The final task is a bit more difficult. The bookshelf consists of two cubes and each cube has a side of (1/2). This is a fractio

nal base, so the expression for both cubes looks like this: (1/2)^3 x 2. Calculate the volume of the bookshelf to complete your training!

1/4

Step-by-step explanation:

I think that the expression is correct

(1/2)^3 x 2 = 1/8 x 2 = 1/4

Answer:

(x-6)(4) = 4x-24 (Answer is 4x-24)

Step-by-step explanation:

<u>ok here's the step </u>

<h2><u>(x-6)(4) so you do this read it </u></h2><h2><u>so the steps are =(x+−6)(4)</u></h2><h2><u>=(x)(4)+(−6)(4) so then you will get 4x-24</u></h2><h2><u></u></h2>

If PQRS is a rectangle, find the length of QT

MAVERICK [17]

Step-by-step explanation:

Since, opposite sides of a rectangle are equal and each angle is of 90°.

$\therefore$ QP = RS = 14 cm

$In \:\triangle QPS, \: \angle QPS = 90\degree$

$\therefore \: QS= \sqrt{QP^2+ PS^2} \\ \therefore \: QS= \sqrt{(14)^2+ (20)^2 } \\ \therefore \: QS= \sqrt{196 + 400} \\ \therefore \: QS= \sqrt{596} \\ \therefore \: QS= 24.41 \: m$

$\because$ Diagonals of a rectangle bisects each other.

$\therefore\: QT = \frac{1}{2} QS\\\therefore\: QT = \frac{1}{2} \times 24.41\\\therefore\: QT =12.205\\\huge\orange {\boxed {\therefore\: QT =12.21\:m}}$

Please answer and i have to show work

stealth61 [152]

Answer:

B

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to $\frac{3}{2}$

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

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (r, - 4)

m = $\frac{-4-2}{r-3}$ = $\frac{-6}{r-3}$ , then equating gives

$\frac{-6}{r-3}$ = $\frac{3}{2}$ ( cross- multiply )

3(r - 3) = - 12 ( divide both sides by 3 )

r - 3 = - 4 ( add 3 to both sides )

r = - 1 → B
