Answer:

Paralellogram's area would be A = bh (or base times height)
Rectangle or square would be A = lw (length times width)
Triangle would be A = 1/2 bh (basically divide the base x height by 2)
Trapezoid would be A = 1/2 (a+b)h (or for me I do base 1 which is a and base 2 which is b times height and then divide by 2 or division then multiplication first)

Step-by-step explanation:

I hopes this helped :)

In a certain four-engine vintage aircraft, now quite unreliable, each engine has a 15% chance of failure on any flight, as

Romashka [77]

Answer:

0.0975 or 9.75%

Step-by-step explanation:

Assuming that no engines fail simultaneously, the probability that exactly one engine fails is the probability that the first engine fails (15%) multiplied by the probability that the second engine does not fail (100% - 35%):

$P = 0.15*(1-0.35)\\P=0.0975$

The probability of exactly one engine failure is 0.0975 or 9.75%

Given isosceles trapezoid TRHY, in units what is the length of b2 if the height is 13 units, b1 is 21 units, and the area is 215

GenaCL600 [577]

We are given a trapezoid TRHY.

Height of the trapezoid = 13 units.

b1 = 21 units and

Area = 215 units squares.

We need to find the length of b2.

We know formula for area of a trapezoid.

$A= \frac{1}{2} (b1+b2)\times h$

Plugging values in formula.

215 = $\frac{1}{2}$ (21+b2)× 13.

215 = 6.5(21+b2)

Dividing both sides by 6.5, we get

$\frac{215}{6.5}=\frac{6.5(21+b2)}{6.5}$

33.08 = 21+b2.

Subtracting 21 from both sides, we get

33.08-21 = 21-21+b2

b2 = 12.08.

<h3>Therefore, length of b2 is 12.08 units.</h3>

What is the solution to equation 8-2x+6=24

ki77a [65]

8 - 2x + 6 = 24

(8 + 6) - 2x = 24

14 - 2x = 24 <em>subtract 14 from both sides</em>

-2x = 10 <em>divide both sides by (-2)</em>
