Semenov [28]

Answer:

7 1/2 quart of paint

Step-by-step explanation:

To get the correct color, Johan mixed 3 1/4 quart of white paint, 1 2/4 quart of blue paint, and 2 3/4 quart of green paint. How much paint did Johan make? *

The above question is solved as:

3 1/4 quart + 1 2/4 quart + 2 3/4 quart

Lowest common denominator = 4

3 + 1 + 2 + ( 1/4 + 2/4 + 3/4)

= 6 + ( 1 + 2 + 3/4)

=( 6 + 6/4) quart

= 6 + 1 2/4 quart

= 7 2/4 quart of paint

= 7 1/2 quart of paint

Therefore, Johan made 7 1/2 quart of paint

Write the point slope form of the line that passes through (-8,2) and is perpendicular to a line with a slope of -8
Fynjy0 [20]

Answer:

y - 2 = \frac{1}{8}(x +8)

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. Since the slope of one line is -8, its perpendicular line will have the slope of 1/8.

Substitute m = 1/8 and (-8,2) into the point slope form of a line.

y - y_1 = m(x-x_1)\\y - 2 = \frac{1}{8}(x --8)\\y - 2 = \frac{1}{8}(x +8)
