There are 1,000 meters in 1 kilometer. How many kilometers are in 3,600 meters?
HELP
Answer:
A. 3.6 kilometers
Step-by-step explanation:
1000 meters = 1 km
3600 meters = x km
Set as a ratio:
1000 : 1 = 3600 : x
Then divide:
[tex]\frac{3600}{1000} = \frac{x}{1} = x[/tex]
so 3600/1000 = 3.6 = x
3.6 km
The diameter of a wheel on a car is 16 inches. What is the circumference of the wheel? Use 3.14 for pi.
Answer:
The circumference is 50.24in.
Step-by-step explanation:
All you have to do is multiply the diameter by 3.14. Easy and so simple
The circumference of the given wheel is 50.24 inches.
What is the Circumference of a circle?The Circumference of a circle is defined as the product of the diameter of the circle and pi.
C = πd
where 'd' is the diameter of the circle
We have been given data as follows:
The diameter of the circle (d) = 16 cm
Circumference of the circle = πd
Substitute the values in the above formula and we get
Circumference of the circle = 3.14 × (16)
Apply the multiplication operation, and we get
Circumference of the circle = 50.24
Thus, the circumference of the given wheel is 50.24 inches.

Suppose that Violet is conducting a study to determine whether there is a relationship between the time a person spends running and the number of calories that he or she burns. She selects a random sample of 40 runners between the ages of 18 and 24 and records the time that each person ran and the number of calories that each person was able to burn while running. At the end of her study, she finds that people who were able to run for longer times burned more calories.
(a) What type of study is this? Briefly explain
(i) Experiment
(ii) Observational study
(iii) Survey
(b) What is the explanatory variable? Is it categorical or quantitative?
(c) What is the response variable? Is it categorical or quantitative?
(d) Which of the following is a potential lurking variable in this study? Defend your selection (i.e. explain why it is a lurking variable).
(i) the time each person ran
(ii) the number of calories each person burned
(iii) the age of the runners (iv) the speed at which each person ran
Answer:
A. observational
B. Time spent running
C. Calories burnt
D. Speed person ran
Step-by-step explanation:
A. This is an observational study as these selected runners are being observed but no experiment is being carried out
B. The explanatory variable or independent variable is the I'm the individuals spend running. This is quantitative.
C. The response variable Is the amount of calories that is being burnt. This is also quantitative.
D. The lurking variable is iv. It is the speed at which each person ran
Irene needs a total of $250 to buy a bicycle. She has already saved $70. If she saves $10 a
week from her earnings, what is the least number of weeks she must work to have enough
money to buy the bicycle?
Answer:
18 weeks
Step-by-step explanation:
250 - 70 = 180
180/10 = 18 weeks
Answer:
18 Weeks
Step-by-step explanation:
The least amount of weeks that Irene must work in order to buy the bike is 18. To find your answer, subtract $70 from $250. You will get $180. This is the amount of money that Irene still needs to earn. If she saves her money for 18 weeks, she will have her $180. This is because $180 divided by $10 is 18.

Identify if it's an independent or dependent event and write the probability as a fraction * What is the probability that from a normal 52 card deck, you randomly draw a 3, and then without replacing the 3, you draw the Queen of Hearts?
Answer: 0.151 percent
Step-by-step explanation:
The probability of any particular outcome is
(number of possible successful outcomes) / (number of total possibilities)
-- On the first draw, there are 52 possible total outcomes, and
only 4 that are successful ... drawing a 3 .
The probability of drawing a 3 from a full deck is ( 4 / 52 ).
-- On the second draw, there are 51 possible total outcomes (the first
card you drew stayed out), and only one is successful ... drawing the
queen of hearts.
The probability of this particular outcome is ( 1 / 51 ).
-- The probability of both of them is
( 4 / 52 ) x ( 1 / 51 ) =
( 4 / 2,652 ) = about 0.151 percent.

There are 48 students in a school play. The ratio of boys to girls is 5 : 7. How many more girls than boys are in the play?
Pls help me
Answer:
There are 8 more girls than boys.
Step-by-step explanation:
Ratios are easier to read as fractions (at least to me), so 5:7 would be 5/7. When you multiply both the top and the bottom by 4, you get 20/28, meaning that there are 20 boys and 28 girls. 28-20=8, so there are 8 more girls than boys.

Answer:
B They are similar, but not congruent.
Step-by-step explanation:
Reflection, rotation, and translation are "rigid" transformations. They result in congruent figures.
Dilation is not a rigid transformation. For any dilation scale factor other than 1, the figures will be different sizes, so will not be congruent. They will be similar. (Angles will be congruent, and lines/sides will be parallel.)
The combination of dilation (by 0.5) and reflection results in similar, but not congruent, figures.
Faye can sort 150 recyclable items in 3 minutes Based on the ratio shown how many recyclable items can Faye sort in 4 minutes?
Answer:
200 recyclable items
Step-by-step explanation:
The computation of the number of recyclable items would be sort in 4 minutes is shown below:
Given that
There is 150 recyclable items in 3 minutes
So in 4 minutes, the no of recyclable items is
= 150 × 4 ÷ 3
= 200 recyclable items
How do I simplify this
Answer:
96/18
Step-by-step explanation:
To simplify you need to turn it into an improper fraction. This means that the numerator (the number on top) is greater than the denominator (the number on the bottom). The improper fraction form of 5 6/18 is 96/18. I believe this is the answer to your question.
I hope this helps you!
Graphically, a point is a solution to a system of two inequalities if and only if the point
lies in the shaded region of the top inequality, but not in the shaded region of the bottom inequality.
lies in the shaded region of the battom inequality, but not in the shaded region of the top inequality.
lies in the shaded regions of both the top and bottom inequalities.
does not lie in the shaded region of the top or bottom inequalities.

Answer:
(c) lies in the shaded regions of both the top and bottom inequalities.
Step-by-step explanation:
A point that is a solution to the system must be a solution to all of the inequalities in the system. It must lie in the shaded regions of both.

Solve the system of equations using the linear combination method.

Enter your answers in the boxes.
X
Y
Answer: x = -3; y = -8
Step-by-step explanation:
Multiply second equation by -1 and add to first equation. The y term zeros out, leaving you with -3x = 9, so x = -3.
Then go back and sub -3 in for x in either equation, and solve for y. If you use the first equation, you get 4(-3) -3y = 12
-12 -3y = 12
-3y = 24
y = -8

C-3d = 11
-2c + 3d = -16
This looks like a system of equations:
We should solve for c on the first equation because we can substitute for c. There are a lot of ways we can do a system of equations, but I will do this.
c - 3d = 11
+3d +3d
c = 11 +3d
Now we can substitute.
-2(11+3d) + 3d = -16
solve
-22 + -6d + 3d = -16
-22 + -3d = -16
+22 +22
-3d = 6
/-3 /-3
d = -2
So we have found d. We can solve for c.
c - 3(-2) = 11
c + 6 = 11
-6 -6
c = 5
Now we know both D and C. d=-2 and c=5
