Answer:

A = (1/2)(7 units)(5 units) = (35/2) units^2.

Step-by-step explanation:

Call AB "the base" and recognize that its length is 7 units. Call BC "the height" and recognize that its length is 5 units.

Then apply the area-of-a-triangle formula A = (1/2)(base)(height):

A = (1/2)(7 units)(5 units) = (35/2) units^2.

$\large \mathfrak{Solution : }$

let's solve for x :

$\dfrac{2}{9} x - \dfrac{1}{3} = - 1$

$\dfrac{2}{9} x = - 1 + \dfrac{1}{3}$

$\dfrac{2}{9} x = \dfrac{ - 3 + 1}{3}$

$x = \dfrac{ - 2}{3} \times \dfrac{9}{2}$

$x = - 3$

I hope it helped...

Girls: median= 33, mean=34

Step-by-step explanation:

Mean is the average. Median is the middle number. Both groups had 10 scores. Boys ranged from 15-81. Girls from 0-75; their mean & median would be less because their scores are less.

What irrational number can be added to pi to get a sum that is rational

m_a_m_a [10]

Answer is -pi

Let x be this unknown number. Adding on x to pi gets us the expression x+pi

If we set x+pi equal to zero (which is a rational number) and solve for x, we get

x+pi = 0

x+pi - pi = 0 - pi

x = -pi

so adding pi to -pi will lead to 0 since

x+pi = -pi+pi = 0
