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]

Answer:

I think it is B

Step-by-step explanation:

mark me brainliest

B) 9ft

The area of a square is us found by taking the length of a side and squaring it. For example, if 9 is the side length, we would find the area by doing 9^2 or 9 x 9. This gives us 81 which is the closest to 76.5.

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.

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.

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

Read the excerpt from the article Amazing Plants:What's for Dinner?There are a surprising number of plants that are carnivorous, or feed on meat. One of the most well-known carnivorous plants is the Venus flytrap. This carnivore lives in warm, swampy areas where it feeds on flies and any other insect unfortunate enough to land on one of its round, spiky leaves. The leaves are motion-sensitive, and the slightest touch causes a leaf to snap shut, trapping the prey behind a prison of spikes.Pitcher plants are another quiet carnivore. The plants are long, pitcher-like tube shapes, with wide bottoms full of water to catch and digest their prey. Pitcher plants use different strategies to attract prey. Some give off sweet smells, while others produce nectar. Pitchers have been known to consume anything from insects to small lizards and rodents.Read the article Trapped by a Predator:When I was 12, I went on vacation to the Wilmington, North Carolina area. While there, my family and I went on a hike in the Croatan National Forest, a true coastal forest that is bordered on three sides by water. As I traversed the boardwalk, I caught a glimpse of something pink in my peripheral vision. I stopped and bent down to inspect the mysterious looking specimen. It had long, sharp-looking white teeth and a large, pink mouth. Upon closer inspection, I noticed little droplets of liquid around the rim. Inside its mouth, there were six tiny hairs, three on the top and three on the bottom. While I was examining the unknown object, I saw a fly zoom in and land inside the mouth. I observed as it wandered around the reddish-pink, fleshy surface and brushed against one of the hairs. What happened next seemed like something out of a horror story. All of a sudden, the mouth snapped shut, and the teeth made a prison, trapping the poor fly inside. I witnessed the fly fighting against the spiky teeth, trying to escape, but it was an unsuccessful struggle. When my mother caught up to me on the path, I showed her the slayer, and she explained that the fly eater was the plant called a Venus flytrap. In that moment, I wanted to learn more about this carnivorous flora.I became a botanist because of that first encounter with the predatory plant. Over the years, I learned so much more about the Dionaea muscipula, better known as the Venus flytrap. For example, the liquid around the rim of its "mouth" is actually a sweet nectar that lures prey. In addition, the six tiny hairs, called trichomes, are like little sensory time bombs. This means when an insect touches a trichome, a timer is set for 20 seconds. If there is a second touch within the 20-second period, the mouth clamps down and traps the prey. The third movement signals the plant's digestive juices to start breaking down the insect. In about ten days, the Venus flytrap reopens and any part of the insect that didn't get digested falls out. It is an amazing process!Because of my experience in North Carolina all those years ago, I decided to become a botanist and specialize in carnivorous plants. I have studied pitcher plants, sundews, water wheels, cobra lilies, and more. I never bore learning about the different traps, like suction traps and sticky traps, that carnivorous plants use to snare their prey. In fact, you could say I was trapped by the Venus flytrap, that meat-eating predator, when I first laid eyes on it.Select the sentence that correctly combines information from both texts.
