Answer:

B. 8n²−16n=−68

Step-by-step explanation:

First - Distribute the n & 10

n * 8n & n * -6 = 8n² - 6n

10 * -n & 10 * 7  = -10n +70

Second -  Move the 2 by subtracting

8n² - 6n - 10n +70 = 2 -> 8n² - 6n - 10n +70 - 2 = 2 - 2

Third - Combine like terms

-6n - 10n = -16n

70 - 2 = 68

8n² - 16n + 68 = 0

Fourth - Move 68 by subtracting

8n² - 16n + 68 - 68 = 0 - 68

8n² - 16n = -68

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Answer:

Step-by-step explanation:

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Answer: 23 dimes & 7 quarters

Step-by-step explanation:

You can create two equations:

\(\left \{ {{x + y = 30} \atop {0.10x + 0.25y =4.05}} \right.\)

Rearrange x + y = 30:

\(y=30-x\)

Substitute it into the x-value of the other equation & solve:

\(0.10x + 0.25y =0.10x + 0.25(30-x)=4.05\\0.10x+7.5-0.25x=4.05\\0.10x-0.25x=4.05-7.5\\-0.15x=-3.45\\x=\frac{-3.45}{-0.15} =23\)

With the x-value, substitute it back to the original equation to find y-value:

\(y=30-x=30-23=7\)

Therefore, there are 23 dimes & 7 quarters.

There are 23 dimes and 7 quarters.

Given that, the total number of coins=30.

To convert dimes to dollars we need to multiply the number of dimes by 0.1.

Let the number of dimes be x, and then the number of quarters will be 30-x.

Now, x×0.1+(30-x)×0.25=4.05

⇒-0.15x=-3.45

⇒x=23

30-x=7

Hence, there are 23 dimes and 7 quarters.

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

(3, 1)

Step-by-step explanation:

We are given the following system:
4x + y = 13

x - 3y = 0

We want to find the solution.

We can solve this system with substitution, where we solve one of the variables for the other, then substitute that value into the other equation.

To start, we can add 3y to both sides to solve for x.

x - 3y = 0

 +3y    +3y

____________________

x = 3y

Now, substitute x as 3y in 4x + y = 13

4(3y) + y = 13

12y + y = 13

13y = 13

y = 1

Now, substitute 1 as y in x=3y

x = 3(1)

x = 3

Our solution is x = 3, y = 1. As a point, that is (3,1).

The surface area of the top open cylinder is 6810.149 sq.cm.

A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.

Surface area of a cylinder = Base area + Lateral area

Base area of a cylinder = 2 × π × r²

Lateral area of a cylinder = (2 × π × r) × h

Therefore, here base area of a cylinder = 2× π × 12²

                                                                  = 5837.27 sq.cm.

And, lateral area of a cylinder = (2 × π × 12) × 2

                                                  = 972.8784 sq.cm.

Therefore, total surface area of a cylinder = 5837.27 + 972.8784

                                                                      = 6810.149 sq.cm.

Answer:

Step-by-step explanation:

To solve this problem, we can start by finding the possible range of values for the volume of the cuboid, which is at least 150 cm^3. The volume of a cuboid is given by the formula V = lwh, where l is the length, w is the width, and h is the height. Since the volume is at least 150 cm^3, we can set up the following inequality:

V >= 150

lwh >= 150

Next, we can find the possible range of values for the surface area of the cuboid, which is less than 320 cm^2. The surface area of a cuboid is given by the formula A = 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height. Since the surface area is less than 320 cm^2, we can set up the following inequality:

A < 320

2lw + 2lh + 2wh < 320

Now, we can solve these simultaneous inequalities to find the possible values of x, which represent the lengths, widths, and heights of the cuboid. To do this, we can start by finding the possible values of l, w, and h that satisfy both inequalities.

One way to do this is to rewrite the inequalities in terms of a single variable, such as l, and then solve for the possible values of l that satisfy both inequalities. For example, we could substitute the expression for the volume (lwh) and the expression for the surface area (2lw + 2lh + 2wh) into the inequality for the volume (V >= 150) and the inequality for the surface area (A < 320), respectively, and then solve for the possible values of l that satisfy both inequalities.
