Answer:
10 + 3x </= 30
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.
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.

Find the CIRCUMFERENCE of a circle with a RADIUS of 13mm. Use 3.14 for the value of pi.
Answer:
Circumference = 81.64
Step-by-step explanation:
The formula for finding circumference is C = pi(d). Since you don't have the diameter, but you do have the radius (which is half of the diameter), you will multiply 13 by 2, or 13 x 2. 13 x 2 = 26. So, the diameter is 26.
Fill in what you know: C = 3.14(26)
Now, all you have to do is multiply 3.14 and 26, which equals 81.64.
Hope this helps! :)

Answer:
q5. £40.50
q6. didn't know that one sorry
q7. $114.24
Step-by-step explanation:
q5. 55% of £90
10% = 9
5% = 4.5
to get to 50% you do 10% x 5 = 50%
you then do 9 x 5 = 45
after that you add the 45 + 4.5 = 49 .50
after that you do £90 - 49.50 = £40.50
q7. 12% of 102
10% = 10.2
1% = 1.02
2% = 2.04
12% = 10.2 + 2.04 = 12.24
then you do 102 + 12.24 = 114.24
Match the questions with the correct answers about the given box plot below

5. A
5. F
Step-by-step explanation:
The median can be found at the line inside of the box, the heaviest weight would be found at the right end of the line, and the smallest weight would be found at the left, the interquartile range is the difference of one end of the box to the other, and the range is the difference of the largest number of the entire diagram, from the smallest number.
Hope this helps you!
Answer:
Florida: The weight range = 10
Tennessee: The interquartile range = 4
Tennesse: Median Weight = 76
Florida: Median Weight = 80
Florida: Weight of the heaviest child = 84
Tennesse: Weight of the smallest child = 71
Step-by-step explanation:
Florida: How to find the weight range
The range of a data set is the difference between the minimum and maximum. To find the range, calculate xn minus x1.
R = xn − x1
Therefore, the weight range in Florida is 10
Tennessee: How to find the interquartile range
To find the interquartile range (IQR), first, find the median (middle value) of the lower and upper half of the data set. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
71, 72, 73, 74, 75, 76, 77, 78, 79, 80
Q1 = 74
Q2 = 78
78 - 74 = 4
Therefore, the interquartile range in Tennesse is 4
Tennesse: Median Weight
The median x˜ is the data value separating the upper half of a data set from the lower half.
Arrange data values from lowest to the highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
x˜ = 75.5
Therefore, the median weight of Tennesse is 76
Florida: Median Weight
The median x˜ is the data value separating the upper half of a data set from the lower half.
Arrange data values from lowest to the highest value
The median is the data value in the middle of the set
If there are 2 data values in the middle the median is the mean of those 2 values.
x˜ = 79
Therefore, the median weight of Florida is 80
Florida: Weight of the heaviest child
Since the smallest number in Florida is 84,
Therefore, the weight of the heaviest child in Florida is 84
Tennesse: Weight of the smallest child
Since the smallest number in Tennesse is 71,
Therefore, the weight of the smallest child in Tennesse is 71
Which of the following questions is a statistical question?
What is the top-selling board game?
In what aisle are the board games located in the local store?
How many board games require a deck of cards to play?

"How many board games have you played in the past month?"
Step-by-step explanation:
A statistical question is defined as a question that can be answered by collecting data that vary. Basically, it is a question that can be surveyed. The question, "How many board games have you played in the past month?", is the only one that is statistical because multiple different answers can be given to this question.

At 78°F, a certain insect chirps at a rate of 106 times per minute, and at 81°F, they chirp 112 times per minute. Write an equation in slope-intercept form that represents the situation.
Answer:
y=2x-50
Step-by-step explanation:
[tex]m=\frac{y^2-y^1}{x^2-x^1} = \frac{112-106}{81-78} =\frac{6}{3} =2[/tex]
slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:
y=mx+b
112=2(81)+b
112=162+b
Then subtract 162 from both sides, and b=-50
Plug in all numbers into original equation
y=mx+b m=2 b= -50
So u get y=2x-50
Answer:
y = (1/2)x + 25 or y = 0.5x + 25

Can someone please help me find the measure of the exterior angle.
Answer:
k = 140°
Step-by-step explanation:
The sum of the interior angles of any triangle = 180°.
64° + 76° + x = 180°
x = 40°
40° + k = 180° because they are supplementary angles
k = 140°
Answer:
k = 140°
Step-by-step explanation:
The sum of the interior angles of any triangle = 180°.
64° + 76° + x = 180°
x = 40°
40° + k = 180°
k = 140°
