If £25 = 450 rubles, how many £ are in 864 rubles?

Answers

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

Ms Singh wants to buy a new television that costs £840
Each week, Ms Singh receives a wage of £300
She saves 40% of her wage each week.

weeks
Some student

Answers

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.

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

Classify the pair of angles.

O adjacent
O complementary
O supplementary
Onone of these

Answers

This is going to be none of these? For me it’s an acute but let me know what you think

The pair of angles are acute angles.

The correct option is none of these.

What is an angle?

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.

A rope weighs 800 grams per meter of length. What is the weight in kilograms of 12.2 meters of the rope?

Answers

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

Lin is solving the inequality 15−x<14. She knows the solution to the equation 15−x=14 is x=1 How can Lin determine whether x>1 or x<1 Is the solution to the inequality?

Answers

Answer:

x > 1

Step-by-step explanation:

Given the inequality ; 15 - x < 14

Since the solution to the equation 15−x=14 is x=1 ;

Then we obtain the value of x for which the inequality expression is true :

If x > 1 ; take x = 2

15 - 2 < 14

13 < 14 (true)

If x < 1 ; take x = 0

15 - 0 < 14

15< 14 (not true)

Hence, solution is x > 1

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 shown below.


1. What is the scale factor from the actual flower garden to the scale drawing?

Be sure to express your ratio in simplest form.




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? Express your dimensions in decimal form. Enter the smaller of your two lengths in the first answer box.

inches


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

Be sure to express your ratio in simplest form.

Answers

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]

Answers

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
