Please help me I will mark BRAINLIEST!!! Find the value of x

Basile [38]

Answer:

x = 2√3 ≈ 3.464

Step-by-step explanation:

The side marked x is opposite the given 30° angle. The side marked 6 is adjacent to that angle. The trig function relating opposite and adjacent sides of a right triangle is ...

Tan = Opposite/Adjacent

Filling in values, we have ...

tan(30°) = x/6

Multiplying by 6 gives ...

x = 6tan(30°) = 6(√3/3)

x = 2√3 ≈ 3.464

Answer:

$4.00

Step-by-step explanation:

We assume the price is proportional to the quantity of oranges. If p is the desired price in dollars, we want ...

p/8 = 0.25/(1/2)

p = 8(0.50) = 4.00 . . . . multiply by 8, simplify

8 kg of oranges would cost $4.00.

12. Find the distance between points P(-1, 2) and Q(-3, 4).

marusya05 [52]

Answer:

D=2.82

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (-1,2)$

$(x_2,y_2) = (-3,4)$

Replacing these values in the distance formula

$D =\sqrt{(-1-(-3))^2+(2-4)^2}$

$D =\sqrt{(-1+3)^2+(-2)^2}$

$D =\sqrt{(2)^2+4}$

$D =\sqrt{4+4}$

$D =\sqrt{8}$

$D= 2.8284$

Hence the Distance is 2.82 units
