Answer:

(9x2 + 4x - 6) + (5x3 + 2x2 - 2x - 5) = 5x3 + 11x2 + 2x - 11

So, if, say 9 - 5 = 4, 9 - 4 = 5, right?

(5x3 + 11x2 + 2x - 11) - (5x3 + 6x2 + x - 16) = 5x2 + x + 5

You have to divide the number you got with the number that you can get out of. (36/40=0.9) and then convert the decimal to a percentage

Answer:

n = 2

Step-by-step explanation:

Given nx + y = 4, if we rearrange in slope-intercept form: y = -nx + 4

This means that the y-intercept is 4. Point "A" is the y-intercept, which would make OA = 4, and OB = 1/2(4) = 2.

We can now solve for n. The slope here is "-n", also represented by rise/run or OA/-OB = 4/-2 = -2.

-n = -2,

n = 2

Answer:

Each additional cup is 1 centimeter.

Step-by-step explanation:

We know this because we can see the height on the graph. For each number of cups increased (y-axis), 1 centimeter in height increases as well.

Therefore, we can say that each additional cup is 1 centimeter.

Answer:

Step-by-step explanation:

It can be shown that all four sides of this figure have the same length.  This, in turn, is the definition of a rhombus.

The pair of angles are acute angles.

The correct option is none of these.

The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.

Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.

We have,

The pair of angles of 30 and 30 are equal in measure.

But they are not adjacent, as they do not share a common vertex and a common side.

They are also not complementary, as complementary angles add up to 90 degrees, and 30 + 30 = 60.

Similarly, they are not supplementary, as supplementary angles add up to 180 degrees, and 30 + 30 = 60.

Therefore,

The pair of angles are none of the given options.

Answer: the weight in kilograms is 9.76kg

Step-by-step explanation:

1 meter of length of rope = 800 g

12.2 meters of the rope= (12.2meters x 800g)/ 1 meter=9760grams

We know that 1000 g = 1kg

 9760 grams = 9760/1000=9.76 kilograms

Ya just multiply the percent by the amount of years and add it to the original amount of money in the account.

Cost of a television Ms. Singh wants to buy = £840

Ms. Singh's weekly wage = £300

Money she saves each week :

= 40% of her weekly wage

[tex] =\tt 40\% \: of \: 300[/tex]

[tex] = \tt \frac{40}{100} \times 300 [/tex]

[tex] =\tt \frac{40 \times 300}{100} [/tex]

[tex] =\tt \frac{12000}{100} [/tex]

[tex]\color{plum} = \tt£120[/tex]

Thus, Ms. Singh's weekly savings = £120

Number of weeks in which she will be able to buy a TV :

[tex] = \tt \frac{840}{120} [/tex]

[tex]\color{plum} =\tt 7 \: weeks[/tex]

Therefore, Ms. Singh will be able to buy a TV from her savings in 7 weeks.

Answer:

1.) Scale factor from the actual flower garden to the scale drawing = 20 : 1

2.) Dimensions of the flower garden in the new scale drawing = 7.5 inches × 11.25 inches

3.) Scale factor from the actual flower garden to the new scale drawing = 8:1

Step-by-step explanation:

Given - Penny’s backyard contains a flower garden. The dimensions of the

             actual garden are 5 feet by 7½ feet. A scale drawing of the flower

             garden is 3 inches by 4.5 inches.

To find - 1. What is the scale factor from the actual flower garden to the

                  scale drawing?

              2. If the drawing is enlarged by a scale factor of 5/2, what would    

                  be the dimensions of the flower garden in the new scale

                  drawing?

              3. What is the scale factor from the actual flower garden to the

                   new scale drawing?

Proof -

As we know that,

1 feet = 12 inches

⇒5 feet  = 5×12 = 60 inches

  7½ (= [tex]\frac{15}{2}[/tex]) feet = [tex]\frac{15}{2}[/tex]×12 = 90 inches

∴ we get

The dimensions of the actual garden is 60 inches by 90 inches.

1.)

As,

[tex]\frac{60}{3} = \frac{20}{1} = 20 : 1[/tex]

[tex]\frac{90}{4.5} = \frac{900}{45} =\frac{20}{1} = 20 : 1[/tex]

So,

Scale factor from the actual flower garden to the scale drawing = 20 : 1

2.)

As given,  If the drawing is enlarged by a scale factor of 5/2

⇒Dimensions of flower garden = 3×[tex]\frac{5}{2}[/tex] inches by [tex]4.5 (\frac{5}{2})[/tex] inches

                                                    = 7.5 inches by 11.25 inches

∴ we get

Dimensions of the flower garden in the new scale drawing = 7.5 inches × 11.25 inches

3.)

Scale factor from the actual flower garden to the new scale drawing = [tex]\frac{60}{7.5}[/tex] = [tex]\frac{600}{75} = \frac{8}{1} = 8 : 1[/tex]

Answer:

£48

Step-by-step explanation:

£25 = 450 rubles

We need to know how many rubles you can get from £1.

£25 = 450

£ = 450/25

£ = 18

So, with £1 you get 18 rubles.

To know how many £'s you would need for 864 rubles, you need to divide 864 by 18.

£ = 864/18

£ = 48
