Answer:
6x + 25 ≤ 135
Step-by-step explanation:
Maximum amount to spend = $135
Boxes of popcorn = 2
Boxes of candy = 3
Cost per box of popcorn = $6
For 3 boxes = $6 * 3 = $18
Cost per box of candy = $3.50
For 2 boxes = $2 * 3.50 = $7
Item cost = Cost of candy and popcorn = $18 + $7 = $25
Ticket price = $6
Inequality to find number of friends ;
Let number of friends = x
Ticket cost = 6x
Hence ;
Ticket cost + item cost ≤ 135
6x + 25 ≤ 135

Let's simplify step-by-step.
5x^3 + 3 + 2x^3 − x^2 + 1
= 5x^3 + 3 + 2x^3 + −x^2 + 1
Combine Like Terms:
= 5x^3 + 3 + 2x^3 + −x^2 + 1
= ( 5x^3 + 2x^3 ) + ( −x^2 ) + ( 3 + 1 )
= 7x^3 + −x^2 + 4
Answer:
= 7x^3 − x^2 + 4

7 students have 8 books each. Which helps you find the total number of books?
Answer:
21 Books in total
Step-by-step explanation:
If you just want the total number of books, here:
If each student has 3 books, and there are 7 students, we can create the equation: 7 * 3 :because this is showing that 7 people each have 3 books
7 * 3 = 21 so There are 21 books in total
Another we could write it is 3 + 3 + 3 + 3 + 3 + 3 + 3 because there are 7 students with 3 books each. Adding this up would equal 21.

Given:
The figure of a circle.
To find:
The measure of arc AD and measure of each arc.
Solution:
The measure of arc is equal to the central angle of that arc.
The central angle of arc AD is 105 degrees. So,
[tex]m(arc(AD))=105^\circ[/tex]
The central angle of arc BC is 35 degrees. So,
[tex]m(arc(BC))=35^\circ[/tex]
The central angle of arc CD is 50 degrees. So,
[tex]m(arc(CD))=50^\circ[/tex]
The central angle of a complete circle is 360 degrees. So,
[tex]m(arc(AD))+m(arc(BC))+m(arc(CD))+m(arc(AB))=360^\circ[/tex]
[tex]105^\circ+35^\circ+50^\circ+m(arc(AB))=360^\circ[/tex]
[tex]190^\circ+m(arc(AB))=360^\circ[/tex]
[tex]m(arc(AB))=360^\circ-190^\circ[/tex]
[tex]m(arc(AB))=170^\circ[/tex]
Therefore, the measure of arc AD is 105°, the measure of arc BC is 35°, the measure of arc CD is 50° and the measure of arc AB is 170°

Step-by-step explanation:
If 66% of a number is 72, find 11% of that number
Answer:
12
Step-by-step explanation:
For 66% of a number is 72, The value of 11% of number is,
⇒ 12.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
We have to given that;
There are 66% of a number is 72.
Now, We can assume that;
Let a number = x
Then, We can formulate;
⇒ 66% of x = 72
⇒ 66/100 × x = 72
⇒ 66x = 72 x 100
⇒ 66x = 7200
⇒ x = 7200 / 66
⇒ x = 109.1
Thus, We can formulate;
⇒ 11% of 109.1
⇒ 11/100 × 109.1
⇒ 12
Therefore, For 66% of a number is 72, The value of 11% of number is,
⇒ 12.

The sum of three consecutive numbers is 72. What is the smallest of these numbers? Set up an equation to solve.
Answer:
Let the three consecutive numbers be x,x+1,x+2 . The numbers are: 23,24,and25 and the smallest one is 23
Step-by-step explanation:
Answer: (x-1) + (x) + (x+1) = 72; smallest number is 23.
Step-by-step explanation:
The numbers are consecutive, meaning they sit next to each other on a number line. For example 4, 5, 6.
Because they are three consecutive numbers, their average will be the value of the middle one. For example the average of 4, 5, 6 is 5.
Knowing this, we can divide 72 by three to get the value of the middle number.
72/3 = 24, so the middle number is 24.
The numbers that fall either side of 24 on the number line are 23 and 25, so the three consecutive numbers are 23, 24, 25.
You can also set up and solve the equation: (x-1) + (x) + (x+1) = 72 because the numbers are consecutive.
To solve, combine like terms. The (-1) and (+1) cancel out and the equation becomes 3x = 72.
72/3 = 24, so x = 24, and the smallest term, (x-1) = 23.

Step-by-step explanation:
ez maths:
300 (total) divided by 20 (parts available) = how many people can sit at said part (15)
Answer:
Each section can hold 15 people.
Step-by-step explanation:
[tex]\frac{1}{y}=\frac{20}{300}[/tex]
y × 20 = 300 × 1

Alex bought some crayon pens and sketch pens in the ratio of 7:4.
Each crayon pen cost $2.
Each sketch pen cost $2 more than each crayon pen.
He spent a total of $360 on these crayon pens and sketch pens.
How much did he spend on the crayon pens he bought?
Answer:
$168.
Step-by-step explanation:
1 group of 7 crayon pens and 4 sketch pens = 7 x 2 + 4 x (2 + 2) = 14 + 4 x 4 = $30
Number of groups = 360/30 = 12
12 x 7 x 2 = 168
He spent $168 on the crayons.

If Janie cuts half a stick of butter into four equal pieces, one-eighth (1/8) portion of the whole stick of butter is in each of the pieces.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.
It is given that Jenny needs 1/2 of a stick of butter for a recipe. She cuts the half stick of butter into four equal pieces.
The portion of the whole stick of butter in each of the pieces is found as,
= (1/2) / 4
=1/8
Thus, if Janie cuts half a stick of butter into four equal pieces, one-eighth (1/8) portion of the whole stick of butter is in each of the pieces.

A dilation by scale factor then a translation of
4 units up.
Answer:
A reflection in the line y = -2, then a translation 2 units right.
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Rigid transformation are transformation that preserves the shape and size of the object. Rotation, reflection, translation are rigid transformation whereas dilation is not a rigid transformation.
Any transformation regarding dilation changes the side length of the object and hence the area.
From the question, only one option is right. The rest options are not right because they involve dilation. The correct option is:
A reflection in the line y = -2, then a translation 2 units right.

A. the control group in an experiment
B. the experimental group in a survey study
C. the experimental group in an experiment
D. the control group in an observational study
Answer:
A. the control group in an experiment
Step-by-step explanation:
Researchers give one group a new cold medicine and compare them with to a group that takes no medicine. The group that is not given any medicine is the control group in an experiment.
Who are researchers?Researchers are those who do research on something i.e. systematics and deep investigation into something.
What is control group?Control Group is that group in research which does not take any medication or untreated group.
During the research while a new type of medicine is to be tested, the group that receives the medication or being tested is called the experimented group and the group that does not receive the treatment is called the control group.
Hence, we can say that the group that is not given any medicine is the control group in an experiment.
