what is the height of a trapezoid with one base equal to 20m, the other base equal to 7m, and an area of 135m^2

german

Answer:

<h2>The height is 10 m</h2>

Step-by-step explanation:

Area of a trapezoid is given by

where

a and b are the bases

h is the height

From the question

A = 135 m²

a = 20m

b = 7 m

Substitute the values into the above formula and solve for the height

That's

<h3> $135 = \frac{1}{2} (20 + 7)h \\ 135 = \frac{1}{2} \times 27h \\ 135 \times 2 = 2 \times \frac{1}{2} \times 27h \\ 270 = 27h$ </h3>

<u>Divide both sides by 27</u>

That's

We have the final answer as

Hope this helps you

Probably simple math. 20 points.

Harlamova29_29 [7]

ok well first you would find what the square root would be then you just see where it falls on the number line

so the sqrt of 29 is 5.38516... so it falls between 5 and 6.

so the answer is 5 and 6

If the odd against the occurence of an event be 4:7 find the proabilty of the occurence of the event.

Alla [95]

Answer:

$Probability = \frac{7}{11}$

Step-by-step explanation:

Given

$Odds:Occurence = 4:7$

Required

Determine the probability of the occurrence

First, we need to get the total of the ratio

$Total = 4 + 7$

$Total = 11$

Next, is to calculate the required probability as follows;

$Probability = \frac{Occurrence}{Total}$

$Probability = \frac{7}{11}$

<em>Hence, the required probability is </em>

$Probability = \frac{7}{11}$
