Answer:

D. 29

Step-by-step explanation:

First, let's make things a bit easier for ourselves and convert mixed numbers to improper fractions

[tex]-\frac{10}{3}* -\frac{87}{10}[/tex]

Next, we check for numbers that can cancel out. In this case, we have 10.

[tex]-\frac{1}{3}*-\frac{87}{1}[/tex]

Because negatives cancel out, we get

[tex]\frac{87}{3}[/tex]

when we multiply.

Fractions just mean division, so we divide 87 by 3 and get

Answer:

radius = 9

Step-by-step explanation:

The equation of the circle centred at the origin is

x² + y² = r² ( where r is the radius )

Given

x² + y² = 81, then

r² = 81 ( take the square root of both sides )

r = [tex]\sqrt{81}[/tex] = 9

Answer:

Q1, x=2 and all sides equal 8

Answer:

The better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.

Step-by-step explanation:

To find which is the better deal, you have to determine which one offers a lower unit price by dividing the price of each package by the number of balls in the pack:

$4.47/12=$0.37

$14.46/18=$0.80

According to this, the answer is that the better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.

Answer:

There would be 210 calories in a 3/4 cup serving.

Step-by-step explanation:

1/2 of 140 = 70

70 = 1/4

70 x 3 = 210 = 3/4

I hope this helped you! If it did, please consider pressing thanks, rating my answer, and marking as Brainliest. It would be a big help! Have a great day! :)

Based on the number of calories in 1/2 cups, the number of calories in 3/4 cups is 210 calories.

You can use direct proportion to solve for this by assuming that the calories in 3/4 cups is x:

1 / 2          :         140 calories

3 / 4          :        x

Cross multiplying would give:

1/2x = 105

x = 105 ÷ 1/2

x = 210 calories

In conclusion, there would be 210 calories in 3/4 cups.

Answer:

This would be 26 x + 189

Answer:

Step-by-step explanation:

Let the width of the margins as x.

So, we subtract 'x' width on each side of the paper.

So, length = 26-x-x= 26-2 x

Width = 27-x-x=27-2 x

Now, it is given printed area is 360

We can set up equation using length x width = Area

(26-2 x)(27-2 x) = 360

Multiply the left side using FOIL method,

702 -52  x-54 x+4 x^2 =360

Combine like terms

702-106x+4x^2=360

Subtract both sides 360

4x^2-106x+342 =0

Let's divide both sides by 2 to simplify

2x^2 -53x+171=0

Let's use quadratic formula to solve.

Answer:

Step-by-step explanation:

the bat is 12. the pumpkin is 5. and the weird looking thing is 14

14 plus 14 plus 12 is 40

12 minus 5 is 7

5 plus 14 is 19

14 minus 5 plus 12 is 21

Answer:

  21

Step-by-step explanation:

Green bat:   x

Purple bat:   y

  Pumpkin:   z

Given:

  2x + y = 40

  y - z = 7                ===>      y = 7 + z

  z + x = 19             ===>       z = 19 - x

Substitution to find green bat x:

  2x + y = 40

  2x + (7 + z) = 40

  2x + 7 + z = 40

  2x + 7 + (19 - x) = 40

  2x + 7 + 19 - x = 40

  x + 26 = 40

  green bat:  x = 14

Substitution to find pumpkin z:

  z + x = 19

  z + (14) = 19

  z + 14 = 19

  pumpkin:  z = 5

Substitution to find purple bat y:

  y - z = 7

  y - (5) = 7

  y - 5 = 7

  purple bat:  y = 12

Solve for x - z + y:

  14 - 5 + 12 = 21

Answer:

Step-by-step explanation: Convert fraction (ratio) 35 / 25 Answer: 140%

The number 35 is 140% of the given number 25.

A fraction or proportion expressed as a percentage of 100 is called a percentage. "%" is used to represent it. Frequently, percentages are employed to indicate relative values, compare amounts, and represent components of a total.

To find out what percent 35 is of 25, we can use the following formula:

Percent = (Part / Whole) * 100

Identify the part and the whole. In this case, 35 is the part and 25 is the whole.

Substitute the values into the formula:

Percent = (35 / 25) x 100

Simplify the expression inside the parentheses:

Percent = 1.4 x 100

Multiply the simplified expression by 100:

Percent = 140

Therefore, 35 is 140% of 25.

Step-by-step explanation:

In order to find how many students stay back for Chess Club, we want to find 12% of 800.

To do this, we can set up a percentage proportion.

[tex]\frac{12}{100} = \frac{x}{800}[/tex]

We can now solve for x by cross multiplying.

Answer:

A edge 2021

Step-by-step explanation:

Point A Represents (3,-5π/3).

The distance from a point to the origin (r) and the angle this line makes with a fixed line (Θ) are the two coordinates that specify where a point is located in a plane.

The radius of circle is 3 units.

The angle in the polar coordinate measured clockwise is considered negative and measured anticlockwise as positive.

In order to get the position of the angle from the x-axis the angle should be added by 2π as

Θ = 2π-5π/3

Θ = π/3

The angle is calculated clockwise.

From the diagram point, A represents the angle  π/3.

Thus, the Point A Represents (3,-5π/3).

Answer:

The profit decreases by $ 375 for every $ 1 increase in the selling price.

Step-by-step explanation:

From the definition of the secant line we get that the average rate of change of [tex]P(x) = -0.015\cdot x^{2}+1.2\cdot x -11.5[/tex], where [tex]x[/tex] is the selling price of the product, measured in dollars per unit, is:

[tex]r = \frac{P(55)-P(50)}{55-50}[/tex] (1)

Now we evaluate the function at each bound:

x = 50

[tex]P(50) = -0.015\cdot (50)^{2}+1.2\cdot (50)-11.5[/tex]

[tex]P(50) = 11[/tex]

x = 55

[tex]P(55) = -0.015\cdot (55)^{2}+1.2\cdot (55)-11.5[/tex]

[tex]P(55) = 9.125[/tex]

Then, the average rate of change is:

[tex]r = \frac{9.125-11}{55-50}[/tex]

[tex]r = -0.375[/tex]

Hence, the profit decreases by $ 375 for every $ 1 increase in the selling price.

The statements that best interprets the average rate of change from x = 50 to x = 55 is (b) The profit decreases by $375 for every $1 increase in the selling price.

The profit function is given as:

[tex]P(x) = -0.015x^2 + 1.2x - 11.5[/tex]

Calculate P(x), when x = 50.

So, we have:

[tex]P(50) = -0.015(50)^2 + 1.2(50) - 11.5[/tex]

[tex]P(50) = 11[/tex]

Calculate P(x), when x = 55.

So, we have:

[tex]P(55) = -0.015(55)^2 + 1.2(55) - 11.5[/tex]

[tex]P(55) = 9.125[/tex]

The average rate of change from x = 50, to 55 is then calculated using:

[tex]m = \frac{P(55) - P(50)}{55-50}[/tex]

So, we have:

[tex]m = \frac{9.125 - 11}{55-50}[/tex]

[tex]m = \frac{-1.875}{5}[/tex]

Divide

[tex]m = -0.375[/tex]

The function is in 1000 units.

So, we have:

[tex]m = -0.375\times 1000[/tex]

[tex]m = -375[/tex]

-375 implies a decrease of $375 for every $1 increase in sales

Hence, the correct statement is (b)
