Sergio039 [100]

Answer:

130°

Step-by-step explanation:

the opposite angle just like in the diagram will always be the same value

then you must know that total angle in triangle must be 180° so the balance angle each 50° bcuz when the length is the same, the angle should be the same too.

to find X , 180-50=130

Wally chin, the owner of an exxon mobil station, bought a used ford pickup truck, paying $1,900 as a down payment. He still owes

My name is Ann [436]

Down payment of the ford pickup truck = $1,900.

It is said that down payment amount $1,900 owes 75% of the selling price.

Therefore, 100-75 = 25% is the downpayment of total Selling price.

Let is assume selling price is $x.

According to problem,

25% of the selling price equals down payment amount $1,900.

Let us convert above statement into an equation.

25% of x is 1,900.

That is 25% x = 1,900.

25% could be written as 25/100 or 0.25.

So, the above equation would become

0.25x = 1,900.

Dividing both sides by 0.25, we get

0.75x/0.25 = 1,900/0.25

x=7600

So, the selling price would be $7600.

There's a pair of points (3,5), (x,15) and a slope of 2 how do I find x

sergeinik [125]

You have the slope and you have two points, so you can use the slope equation to find x.

$b=\frac{(y_2-y_1)}{(x_2-x_1)} \\2=\frac{(15-5)}{(x-3)} \\2(x-3)=(15-5)\\2x-6=10\\2x=16\\x=8$

So your answer is x = 8.

It sounds like R is the region (in polar coordinates)

R = {(r, θ) : 2 ≤ r ≤ 3 and 0 ≤ θ ≤ π/2}

Then the integral is

$\displaystyle \iint_R\frac{\mathrm dx\,\mathrm dy}{\sqrt{x^2+y^2}} = \int_0^{\pi/2}\int_2^3 \frac{r\,\mathrm dr\,\mathrm d\theta}{\sqrt{r^2}} \\\\ = \int_0^{\pi/2}\int_2^3 \mathrm dr\,\mathrm d\theta \\\\ = \frac\pi2\int_2^3 \mathrm dr \\\\ = \frac\pi2r\bigg|_2^3 = \frac\pi2 (3-2) = \boxed{\frac\pi2}$
