Explanation:

This tent is a triangular prism. We have two congruent triangles in front and back. Let's stand the triangular prism up so that the triangle forms the base, or floor, of this figure.

The area of the base triangle is 5*4/2 = 20/2 = 10 square feet. I used the formula base*height/2 to get the area of a triangle.

Once we know the area of the base of the prism, we multiply that by the height of the prism, which is the 8 ft. So we get 10*8 = 80 cubic feet of volume.

Answer:

x = 1 y = -3 (1, -3)

Step-by-step explanation:

Use the Substitution Method

First, you have to turn the equations into slope intercept form (y = mx + b)

First equation

x - y = 4

subtract x from both sides

-y = -x + 4

divide each side by -1

y = x - 4

Second Equation

4x + y = 1

subtract 4x from both sides

y = -4x + 1

Turn the two new equations into one equation like so

-4x + 1 = x - 4

add 4x to both sides

1 = 5x - 4

add 4 to both sides

5 = 5x

divide each side by 5

x = 1

Fill in x in one of the original equations in order to find the value of y

4(1) + y = 1

4 + y = 1

subtract 4 from both sides

y = -3

The solution is (1, -3)

hope this helps :)

(b)The perimeter of a rectangular painting is 374 cm. If the width of the painting is 88cm, what is its length?

Answers

Answer:

part a is 54 part b is 99

Step-by-step explanation:

72 x ? =3888

x=54

374 is the perimeter. You have a side that is 88cm so the opposite side will be 88 cm as well. 374-176=198

so between the last 2 sides we have 198. The sides will be equal so you just divide it by 2

so the top and bottom of the rectangle are 99 and both sides are 88

Charlotte and Riley walked 6/10 of a mile to school one day, and then after school they walked 3/8 of a mile to the store. From the store back home was another 2/5 of a mile. How far did the girls walk in all?

Answers

Answer: The girls walked [tex]1\dfrac38[/tex] miles.

Step-by-step explanation:

Given: Distance from home to school = [tex]\dfrac{6}{10}[/tex] mile

Distance from school to store = [tex]\dfrac38[/tex] mile

Distance from store to home = [tex]\dfrac25[/tex] miles

Total distance = [tex]\dfrac6{10}+\dfrac38+\dfrac25[/tex]

= [tex]\dfrac{6\times4+3\times5+2\times8}{40}[/tex] [L.C.M.(10,8,5)=40]

= [tex]\dfrac{24+15+16}{40}[/tex]

= [tex]\dfrac{55}{40}[/tex]

= [tex]\dfrac{11}{8}=1\dfrac38[/tex] miles

Hence, The girls walked [tex]1\dfrac38[/tex] miles.

It's a great word that conjures visions of slime and unpleasantness. It is perhaps the most annoying part of having a cold or allergies. Mucus, however, plays a very important role in defense of our bodies and our health. In fact, it's high time mucus got a lot more respect.First, there are some amazing facts about mucus that are worthy of respect. Humans produce about a liter of mucus every day, whether they are sick or not. Bony fish and some invertebrates (snails or slugs) also have mucus cells on the outside of their body. This external mucus creates a protective coating that prevents predators' toxins from doing harm. Humans produce mucus to protect our stomachs, our lungs, and several other systems.We tend to not like mucus because it is a considered a symptom or sign that something is wrong. We usually only see it when we are sick, and so we tend to dislike it. According to Michael M. Johns, III, MD, however, "mucus is incredibly important for our bodies." Johns, an assistant professor at Emory University, calls mucus "the oil in the engine" of our bodies. Without mucus, our engines, or bodies, would freeze up and stop working properly.Furthermore, mucus is not just the nasty gunk you see when you are sick. It lines the tissues in your mouth, your nose, throat, and lungs. It also is crucial in protecting your digestive system. Mucus puts a protective coating over the surfaces of these tissues, keeping them moist. Most of the time we don't notice mucus is making our lives better. It does its job quietly, making everything run smoothly, keeping our inner tissues soft and flexible enough to fight off invaders.Occasionally, though our mucus-making membranes go into overdrive. If you eat a hot pepper, your mucus membranes in your mouth and throat start producing extra mucus to protect you. If you come into contact with pollen, you may get a runny nose and start sneezing and coughing. When these things happen, your mucus systems start making more fluids to wash away the irritating particles. Mucus also has some antibodies that increase our ability to fight off bacteria and viruses.It's hard to appreciate what is essentially slime, but we have mucus for some very good reasons. It helps to keep us healthy and lets us know when our bodies are under attack. We would be wise to respect what our bodies do to keep us safe. So the next time you find yourself reaching for a tissue, remember mucus is your friend and ally.What's in a Name?Mucus is a great word, not only because it gives name to an important bodily function, but also because it is one of those words that simultaneously makes you feel grossed-out and giggly. Other words for this powerfully important human-health tool include slime and phlegm. Slang words for mucus include boogers and snot. All of these words have the same giggle-power, simply from the combination of consonants and vowels. By the way, mucus is an old word; it's been around since the mid-1600s and has roots back to Latin (mucere, to be moldy or musty) and Greek (myxa, mucus). While you may assume that words like snot and boogers are relatively new slang terms, they are not. Snot dates to 1560 and comes from an Old English word, gesnot, and has the same root as the word snout. The word booger is not quite as old but has been in use since the 1890s.The authors of both texts would most likely agree that A. mucus is gross but important B. the names of things can be funny C. slime and mucus are the same thing D. words for mucus have interesting histories Given line 1, with coordinates (-7,-3) and (4,7), and line2 with coordinates (7,-7) and (-3, 4), find the slope of line 2 Who wants brainlist and extra points plz help me thisWhat title should this story be????In 1773, The girl was named Jess the only child of her honored family, she was 12 years old and she looked like her mother.

Jess doesnt want to go to school, unless the war is over because she keeps thinking How will the war end?. So she kept asking them and they told her that we will win no matter what. But she wont believe it until she sees it, Jess wants to go to school but how will she go?

So she asked Benjamin Franklin that if they could stop the tea party , he was involved in the tea party. But Franklin told her We do not want violence but they asked for it, little girl. There was tea involved, but nobody was drinking it. The Boston Tea Party was a protest by the American Colonists against the British government. So Jess was mad and she did not know why they were arguing about that. So she went to the other side and told them, ``Why do you argue about this?''. That vice captain told the captain that she is from the other side, and the captain got mad. The captain got mad, and he asked her What do you want?. She was not scared and replied I want you to stop going against the tea party, I want to go to school. HAHAHAHAHAHAHA said the leader laughing out loud that he cried of laughter. What can a little girl like you do against us? said the leader. She said As many as you can, What?. Don't you dare talk back to you said the leader. The captain was serious, and told the mens to kick her out now!When the captain told the mens to kick her out, she was so mad and then she did something that she was not supposed to do as a kid at her age. She burned their base and then she ran away. Almost 30-40 people died and the rest survived including the captain. The other team saw the fire and they thought it was an accident made by them and they attacked. So after they won and named it the boston tea party after their victory. They were also told they had to pay high taxes on the tea. This tax was called the Tea Act. It actually was a lot of tea. The 342 containers totaled 90,000 pounds of tea!
