This question is bothering and hurting my brain a lot: A restaurant has a square floor with an area of 324 m². Sketch the resaurant floor. What are its dimensions?

Answers

Answer:

The dimensions are 18m by 18m

Step-by-step explanation:

Since the problem says the floor is square, we know that all 4 sides are equal. The area for a square is one side squared. Since we do not have the actual length per side, we write the following formula: x^2= 324.

From there, we simply take the square root to figure out that one side is 18 meters. Once we know one side, we know all 4 because a square has equal sides. Therefore, the dimensions of the floor are 18m x 18m. I hope this helps!

Answers

Answer:

Step-by-step explanation:

okay can someone please answer this>

Answers

Answer:

1st one: x = -2

2nd one: x = -4

Step-by-step explanation:

1. Step 1: Rewrite into an equation.

[tex](6x+44) + (-10x+65) = 117[/tex] [tex]6x + 44 - 10x + 65 = 117[/tex]

Step 2: Simplify both sides of the equation.

[tex](6x-10x) + (44+65) = 117[/tex] [tex]-4x + 109 = 117[/tex]

Step 3: Subtract 109 from both sides.

[tex]-4x + 109 - 109 = 117-109[/tex] [tex]-4x = 8[/tex]

Step 4: Divide both sides by -4.

[tex]\frac{-4x}{-4}=\frac{8}{-4}[/tex] [tex]x = -2[/tex]

Therefore, x = -2 for the first one.

2. Step 1: Rewrite into an equation.

[tex]-16x + 13 - 20x + 23 = 180[/tex]

Step 2: Simplify both sides of the equation.

[tex](-16x-20x)+(13+23)=180[/tex] [tex]-36x +36 = 180[/tex]

Step 3: Subtract 36 from both sides.

[tex]-36x + 36 - 36 = 180 - 36[/tex] [tex]-36x = 144[/tex]

Step 4: Divide both sides by -36.

[tex]\frac{-36x}{-36} = \frac{144}{-36}[/tex] [tex]x = -4[/tex]

Therefore, x = -4 for the second one!

x= -1
x= -2

The circle graph shows the results of a survey. Of those surveyed, 10 said no. About how many people were surveyed?

Answers

Answer:

50 people

Step-by-step explanation:

so to solve this we can use cross multiplying:

first we know that 20% = 10 people and 80% = x people (we put x because we don't know how many people)

then we set it up:

[tex]\frac{10}{20}[/tex] = [tex]\frac{x}{80}[/tex]

= 20x = 800

= x = 40

now it asks how many people were surveyed in total so we add the 10 + 40 = 50

50 people were surveyed

Good beach days were common in southern Florida, but every once in a while there was a day that made a trip to the beach a must. Little did I know, this particular day at the beach would change my summer and my life forever.The beach was crowded with the usual groups of regulars and tourists. Off in the distance, though, I noticed a large gathering of people. Just then, Roger, a friend of my family and a police officer, came over.I pointed to the crowd. Whats up with them?Theyre looking at the sea turtle nests, said Roger. We posted signs last summer listing some rules for the area. Though the signs might not be enough. Just the other day we found a nest that had been disturbedprobably by onlookers. The director at the conservancy doesnt think any hatchlings will make it out of that nest.Thats awful, I said.Its actually been problem for a long time. They need all the help they can get to protect the turtles. You know, I think the Sea Turtle Conservancy has an internship programRoger didnt have to say another word. The next day, I asked my mom for permission. A week after that, I was hired as an intern; I would start working at the conservancy on the first day of summer vacation.In my first days at the conservancy, I learned a lot about sea turtles, like their amazing instincts and adaptationthat a green sea turtle could hold its breath for as long as five hours, and could slow its heart rate to 10 beats per minute to conserve oxygen.But I also learned that they were vulnerable. It was not only the tourists on the beaches that were threatening the survival of the sea turtles. The turtles were getting caught in the nets dropped by fishing boats. Another major threat was the bright lights of the waterfront. I learned that when baby sea turtles hatch, they are naturally attracted to the light of the horizon. Since the area near the beach had become built up over the years, the lights of hotels and restaurants sometimes caused the hatchlings to move in the wrong direction. Unable to find the ocean and the food they needed to stay alive, they would die on the beach.That summer, I worked with willing fisherman to track migration patterns. This helped us develop better conservation plans. I also worked to alert businesses on the waterfront of the dangers that their bright lights posed to the hatchlings. I even worked with other interns to erect a wooden fence around the nesting site to keep visitors at a safe distance.I had no idea that one day and one moment would lead me to learn so much; I also never thought that I could make a difference. But, with a little knowledge and a lot of work, we were able to do just that and ensure that the sea turtle hatchlings would be safe for generations to come.Why does the narrator most likely choose to write about this experience?A)to describe how a persons mistakes can provide lessons for the futureB) to warn readers about how fishing impacts the ocean environmentC) to explain how a chance encounter can change a persons lifeD) to persuade other young people to volunteer in their communities show your solution need an answer, please need an answer, please.
