is 11^2 x 5^4 a factor of 11^3 x 5^4
No, 11^2 x 5^4 is not a factor of 11^3 x 5^4.
To see this, you can divide 11^3 x 5^4 by 11^2 x 5^4 and see that there is a remainder.
11^3 x 5^4 = (11 x 11 x 11) x (5 x 5 x 5 x 5)
= 121 x 625
= 75125
11^2 x 5^4 = (11 x 11) x (5 x 5 x 5 x 5)
= 121 x 625
= 75125
75125 / 75125 = 1 with a remainder of 0.
Therefore, 11^2 x 5^4 is not a factor of 11^3 x 5^4.

The cylindrical storage shed shown below is completely filled with road salt to make a town's roads safer during snow storms. About 21,000 cubic feet of road salt is used during a typical snow storm.
a. What is the total volume of the storage shed?
b. How many snow storms can the town expect to handle before the storage shed needs to be refilled with additional road salt?
The volume of the storage shed is 125600 ft³.
The storage shed will be refilled after using 125600 ft³ of salt.
How to find the volume of the storage shed?The cylindrical storage shed shown below is completely filled with road salt to make a town's roads safer during snow storms.
The volume of the storage shed can be found as follows;
volume of a cylinder = πr²h
where
r = radiush = heightTherefore,
r = 40 / 2 =20 ft
h = 100 ft
volume of the storage shed = 3.14 × 20² × 100
volume of the storage shed = 3.14 × 400 × 100
volume of the storage shed = 125600 ft³
Therefore, the storage shed can handle 125600 ft³ of salt before it needs to be refilled.

-50 POINTS- Already asked 3 times someone help pls. Don’t guess either.
Answer:
To find the coordinates of the point on the x-axis that is reflected over the x-axis from the point P, you can use the formula (x, -y). In this case, the x-coordinate of point P is 4, so the x-coordinate of the reflected point will also be 4. The y-coordinate of point P is 7, so the y-coordinate of the reflected point will be -7. Therefore, the coordinates of the reflected point are (4, -7).

Similar triangles are those triangle for which the ratio of corresponding sides is same without affecting the shape.
Given that ΔABC and ΔPQR are similar.
Let x be the side length of PR.
Ratio of their side lengths are equal.
AB : PQ = BC : QR = AC : PR
5 : 45 = 8 : 72 = 6 : x
Take the ratios 8 : 72 = 6 : x

If a new video game costs the store $25 and they sell it for 37.50, what was the percent markup?
The percent markup of the supplied statement is equal to 50% after the problem is solved.
How much of a markup should I use?There isn't a predetermined "optimal" markup percentage, however most companies set their markup at 50%. A 50% markup, also referred to as "keystone," denotes a price that is 50% greater than the cost of the commodity or service.
Exactly how is markup determined?The gross profit of a unit is determined by subtracting its cost to produce or acquire for resale from its sales price to determine the markup percentage. The markup percentage is computed as (12 - 8) / 8 and equals 50% if an item is priced at $12 but costs the manufacturer $8 to produce.
According to the given information:Cost price of game=$25
Selling price of game=$37.50
Profit = selling price - cost price
Profit = 37.50 - 25
Profit / markup percentage = (profit /cost price ) * 100
= (12.50/25) * 100
= 50%

solve the equation a^2x^2 = abx + 2b^2 using completing the square method
The solution to the equation is
x = b/a ± √(b^2/a^2) / a.
What is the equation?Generally, To solve the equation using the completing the square method, we first move all the terms to one side of the equation by subtracting abx and 2b² from both sides, giving us:
a²x² = abx + 2b²
Which is
a²x² - abx - 2b² = 0
Next, we need to add and subtract a term so that the left side of the equation can be written as a perfect square.
We need to find the square of half of the coefficient of the x term, which is -ab/2a.
So we add and subtract (ab/2a)^2 = (b^2/a^2) on the left side of the equation:
a²x² - abx - 2b² + (b²/a²) - (b²/a²) = 0
This gives us the left side of the equation as
(ax - b/a)² = b²/a².
We can then take the square root of both sides:
ax - b/a = ±√(b²/a²)
Finally, we can add b/a to both sides to get the solution:
x = b/a ± √(b²/a²) / a

Solve 10ax + 9b = 8cx + d for x
Answer:
Step-by-step explanation:
Step 1: Subtract 8cx from both sides of the equation to get
10ax + 9b - 8cx = d
Step 2: Subtract 9b from both sides of the equation to get
10ax - 8cx = d - 9b
Step 3: Multiply both sides of the equation by (-1/10) to get
-8cx/10 = -(d - 9b)/10
Step 4: Add (d - 9b)/10 to both sides of the equation to get
-8cx/10 + (d - 9b)/10 = 0
Step 5: Simplify the left side of the equation to get
x = (9b - d)/80
Therefore, x = (9b - d)/80 is the solution to the equation 10ax + 9b = 8cx + d.

Step-by-step explanation:
You want to know the inequalities represented on the graph showing a solid line with negative slope and a y-intercept of 2, and a dashed line with positive slope and a y-intercept of -1, where the shading is below both lines.
Line typeIf the line is included in the solution set (≤ or ≥ is used), the boundary line is graphed as a solid line. If the line is not included in the solution set (< or > is used), the boundary line is graphed as a dashed line.
Here, the line with positive slope is dashed, and the line with negative slope is solid.
y = x -1 . . . . is a line with positive slope
y = -2x +2 . . . . a line with negative slope
ShadingThe shading is below the line for y-values less than those on the line:
y < x -1 . . . . shading below a dashed line with positive slope
y ≤ -2x +2 . . . . shading below a solid line with negative slope
These are the inequalities of interest.
