Lucy and Emily are racing with each other and Lucy is 90
Zina [86]

Using the <em>system of equation</em> created, Emily will catch up Lucy after 30 seconds

Given the Parameters :

  • Lucy's distance = 2t
  • Emily's distance = 5t

<u>We can set up an equation to represent the required scenario thus</u> :

Emily's distance = Lucy's distance + 90

5t = 2t + 90

We solve for t

<em>Collect like terms</em> :

5t - 2t = 90

3t = 90

Divide both sides by 3 to isolate t

t = 90/3

t = 30

Therefore, Emily will catch up with Lucy after 30 seconds

What is the equation of a line that is parallel to the line x=-2and passes through the point (-5, 4)?
Nimfa-mama [501]
First, it is important to understand that any equation that is x=some number is just a vertical line that hits the x-axis at the given number. For example, x=-2 would be a vertical line hitting the x-axis at -2. Therefore, the line we are trying to identify would also be vertical (and have the form x=some number) because we know the lines are parallel. Then, since we're given the point (-5,4), we know the line needs to hit the x-axis at -5, therefore the equation would be x=-5.

I hope this helps.

A farm has a small water tank with a diameter of 10 feet and a height of 4 feet. What is the lateral surface area of the water t
svp [43]
The Shape in this question is a cylinder
And the formula for finding the L.S.A of a cylinder is 2*pie*r*h
From the question, we are given the diameter so to get the radius we will divide the value for diameter by 2
D = 10/2
    =5
Now, 2*3.14*5*4
L.S.A =125.6

What is the answer for this one ??
Arisa [49]

Answer: D

Step-by-step explanation:

A. 3 + -7 < -4

    -4 < -4

        X

    this one isn’t a solution

B. 3 + -7 ≤ -4

   -4 ≤ -4

   this works, let’s try the other equation

   3(3) + 2(-7) < -5

    9 + -14 < -5

     -5 < -5

       X

     this one doesn’t work either, let’s go on to the next one

C. the first equation is the same as the first one in A, and that didn’t work, so we know that the whole thing doesn’t work and we don’t have to do any math

D. we know the first equation works because we did it in B

    let’s go on to the second equation

    3(3) + 2(-7) ≤ -5

     9 -14 ≤ -5

     -5 ≤ -5

      this works, so that means that both equations work and the whole thing works :)
