He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.
Step-by-step explanation:
10 + 3x </= 30
10 is the minutes for the centerpiece
3 is the minutes to make each small crane
x is the number of small cranes he can make
he has less than or equal to 30 minutes to complete them.
10 + 3x </= 30
subtract 10 from both sides
3x </= 20
x </= 6.666
He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.

Answer:
f the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.
Step-by-step explanation:
Answer:
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.
Step-by-step explanation:
Which relationship is a function ?
Answer:
A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

A cube has a side length of 1 inch. What is the volume of the cube?
Answer:
1 inch³
Step-by-step explanation:
Why, why does it have to be an inch, alright. So, you have to find the area of one side and multiply it by the length, the catch is that it's all 1, so 1 x 1 x 1 = 1, so your answer is the cube's length is 1 inch³

Can yall tell me what B is? b-7/4=-2/3
Answer:
1 1/12
Step-by-step explanation:
b-7/4=-2/3
First, in an equation like this, you add 7/4 to each side which will look like this:
b-7/4=-2/3
+7/4=+7/4
We add 7/4 to each side of the equation to balance the numbers.
b=+7/4-2/3 (because the minus symbol is in front, we put that)
Before adding we have to find the least common denominator known as LCD.
We find that by first looking at the denominators or the fractions which are 4,3
4,8,\12/,16,20,24.
3,6,9,\12/,15,18,21,24.
We can also find the LCD by multiplying 3 and 4. As you can see in the list, there are 12's in each list of numbers. We use that to change our fractions.
From the number 4 we find out how many times (x) we have to add 4 to get 12. We do 12/4 which is 3. And 12/3 which is 4.
7 x 3 2 x 4
------- - -------
4 x 3 3 x 4
which equals 21/12-8/12. Now that we have a common denominator, we can subtract.
21 8 13
--- - --- = ----- = 1 [tex]\frac{1}{12}[/tex]
12 12 12

Of the two lights on Dexter Street, the probability of the lights being red is 20% for the first light and 30% for the second light. If a car is driving down Dexter Street, what is the probability that it does not get stopped at either light?
The probability that it does not get stopped at either light is 14/25.
We have given
Of the two lights on Dexter Street, the probability of the lights being red is 20% for the first light and 30% for the second light.
What is the formula for probability?
The probability of an event A is defined as the ratio of the number of favorable events that occurred in A /total number of events in a sample space
Red light for the first:
The Probability of the red light is 20 out of 100 so you would just find the difference which is 80%.
80/100
Red light for the second:
The Probability of the second red light is 30 out of 100 so you would just find the difference which is 70%.
70/100
The probability of not being stopped at either, multiply across and reduce.
[tex]80/100 * 70/100= 14/25[/tex]
Therefore, The probability that it does not get stopped at either light is 14/25.

Using the two-way table, what percentage of the students that like to travel out of state do not like camping? Round to the nearest whole percent.
Likes Traveling Out of State Does Not Like Traveling Out of State Row totals
Likes Camping 52 38 90
Does Not Like Camping 36 74 110
Column totals 88 112 200
30%
33%
36%
41%
to find a percentage of something you take the fraction and multiply it by a hundred
Step-by-step explanation:
step one
to determine what the fraction would be you just read the question:
first you have to see what they want to calculate the percentage of. In this case it's students who like traveling out of state but don't like camping.
88 students like traveling out of state and 36 of those students don't like camping so the fraction you have to use is 36/88
step two
next you multiply your fraction by 100 to calculate your percentage
36/88 ×100= 40.9%
step three
since you have to round to the nearest whole percent your answer would be 41%
Answer:
The Answer is 41%

The dot plot shows the ages of the members in a club.
Select from the drop-down menus to correctly complete the statement.
If the youngest member leaves the club, the mean age of the club members would [increase/decrease/stay the same], but the median age would [increase/decrease/stay the same].
Answer:
Mean would increase
Median would stay the same
Step-by-step explanation:
The mean would increase because the lowest number would not make the mean lower
The median would stay the same because there are three numbers with the value of 48, which is the median, and if 45 is gone, it would stay the same
If the youngest member leaves the club, the mean age of the club members would increase but the median age would stay the same.
What are mean and the median?Mean is the ratio of the sum of all values in a data set to the total number of items in the data set.
The median is the middlemost value in a given data set.
Given that, a dot plot shows the ages of the members in a club,
The mean would increase because the lowest number would not make the mean lower,
The median would stay the same because there are three numbers with the value of 48, which is the median, and if 45 is gone, it would stay the same.
Hence, If the youngest member leaves the club, the mean age of the club members would increase but the median age would stay the same.
