2[2x-2.2]=4.6 solve the equation

I believe the answer is (3,4)

Answer: - radical 7 / 4

Step-by-step explanation:

draw a triangle in quadrant III

plug in correct terms

use Pythagorean theorem

to simplify down to find the opposite angle

b= rad 7

The sum of the squared lengths of the other two sides of a right triangle equals the square of the hypotenuse's length, which can be defined as follows:

[tex]\to \cos \theta =-\frac{3}{4}[/tex]

[tex]\to \sin \theta =?[/tex]

[tex]\sin \theta = \frac{opposite}{hypotenuse}\\\\\cos \theta =\frac{hypotenuse}{adjacent}\\\\[/tex]

therefore

hypotenuse= -3

adjacent= 4

Using the Pythagorean theorem to find the opposite:

Hypotenuse²= Adjacent²+ Opposite²

[tex]-3^2= 4^2+x^2\\\\9=16+x^2\\\\x^2= -16+9\\\\x^2=-7\\\\x= -\sqrt{7}\\\\[/tex]

Therefore the value of sin θ [tex]= \frac{\sqrt{7}}{-3}= \frac{\sqrt{7}}{3}[/tex]

Answer:

55

Step-by-step explanation:

Answer : 55

Step by step explanation use PEMDAS

55/1 = 55

Answer:

x√3 = 5√ 3

x = 5√ 3 / √ 3

x= √ 3(5√ 3 / √ 3)

x= 15/3

b= 5

5x2 =10

a=10 and b=5

The ratio is already in lowest terms so we found an equivalent ratio by multiplying both terms by 2.

Answer:

Order matters in divisions of fractions. If you do not put them in the correct order, you will get different answers

Step-by-step explanation:

Answer:

Radius -  4

Apothem -  2

Area - [tex]12\sqrt{3}[/tex] or 20.8

Step-by-step explanation:

Try to draw out my explanation so you know what this looks like.

~~~~

This is an equilateral triangle, so all sides are the same length. The perimeter can be divided by 3 to get each side length...

[tex]12\sqrt{3} \div3 = 4\sqrt{3}[/tex]

Now that we know the side lengths, we can get this started!

~~~~

Now, an equilateral triangle has angles that all equal 60 degrees. We can bisect this into TWO special case triangles of measures 90-60-30.

4 times the square root of 3 will be the hypotenuse, and the smallest leg is always half of that. The larger leg is represented as the small leg times the square root of 3.

[tex]Small=2\sqrt{3} \\Hypotenuse = 4\sqrt{3} \\Long =6[/tex]

By the way, the formula for the area can be either of the two:

[tex]A= \frac{1}{2} bh\\or\\A = \frac{1}{2} NAS[/tex]

we can easily find the area using the first formula.

[tex]A= \frac{1}{2} (4\sqrt{3} )(6)\\A=12\sqrt{3}[/tex]

The radius is the distance from the center to the corners & the apothem is the distance from the center to a side...

So we can divide the big triangle into a mini triangle at the bottom left/right

The height (small leg) of that triangle would be the apothem

The hypotenuse of that triangle would be the radius.

I did the math really quick because this is getting long. Anyhow, the small leg is 2 so is the apothem, and the hypotenus is 4, so is the radius

Answer: 80.49.

Can u give me brainliest

Step-by-step explanation:

Answer:

85

Step-by-step explanation:

The hypotenuse is 85

The equation for pythagorean theorem is a squared+ b squared= c squared.

7 and 11 squared is 49 and 121

Add them together and then divide the answer by half and you get 85

Answer: 24

Step-by-step explanation:

Given

Pilar made 6 quarts of orange marmalade

If each jar stores [tex]\frac{1}{4}\ \text{or}\ 0.25[/tex] quart of marmalade then

No of jars required to store marmalade is

[tex]\Rightarrow n=\dfrac{6}{\frac{1}{4}}=\dfrac{6\times 4}{1}=24\ \text{jars}[/tex]

Answer:

24

Step-by-step explanation:

Okay she got 6 quarts of orange marmalade and she pouring 1/4 quarts into a jar.

I will draw out the problem for you

1/4 + 1/4 +1/4 + 1/4 = 1 quart

1/4 + 1/4 +1/4 + 1/4 = 2 quart

1/4 + 1/4 +1/4 + 1/4 = 3 quart

1/4 + 1/4 +1/4 + 1/4 = 4 quart

1/4 + 1/4 +1/4 + 1/4 = 5 quart

1/4 + 1/4 +1/4 + 1/4 = 6 quart

and if u count all the 1/4 in the thing I just type, it will be 24

Answer: 4 hours, $160
