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.

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

Georgia has a budget of $8 for a new notebook. She wants to spend within $5 of her budget, so she uses the equation 5 = |8 – x|

siniylev [52]

Answer:

Minimum: 3

Maximum: 13

Step-by-step explanation:

Georgia uses the equation

5 = |8 – x| to find the maximum and minimum values.

We solve the equation for x.

$5 = |8 - x|$

By the definition of the absolute value function, we must have:

$- 5 = 8 - x \: or \: 5 = 8 - x$

We subtract 8 from both sides to get:

$- 5 - 8 = - x \: or \: 5 - 8 = - x$

$- 13 = - x \: or \: - 3 = - x$

This simplifies to:

$13 = x \: or \: 3 = x$

Therefore the minimum value is 3 and maximum is 13

Find the midpoint of the line using the midpoint formula.<br> Midpoint of AB:______

dimaraw [331]

Answer: MP=(1,1)

Step-by-step explanation:

$MP= (\frac{x_1+x_2}{2})(\frac{y_1+y_2}{2})$

$MP= (\frac{-2+4}{2})(\frac{-3+5}{2})$ -2+4=2 -3+5=2

$MP= (\frac{2}{2})(\frac{2}{2})$ 2/2=1

$MP= (1,1)$

How do i calculate the first quartile and the third quartile??? <br> !!!please help!!!

diamong [38]

Answer: The Median: 78, The First Quartile: 63, and The Third Quartile: 99

Step-by-step explanation: Ok, so let's put the data set from least to greatest....

(63, 63, 76,) (77, 79,) (84, 99, 99)

First Quartile Third Quartile

First, let's find the median, since you made a little mistake...

77 + 79 = 156

156 ÷ 2 = 78

The median is 78!

Now, let's determine the first quartile and the third quartile.

For the the first quartile/third quartile it'll be the middle number, if it's even we'll do the same extra step just like we'll do for the median. In this case it's not even therefore...

First Quartile: 63

Third Quartile: 99

I hope this helps!
