Sam was still finishing his breakfast when his brother Leo left for school. Sam started to run after Leo when Leo was already 10

0 meters away. How soon will Sam catch up, if he is running at a speed of 105 meters per minute while Leo is walking at a speed of 65 meters per minute?

Quality Assurance

The answer to this question would be: 2.5 minute

In this question, when Sam started to run Leo was already 100 meters away. But Sam runs 105m/min which was faster than Leo(65m/min).

Then the time needed for Sam to catch up Leo should be:

time= distance / (Sam speed-Leos peed)

time= 100m/ (105-65m/min)

time= 100m/(40m/min)= 2.5min

Write the equation if this line below​
Alexxandr [17]

Answer:

Step-by-step explanation:

The first step to finding the equation of this line we must find two points that are on this line.

Two points on the lines are (0,3) and (1,0).

Now we must find the slope:

   slope = \frac{y2-y1}{x2-x1}  = \frac{3 - 0}{0-1} =-3

Now after finding the slope which is -3, now let us put it into the point-slope form using the point (0,3) which is also on the line. You could also use (1,0) in this case, but I am using (0,3).

y-3 = -3(x-0)\\y=-3x +3

Thus the equation is y=-3x +3

Hope that helps!

the greatest common factor gcf of 2 monomiald is 3x^2y. One of the monomials is 3x^4y . Which couod be the other monomial.
fomenos
While I cannot see your answer choices, the correct answer would be one that has a coefficient that is a multiple of 3 and has an x raised to an exponent of no more than 2.  It could have any other variables in it.

The reason this has to be is because of the GCF.  Since 3 is part of the GCF, and the other monomial has a coefficient of 3, this means the missing monomial must be divisible by 3 as well.

Since x² is part of the GCF, the missing monomial must contain x².  However, if it were to contain x³ or anything larger, the GCF would have x with a higher exponent.

Area of a Circle Formula: A = πr²

  • <em>r</em> is radius

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>r</em> = 6.5 m

<u>Step 2: Find Area</u>

  1. Substitute in variables [Area of a Circle Formula]:                                         A = (3.14)(6.5 m)²
  2. Evaluate exponents:                                                                                         A = (3.14)(42.25 m²)
  3. Multiply:                                                                                                             A = 132.732 m²
  4. Round:                                                                                                               A ≈ 132.73 m²
