Barba can walk 3200 meters in 24 minutes.How far can she walk on 3 mins
SashulF [63]

Answer:

400 meters in 3 minutes

Step-by-step explanation:

First find  how far she can walk in 1 minute.

3200/24 = 133 1/3.

She can walk 133 1/3 meters in 1 minute. If we want to find out how far she can walk in 3 minutes. Multiply that number by 3.

133 1/3 * 3 = 400.

Hope that helps.

Find the equaton of the line passing through the points (2,11) and (-8, -19) y= ?x ?​
antoniya [11.8K]

Find the slope:

(-19 - 11) / (-8 - 2) = (-30/-10) = 3

Find the y intercept:

y = mx + b

11 = 3(2) + b

b= 5

So equation is:

y = 3x + 5

love history [14]

Answer:

  • v = 5.6m

Step-by-step explanation:

<u>Proportional relationship equation:</u>

  • y = kx, where k- constant of proportionality

<u>Use the given point to work out the value of k:</u>

  • 28 = 5k
  • k = 28/5
  • k = 5.6

<u>In our case the equation is:</u>

  • v = 5.6m, where v- volume, m- mass

Sec (a) + tan (a) = sec (a) – tan (a)
Mariulka [41]

Answer:

a = π n for n element Z

Step-by-step explanation:

Solve for a:

sec(a) + tan(a) = sec(a) - tan(a)

Subtract sec(a) - tan(a) from both sides:

2 tan(a) = 0

Divide both sides by 2:

tan(a) = 0

Take the inverse tangent of both sides:

Answer:  a = π n for n element Z
