Tracie rides the bus home from school each day. The graph represents her distance from home relative to the number of minutes si

nce the bus left the school.
A coordinate plane showing Driving Home. The x-axis shows Time in minutes and the y-axis shows Distance from Home in miles. The line starts at (0, 9) and passes through (2, 8), (4, 7), and ends at (10, 4).
What does the slope of the graph mean?

Tracie’s bus travels towards her home at an average speed of StartFraction one-half EndFraction mile per minute.
Tracie’s bus travels towards her home at an average speed of 2 miles per minute.
Tracie’s bus travels away from her home at an average speed of StartFraction one-half EndFraction mile per minute.

The area of Kamila’s rectangular living room is 2.5 times the area of her square bedroom. The length of the living room is 18 fe
Archy [21]
Let L be the length of one side of Kamila's bedroom (since her bedroom is square, the area would be L x L). Then the width of her living room is 1.25L. So:
18*1.25L=2.5(L)²
22.5L=2.5L²
L=22.5/2.5=9
Kamila's bedroom is 9'x9'; her living room is 11.25'x18'. ☺☺☺☺

What is the slope of the segment shown for a staircase with 10-inch treads and 7.75-inch risers? As you walk up (or down) the st
s2008m [1.1K]

The formula for slope is

Slope = Rise / Run = Risers / Treads

Slope = 7.75 in /10 in = 0.775

The slope Is 0.775.

The vertical distance is not continuous, thus it is discrete. A discrete function only allows certain points in the interval. When you walk up or down the stairs, the vertical distances are not continuous because of the treads. You cannot stay also mid-air, so it should be discrete. An example of a continuous function would be when you walk up or down an inclined plane.

A local library claims it has 2.73x103 books. If there are 42 people in the building, how many books per capita are there?
sveticcg [70]

Answer:

Per\ Capita = 64

Step-by-step explanation:

Given

Books = 2.7  * 10^3

People = 42

Required

Determine the per capita

The per capita is calculated by dividing number of books by people as follows;

Per\ Capita = \frac{Books}{People}

Substitute 2.7 * 10^3 for books and 42 for people

Per\ Capita = \frac{2.7 * 10^3}{42}

Per\ Capita = 64 (Approximated)

<em>Hence, the per capita is 64</em>

A person who weighs 200 pounds on earth would weigh about 32 pounds on the moon. Find the weight of a person on earth who would
nadya68 [22]
Weight is the mass of the object * the acceleration due to gravity, so if the gravity changes the weight changes.
Thus, you want to put the situational data on their own, so the ratios you want to set up is:
\frac{M \ weight1}{M \ weight2} = \frac{E \ weight1}{E \ weight2}\\&#10;\frac{32lb}{15lb}=\frac{200lb}{x}\\&#10;32*x=200lb*15lb\\&#10;x=93.75lb
So a person that weighs 15 pounds on the moon weighs 93.75 pounds on Earth.

Mindy's dog, Rex, weighed 80 pounds a year ago. Now he weighs 92 pounds. What is the percent increase in his weight?
nadya68 [22]

Answer:

15%

Step-by-step explanation:

To find the percent increase, use the equation:

percent of increase=<u>amount of increase</u>

                                     original amount

The amount of increase is 92-80 = 12.  The original amount of 80; this gives us

12/80 = 0.15 = 15%
