Please help me BIG POINTS

Mathematics
2 answers:
rodikova [14]4 years ago
5 0

Step-by-step explanation:

<u>Step 1:  Make an equation</u>

\frac{time_1}{people_1} = \frac{time_2}{people_2}

\frac{20}{150} = \frac{x}{240}

<u>Step 2:  Cross multiply</u>

20(240) = 150(x)

4800 = 150x

<u>Step 3:  Divide both sides by 150</u>

4800 / 150 = 150x / 150

32 = x

Answer: Option C, 32 min

Answer:

32minutes

Step-by-step explanation:

time for 150 people=20 min

time taken for 1 person =20÷150

time taken for 240 people=20÷150×240

=32

hope this helps

How do you get the equation of the line in fully simplified slope-intercept form?​
Igoryamba

Answer:

y= -2/5 x -4

Step-by-step explanation:

So the equation is y=mx+b. Where m=slope and b=y-intercept. To find b, you would see at what point does the line cross the y axis. That would be at -4 so, -4 would be the b or y-intercept. To find m, you would take two points on the line and use this equation:

m=(y2 - y1 )/(x2 - x1)

If you were using the points, (-10,0) and (0, -4) the equation would be:

m=(-4-0) / (0+10)

So, m= -2/5

The equation of the line would end up being:

y= -2/5 x -4

What is the distance rounded to the nearest tenth between the points (2 -2) and (6 3)
kotegsom [21]

Answer:

The distance between the points is approximately 6.4

Step-by-step explanation:

The given coordinates of the points are;

(2, -2), and (6, 3)

The distance between two points, 'A', and 'B', on the coordinate plane given their coordinates, (x₁, y₁), and (x₂, y₂) can be found using following formula;

l = \sqrt{\left (y_{2}-y_{1}  \right )^{2}+\left (x_{2}-x_{1}  \right )^{2}}

Substituting the known 'x', and 'y', values for the coordinates of the points, we have;

l_{(2, \, -2), \ (6, \, 3) } = \sqrt{\left (3-(-2)  \right )^{2}+\left (6-2  \right )^{2}} = \sqrt{5^2 + 4^2} = \sqrt{41}

Therefore, the distance between the points, (2, -2), and (6, 3) = √(41) ≈ 6.4.
