The inequality is 25x + 60y + 180 ≤ 2500. x and y are variables.
What is inequality?
In mathematics, inequalities specify the relationship between two non-equal values. Equal does not imply inequality. Typically, we use the "not equal symbol (≠)" to indicate that two values are not equal. But various inequalities are used to compare the values, whether it is less than or greater than.
Given that a 180-pound person has a load of boxes to deliver. There are types of boxes. The weight of the first type of box is 25 pound and the second type of box is 60 pounds.
Let x represent the number of 25-pound boxes, and let y represent the number of 60-pound boxes.
The weight of x number of boxes is 25x
The weight of y number of boxes is 60y
The person carrying the box means he is also in the elevator.
The total weight of the boxes and the person is 25x + 60y + 180.
The elevator can hold a maximum weight of 2,500 pounds.
The wight of the boxes and the person must be less than or equal to 2500 pounds.
The inequality is
25x + 60y + 180 ≤ 2500

Step-by-step explanation:
Erika has a baking company and needs to purchase 17 2/5 pounds of flour for her cakes. The Baking Goods Store sells two different-sized bags of flour. The table shows the amounts of flour in the bag, the number of bags at the store, and the cost per bag of flour.
The number of small ball bags she will need is 7 small bags, the correct option is A.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given that;
Need of flour for cakes= 17 2/5 pounds
Now,
There are 4 large bags, and each one has 4 pounds.
She buys all of the large bags, she already has;
4x4=16
16 pounds. So, she only needs
17 2/5 -16= 1 2/5
=5/5+2/5
=7/5
1 2/5 pounds more, this fraction is equals to 7/5 pounds.
The small bags only contains 1/5 pounds of flour so,
7/5/1/5
=7*5/1*5
=7
Therefore, by algebra the answer will be 7 bags

What is the intermediate step in the form (x+a)2 = b as a result of completing the square for the following x^2=16x+8
The intermediate step in the form (x+a)2 = b is (x - 8)^2 = 72
How to determine the intermediate stepFrom the question, we have the following parameters that can be used in our computation:
x^2 = 16x + 8
Rewrite as
x^2 - 16x = 8
Take the coefficient of x
k = 16
Divide by 2
= 8
Square the quotient
= 64
So, we add 64 to both sides of the equation
So, we have
x^2 - 16x + 64 = 8 + 64
Express as squares and evaluate
(x - 8)^2 = 72
Hence, the intermediate step is (x - 8)^2 = 72

Your friend says, "We will each roll a die. If the highest number out of the two dice is a 5 or a 6, gaberil wins. And if the highest number out of the two dice is a 1, 2, 3, or 4, then justen win. Whoever wins the most out of ten tries, wins the taco. "
what is the that justen wins
The probability that Justen wins is 4/9.
Determine the probabilityThe probability that Justen wins is determined by the likelihood that the highest number rolled on the two dice is a 1, 2, 3, or 4. To find this probability, we can first calculate the probability that the highest number rolled is a 5 or 6, which is what would cause Gaberil to win.
The probability of rolling a 5 or 6 on one die is 2/6, or 1/3. The probability of rolling a 5 or 6 on both dice is (1/3) * (1/3) = 1/9.
However, we also need to account for the possibility that one die rolls a 5 or 6 and the other does not.
This can happen in two ways: either the first die rolls a 5 or 6 and the second does not, or the first die does not roll a 5 or 6 and the second does.
The probability of each of these scenarios is (1/3) * (2/3) = 2/9.
So the total probability of Gaberil winning is 1/9 + 2/9 + 2/9 = 5/9.
Since there are only two possible outcomes (either Gaberil wins or Justen wins), the probability of Justen winning is 1 - the probability of Gaberil winning. So the probability of Justen winning is 1 - 5/9 = 4/9.
Therefore, the probability that Justen wins is 4/9.

Equation:
Solve:
Answer: 28, 30, 32
Step-by-step explanation: The first integer is 28, the second is 30, and the third is 32. The difference from the first integer and the last integer should be 4. x is the first integer, so the equation is:
x+x+2+x+4=90
The first integer plus the second integer(x+2) plus the third integer(x+4) equals 90. Now solve.
x+x+2+x+4=90

She knows her own height and the height of the school. She also knows the distance from the mirror to the school from previous Geometry activity. She would like to calculate the distance she is standing from the mirror.
The height of the school is 30 ft.
The distance from the school to the mirror is 50 ft.
The height of the student is 6.3 ft.
What is the distance d between the student and the mirror?
The distance d between the student and the mirror is given by the similar triangles are d = 10.5 feet
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Araceli uses 8. 7 pints of blue paint and white paint to paint her bedroom walls. 1/4
of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Express your answer in fraction and decimal form. Solve on paper. Then check your work on Zearn
The amount of white paint did she use to paint her bedroom walls is 6 21/40 or 6.525 pints.
To find the amount of white paint used, we first need to find the amount of blue paint used. Since 1/4 of the total amount of paint is blue, we can multiply the total amount of paint by its fraction, 1/4, to find the amount of blue paint:
Blue paint = 8.7 pints × 1/4 = 87/40 = 2.175 pints
Now, to find the amount of white paint used, we can subtract the amount of blue paint from the total amount of paint:
White paint = 8.7 pints - 2.175 pints = 261/40 = 6.525 pints
So, Araceli used 6.525 pints of white paint to paint her bedroom walls.
In fraction form, this can be written as 6525/1000 pints, or 6 21/40 pints.
In decimal form, it is simply 6.525 pints.

Two water balloons were launched into the air at different moments and collided. The water balloons were modeled by the quadratic functions: y = −7x2 + 26x + 3 and y = −6x2 + 23x + 5, where y represents the height in meters and x represents the time in seconds after the launch. What is the time, in seconds, that the balloons collided at the highest point? 2.0 seconds 2.25 seconds 2.5 seconds 2.75 seconds
The time it takes is 2 seconds
What is the time the balloons collided at the highest point?
To find the time that the balloons collided at the highest point, we need to find the vertex of the resulting quadratic function.
First, we can set the two functions equal to each other, since they represent the height of the two balloons at any given time:
-7x^2 + 26x + 3 = -6x^2 + 23x + 5
Simplifying and rearranging terms, we get:
-x^2 + 3x + 2 = 0
Now, we can use the quadratic formula to solve for x:
x = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = -1, b = 3, and c = 2.
Plugging in these values, we get:
x = (-3 ± sqrt(3^2 - 4(-1)(2))) / 2(-1)
x = (-3 ± sqrt(1)) / (-2)
Simplifying further, we get:
x = (-3 ± 1) / (-2)
So, x can be either 1 or 2. However, we're only interested in the positive value for x since time cannot be negative.
Therefore, the time that the balloons collided at the highest point is:
x = 2 second
