A teacher grades 27 tests in 3 hours Find the constant of variation
Answer:
9Step-by-step explanation:
Step one:
given
Let the number of tests graded be g = 27
time taken t = 3 hours
Required
The constant relating the time and the number of tests
Step two:
"The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another."
so that the direct variation is
g∝kt
g=t/k
k= g/t
k=27/3
k=9
Answer:
9
Step-by-step explanation:
Since you know that there are 27 tests every three hours then you can divide 27 by 3 to get the constant variation or "test per hour". So then, 27 divided by 3 is 9.
3$ pre child 5$ adult totaling 374 tickets sold at the cost of 1524 dollars. how many child and adult tickets were sold
Answer:
173 children tickets were sold and 201 adult tickets were sold
Step-by-step explanation:
Let the number of child ticket sold be x
Let the number of adult ticket sold be y
If the total number of ticket sold is 374, hence;
x +y = 374 .... 1
Also if the ticket cost 3$ per child and 5$ per adult with total cost of $1524, this can be expressed as;
3x + 5y = 1524..... 2
Solve both equations simultaneously
From 1; x = 374 - y ...3
Substitute equation 3 into 2
3(374-y)+5y = 1524
1122-3y+5y = 1524
1122+2y = 1524
2y = 1524 - 1122
2y = 402
y = 402/2
y = 201
Since x = 374-7
x = 374 - 201
x = 173
Hence 173 children tickets were sold and 201 adult tickets were sold
factor the expression
6x + 24 =

Biking at 10 mph, it takes Kristen 1/2 hour to reach the train station to go to work. Kristen then takes the train to work, and it takes another 1/2 hour for her to get to work when the train travels 24 mph. How far does Kristen travel to work?
A.
65 miles
B.
27 miles
C.
17 miles
D.
16 miles
Answer:
speed = Distance /Time
10 mph = Distance / 0.5 hours
distance = 10 * 0.5
Distance = 5 miles
speed = Distance /Time
24 mph = Distance /0.5 hours
Distance = 24 * 0.5
Distance = 12 miles
Total distance = 5miles + 12miles
= 17miles

While on a trip, you notice that the video screen on the airplane, in addition to showing movies and news, records your altitude (in kilometers) above the ground.
As the plane starts its descent
(at time x = 0), you record the following data: Time, x (min.) Altitude, y (km)
12 0 10 8 16 16 18 4 110 12
If you were to graph these points on a graph, you would notice that the line that forms represents a linear function. What is the practical meaning of slope in this situation?
a. For every minute that passes, the airplane descends 1 kilometer.
b. For every minute that passes, the airplane ascends 1 kilometer.
c. For every 2 minutes that passes, the airplane descents 1 kilometer.
d. For every minute that passes, the airplane ascends 2 kilometers. C.

How to find the rate of change of a linear equation?Suppose that the considered linear equation is of the form
y=mx+c
Then, when we change x by 1 unit, then:
The rate of change is the slope. The formula for slope is
m = y2 - y1 / x2 - x1
Using the first two points, (0, 12) and (2, 10), we have
m = (10-12)/(2-0)
m = -2/2
m = -1
This means the plane descends 1 km per minute which means in 3 minutes' time, the plane descends 3 km.
Therefore, option a. For every minute that passes, the airplane descends 1 kilometer.

Swings:
residents
Sandbox: residents
Obstacle course: residents
Answer:
swings: 120 (50%)
obstacle course: 80 (1/3)
sandbox: 40
Step-by-step explanation:
we know by looking, that swings makes up 50%, so we divide 240 by 2 to get 120
the obstacle course makes up one-third, 1/3 of 240 is 80
add 120+80 to get 200
to find the sandbox amount, do 240 minus 200 and we get 40
The circle graph is used to show how variables measure against one another using a circle of different sectors.
There are 40 residents in sandbox, 80 in obstacle course, and 120 in the swings
The number of residents is given as:
[tex]n = 240[/tex]
From the given circle graph, we have the following proportions
[tex]Sandbox = 1/6n[/tex]
[tex]Obstacle = 1/3n[/tex]
[tex]Swings= 1/2n[/tex]
So, the number of residents in each equipment is:
[tex]Sandbox = \frac 16 \times 240[/tex]
[tex]Sandbox = 40[/tex]
[tex]Obstacle = \frac 13 \times 240[/tex]
[tex]Obstacle = 80[/tex]
[tex]Swings =\frac 12 \times 240[/tex]
[tex]Swings =120[/tex]
Hence, there are 40 residents in sandbox, 80 in obstacle course, and 120 in the swings
