Trash Management charges its customers a fee of $25 plus $8 for each trash can they need emptied. Waste Away charges its customers $12 per trash can with no fee. Write an inequality that can be used to determine the number of trash cans for which it is less expensive for a customer to use Waste Away as their trash service.
Answers
Answer:
after 5 trash cans the waste away would be cheaper
Step-by-step explanation:
28+8x
12x
you would plug in numbers for x until one of them is cheaper in this case waste away is cheaper by $8 after 5 trash cans
There are fewer than six trash cans, so it is less expensive for a customer to choose Waste Away as their trash service.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Let x be the number of trash cans.
The cost for Trash Management is 25 + 8x, and the cost for Waste Away is 12x.
To determine the number of trash cans for which Waste Away is less expensive, we need to find the number of trash cans such that the cost for Waste Away is less than the cost for Trash Management, which can be expressed as 12x < 25 + 8x.
Solving for x, we get 12x - 8x < 25, which simplifies to 4x < 25.
Dividing both sides by 4, we get x < 25/4.
Therefore, it is less expensive for a customer to use Waste Away as their trash service if they have fewer than 25/4 = 6.25 trash cans.
Since the number of trash cans must be an integer, the inequality can be rewritten as x < 6.

A. n > 6
B. n>3
C. n>1.5
D. n < 26
Answers
then dive both sides 2n>8
and get n>4
Answer: n>1.5
( n2 here means 2×n not n² )
Step-by-step explanation:
5 + 2n > 8
Subtract 5 from both sides
5 -5 + 2n > 8 -5
2n > 3. Divide both sides by 2
2n/2 > 3/2
n = 1.5

whats the surface area of this prism plz help.Urgent
Answers
Answer:
The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration.

Dillon decided to construct a rectangular deck in his back yard. It is 16 feet long and 13 feet wide. He is trying to determine whether he should construct the deck using cedar or a pressure treated material.
The cedar costs $21.09 per square foot for materials.
The pressure treated material costs $18.90 per square foot for materials.
The cost for labor will be the same for either material.
How much money would Dillon save installing a deck with pressure treated material instead of cedar? Explain or show your reasoning. You may use diagrams, drawings, or equations as well as words.
PLZZZ
Answers
Answer:
He would save $455.5
You would multiply 13 by 16 to get the total area of the deck.
Then you would multiply 208 times 21.09
Then you would multiply 208 by 18.90
You would get two numbers: 4386. 72 and 3931.2
You subtract the two numbers and you get 455. 52
Step-by-step explanation:
Answer:
455.52
Step-by-step explanation:
16x13=208
Cedar:
208x21.09= 4,386.72
Pressure-treated:
208x18.90= 3,931.2
Difference
4,386.72-3,931.2= 455.52

need answer ;w; In the equation -8x+ 1/4(20x - 12) = qx - 13x - 3, what value of q makes the equation
have infinitely many solutions?
A
-10
B 0 C 3 D 10
Answers
Answer:
i think it is B
Step-by-step explanation:
If 10x = qx for all values of x, then q must be equal to 10. so, the answer is (D)
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To have infinitely many solutions, both sides of the equation should be equal regardless of the value of x.
This means that the left side of the equation should simplify to a constant, and the right side of the equation should also simplify to the same constant.
Starting with the left side of the equation:
-8x + 1/4(20x - 12) = qx - 13x - 3
-8x + 5x - 3 = qx - 13x - 3 (distributing 1/4 to (20x - 12))
-3x - 3 = qx - 13x - 3 (combining like terms)
-3x = qx - 13x (subtracting 3 from both sides)
Now, let's simplify the right side of the equation:
-3x = qx - 13x
-3x + 13x = qx (adding 13x to both sides)
10x = qx
Hence, If 10x = qx for all values of x, then q must be equal to 10. so, the answer is (D)
