Find the slope of the line passing through the points (-2,3) a and (-9,6).

larisa [96]

<h3>Answer: Slope = -3/7</h3>

===================================================

Apply the slope formula

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

m = (6-3)/(-9-(-2))

m = (6-3)/(-9+2)

m = 3/(-7)

m = -3/7

This means each time you go down 3 units, you go to the right 7 units.

Slope = rise/run = -3/7

rise = -3 and run = 7

Let

h-----> the high of the balloon

we know that

In the right triangle of the figure

$tan(63\°)=\frac{4}{h}$

$h=\frac{4}{tan(63\°)}$

$h=2.04\ miles$

Angle A and Angle B are complementary angles. If angle B is five degrees more than four times angle A, find the measure of each

kupik [55]

Answer:

Angle A = 17°, Angle B = 73°

Step-by-step explanation:

Angle A & Angle B are complementary angles (given) so they will form 90°.

Let's take,

Angle A = x

Angle B = 4x +5 (angle B is five degrees more than four times angle A)

Measure of each angle=?

Angle A + Angle B = 90°

x + 4x + 5 = 90

5x + 5 = 90

5x = 90 - 5

5x = 85

x = 85 ÷ 5

x = 17°

Angle A = x = 17°

Angle B = 4x + 5 = 4(17) + 5 = 68 + 5 = 73°

Answer/Step-by-step Explanation:

==>Given:

Ratio of cost of 1m polyester fabric to 1m of cotton fabric = 2:7

I.e. if 1m of polyester fabric = £2, then 1m of cotton fabric = £7.

==>Required:

a. Cost of polyester fabric for the following lengths:

i) 6m ii) 8m iii) 9m

Thus, having known that cost of 1m polyester fabric = £2, therefore,

i) 6m polyester fabric = 6×2 = £12

ii) 8m polyester fabric = 8×2 = £16

iii) 9m polyester fabric = 9×2 = £18

b. Cost 8 cotton fabric for the following lengths:

i) 2m ii) 6m iii) 8m iv) 9m

Thus, since 1m of cotton fabric = £7, therefore,

i) 2m cotton fabric = 2×7 = £14

ii) 6m cotton fabric = 6×7 = £42

iii) 8m cotton fabric = 8×7 = £56

iv) 9m cotton fabric = 9×7 = £63
