USE A MODEL Olivia and her brother William had a bicycle race. Olivia rode at a speed
Anni [7]

Answer:

Let the total distance Aileen ran be 'x'

Let the distance ran by Andrew be 'y'

Refer to graph attached for graphical representation of distance travelled by both.

Applying the formula,

distance=speed*time

x=20*t      Equation  1

y= 15*t       equation 2

Since it can be easily understood by the graph attached, that

x=150+y  equation 3

Now putting values of x and y in equation 3

20*t =150 +15*t.

5t= 150

t=30 seconds.

putting the values of t in both the equation 1 and 2

x=20t

=20*30

x  = 600 feet

So the distance ran by Aileen is 600 feet, whereas Andrew ran 450 feet.

Step-by-step explanation:

Do not mind the names just change them. I had the same question before with different names so that is why. Hope this helps:)

lawyer [7]
Well , in 3 hours , the amount of the tank that will be filled with pipe A = 8,000 x 3 = 24,000 L

Pipe could empty that 24,000 L in 3 hours.

So the capacity is  around 6 - 8 L .  .. . we need additional information to find out for sure

hope this helps

Savings account with 200$ and receive 4% interest for 7 years, how much would be in the account?
Fantom [35]

Answer:

256

Step-by-step explanation:

To calculate these kinds of things, I multiply the principal (200), the interest rate (0.04) and the time (7). This results in 56. However, since the question is how much would be in the account, it would be 200+56 which is 256.
