Answer:
9.6a + (−2)
Step-by-step explanation:
To simplify the expression (6 + 12.5a) - (8 + 2.9a), you'll need to distribute the negative sign inside the parentheses and then combine like terms:
(6 + 12.5a) - (8 + 2.9a) = 6 + 12.5a - 8 - 2.9a
Now, combine the like terms:
(12.5a - 2.9a) + (6 - 8) = 9.6a - 2
So, the simplest form of the expression is 9.6a - 2.

A. 9
B. 53
C. 81
D. 94
Answer: B. 53
Step-by-step explanation:
A square of 7 is 7*7 = 49
A square of 2 is 2*2 = 4
so Now,
49+4 = 53.
Simplifying 7² + 2² we get,
(7 x 7) + (2 x 2)
Solving the above equation we get,
49 + 4
53

A composite figure has a radius of 10 cm.
A circle with radius of 10 centimeters. One-quarter of the circle is cut out of the figure.
What is the area of this composite figure? Use 3.14 for Pi.
23.55 centimeters squared
78.5 centimeters squared
235.5 centimeters squared
314 centimeters squared
Answer:
C, 235.5 cm^2
Step-by-step explanation:
Formula for area of circle:
A = πr^2
Where π represents pi(3.14 or 22/7) and r represents the radius.
Plug in given value (10):
A = πr^2
A = 3.14(10)^2
A = 3.14(100)
A = 314
Now they say a quarter of this circle is cut out, which means we have to first find out what a quarter of this area is:
314/4
= 78.5
A quarter of this circle is 78.5, so let's subtract this from the total area (314):
314 - 78.5
= 235.5 cm^2
The area is 235.5 centimeters squared.

What is the mean of this data set?
30, 42, 47, 31, 38, 46
Answer:
The mean is 39
Step-by-step explanation:
Add together all the numbers and then divide them by how many numbers there are.
If you have any questions please ask me! :)
The mean of this data set is 39
The mean, or average, of a data set is calculated by adding all the numbers in the set together and then dividing by the count of numbers in the set. This provides a central value that represents the set of data.
Let's calculate the mean of your data set: 30, 42, 47, 31, 38, 46.
First, we add the numbers together:
30 + 42 + 47 + 31 + 38 + 46 = 234
There are six numbers in the data set, so we divide the sum by six to find the mean:
234 ÷ 6 = 39
So, the mean of this data set is 39. This tells us that if we were to distribute the values equally among the six data points, each point would have a value of 39. This is often used as a way to describe the central tendency or 'typical' value of a set of data. Always remember that the mean can be influenced by extreme values, known as outliers, which might not truly reflect the central tendency of the data. In this data set, however, all values are reasonably close together, so the mean is a good representation of the data.

Find the surface area of the composite figure
Answer:
364 cm or 368 cm
Step-by-step explanation:
top of pink cuboid is 2 x 2 which is 4
sides of pink cuboid are 6 x 6 and there are 4 of the same faces so 6 x 6 x 4
green cuboid side is 5 x 4 and there are 2 faces that are similar so 5 x 4 x 2
the other side of the green cuboid is 10 x 4 and there are 2 faces that are similar so 10 x 4 x 2
the bottom and top would be 10 x 5 and there are 2 faces that are similar so 10 x 5 x 2 but a chunk of the top face is being blocked so we have to subtract the amount thats blocking it off so we do( 10 x 5 x 2 ) - ( 2 x 2 ), 2 x 2 is the face blocking it off.
the total then adds up to 364 cm but if that doesnt work then do 364 because it might be trying to count in bottom face of the pink shape

Matt is selling tickets for the football game next week. His daily ticket sales over the past six days have been 37, 29, 37, 50, 45, and 38 tickets. His goal is to sell an average number of 40 tickets per day. To achieve Matt’s goal, how many tickets must he sell on the final day of the week?
A: 38 tickets
B: 44 tickets
C: 236 tickets
D: 280 tickets
Answer:
b is the answer
Step-by-step explanation:
lets make ‘ x ‘ the number of tickets he should sell on the final day.
make into a fraction;
[tex]\frac{37+29+27+50+45+38}{7} = 40[/tex]
37 + 29 + 27 + 50 + 45 + 38 = 280
236 + ‘ x ‘ = 280
⇒ ‘ x ‘ = 280 - 236
‘ x ‘ = 44
b being the answer

