The correct statements on the graph of time and calories is:
The graph is proportional because it is a straight line going through the origin.The constant of proportionality is 10 calories per minute.When is a graph proportional ?When two numbers are multiplied or divided, there is a proportionate relationship. Although a linear equation frequently includes a proportional component in addition to some constant number, a linear relationship can also be proportional.
A relationship is proportionate if its graph is a line or ray that passes through the origin. It is not proportionate if the line or ray does not go through the origin. Additionally, something is not proportionate if it is not linear.
As shown in the graph, the straight line passed through the origin which means that it is a proportional relationship.
The constant of proportionality in this case is therefore:
= Calories at a minute / Minute
= 20 / 2 minutes
= 10 calories per minute

What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the given question
35mm represents 10m
⇒ 1m = 35/10
⇒ 1m = 3.5mm
Therefore,
The actual length of the room on the blueprint = 3.5 × 9 = 31.5mm

what’s the slope of the line? i’m marking a brainliest!
Answer:
m = -2
Step-by-step explanation:
To get the slope of the line, we are going to use the 2-points slope equation form
That will be;
m = (y2-y1)/(x2-x1)
(x1,y1) = (-5,11)
(x2,y2) = (8,-15)
m = (-15-11)/(8-(-5)) = -26/13 = -2
The possible mistake she might have made is placing the x-values difference over the y and her formula will look like;
m = (x2-x1)/(y2-y1)
It is an error of switching the numerator for the denominator

Labor rate: $8.75 per hour.
Hours worked: 16
Total price of services: $224
Overhead rate: %
Answer:
37.5%
Step-by-step explanation:
Labor rate = 8.75 dollars per hour.
Hours worked = 6
Direct cost of labor = 140 dollars
Total price of services = 224 dollars
Therefore, the overheads = 84 dollars which is
84 X 100 / 224 = 37.5%
[tex]Which point is closer to the line y=1/2x+4, A(-2,6) or B (4,3)?[/tex]
9514 1404 393
Answer:
neither; they are the same distance from the line
Step-by-step explanation:
The distance of point (x, y) from line ax+by+c=0 is given by ...
d = |ax +by +c|/(√a² +b²)
Since we're using the same line for both points, we only need to evaluate ...
d = |ax +by +c|
Subtracting y can put the equation in the desired form:
1/2x -y +4 = 0
__
For point A, the expression of interest evaluates to ...
|(1/2)(-2) -(6) +4| = |-1-6+4| = 3
For point B, the expression of interest evaluates to ...
|(1/2)(4) -(3) +4| = |2-3+4| = 3
These values tell us the points are the same distance from the line.
_____
The attached graph shows that circles of the same radius centered on A and B are both tangent to the line. Hence the distances are the same.

Step-by-step explanation:
if the diagonal of the square is 8 feet what is the area of the square
Answer:
32
Step-by-step explanation:
You have to use pythagorean theorem for this, where a and b represent the 2 sides while c represents the hypoteneuse.
a²+b²=c²
If the diagonal of a square is 8, it divides the square into 2 triangles, both with a hypoteneuse of 8. Since it is a square, that means the other 2 sides will have equal lengths. So input 8 into the equation:
a²+b²=8²
a²+b²=64
Then you can change a and b into the same variable, since you know they will be equal due to you working with a square.
a²+a²=64
simplify: 2a²=64
divide both sides by 2: a²= 32
square root both sides: a = [tex]\sqrt{32}[/tex]
then you know the length of each side is [tex]\sqrt{32}[/tex]
to find the area of a square, you must multiply both sides by each other, so do [tex]\sqrt{32}[/tex]*[tex]\sqrt{32}[/tex], which will give you 32 since you are essentially doing this:
[tex](\sqrt{32})^2[/tex] in which the square and square root cancel out.
Nathan launches a water balloon vertically from a platform on his roof. The height of the balloon (in feet) is represented by the equation h=−16t2+28.7t+32.4, where t is the time (in seconds) after he launches the water balloon. What is the maximum height of the balloon?
Answer:
45.27feet
Step-by-step explanation:
Given the height of the balloon (in feet) represented by the equation h=−16t2+28.7t+32.4, where t is the time (in seconds)
Note that the velocity of the balloon at maximum height is zero, hence;
v = dh/dt =0
-32t+28.7 = 0
-32t = -28.7
t = 28.7/32
t = 0.897secs
Get the maximum height
Recall that h=−16t²+28.7t+32.4
h = -16(0.897)²+28.7(0.897)+32.4
h= -12.87+25.74+32.4
h = 45.27feet
Hence the maximum height reached is 45.27feet

Answer:
54.5%
Step-by-step explanation:
Given data
Cost price= $15
Selling price= $33
Mark up percent =????
%markup= selling-cost/selling*100
substitute
%markup= 33-15/33*100
%markup= 18/33*100

A store wants employees to start wearing uniforms to work. The plans to purchase the uniforms and hand out 5 uniforms to every employee one for each day or the week. Uniforms come in packs of 8, and the store plans to purchase 56 packs of uniforms. How many employees can the store give uniforms to?
Answer:
89 employees
Step-by-step explanation:
Uniforms come in packs of 8, and the store plans to purchase 56 packs of uniforms.
This means
1 pack = 8 uniforms
56 packs = x uniforms
Cross Multiply
x = 56 × 8 uniforms
x = 448 uniforms
The plan is to hand out 5 uniforms to every employee one for each day or the week.
Hence, the number of employees that the store can give can uniforms to is calculated as:
5 uniforms = 1 employee
448 uniforms = x employees
Cross Multiply
5x = 448 × 1 employee
x = 448/5
x = 89.6 employees.
Since a person cannot be represented by decimal, the store can give uniforms to 89 employees

To find,
The value of x.
Solution,
We have,
