Step-by-step explanation:

Pyramid

1/2 * 12 * 15

6 * 15 = 90

90 * 4 = 360cm

Cube

12 * 12 = 144

144 * 4 = 576cm

576 + 360 =

936 cm² of paint

What is an equation of the line that passes through the point (8,-8)(8,−8) and is perpendicular to the line 4x-3y=184x−3y=18?

Kitty [74]

Answer:

The equation of the line is $y = -\frac{3x}{4} - 2$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept.

Perpendicular lines:

When two lines are perpendicular, the multiplication of their slopes is -1.

Perpendicular to the line 4x-3y=18

First, we place this line into the format, to find the slope:

$4x - 3y = 18$

$3y = 4x - 18$

$y = \frac{4x}{3} - 6$

This line has slope 4/3. So, for the perpendicular line, the slope will be of m as such:

$\frac{4m}{3} = -1$

$4m = -3$

$m = -\frac{3}{4}$

So the desired line will have an equation in the following format:

$y = -\frac{3x}{4} + b$

Passes through the point (8,-8)

We use this to find b. This point means that when $x = 8, y = -8$ . So

$y = -\frac{3x}{4} + b$

$-8 = -\frac{3*8}{4} + b$

$-8 = -6 + b$

$b = -2$

$y = -\frac{3x}{4} - 2$

LUCKY_DIMON [66]

Answer:

80 blue

Step-by-step explanation:

r=red

b=blue

4b+2r=6 lights in one light cluster

120/6=20 clusters

Which mathematical property is demonstrated 40•(25•74) = (40•25)•74

Sindrei [870]

The mathematical property that allows 40 * (25 * 74) = (40 * 25) * 74 would be the Associative Property of Addition and Multiplication. This property means that no matter how the values of an expression are grouped together (or "associating" with each other), the end result will be the same, as long as the symbols are all either multiplication or addition symbols.
Hope that helped =)
