Answer:

a. -3/4 b. 4/3

Step-by-step explanation:

a.

To find the slope of a line, use the equation (y2 - y1) / (x2 - x1).

Plugging the values into the equation, you get (-5 - -8) / (0 - 4) = 3/-4

Thus, the slope of line <em>p</em> is -3/4.

b.

A perpendicular line is just one with a slope that is the opposite reciprocal of the original line. You find the slope value by flipping the fraction and adding the opposite sign (if it was originally positive, the perpendicular line should be negative, and vice versa).

So, the slope of line <em>r</em> is 4/3.

Answer:

33.8

Step-by-step explanation:

1) Use Phythagoras theorem to get RS ↓

$9.1 ^{2} + 6 ^{2} = 118.81 \\ \sqrt{118.81 } = 10.9$

2) RS = RQ

therefore, to get the perimeter, you'll have to total up the sides of the triangle ↓

$rs + rq +qt + ts \\ = 10.9 + 10.9 + 6 + 6 \\ = 33.8$

Hope this helps =)

Answer:

-44 4/9

Step-by-step explanation:

-36 4/9-(-10 2/9)-(18 2/9)

-36 4/9+10 2/9 = 26 6/9

26 6/9 - (18 2/9)= -44 4/9

The original cost of Sam’s investment is $10,000. After liquidating the investment, Sam calculated his real return to be $10,700

Sati [7]

Answer:

7%

Step-by-step explanation:

Step one:

given data

The original cost of Sam’s investment is $10,000

Sam calculated his real return to be $10,700

Required:

the interest made from the investment is

10700-10000= $700

Step two:

The ROI is a percentage that tells us the interest made

interest/investment*100

=700/10000*100

=0.07*100

= 7%

The ROI is 7%

Answer:

The correct option is (b).

Step-by-step explanation:

The formula for the side of a cube of surface area SA is as follows :

$s=\sqrt{\dfrac{SA}{6}}$

When SA = 180 m²

$s=\sqrt{\dfrac{180}{6}}\\\\s=\sqrt{30}$

When SA = 120 m²

$s=\sqrt{\dfrac{120}{6}}\\\\s=\sqrt{20}\\\\=2\sqrt5$

Difference,

$=30-2\sqrt5$

So, the correct option is (b).
