a trapezoid has an area of 50 square inches. The bases are 3 inches and 7 inches. What is the height of the trapezoid.
charle [14.2K]

Answer: The answer is 10 inches.

Step-by-step explanation:  Given that the area of a trapezoid is 50 square inches and the bases are 3 inches and 7 inches. We are to find the height of the trapezoid.

We know that the area of a trapezoid with height 'h' and bases 'a' inches and 'b' inches is given by

A=\dfrac{a+b}{2}h.

In the given question,

a = 3 inches, b = 7 inches, A = 50 square inches, h = ?

Therefore,

50=\dfrac{3+7}{2}\times h\\\\\\\Rightarrow 50=5h\\\\\Rightarrow h=10.

Thus, the required height is 10 inches.

Find the distance<br> (-2, 1) and (4,3)
natima [27]

Answer:

2\sqrt{10} units

Step-by-step explanation:

The distance formula states that D(x_{1} ,y_{1})(x_{2},y_{2} )=\sqrt{(x_{2} } -x_{1} )^2+(y_{2}-y_{1}  )^2\\.

We then plug in our points and compute.\sqrt{(4-(-2))^2+(3-1)^2} =\sqrt{6^2+2^2} =\sqrt{36+4} =\sqrt{40} =\sqrt{2^2*2*5} =2*\sqrt{2*5} =2\sqrt{10}

The * represents multiplication.
