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:

17. x=11  18. x=18

Step-by-step explanation:

For 17, 14x-25=129, add 25 to 129 to get 154, then divide 154 by 14x to get x=11. The conditional for 17. would be "If J║K then alternate interior angles are congruent.

For 18. 2x-8+9x-10=180, combine like terms to get 11x - 18 =180, add 18 to 180 to get 198 than divide 198 by 11x and get x = 18. Converse statement would be, "If J║K then consecutive interior angles are supplementary.

Answer:

She would need to order 11.5 pizzas. But of course she wouldn't order 11.5 so she'll just round up and order 12 pizzas.

Step-by-step explanation:

Take 4 pieces of pizza for each person and multiply that by how many people there are in this case 23. The answer would be 92 pieces of pizza would be needed to feed all of the 23 people. So you take 92 and divide it by 4 because each person gets 4 slices and the answer you get is 11.5. If the question is a multiple choice and it gives you the option of 11.5 then that's the answer but if its a fill in then round up to 12 pizzas because if not there will not be enough pizza for everyone.

Hope this helped! :)

Answer:

Step-by-step explanation:

length=1 m

base of triangle=10 m

height=5m

volume= 1/2×10×5×1=25 m cube.

slant height l=√(5²+5²)=√50=5√2

slant surface area=2[5√2×1]=10√2

area of front and back=2×1/2(10×5)=50

total surface area=50+10√2≈50+14.14≈64.14 m²

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

Answer:

Y=-2

Step-by-step explanation:

Hope that helps you

Answer:

y=-2

Step-by-step explanation:

first, you have to leave y alone so you have to add 2 on both sides to delete -2

y-2+2=-4+2

now -2+2=0 so that's gone and -4+2 is -2

Now you have the answer UvU

y=-2

Answer:

y = 3[tex]\sqrt{7}[/tex]

Step-by-step explanation:

The 2 right triangles inside the right triangle are similar, then ratios of corresponding sides are equal, that is

[tex]\frac{y}{9}[/tex] = [tex]\frac{7}{y}[/tex] ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = [tex]\sqrt{63}[/tex] = 3[tex]\sqrt{7}[/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

Answer:

x=3

Step-by-step explanation:

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:

75-9d

Step-by-step explanation:

Hello,

The Answer to the question is 75-9d let me explain why,

you are asking, how much money is leftover. For me to get that I need to know that for every book it cost "d" dollars.

You know you have $75, and you need 9 books, we don't know how much they cost but we don't really need to.

75 - 9d

75 is the total. You need to subtract it by how many books your buying, 9.

The books are d amount of dollars, so we put 9d so that we know that for every 1 book it cost d amount so technically 9 is the amount of books times d, how much 1 book costs

Hope you can understand, I was having some trouble finding a way to explain it so my bad.

Also, I haven't done that in a while so sorry if I'm wrong
