Answer:
20
Step-by-step explanation:
0.5-0.4=0.1,0.1/0.5×100= 20
The students's estimation is 80%.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given that a student has a container with a volume of 0.5 liter.
He estimates the volume to be 0.4 liter.
Now to find the percentage of estimation,
estimated volume = correct volume × required percentage / 100
0.4 = 0.5 × required percentage / 100
Required percentage = 0.4 × 100 / 0.5
Required percentage = 0.4 × 100 / 0.5
Required percentage = 80%
Therefore, the students's estimation is 80%.

A public rectangular-shaped pool is 15 m by 30 m. Public pools must be surrounded by a cement
walkway of uniform width whose area is at least as large as the area of the pool. What is the
minimum width of the walkway? Show the steps of your solution.
Answer:
15m I think
Step-by-step explanation:
Sorry if im wrong
The area of a rectangle can be found by taking the product of length and breadth. The minimum width of the walkway is 15 m.
What is a Rectangle?A quadrilateral that has its opposite sides as equal and all the angles are right angle is called a Rectangle. The diagonal of a rectangle is greater than its length and breadth.
The given rectangle has dimension of 15 × 30.
Suppose the uniform width of walkway be d.
Then, the area of walkaway can be written as
Area = (15+d)×(30+d) - 15×30
As per the question,
15×30 = (15+d)×(30+d) - 15×30
(15+d)×(30+d) = 2×15×30
d^2 + 45d - 900 = 0
d = -60,15
As, length cannot be negative. Thus, d = 15m.
Hence, the minimum width of walkway is 15m.

can somebody please help me find this answer I will mark brainliest
Answer:
65 degrees
Step-by-step explanation:
The missing angle on the bottom is 35 degrees. This is because it lies on a straight line with the other angle being 145 degrees and a straight line is always 180 degrees, so 180-145=35 degrees. Now we have to find x so we should add the two known angles (35+80=115) and subtract it from 180 (180-115) to get 65 degrees for x.

Answer:
Huh!
The circles with of same radii or same circumference or same area are congruent.
No need to proof!
Step-by-step explanation:
Or just type it,
'Since they have the same radii, they are congruent!'
The two given circles are congruent as their radius are similar.
What is a circle?All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.So, the two circles are congruent because:
We know that:
AB = CDAnd AB and CD are the two radius of the given two circles.Since their radius is similar.So, the two circles will be congruent.
Therefore, the two given circles are congruent as their radius are similar.

What expression is equivalent to that, pleas give me a simple easy answer
Answer:
Every day for four years, I would drive to my job, and every day at the same time, on the same route, I would notice the city bus. It would pull up next to me, and I would see all the people on board. Some would be reading. Some would be sleeping. Some would stare back at me. Every day, at the same time, it would follow me right to work. As I pulled into my parking space at work, I would see it around the corner, about a block away from my job. Then, one day, my car broke down. I had no way to get to work, and then, I remembered the bus. I decided to take it since I knew it was on the same schedule as I was. Since then, I have never driven to work again. Taking the bus is a useful method with which to travel because you can save a lot of money by using public transportation. One reason public transportation is useful is because it saves money. My commute to work was long, and it required a lot of gas. When I drove to work, I was spending $30 a week on gas. There are 52 weeks in a year. That translates to $1,560.00 a year I was spending on gas to get to work. When I started taking the bus, it cost $2 ($1 to get to work and another $1 to get home). Another way to save money is to use the toll road. That translates to $10 a week. That means that it cost me $520 a year to get to work. That's less than a third of what it cost to drive. It saved me $1,040.00. The funny part is that the reason my car broke down in the first place was because I was driving it constantly. 6 What is the central idea of this passage?
