A group of students is timed while sprinting 100 meters. Each student’s speed can be found by dividing 100 m by their time. Is each statement true or false?
Select the correct choice for each statement then explain your reasoning.
1. Speed is a function of time.
2. Time is a function of distance.
3. Speed is a function of number of students racing.
4. Time is a function of speed.
Answer:
The true statements are (a) and (d)
Step-by-step explanation:
(a). Speed is a function of time : As seen from equation (1) Speed of the students varies according to the value of time. So, This a true statement.
(b). Time is a function of distance : Distance is not varying in the equation (1), it is fixed to be 100. So, time is not a function of distance because here the distance is made constant. So, This is false statement.
(c). Speed is a function of number of students racing : Speed is not depending on the number of students racing so sped is independent of the number of the students racing. Therefore, Speed is not a function of number of students racing. This is False statement.
(d). Time is a function of speed : As seen from equation (1) Time of the students varies according to the value of their speed. So, This a true statement.
The true statements are (a) and (d).

Answer:
10 5/6
Step-by-step explanation:
The value of a share of stock decreases in value at a rate of $1.40 per hour during the first 3.5 hours of trading. Enter and solve an equation to find the decrease in the value of the share of stock during that time. Let x represent the decrease in value of the share of stock during 3.5 hours.
The equation to find the decrease in the value of the share of stock is x / _____ = _______
The decrease in value of the share of stock during 3.5 hours was $________
Answer:
x/3.5h = -$1.4
So, x = -$1.4 * 3.5h
= -$4.9
Step-by-step explanation:
Since your losing $1.4 every hour, the 1.4 is supposed to negative.
Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours
and get -$4.9.
An irregular polygon is shown below:
The area of the irregular polygon is ____ square units.
Answer:
26 Units Squared
Step-by-step explanation:
We can split the polygon into different sections the first section 4 units * 4 units = 16 units squared then by analyzing the other section we can find it is 5 units by 2 units = 10 units added together is 26 Units Squared

Answer:
Length = 11 1/3 ft; Width = 4 2/3 ft
Step-by-step explanation:
First question:
The length is 2 more than twice the width, so
L = 2W + 2
Second question:
2L + 2W = 32
L = 2W + 2
Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.
2L + 2W = 32
2(2W + 2) + 2W = 32
4W + 4 + 2W = 32
6W = 28
W = 28/6 = 14/3 = 4 2/3
L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3
L = 11 1/3
W = 4 2/3
Answer: Length = 11 1/3 ft; Width = 4 2/3 ft

Answer:
The first option is correct, 12/30 and 25/30
Step-by-step explanation:
To get common denominators, you need to find the GFC (greatest common factor) of 5 and 6, which is 30. Then you would need to make the fractions equal the same as the original fractions, by multiplying.
2/5 = ?/30 <- you can see that 30 is 6 times more than 5. so this means you multiply 2 by 6 to get 12. 12/30
5/6 = ?/30 <- you can see that 30 is 5 times more than 6. so this means you multiply 5 by 5 to get 25. 25/30

Answer:
c is correct
Step-by-step explanation:
A line passes through the point (2,-6) and has an initial value of 6. What is the rate of change for this line?
A. -12
B. -6
C. -1/6
D. 6
-6
We assume "initial value" means the y-intercept is (0, 6). The rate of change is the "rise" divided by the "run" between the two points.
rise = -6 -6 = -12 . . . . difference of y-values
run = 2 -0 = 2 . . . . . . difference of corresponding x-values
rate of change = rise/run = -12/2 = -6
The rate of change of this line is -6.

Determine whether the representation is proportional.y= -9x
Answer:
Yes it is
Step-by-step explanation:
y=-9x means that for every x value, the y value decreases by 9, so it is proportional because the value of y decreases the same amount each time. For example, if x=1, y=-9. If x=5, y=-45, and so on.
