What is the slope of the line that passes through the point (-9,8) and (-3-1)?

natulia [17]

Answer:

Step-by-step explanation:

(x₁, y₁) = (-9 ,8) and (x₂ , y₂) = (-3 , -1)

$Slope = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{-1-8}{-3-[-9]}\\\\=\dfrac{-9}{-3+9}\\\\=\dfrac{-9}{6}\\\\=\dfrac{-3}{2}$

You can use trigonometry and the tangent to get:
tan(11°)=150/x
so x=772 ft

Every year Ethan earns 38,428. Each year he spends 21,728 on expenses. How much money should he have left over?

PolarNik [594]

Answer:

16,700

Step-by-step explanation:

Given that,

Earning of Ethan = 38,428

Ethan spends 21,728 on expenses.

We need to find the amount of money he has left over. It can be calculated as follows :

Left money = Earning - Spent

= 38,428 - 21,728

= 16,700

So, he has left over 16,700.

Find MO and PR ............................................................

ddd [48]

MO = 12 and PR = 3

Solution:

Given $\triangle M N O \sim \Delta P Q R$ .

Perimeter of ΔMNO = 48

Perimeter of ΔPQR = 12

MO = 12x and PR = x + 2

If two triangles are similar, then the ratio of corresponding sides is equal to the ratio of perimeter of the triangles.

$$\Rightarrow \frac{\text{Perimeter of }\triangle MNO}{\text{Perimeter of }\triangle PQR} =\frac{MO}{PR}$

$$\Rightarrow \frac{48}{12} =\frac{12x}{x+2}$

Do cross multiplication.

$$\Rightarrow 48({x+2})= 12(12x)$

$$\Rightarrow 48x+96= 144x$

Subtract 48x from both sides.

$$\Rightarrow 48x+96-48x= 144x-48x$

$$\Rightarrow 96= 96x$

Divide by 96 on both sides, we get

⇒ 1 = x

⇒ x = 1

Substitute x = 1 in MO an PR.

MO = 12(1) = 12

PR = 1 + 2 = 3

Therefore MO = 12 and PR = 3.
