Find the area of the trapezoid.

Usimov [2.4K]

Answer:

$\large\boxed{A=54\ m^2}$

Step-by-step explanation:

The formula of an area of a trapezoid:

$A=\dfrac{b_1+b_2}{2}\cdor h$

<em>b₁, b₂</em> - <em>bases</em>

<em>h</em><em> - height</em>

We must use the Pythagorean theorem:

$x^2+8^2=10^2$

$x^2+64=100$ <em>subtract 64 from both sides</em>

$x^2=36\to x=\sqrt{36}\\\\x=6\ m$

We have <em>b₁ = 6 + 6 = 12m</em>, <em>b₂ = 6m</em> and <em>h = 8m</em>.

Substitute:

$A=\dfrac{12+6}{2}\cdot6=\dfrac{18}{2}\cdot6=(9)(6)=54\ m^2$

Elena-2011 [213]

Answer:

11/23 or 0.478

Step-by-step explanation:

1. Find the probability of selecting 2 red chips:

11/23 * 10/22 = 5/23

2. Find the probability of selecting 2 blue chips:

12/23 * 11/22 = 6/23

3. Add the two probabilities:

5/23 + 6/23 = 11/23 = 0.478 (rounded to 3 decimal places)

Can anyone help me on what’s -4 - (-3) plsss it’s for my math test

ololo11 [35]

Answer:

-1

Step-by-step explanation:

It is negative 1 because the signs for the -3 are the same so you keep the -4, change the - to a +, then flip the negative 3.

Hope this helps!
