I need answer ASAP. What are the number of faces: What's the surface area of the shape? What is your work/equation for the answer of the surface area?| I WILL MARK BRAINLIEST.​

Answer:

simplifying this expression (√8^4 × √6^4)^3/2 = 110592

so 2^12 ×3^3= 110592

similar 2^9 ×6^3 =110592

100+2y = 180

2y=180-100

2y=80

y=40

Answer:

7 or -7

Step-by-step explanation:

the question is asking for x to to the second power which is x squared or x^2

so setting x^2=49

square root both sides of the equation so that x is by itself and the other side is just ±√(49). which ±√49 is just 7 or -7

Hope that helps :)

Answer:

[tex]x=-15.8994[/tex]

Step-by-step explanation:

Skills needed: Solving one variable equations, Multiplication

1) We are given: [tex]-11.818=-7+\frac{x}{3.3}[/tex], and we need to solve for "[tex]x[/tex]"

2) In order to do this, you need to isolate the variable. In other words, you need to make sure the term involving  "[tex]x[/tex]" is on one side of the equation, while everything else is on the other side.

3) [tex]-11.818+7 = -7+\frac{x}{3.3} +7[/tex]

[tex]-11.818+7=-4.818[/tex]

-7 and 7 on the right side cancel out.

4) So you are left with: [tex]-4.818=\frac{x}{3.3}[/tex]

5) So then: [tex]-4.818 * 3.3 = x[/tex] (that star sign in between -4.818 and 3.3 is a multiplication sign)

[tex]-4.818*3.3 = -15.8994[/tex], so [tex]x = -15.8994[/tex]

Step-by-step explanation:

Given:

In triangle RST, SQ=8 and QT=12.

To find:

The measure of sides SW and UQ.

Solution:

We know that centroid of a triangle is the intersection point of the medians and it divides each median in 2:1.

In the given figure SW and TU are medians and Q is the centroid. So,

[tex]\dfrac{SQ}{QW}=\dfrac{2}{1}[/tex]

[tex]\dfrac{8}{QW}=\dfrac{2}{1}[/tex]

[tex]\dfrac{8}{2}=QW[/tex]

[tex]4=QW[/tex]

Now,

[tex]SW=SQ+QW[/tex]

[tex]SW=8+4[/tex]

[tex]SW=12[/tex]

TU is a median. So,

[tex]\dfrac{QT}{UQ}=\dfrac{2}{1}[/tex]

[tex]\dfrac{12}{UQ}=\dfrac{2}{1}[/tex]

[tex]\dfrac{12}{2}=UQ[/tex]

[tex]6=UQ[/tex]

Therefore, the measure of SW is 12 units and the measure of UQ is 6 units.

They share  a common arm and common vertex.

Adjacent angles are not always equal in measure

Vertical angles: When two lines intersect each other, then the pair of opposite angles formed at the vertex are called vertical angles.

They share a common vertex, but no common arm.

Vertically opposite angles are equal in measure.

V≈55.98

Step-by-step explanation:

V=WHL=1.33x4.67x9≈55.978

Given:

The graph of a sine function.

To find:

The sine function.

Solution:

The general form of a sine function is

[tex]y=Asin(Bx+C)+D[/tex]            ...(i)

Where, |A| is amplitude, [tex]\dfrac{2\pi}{B}[/tex] is period, [tex]-\dfrac{C}{B}[/tex] is phase shift and D is mid-line.

From the given graph it is clear that the minimum value of the function is -4 and the maximum value is 0.

[tex]|A|=\dfrac{Maximum-Minimum}{2}[/tex]

[tex]|A|=\dfrac{0-(-4)}{2}[/tex]

[tex]|A|=\dfrac{4}{2}[/tex]

[tex]|A|=2[/tex]

The graph is reflected across the mid-line, so A=-2.

And,

[tex]D=\dfrac{Maximum+Minimum}{2}[/tex]

[tex]D=\dfrac{0+(-4)}{2}[/tex]

[tex]D=\dfrac{-4}{2}[/tex]

[tex]D=-2[/tex]

Period of the function is 4π because it completer its one cycle in the interval of 4π.

[tex]4\pi=\dfrac{2\pi}{B}[/tex]

[tex]B=\dfrac{2\pi}{4\pi}[/tex]

[tex]B=\dfrac{1}{2}[/tex]

Phase shift is [tex]\dfrac{\pi}{4}[/tex].

[tex]-\dfrac{C}{B}=\dfrac{\pi}{4}[/tex]

[tex]-\dfrac{C}{\frac{1}{2}}=\dfrac{\pi}{4}[/tex]

[tex]C=-\dfrac{1}{2}\times \dfrac{\pi}{4}[/tex]

[tex]C=-\dfrac{\pi}{8}[/tex]

Putting [tex]A=-2,B=\dfrac{1}{2},C=-\dfrac{\pi}{8},D=-2[/tex] in (i), we get

[tex]y=-2\sin\left(\dfrac{1}{2}x-\dfrac{\pi}{8}\right)-2[/tex]

Therefore, the required equation is [tex]y=-2\sin\left(\dfrac{1}{2}x-\dfrac{\pi}{8}\right)-2[/tex].

Step-by-step explanation: Khan Academy Explanation

The mean and standard deviation is given by -

μ = 0.35 and σ = 0.09.

