Answer:

5/4 or 1.25

Step-by-step explanation:

Slope of the line containing (2,6) & (7,2):

m = (y2-y1)/(x2-x1)

m = (2-6)/(7-2)

= -4/5

For Perpendicular lines,

m1×m2 = -1

(-4/5)×m2 = -1

m2 = -1 × (-5/4)

m2 = 5/4 or 1.25

. A rectangular prism has a volume of 1374.28 inches. The prism is 9.4 inches wide and 17.2 inches long. What is the height of t

VashaNatasha [74]

Answer:

h = 8.5 inches

Step-by-step explanation:

Given that,

The volume of a rectangular prism = 1374.28 inches³

The prism is 9.4 inches wide and 17.2 inches long.

We need to find the height of the prism. We know that the formula for the volume of rectangular prism is given by :

V = lbh

Where

h is the height of the prism

So,

$h=\dfrac{V}{lb}\\\\h=\dfrac{1374.28 }{9.4\times 17.2}\\\\h=8.5\ inches$

So, the height of the prism is equal to 8.5 inches.

In Ms.Khans class,22 out of 25 students hand in their projects on time. What percent of the class hand in their projects on time

Nikitich [7]

88 % students of the class hand in their projects on time

Solution:

Given that, Ms.Khans class, 22 out of 25 students hand in their projects on time

Total number students = 25

Students hand in their projects on time = 22

To find: percent of the class hand in their projects on time

$\text{ percent of class hand in time } = \frac{\text{Students hand in projects on time}}{\text{total students}} \times 100$

Substituting the values, we get

$\text{ percent of class hand in time } = \frac{22}{25} \times 100\\\\\text{ percent of class hand in time } = 0.88 \times 100\\\\\text{ percent of class hand in time } = 88$

Thus 88 % students of the class hand in their projects on time
