Answer:

3 cm

Step-by-step explanation:

[tex]V_{cylinder} = 189\pi \: cm^3[/tex] (Given)

[tex]h_{cylinder} = 21\: cm[/tex] (Given)

Formula for [tex]V_{cylinder}[/tex] is given as:

[tex]V_{cylinder} = \pi r^2h[/tex]

[tex]\implies 189\pi = \pi r^2(21)[/tex]

[tex]\implies \frac{ 189\pi}{21\pi} = r^2[/tex]

[tex]\implies 9 = r^2[/tex]

[tex]\implies \pm\sqrt 9 = r[/tex]

[tex]\implies \pm 3 = r[/tex]

Length of radius can not negative

[tex]\implies r = 3 \: cm[/tex]

Construct a scatter plot of these data using the following coordinate grid. The vertical axis represents the calories and the horizontal axis represents the fat (grams).

Answers

Answer: here is a lesson that helped me Discussion Points and Possible Answers

1. The table below shows the total fat in grams and total calories for various fast food items. Does this

data suggest that there is an association between the fat grams and total calories in fast food

items? Support your answer.

Sandwich Total fat (g) Total Calories

Hamburger 9 260

Cheeseburger 13 320

Quarter Pounder 21 420

Quarter Pounder with Cheese 30 530

Big Mac 31 560

Arch Sandwich Special 31 550

Arch Special with Bacon 34 590

Crispy Chicken 25 500

Fish Fillet 28 560

Grilled Chicken 20 440

Grilled Chicken Light 5 300

Sample Answers: The food items with more fat tend to have more calories, so it seems

reasonable that there is a positive association. Larger values of total fat tend to go with larger

values of total calories.

2. A scatter plot can be used to visualize the association between fat and calories. Think about how

the variables are related, and how the variables fat and calories should be placed on the

coordinate axes. Label the axes on the graph below, and explain your choice of axes and

variables.

Answer: Since the amount of fat in fast food affects the

total calories, the variable fat is the independent

variable. This variable is best to plot along the horizontal

axis. The variable calories is the dependent variable

and is, therefore, best to plot along the vertical axis.

Teacher Tip: Discuss with the students why fat is the independent variable

and calories is the dependent variable in this situation. Ask them whether

the amount of fat depends on how many calories are in the food, or the

amount of calories depend on how much fat is in the food.

(Find The Probability Question)

Choose 2 apples to eat from a bowl containing 6 apples, 8 oranges, and 4 bananas.

Answers

Answer:

240/990 = 8/33.

Step-by-step explanation:

Arbitrarily, the chances of this outcome, by picking an apple first, then an orange, then a banana, is:

5/11 × 4/10 × 2/9= 40/990

But we don't care about the order and in reality, there are six orders that would achieve our outcome:

Apple, orange, banana

Apple, banana, orange

Orange, Apple, banana

Orange, banana, Apple

Banana, Apple, orange

Banana, orange, Apple

The probability of each these outcomes is the same as computed above (Just exchanging numerators.) So the answer is 6×(40/990)

The answer is 8/33 since you do 6/20 times 6/20 which is 36/400 which simplifies to 8/33

Which expression is equivalent to 30x - 12y

10(3x + 2y)

6(5x + 2y)

6(5x - 2y)

10(3x - 2y)

Answers

6(5x - 2y) is the correct answer / third answer

Answer:

B) 6(5x -2y)

Step-by-step explanation:

When we have a number outside the parenthesis, we can distribute this number to all the terms inside the parenthesis. Since our given expression is 30x -12y, we are looking for an expression that when expanded results in these two numbers.

Only option B provides both 30x and -12y, as seen as 6 times 5x= 30x and 6 times -2y = -12y.

Peter made a square pin for his pet guinea pig to roam in. One side was 18.2 cm. What is the area of the pin?
A. 331.24 cm
B. 321.24 cm
C. 74.8 cm
D. 72.8 cm

Answers

Hi!

Answer:

A) 331.24

Step-by-step explanation:

To find the area, you need to multiply LxW, (Length x Width) and in this case, since it's a square, the sides are equal. Each side is 18.2 cm, so all we have to do is multiply 18.2 by 18.2, and then we get 331.24, so your answer is option A.

I hope this helps! :)

It’s A since 18.2*18.2=331.24
