Answer:

[tex]x=\frac{3}{4}[/tex]

Step-by-step explanation:

First, we know we want to get x all by itself. So, let's multiply it by 2.

[tex]\frac{2}{x}(2) = \frac{3}{4}(2)\\[/tex]

Then we have:

[tex]x=\frac{3}{4}(2)[/tex]

Now, we have to simplify the right side of the equation, so, let's rewrite it.

[tex]x=\frac{3*2}{4*2}[/tex]

All we have to do now is simplify.

[tex]x=\frac{6}{8}[/tex]

Luckily (and ironically) both the numerator and denominator are divisible by 2, so...

[tex]x=\frac{3}{4}[/tex]

I hope this helps!

Answer:

79.1

Step-by-step explanation:

Given that :

Mean, μ = 62

Standard deviation, σ = 5.7

The value, x that is +3 standard deviations from the mean :

x = μ + 3(σ)

x = 62 + 3(5.7)

x = 62 + 17.1

x = 79.1

Step-by-step explanation:

To define the time of flight equation, we should split the formulas into two cases:

Launching projectile from the ground (initial height = 0)

t = 2 * V₀ * sin(α) / g.

Launching projectile from some height (so initial height > 0)

t = [V₀ * sin(α) + √((V₀ * sin(α))² + 2 * g * h)] / g.

Hi your answer is 144 i don't how i got but it is 144

Answer:

C is the correct answer.

Step-by-step explanation:

All of the angles in a triangle add up to 180 degrees. 65+80=145 and when you do 180-145, you get 35 degrees. You can check to see if it's correct by adding 35, 65, and 80 together.

[tex]65+80=145[/tex]

[tex]180-145=35[/tex]

[tex]35+65+80=180[/tex]

The opposite angle of the triangle is similar.ΔDEF is similar to ΔABC. Option C is correct.

What exactly is a triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

ΔDEF

∠F=80°

∠F=35°

The sum of the angle of the triangle DEF is;

∠D+∠E+∠F=180°

∠D=180°-115°

∠D=65°

In ABC

/_A = 65°

/_B= 80°

∠A+∠B+∠C=180°

∠D=180°-145

∠D=35°

The opposite angle of the triangle is similar.ΔDEF is similar to ΔABC.

Hence,option C is correct.

Answer:

A.) 127.16π

Step-by-step explanation:

Volume of a cylinder = πr²h

Radius, r = 3.4m

Height, h = 11m

Pi = π

Find the volume in terms of pi

Volume of a cylinder = πr²h

= π * (3.4)² * 11

= π * 11.56 * 11

= 127.16π³

The correct answer is

A.) 127.16π

Answer: 150 degrees

Step-by-step explanation:

The line around the angles that measure 35 degrees shows that those are equal so both are 35 degrees. Then you add 35+35+140. You then subtract that value from 360 since a whole circle measures 360 degrees.

Answer:

Option A

Step-by-step explanation:

C and D are scattered showing no pattern, Therefore, it is either A or B. I say it's not B due the the fact more studying minutes made even less test grades. So A is the only option left.

Answer:

[tex]P(Red) = 0.44[/tex]

Step-by-step explanation:

The question required a tree diagram (see attachment)

Required

Determine P(Red)

To do this, we simply each path that leads to red on the attached tree.

So, we have:

[tex]Red\ 1 = 0.35 * 0.6[/tex]

[tex]Red\ 2 = 0.45 * 0.2[/tex]

[tex]Red\ 3 = 0.20 * 0.7[/tex]

P(Red) is then calculated as:

[tex]P(Red) = Red\ 1 + Red\ 2 + Red\ 3[/tex]

[tex]P(Red) = 0.35 * 0.6 + 0.45 * 0.2 + 0.20 * 0.7[/tex]

[tex]P(Red) = 0.44[/tex]

Hence, the probability of selecting Red is 0.44

Answer:

35 square units

Step-by-step explanation:

Area is length • width, so you just have to count the number of units long and wide the rectangle is.

The length is 5 units and the width is 7 units, therefore, you would do 5•7.

5•7=35

Step-by-step explanation:

Answer:

A. 1206 cm³

Step-by-step explanation:

We have a cone and are asked to find the approximate volume of it.

Keep in mind we are using π for 3.14

The forumla of a cone is V = πr²[tex]\frac{h}{3}[/tex]

We know the radius = 12

and the height = 8

Substitute :

V = π12²[tex]\frac{8}{3}[/tex]

Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:

V = [tex]\frac{2^4*3^2*8\pi }{3}[/tex]

Cancel the common factor - 3 :

V = [tex]2^4 * 8 * 3\pi[/tex]

Multiply 8 and 3π :

V = [tex]2^4 * 24\pi[/tex]

Solve the exponent :

V = [tex]16 * 24\pi[/tex]

Multiply :

V = [tex]384\pi[/tex]

Multiply for the final answer :

1205.76 cm³

which can be rounded up to

A. 1206 cm³
