Step-by-step explanation:

cylinder volume equation: v=[tex]\pi[/tex][tex]r^{2}[/tex]h

Water heater x= [tex]\pi[/tex](8.5)^2 x 48= 10895.04

Water heater y= [tex]\pi[/tex] (9.5)^2 x 44= 12475.26

Water heater z= [tex]\pi[/tex] (10.5)^2 x 32= 11083.54

A is false because water heater Y has the greatest volume

B is false because all the volume are different

C is false because z has the smallest volume

What is the area of the shaded region?

Answers

Answer:

area 91

Step-by-step explanation:

area= 1/2 b×h

base is 13 hight 14 times and its 91

Answer:

59 inches²

Step-by-step explanation:

area of large triangle: (14 × 13) ÷ 2 = 91 inches²

area of small triangle: (8 × 8) ÷ 2 = 32 inches²

91 - 32 = 59 inches²

From the set {37, 50, 63}, use substitution to determine which value of x makes the inequality true.
[tex]x - 13 > 37[/tex]

A. 50

B. 37

C. 63

D. none of these

Answers

50 - 37 = 37 (doesn’t make the inequality true, since it equals 37)

37 - 13 = 24 (doesn’t make the inequality true since it’s less than 37)

63 - 13 = 50 (this is correct because your answer is greater than 37)

Answer: C

37-13 is less than 37 50-13 is equal too 37 so c is the answer

Three semicircles are placed in a rectangle, as shown below. The length of the rectangle is 72m. Find the area of the shaded region. Use the value 3.14 for pi , and do not round your answer. Be sure to include the correct unit in your answer.

Answers

Step-by-step explanation:

Width of rectangle = 7 cm

because ∵ width of rectangle is equal to the radius of each semicircle.

therefore ∴ radius of each semicircle (r) = 7 cm.

therefore ∴ Diameter of each semicircle = 14 cm

therefore ∴ Length of rectangle = 3 x 14 = 42 cm.

Answer:

63.21cm'2

Please! Mark me as brainliest please.

Your answer is 1049.76

72 divided by 3= 24, 24 is your diameter of each semi circle

To find the area of your semi circles you’ll use pi times radius squared.

Aka 3.14 times 12^2 divided by 2 = 226.08

Times 3 for 3 semi circles

226.08 times 3= 678.24

Now find the area of the rectangle and you get the height from the semi circles which is 24m

72 times 24= 1,728m^2

Now you take the area of the rectangle and subtract the area of the circles

1,728 - 678.24 = 1,049.76m

Out of the 25 students in Mrs. Coulter's class, 15 are girls. In the school there are 390 boys. If the ratio of boys to students in Mrs. Coulter's class is proportional to the ratio of the number of boys in the school to the total number of students in the school, how many students are at the school?

Answers

Answer:

975 students

Step-by-step explanation:

This is a dense question. Let's look at it piece by piece:

1. The ratio of boys to students in the class is 10/25. If there are 25 students and 15 girls, that leaves 10 boys.

2. The question says that the ratio is in proportion of boys to total students in the school. "In proportion" in this case means that if we convert 10/25 to a fraction with numerator 390, the denominator is the amount of students in school.

3. 10x39=390. What you do the numerator you must do to the denominator: 25x39=975.

4. This means 975 students go to the school.

35% = 35/100
So 35/100*200 <- 200 is the number of all tags
When you do this, you’ll get 70
So 70 tags are blue

Next, to find how many yellow tags, just
3/8*200 = 75
There’s 75 yellow tags

If you add both amounts (70+75) you’ll get 145

Now we know there are 200 tags and 145 of them are yellow and blue, so the rest are red
200-145 =55

Answer:

55 name tags are red

Sarah bought a TV at a 15% discount. Later she found that there should have been a 20% discount, so the store gave her $17 back. What was the original price of the TV before it was discounted?

Answers

Answer:

Step-by-step explanation:

The store gave her back the difference (20%-15%= 5%)

5%= the $17 returned

100/5= 20

20*17= $340 which was the original price of the TV before discounts

the original price of the tv would be $340

What is the total height of all the plants?

Answers

Answer: 6 1/8

Step-by-step explanation:

1/8 x 2 = 1/8 x 2/1 = 2/8 = 1/4

1/4 x 3 = 1/4 x 3/1 = 3/4

3/8 x 4 = 3/8 x 4/1 = 12/8 = 1 4/8 = 1 1/2

1/2 x 3 = 1/2 x 3/1 = 3/2 = 1 1/2

5/8 x 1 = 5/8 x 1/1 = 5/8

3/4 x 2 = 3/4 x 2/1 = 6/4 = 1 2/4 = 1 1/2

Start with the big number first.

1 1/2 = 1 4/8

5/8 = 5/8

3/4 = 6/8

1/4 = 2/8

Add them all up.

1 4/8 + 1 4/8 = 2 8/8 = 3

3 + 1 4/8 = 4 4/8

4 4/8 + 5/8 = 4 9/8 = 5 1/8

5 1/8 + 6/8 = 5 7/8

5 7/8 + 2/8 = 5 9/8 = 6 1/8

But it turned out to be a big disappointment. Read the article "The Necessity of Hybrids". What do you get if you cross two different species? Depending upon the species, you might end up with a grolar bear, a wolfdog, or a Savannah cat, among many others. What do these animals have in common? They're hybrids. Sometimes hybrids happen naturally in the wild, but usually, hybrids are the result of humans selectively breeding animals. Grolar bears and pizzlies are the result of crossing polar bears and grizzly bears. These hybrids were first seen in zoos, as the bears' natural habitats did not normally overlap. Recently, these hybrids have started appearing in the wild. Due to climate change, the bears' once-separate habitats are beginning to overlap. Bigger and more aggressive than their parents, grolar bears and pizzlies could pose a risk to natural habitats and humans. Wolfdogs are, as their name suggests, the result of crossing a wolf with a domestic dog. Bred for the pet trade, these hybrids do not often happen in the wild. Wolfdogs do not make good pets, however, as they can be destructive and aggressive. Many states have outlawed keeping wolfdogs because they can pose a danger to people. Savannah cats are another example of human-made hybrids that were developed to be pets. Savannahs are the result of crossing a small wildcat called a serval with a domestic housecat. They look like miniature versions of the wildcat, which is why many people like keeping them as pets. Like the wolfdog, however, Savannahs do not make ideal house pets. They can be destructive, and usually, they keep the wild nature of the serval. There are many more examples of human-made hybrid animals. Some hybrids, such as the mule, have been helpful to humans. Unfortunately, others, like the wolfdog or Savannah cat, should not have been made in the first place. According to the text, why are bear hybrids being seen in the wild? Due to climate change, the bears' once-separate habitats are beginning to overlap. Grolar bears and pizzlies are the result of crossing polar bears and What is the most important people in your life?
