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?
Answers
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.
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
Answers
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
There are 1,000 meters in 1 kilometer. How many kilometers are in 3,600 meters?
HELP
Answers
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.
Answers
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.

Answers
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

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.

C. 45
D. 85
Thank you.
Answers
Answer:
B. 40
Step-by-step explanation:
We know that the large angle is 90 degrees as it is a right angle. Thus, [tex]10+2x=90[/tex] (I don't know how to include degree symbols). We solve: [tex]2x=80[/tex], so then [tex]x=40[/tex]. Thus, x is forty degrees and the answer is B.
Answer:
40
Step-by-step explanation:
There is a bisector splitting a 90-degree angle into 2 parts, we are given that one of them is 10. This can only mean the other side is 80 degrees in total.
and 80/2 is 40

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
Answers
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.

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.