Answer:
Answer to 3rd image = b: the area of the circle is approximately 3 times greater than the circumferance
Explanation:
Circumferance =
[tex]\pi d[/tex]
Using this we can figure out that the circumferance is 37.704 cm or if we round it then it will be 38 cm.
Area of a circle =
[tex]\pi r^{2} [/tex]
Using this we can find that the area would be 113.112 cm² or if we round it, it becomes 114 cm².
Now let's go through the statements:
A) We know that there's no way that area is 8 times larger than circumferance because it would be 304 cm
C) The circumferance can't be an eight of the area as its approximately 4 times smaller.
D) The circumferance can't be 4 times greater as its 4 times smaller and its less than the area
We are left with B) which is the answer because 4 times the curcumferance would be 152 cm which is close enought to the area
so B) is the answer
For 4th image the answer is A) 15.7 / pi = d
Explanation:
We know that to find circumferance we use the formula:
pi d = circumferance
so we know that the circumferance is 15.7 cm so we are going to do the opposite.
pi = 3.142
If we do 15.7 / 3.142 we get 5 rounded up and we can check for any mistakes by doing 5 pi and its correct because we get 15.71 cm which is the same as 15.7 cm
so the answer is A)
Answer:A
Step-by-step explanation:
4th image the answer is A) 15.7 / pi = d
the formula:pi d = circumferance
we know that the circumferance is 15.7 cm so you can do the opposite.
pi = 3.142
If we do 15.7 / 3.142 we get 5 rounded up and we can check for any mistakes by doing 5 pi and its correct because we get 15.71 cm which is the same as 15.7 cm
answer is A)

The dot plots below show the weights of the players of two teams:
Based on visual inspection of the dot plots, which team appears to have the larger mean weight? (5 points)
a
Not enough information is available to draw a conclusion.
b
Both groups are similar.
c
Team C
d
Team D
Answer:
Team C appears to have the larger mean weight.
Step-by-step explanation:
After seeing the dot plot of two teams i.e. Team C and Team D the conclusion that can be drawn regarding the larger mean of the team is that:
Team C is expected to have larger mean since the dots are for the higher values of weights and hence will result in higher mean. whereas for team D the dots or frequencies are for smaller weights and hence will result in a less mean as compared to team C.
Hence, Team C appears to have the larger mean weight.

Translate the sentence into an equation. Nine times the sum of a number and 6 equals 8. Use the variable w for the unknown number.
Answer: 9 ( w + 6 )= 8
Step-by-step explanation:
"the sum of" usually indicates parentheses, I hope I helped!
Answer: 9(x+6)=8
Step-by-step explanation: The statement wants you to multiply 9 by the sum of a number and 6, which is equal to 8. The unknown number is going to be x, and we know that sum means the answer to an addition problem which means that x+6 will be multiplied by nine as the statement wants you to do. The statement also tells us that nine times the sum of a number and 6 is equal to 8. We have the first part of the problem solved all we need to do is set it equal to 8 which gives us the answer 9(x+6) = 8

The volume of a large Tank is 126 yd(3). It is 2 2/5 wide and 2 4/5 high. What is the length of the Tank?
Hi! I'd be happy to help you find the length of the tank. To find the length, we'll use the formula for the volume of a rectangular prism: Volume = Length × Width × Height.
The volume of the tank is 126 cubic yards, the width is 2 2/5 yards, and the height is 2 4/5 yards. First, let's convert the mixed numbers to improper fractions:
Width: 2 2/5 = (2 × 5 + 2) / 5 = 12/5 yards
Height: 2 4/5 = (2 × 5 + 4) / 5 = 14/5 yards
Now, we'll plug these values into the volume formula and solve for the length:
126 = Length × (12/5) × (14/5)
To isolate the length, divide both sides of the equation by (12/5) × (14/5):
Length = 126 / [(12/5) × (14/5)]
Length = 126 × (5/12) × (5/14)
Length = (126 × 5 × 5) / (12 × 14)
Length = 630 / (168)
Length = 3.75 yards
The length of the tank is 3.75 yards.
