Find the height of a trapezoid given that it has an area of 650
square feet and the lengths of its bases are 23 feet and 42 feet.

h = 20ft

Step-by-step explanation:

A = a+b/2 x h

Use the formula by substituting in the known measurements.

650 = 23 + 42 / 2 x h

Add the bases together. (23 + 42 = 65)

Divide by 2. (65/2 = 32.5)

Next, divide the area by the bases. (650/32.5 = 20)

There's your answer. The height is 20ft.

Remember, to check all you have to do is plug the numbers back into the formula.

(23 + 42 / 2 x 20 = ?) We already did the steps for the bases so all you have to do is multiply 32.5 by 20, which gives you 650.

Hope this helps.

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
