Answer:

(D) 7, 3

Step-by-step explanation:

If a set has 'n' elements, the total number of subsets is (2^n) - 1

So if set A has more subsets than set B, it needs to have more elements, so option (A) and (B) can't be correct.

So, checking option (C), we have:

Set A: number of subsets = 2^8 - 1 = 255

Set A: number of subsets = 2^4 - 1 = 15

Difference: 255 - 15 = 240

The difference is not 120, so this is not the correct option

Option (D):

Set A: number of subsets = 2^7 - 1 = 127

Set A: number of subsets = 2^3 - 1 = 7

Difference: 127 - 7 = 120

Correct option: (D)

Answer:

Answer rounded to the nearest hundredth:

Step-by-step explanation:

Let S be the area of the sector

and A be the area of the whole circle

360 corresponds to the area of the whole circle

80 corresponds to the area of the sector

means

360 —————————-> π×8²

80   —————————-> S

then

[tex]S=\frac{80*(\pi*8^2) }{360}= 44.680428851055[/tex]

Answer:

1042 square inches is the total surface area of composite solid.

Step-by-step explanation:

It is clear from the image that the resulting composite solid is a cuboid.

whose sides are as follows:

Across the length there are 3 blocks along the side of 7 inches each.

Length = [tex]7 \times 3 = 21\ inch[/tex]

Width = 5 inch

Across the height there are 4 blocks along the side of 4 inches each.

Height = [tex]4 \times 4 = 16\ inch[/tex]

We know that total surface area of a cuboid is as follows:

[tex]\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)[/tex]

[tex]\Rightarrow 2 (21 \times 5 + 16 \times 21 + 16 \times 5 )\\\Rightarrow 2 (105 + 336+80)\\\Rightarrow 2 \times 521\\\Rightarrow 1024[/tex]

Hence, total surface area = 1024 square inches

Answer:

1/3 cup = 12 Small

Small = 1/3 / 12

Small = 1 /(3 x 12)

Small = 1 /36 cup

1/3 cup = 8 Big

Big = 1/3 /8

Big = 1 / (3 x 8)

Big = 1/24 cup

Step-by-step explanation:

The milk used for each cupcake if each batch of cupcake mix requires 1/3 of a cup of milk and the batch can make 12 small cupcakes or 8 large cupcakes is 1 / 24 cup.

It is the basic arithmetic operation, in which you are separating the number into some parts.

Given:

The milk required for each batch of cupcakes = 1 / 3 cup of milk,

The total number of large cupcakes that can be made from each batch = 8,

If Emma wants to make a batch of large cupcakes, then it will require,

1 / 3 cup milk = 8 cupcakes,

1 cupcake = 1 / 3 ÷ 8

1 cupcake = 1 / 24 cup of milk,

Therefore, the milk used for each cupcake is 1 / 24 cup.

There are 8 white squares in the tile pattern.

Given that, there are 48 white tiles in the pattern.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of gray squares be x.

Here, a tile pattern has 6 times as many white squares as gray squares

Then, white squares = 6x

Now, 6x=48

⇒ x=8

Therefore, there are 8 white squares in the tile pattern.

Answer:

Step-by-step explanation:

a+b=191

a-b=63

i sum these

a+b+a-b=191+63

2a=254

a=254/2

a=127

b=191-127

b=64

Answer:

127 and 64

Step-by-step explanation:

To solve this, we can set up a system of equations.

We can name the first number x and the second number y.

x+y=191

x-y=63

We can use elimination to eliminate the y variable.

We do this by adding the equations together

  x+y=191

+ x-y=63

_________

2x=254

Divide both sides by 2.

x=127

Now we can plug that in to find y.

x+y=191

127+y=191

Subtract 127 from both sides.

y=64

So our two numbers are 127 and 64.

The answer to this question is the letter D.

The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.

How to find the correlation coefficient for the data table -0.93,-0.27, 0.27, 0.93?

This is because the correlation coefficient focuses on the linear relationship between two variables.

Correct question:

Jada walks up to a tank that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water. At what rate is the amount of water in the tank changing? use a signed number, and include the unit of measurement in your answer.

Answer: - 2/3

Step-by-step explanation:

Given the following :

Amount of gallon tank can hold = 10

tank drains at a constant rate :

First look tank contains 7 gallons

After 3 minute,

Tank contains 5 gallons

Thus signifies a 2 gallon decrease in volume of water after 3 minutes

Therefore, the rate of change =( change in volume) / time

Rate of change = (final volume - initial volume ) / 3

(5 - 7)/ 3 = - 2/3

Answer:

~460032.8

Step-by-step explanation:

Essentially, when this is written out, we get:

6 ÷ 2 × 3 × 100 × 700 ÷ 1.37 × 0.778 + 0.778913 × 100 × 10 × 1.77 × 444444.47 ÷ 7777777.0999 + 100

Order of operations says to do multiplication and division first, so let's calculate 6 ÷ 2 × 3 × 100 × 700 ÷ 1.37 × 0.778 separately:

6 ÷ 2 = 3

3 × 3 = 9

9 × 100 = 900

900 × 700 = 630000

630000 ÷ 1.37 = 459854

459854 × 0.778 = 357766

Now calculate 0.778913 × 100 × 10 × 1.77 × 444444.47 ÷ 7777777.0999:

0.778913 × 100 × 10 × 1.77 × 444444.47 = 612744929

612744929 ÷ 7777777.0999 ≈ 78.78

Answer:

The area of the parallelogram is 247 inches^2 to the nearest square inch

Step-by-step explanation:

This question asks us to calculate the area of a parallelogram given the sides and an acute angle.

Please check attachment for diagrammatic representation of the said parallelogram.

Mathematically, the area of the parallelogram can be calculated using the formula;

A = ab sin θ

where a and b refers to the length of the two sides and θ being the acute angle

Substituting these values, we have

A = 20 * 14 * sin 62

A = 280 sin 62 = 247.23 which is 247 inches^2 to the nearest square inch
