraction's numerator and denominator

It would look like this: -3/8 x 9/5

Use the cross out method to simplify the fractions as lowest as possible

-1/8 x 3/5 = -15/24

On the coordinate plane below, Point P is located at (2,-3), and point Q is located at (-4,4).
nadezda [96]

Answer:

9

Step-by-step explanation:

We can use the distance formula

d = sqrt (   ( y2-y1)^2 + ( x2-x1) ^2)

d = sqrt (   ( 4- -3)^2 + ( -4 -2) ^2)

   = sqrt (  ( 7^2  + ( -6)^2)

   = sqrt( 49+ 36)

   = sqrt(85)

      9.219544457

Rounding to the nearest whole number

 = 9
