How are algebra tiles named?
We name the Algebra Tile pieces by considering the area of each, meaning we need to know the dimensions of each piece. If the small yellow square has a length of 1 unit, the area of the small square is 1 square unit. Then the long green rectangle has dimensions 1 by x and has an area of x square units.
What are algebra tiles examples?
Algebra tiles are square and rectangle-shaped tiles or tiles that represent numbers and variables. For example, we can use square tiles to represent numbers. Each square tile is equal to one. So, four can be represented by four square tiles.

37.5(3.8-x)+90x=300 please help me
Answer:
I’m just copying his answer which is 3
Step-by-step explanation:
at least I tried
Answer: 3
Step-by-step explanation:
37.5 (3.8-x) + 90x = 300
First, you have to simplify, by using the Distributive Property.
142.5 - 37.5x + 90x = 300
Now, add the like terms
142.5+ 52.5x = 300
Now, isolate the variable, meaning the variable has to be on one side on its own. You would have to subtract 142.5 and move it to the other side
52.5x = 300 - 142.5
52.5x = 157.5
Then, you divide!
[tex]\frac{52.5x}{52.5x}[/tex] = [tex]\frac{157.5}{52.5x}[/tex]
= 3

The base of a rectangular prism has an area of 19.4 square meters and the prism has a volume of 306.52 cubic meters. Write an equation that can be used to find the height h of the prism. Then find the height of the prism.
Answer:
15.8
Step-by-step explanation:
The formula would be V = Bh, the Base being LxW.
Since we already know the base and volume, we can substitute it into the formula.
306.52 = 19.4(h). Divide by 19.4, and you get 15.8 as your answer.

Step-by-step explanation:
Answer:
30.5
Step-by-step explanation:
Measure of angle A and B equals 110 because of how triangles work
Therefore 3x + x + 4 = 110
4x + 4 = 110
Subtract 4 from each side
4x = 106
Divide both sides by 4
x = 26.5
Measure of angle ABC equals 26.5 + 4 = 30.5

Over a 4.5 hour period, the rain gauge collected 2.8 inches of rain. In the
next 19.5 hours it collected an additional 1.75 inches of rain. What is the
total amount of rain, in inches, that the gauge collected?
Your answer
Select all the expressions that are equivalent to 1.94
~
2.37 -0.43
Answer: 4.55 inches of rain
Step-by-step explanation: Is this a trick question? It's a lot easier than it looks...but i'll give you a step by step explanation.
So, we know is 4.5 hours it collect 2.8 inches of rain, must have been a rainy day.
The next day the gauge collect 1.75 inches of rain, it must have sprinkled a little.
2.8 + 1.75 = 4.55
Therefore, the guage collected 4.55 inches of rain in total.

What is the area of the base of a cylinder with a volume of 174π in.3 and a height of 12 inches?
Answer:
The area of the base is 14.5π in²
Step-by-step explanation:
The volume of a cylinder is given by
Volume =base\:area \times height
Or
V=Bh
It was given that the volume of the cylinder is 174π in³.
The height was given as 12 inches.
We substitute to get,
174π=12B
Divide both sides by 12 to get:
B=14.5π in²
Hence the area of the base is 14.5π in²
Hope this helpsBrainliest plzand have a wonderful dayAnswer:
area of base = 14.5π in²
Step-by-step explanation:
the area of the base of a cylinder with a volume of 174π in^3 and a height of 12 inches is found by applying the formula for the volume of a cylinder:
V = πr²h
Here the area of the base of a cylinder with a volume of 174π in³ and a height of 12 inches, and so:
V = πr²(12 in) = 174 π in³
Dividing both sides by 12 in isolates πr², which is the area of the base:
174π in³
area of base = πr² = --------------- = 14.5π in²
12 in

Find the area of the kite.
Answer:
[tex]176.25inches^{2}[/tex]
Step-by-step explanation:
The formula for the area of the triangle is : [tex]\frac{base*height}{2}[/tex]
To work this out you would first need to break the shape down into 4 smaller triangles.
Then you would need to work out the area of the triangles. You can do this by multiplying the base by the height and dividing it by 2. We will first work out the area of the first triangle at the top. To work out the area you would multiply the base of 7.5 by the height of 7.5, this gives you 56.25. Although the formula says you should divide the answer by 2 however as there are two identical triangles this action does not need to be done.
The next step is to work out thew area of the bottom triangles. To do this you would multiply the base of 7.5 by the height of 16, this gives you 120.
Now that we have found the area of both sides of the kite we can now add the values of 56.25 and 120 to work out the full area of the kite, this gives you 176.25 square inches.
1) Break the kite into smaller triangles.
2) Work out the area of the triangles at the top.
[tex]7.5*7.5=56.25[/tex]
3)Work out the area of the triangles at the bottom.
[tex]7.5*16=120[/tex]
4) Add the area of both sides.
[tex]56.25+120=176.25inches^{2}[/tex]
During the first week students of RSM solved 25 percent of their monthly quota of problems. In the second week, they solved 110 percent of the number of problems solved in the first week. In the third week they solved 60 percent of the problems they had solved during the first two weeks and, in the fourth week, they solved the remaining 320 problems. How many problems did the students solve during the month?
Answer:
2000 problems
Step-by-step explanation:
1st week - 0.25x
2nd week - 1.10(0.25x)
3rd week - 0.6(0.25x + 1.10(0.25x))
4th week - 320
Than to solve for the monthly quota, equate the sum of all the problems solved to x and determine its value. Thus, the students solved 2000 problems all in all.