Given is that suppose that 35% of students in a school can sing their national anthem correctly. The music teacher takes an SRS of 30 students from the population of 750 students at the school and finds that 40% of students sampled can sing their national anthem correctly. The teacher plans to take more samples like this. Let {p} represent the proportion of a sample of 30 students in the school who can sing their national anthem correctly.

        where -

        {σ} = population standard deviation

        {N} = the size of the population

        x{i} = each value from the population

        {μ} = the population mean

The mean and standard deviation is given by -

μ = 0.35

σ = √(0.35)(0.65)/(30) = 0.48/5.5 = 0.09

σ = 0.09

Therefore, the mean and standard deviation is given by -

μ = 0.35 and σ = 0.09

Step-by-step explanation:

[tex] \frac{1}{2} = 0.5 \\ \frac{2}{3} = 0.667 \\ \frac{3}{4} = 0.75 \\ \frac{5}{12} = 0.417[/tex]

in order to find d,we need to remove that 6 on 6d.so in order to remover 6,we divide both 6# and 108 by 6.so 6 divided by 6 we will be left with d = 108 devided by 6

Answer:

992.43 cm²

Step-by-step explanation:

From the question given above, the following data were obtained:

Volume of shape X (Vₓ) = 130 cm³

Surface area of shape X (SAₓ) = 202 cm²

Volume of shape Y (Vᵧ) = 638.69 cm³

Surface area of shape Y (SAᵧ) =?

The surface area of shape Y can be obtained as follow:

Since the shape are similar, then:

Vₓ / Vᵧ = SAₓ / SAᵧ

130 / 638.69 = 202 / SAᵧ

Cross multiply

130 × SAᵧ = 638.69 × 202

130 × SAᵧ = 129015.38

Divide both side by 130

SAᵧ = 129015.38 / 130

SAᵧ = 992.43 cm²

Thus, surface area of shape Y is 992.43 cm²

Answer: a=5

Step-by-step explanation: Use the pythagorean theorem and get

(a)^2+(12)^2=(13)^2

This would then be (a)^2+144=169

subtract 144 from both sides and get

(a)^2=25

Take the square root of both sides and you get a=5

Answer:

a=5

Step-by-step explanation:

Pythagorean theorem

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

substitute your values

[tex]a^{2}[/tex] + [tex]12^{2}[/tex] = [tex]13^{2}[/tex]

    - 12    - 12

[tex]a^{2}[/tex] = [tex]13^{2}[/tex] - [tex]12^{2}[/tex]

a = 169-144

a= 25

now find the square root of 25, which is 5

Answer:

1) [tex]sin \left(\dfrac{- \pi}{12} \right) = \dfrac{(\sqrt{2} - \sqrt{6} }{4}[/tex]

2) [tex]tan\left(\dfrac{ \pi}{12} \right) = 2 - \sqrt{3}[/tex]

3) [tex]tan\left(\dfrac{ 5\cdot \pi}{12} \right) = 2 + \sqrt{3}[/tex]

Step-by-step explanation:

1) [tex]sin \left(\dfrac{- \pi}{12} \right) = sin(-15^{\circ})[/tex]

sin(-15°)  = sin(30° + (- 45°)) = sin(30°)cos(-45°) + cos(30°)sin(-45°)

sin(30°)cos(-45°) + cos(30°)sin(-45°) = 1/2 × (√2)/2 + (√3)/2 × (-√2)/2

1/2 × √2/2 + √3/2 × -√2/2 = (√2)/4 - (√6)/4 = ((√2) - (√6))/4

sin(-15°)  = ((√2) - (√6))/4

[tex]sin \left(\dfrac{- \pi}{12} \right) = sin(-15^{\circ}) = \dfrac{(\sqrt{2} - \sqrt{6} }{4}[/tex]

2) [tex]tan\left(\dfrac{ \pi}{12} \right) = tan(15^{\circ})[/tex]

tan(15°)  = tan(45° + (-30°)) = (tan(-30°) + tan(45°))/(1 - tan(-30°)×tan(45°))

(tan(-30°) + tan(45°))/(1 - tan(-30°)×tan(45°)) = ((-1/√3) + 1)/(1 - (-1/√3))

((-1/√3) + 1)/(1 - (-1/√3)) = (3 - √3)/(3 + √3) = (3 - √3)·(3 -√3)/((3 - √3)·(3 + √3))

(3 - √3)·(3 -√3/((3 - √3)·(3 + √3)) = (9 - 6·√3 + 3)/(9 - 3) = (12 - 6·√3)/6

(2 - √3)

[tex]tan\left(\dfrac{ \pi}{12} \right) = tan(15^{\circ}) = 2 - \sqrt{3}[/tex]

3) [tex]tan\left(\dfrac{ 5\cdot \pi}{12} \right) = tan(75^{\circ})[/tex]

tan(75°)  = tan(30° + 45°) = (tan(30°) + tan(45°))/(1 - tan(30°)×tan(45°))

(tan(30°) + tan(45°))/(1 - tan(30°)×tan(45°)) = ((1/√3) + 1)/(1 - 1/√3)

((1/√3) + 1)/(1 - 1/√3) = (3 + √3)/(3 - √3) = (3 + √3)·(3 +√3/((3 - √3)·(3 + √3))

(3 + √3)·(3 +√3/((3 - √3)·(3 + √3)) = (9 + 6·√3 + 3)/(9 - 3) = (12 + 6·√3)/6

(12 + 6·√3)/6 = 2 + √3

[tex]tan\left(\dfrac{ 5\cdot \pi}{12} \right) = tan(75^{\circ}) = 2 + \sqrt{3}[/tex]

Answer: 2 hours=6 degrees C

              5 hours=-31 degrees C

               Half an hour=9.5 degrees C

Step-by-step explanation:

9 x 2 hours = 18 C        14-8= 6 degrees C

9 x 5 hours = 45 C       14-45= -31 degrees C

9 x 0.5 = 4.5 C              14-4.5= 9.5 degrees C
