I need an answer ASAP, I will mark u brainliest if the answer is valid! thx

Answers

Answer:

C

Explanation:

The answer is C because when you plug in (-3.4) as x in that equation, you get 2.3 as an answer which means that option is correct.

[tex]y = \frac{1}{2} x + 4[/tex]

[tex] = \frac{1}{2} ( - 3.4) + 4[/tex]

[tex] = 2.3[/tex]

When you plug in x for other options, you do not get the correct value for y so this is the only answer.

[tex]50.04[/tex]

Step-by-step explanation:

Use this formula for arc length

[tex]2\pi \times r( \frac{x}{360} )[/tex]

where r is the radius and x is the arc measure.

We know Arc de is 8.73 so we are finding x.

R equal 10.

[tex]2\pi \times 10( \frac{x}{360} ) = 8.73[/tex]

[tex]20\pi( \frac{x}{360} ) = 8.73[/tex]

[tex]20\pi \times x = 3142.8[/tex]

[tex]x = \frac{3142.8}{20\pi} [/tex]

x=50.04

The value of the angle will be 50.04.

What will be the angle?

It is given in the question that

The arc of the circle A=8.73 In

The radius of the circle =10 In

Now from the formula of arc

[tex]A=2\pi r(\dfrac{\theta}{360} )[/tex]

[tex]8.73=2\pi 10\times \dfrac{\theta }{360}[/tex]

[tex]\theta = \dfrac{8.73\times 360 }{ 2\pi\times 10} =50.04[/tex]

[tex]\theta=50.04[/tex]

Thus the value of the angle will  be 50.04

2. Eli has 600 cubes that are 1 cubic inch. Select the smallest length a cube- shaped box can have while being able to hold the 600 cubes. A 7 in. B 8 in. C 9 in. D 10 in.
​

Answers

Answer:

9 in

Step-by-step explanation:

We need to find x in x^3 > 600

For x=8, 8^3 = 512 < 600 (Too Small)

For x=9, 9^3 = 729 > 600 (Just right)

For x=10, 10^3 = 1000 > 600 (Too big)

Therefore, the smallest length of the cube-shaped box is 9 in.

how do i find the surface area and volume of this shape?

Answers

Answer:

3,761.46 m³

Step-by-step explanation:

Volume of a cone = 1/3πr²h

π = 3.14

radius, r = diameter/2

= 25/2 = 12.5 m

Height, h = 23m

Volume of a cone = 1/3πr²h

= 1/3 * 3.14 * 12.5² * 23

= 1/3 * 3.14 * 156.25 * 23

= 11,284.375 / 3

= 3761.4583333333

Approximately,

Volume of the cone = 3,761.46 m³
