Answer:

A. 1,485 cubic cm. B. 27

Step-by-step explanation:

The new prism is dilated by a factor of 3, that means it's made bigger, 3 times bigger on each side.

The dimensions of the new prism are then 12 cm by 7.5 cm by 16.5 cm.

Its volume is then of 12 x 7.5 x 16.5 = 1,485 cubic cm

To answer the second question...

Let's calculate the volume of the original prism:

The original prism's volume was 4 x 2.5 x 5.5 = 55 cubic cm

The new volume is then 1485 / 55 = 27 times bigger than the original.

Which is normal, since we increased each side (dimension) by a factor of 3, so 3x3x3 = 27.

The ratio of the longer side of a rectangle to its shorter side is 4 to 3. If the shorter side of the rectangle is 21ft, what is

Eduardwww [97]

Answer:

28 ft

Step-by-step explanation:

Let longer side of rectangle be $L$ and the shorter side be $S$ , thus we can write the ratio:

$\frac{L}{S}=\frac{4}{3}$

Now putting 21 into S, we solve for L:

$\frac{L}{21}=\frac{4}{3}\\3L=4*21\\3L=84\\L=\frac{84}{3}=28$

Hence, length of longer side is 28 ft.

HELP A line passes through two points with coordinates (6,-8) and (-3,7).

FromTheMoon [43]

Answer:

3y+5x=6

Step-by-step explanation:

Equation of the Line

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The line passes through the points (6,-8) and (-3,7), thus:

$\displaystyle y+8=\frac{7+8}{-3-6}(x-6)$

$\displaystyle y+8=\frac{15}{-9}(x-6)$

Simplifying:

$\displaystyle y+8=-\frac{5}{3}(x-6)$

Multiplying by 3:

$3(y+8)=-5(x-6)$

$3y+24=-5x+30$

Moving all the variables to the left side:

3y + 5x = 30 - 24

3y + 5x = 6
