=(-4x - x)/6 +12

= -5x/6 + 12

Answer: The answer is 7 1/6

Step-by-step explanation:

you have to solve the problem inside the parentheses and subtract it to get your final answer

Answer: 6.25,-5

Step-by-step explanation:

all you have to do is go along the x and then the y-axis. the point is roughly 6.25 and because the y-axis is below 0 it will be minus therefore -5.

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

Solving the Multiplication and then the Addition part of the given equation the answer we get is B. 53

First, solve any operations inside brackets. Second, solve any exponents. Third, solve all multiplication and division from left to right. Fourth, solve all addition and subtraction from left to right. This is the Solving Pattern you should always follow.

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.

Answer: I believe it is 508 cm²

Step-by-step explanation:

Start out by finding the surface area (SA) of the 2 shapes. The formula for SA is 2(wl + wh + wh).

Blue shape: 2(12x2 + 12x10 + 2x10) = 328 cm²

Red shape: 2(8x3 + 8x6 + 3x6) = 180 cm²

Now that the surface area of both shapes are solved, just add them together and you will get the answer of 508 cm²

Answer: x = 18 + 12

Step-by-step explanation:

Using the variable (x), you are able to give a number to any equation. By adding the 2 together, you end up with what (x) is going to be. Now solve for (x).

x = 18 + 12

x = 30

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)

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.

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.

1st line graph mean: 132.25 LARGER

2nd line graph mean: 123.125

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.

Answer: 356 total square inches

Step-by-step explanation: (12*13)+(10*10)=156+100=356 square inches

Answer: It is below with explanations on how to do it! :D

Step-by-step explanation:

1. First one shows a graph and a line. Remember, the equation for this is y = mx + b. The point that crosses the y-axis is 0. So far, the equation looks like this: y = mx + 0. In order to find the slope, we have to choose another point on the graph. I will choose the point (-4, -2). The slope is the direction of the line travelling from left to right. So to get from (-4, -2) to the point 0, aka origin, we have to go up 2 units and move 4 units to the right. This method is called rise over run. Now the slope is 2 over 4 -> 2/4.

Final answer is y = 2/4x + 0

Simplified version is y = 1/2x + 0

That is your equation in slope intercept form!

2. The second one shows a graph and is asking to write an equation in slope-intercept form. Here is the equation for that -> y = mx+b

M is the slope, and b is the y-intercept (where the point crosses the line on the y-axis).

So, in this case, M=4 and b=0

Plug it into the equation, y = 4x + 0

The graph is attached below (I did not draw it but I took a screenshot from a video that shows it)

I also attached the graph for you for the last question!

I hope this helps you :)

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.
