A fish tank has 240240240 quarts of water. Levi adds another 120120120 quarts to the tank. How many gallons of water are in the fish tank? gallons
The 90 gallons of water is in the fish tank if the fish tank has 240 quarts of water. Levi adds another 120 quarts to the tank.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.
We have a fish tank has 240 quarts of water.
Levi adds another, 1201 quarts to the tank.
Total water in the tank = 240 + 120 = 360 quartz
To convert quartz to gallon, divide by 4
Total water in the tank = 360/4 = 90 gallons
Thus, the 90 gallons of water is in the fish tank if the fish tank has 240 quarts of water. Levi adds another 120 quarts to the tank.

y=x^2 is reflected across the x-axis and then scaled vertically by a factor of 1/8
The parabola y=x^2 is reflected across the x axis and then scaled vertically by a factor of 1/8 is y = [tex]-\frac{1}{8}[/tex] x².
What is Equation of parabola?
The general equation of a parabola is: y = a(x-h²2 + k or x = a(y-k)² +h, where (h,k) denotes the vertex.
The standard equation of a regular parabola is y² = 4ax.
The given equation is of parabola : y= x²
Now, we have to reflect across the x- axis and then scaled vertically by a factor 1/8.

Answer:
3 1/2 square units
Step-by-step explanation:
For this small triangle whose vertices are on grid points, the use of Pick's theorem will give the area with the least work.
__
theoremPick's theorem says that the area is ...
A = i +b/2 -1
where i is the number of grid points inside the boundary, and b is the number of grid points on the boundary.
applicationHere, only the given coordinates are boundary points that are on grid points. (b = 3)
The figure shows us three grid intersections inside the boundary of the triangle. (i = 3)
That means the area is ...
A = 3 +3/2 -1 = 3 1/2 . . . . square units
_____
Alternate solution
The triangle is bounded by a square 3 units on a side. From that, we can subtract a 2×3 triangle at upper left, a 1×2 triangle at upper right, and a 3×1 triangle at the bottom. That leave a figure area of ...
A = 3² -1/2(2×3) -1/2(1×2) -1/2(3×1) = 9 -3 -1 -3/2 = 3 1/2 . . . . square units
(The area of a triangle is 1/2bh, where b and h are the base and height of the triangle.)
__
Another alternate solution can be had by using a formula with the vertex coordinates:
A = 1/2|(x1)(y2 -y3) +(x2)(y3 -y1) +(x3)(y1 -y2)|
= 1/2|(-8)(3 -5) +(-5)(5 -2) +(-6)(2 -3)| = 1/2|16 -15 +6| = 3 1/2 . . . square units

Theo, Nancy, and Mary each drove separately to meet at their grandmother’s house for dinner. Theo drove 50 miles, Nancy drove √2,840 miles, and Mary’s route is shown below.
A right triangle with side lengths 48 miles and 13 miles. The hypotenuse is labeled Mary's Route.
Approximately how many miles did Mary drive to her grandmother’s house?
Order the distances that each family member drove to their grandmother’s house from least to greatest.
Answer:
Mary's route = 49.73 miles
Step-by-step explanation:
[tex] {r}^{2} = {x}^{2} + {y}^{2} [/tex]
[tex]r = \sqrt{ {x}^{2} + {y}^{2} } [/tex]
[tex]r = \sqrt{ {48}^{2} + {13}^{2} } [/tex]
[tex]r = \sqrt{2473} [/tex]
[tex]r = 49.73 \: miles[/tex]
[tex] \sqrt{2840} = 53.3 \: miles[/tex]
Arranging the distances from least to greatest:#1: Mary's route = 49.73 miles

Answer:
C) <AFL
Step-by-step explanation:
The middle angle typically goes in the middle of the three letters. So, the naming should look like <FAL or <LAF. The letter A would have to remain in the middle for the naming to be correct.
Angles can be named in these following ways:
- By three capital letters (vertex (middle point) always in the middle)
In this case it would be <FAL or <LAF.- By one capital letter (typically the vertex)
In this case it would be <A- By a lowercase letter or number that is in the middle of the angle
In this case it would be <5.Therefore, the incorrect naming would be C) <AFL, since the vertex isn't in the middle.

Step-by-step explanation:
The base of a prism has n sides. Find the numbers of faces, edges, and
vertices of the prism. Explain your reasoning.
Answers:
faces = n+2edges = 3nvertices = 2n===========================================================
Explanation:
Think of a hexagonal room with n = 6 walls, i.e. the floor is a hexagon with n = 6 sides. The floor and ceiling are parallel to each other, and congruent hexagons. That's 2 faces so far. Then we have another 6 faces to account for the walls. This gives 2+6 = 8 faces of a hexagonal prism.
In more general terms, a prism with a base of n sides will have 2 parallel and congruent base faces, and n walls or lateral faces. This gives n+2 total faces.
------------------------
Let's go back to the hexagonal prism. The floor has 6 sides to it, and so does the ceiling. We have 6+6 = 12 edges so far. Then we have another 6 edges where each of the rectangular walls meet up. That gives 12+6 = 18 edges total of this hexagonal prism room.
For any more general case, each base has n sides. That gives 2n sides so far for just the bases. Then add on another n for the lateral edges and we get 3n total edges.
--------------------------
Once again lets revisit the room with the hexagonal floor and ceiling. The floor has 6 vertices and the ceiling has the same vertex count. Therefore, this prism has 6+6 = 12 vertices.
For the general case, each base has n vertices. There are 2 such identical bases giving 2n vertices total.
---------------------------
One way to check the answer:
We could use Euler's Polyhedron Formula which is
F+V-E = 2
where,
F = number of facesV = number of verticesE = number of edgesFor the hexagonal prism we found
F = 8V = 12E = 18Then notice how
F+V-E = 2
8+12-18 = 2
20-18 = 2
2 = 2
This confirms the formula works for a hexagonal prism.
Now let's check it for the more general case
We found earlier that,
F = n+2V = 2nE = 3nSo,
F+V-E = 2
n+2+2n-3n = 2
3n-3n+2 = 2
0n+2 = 2
0+2 = 2
2 = 2
This helps confirm the answer for any prism with the base of n sides.

There are 50 roses in a tray. There is at least 1 red rose among any 24 randomly selected roses, and there is at least 1 white rose among any 28 randomly selected roses. How many white roses are there in the tray?
Help Pleaseee!!!!
By using the second condition, we conclude that there are 23 white roses in the tray.
How many white roses are in the tray?
First, we know that there are a total of 50 roses in the tray, and we have the conditions:
"There is at least 1 red rose among any 24 randomly selected roses""There is at least 1 white rose among any 28 randomly selected roses".The second statement means that, always that we take 28 roses, at least one of them is white. So, there are 27 roses in the tray that are not white.
Whit that in mind, if the 28th rose must be white, then all the remaining roses in the tray are white, this means that there are:
50 - 27 = 23 white roses.
