Answer:

y = 5x

Step-by-step explanation:

Find the  slope of the line

Take the point where y = 20 and x = 4 .  That is the point  (4, 20)

Slope = rise / run = y / x = 20 / 4 = 5

Also the graph passes through (0,0)

So if we use the general  slope/intercept form

y = mx + c

m = 5 and c = 0

so the equation of the line is y = 5x + 0

y = 5x

Answer:

A

Step-by-step explanation:

the equation of a straight line passing through the origin is

y = mx ( where m is the slope )

calculate slope m using the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (2, 10 ) ← 2 points on the line

m = \frac{10-0}{2-0} = \frac{10}{2} = 5

y = 5x ← is the equation of the line

What is the approximate volume of a cone with a height of 6mm and radius of 18 use 3.14 to approximate pi
Mandarinka [93]

Hello from MrBillDoesMath!

Answer:

2035.8  (approximately)

Discussion:

The volume of a cone or radius r and height h is given by the formula:

Volume = (1/3) Pi * r^2 * h. In our case this is:

V = (1/3) Pi * (18)^2 * 6

   =(1/3) Pi * 324 * 6                      => 324/3 = 108

   = 108 * 6 Pi                                 => 108 *6 = 648

   = 648 * Pi                                    => approximating Pi by 3.14

   = 648 * 3.14

   = 2035.8  (approximately)

Thank you,

MrB

What will the movement of a point which is on the surface of a circle touching the ground at the same time, if the circle turns
lesya692 [45]

Answer:

183.26cm

Step-by-step explanation:

Radius of the Circle = 50cm

Let the point be at A

It turns forward 210 degrees to B.

Therefore, the central angle subtended by the arc AB = 210 degrees

The movement of the point from A to B will be the length of the arc AB.

\text{Length of an arc }=\dfrac{\theta}{360} \times 2\pi r \\$Therefore, the distance moved forward$\\=\dfrac{210}{360} \times 2\times\pi \times 50\\\\=183.26$ cm

To go on the class trip, chang needs at least $125. he has saved $45, and he makes $7 an hour at his job. what is the minimum nu
Murljashka [212]
The total amount that Chang will received from his wages is the product of his hourly wage times the number of hours he has worked (n). His total savings should not be less than $125. The equation that best describes the situation is, 
                                    45 + 7n ≥ 125
Solving for n in the inequality gives an answer of n≥11.42 hours. Thus, he needs to work for at least 12 hours.
