7. The points P(2, -3), Q(3, -2) and R(8, z) are
Hatshy [7]

Answer:

z = 3

Step-by-step explanation:

Since the points are collinear then the slopes between the points are equal.

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = P (2, - 3) and (x₂, y₂ ) = Q (3, - 2)

m = \frac{-2+3}{3-2} = 1

Repeat with

(x₁, y₁ ) = Q (3, - 2) and (x₂, y₂ ) = R (8, z )

m = \frac{z+2}{8-3} = \frac{z+2}{5} , then

\frac{z+2}{5} = 1 ( multiply both sides by 5 )

z + 2 = 5 ( subtract 2 from both sides )

z = 3

HIGH SCHOOL MATH ....
umka21 [38]

Answer:

The value of B (base\ area) = 27m^2

Step-by-step explanation:

Let's recall the the formula for volume of a pyramid.

Volume of a Pyramid = \frac{1}{3}\times B\times H}....equation (1)

where B=Base\ area (m^2) and H=height\ (m)

Now we have been given the values of V and H and have to find the value of B

Plugging the values of V and H in equation (1)

B=\frac{3\times V}{H}= \frac{3 \times 81}{9} = 27\ m^2

Now we can also check our previous results.

V = \frac{24\times 7}{3}=8 \times 7 =56\ m^3

So, our final answer is 27\ m^2
