Lynn is going to cover the floor with tiles.
Each tile is a rectangle of side 60 cm by 30 cm.
Each tile costs £4.25
Lynn has £400 to spend on tiles.
Show that she has enough money to buy all the tiles she needs. (*)
(5 Points)
300 cm
540 cm

Answers

Answer:

Please check explanations

Step-by-step explanation:

Firstly, we calculate the area of the floor

That is the product of the sides

= 300 * 540 = 162,000 cm^2

What is left is to calculate the area of a tile

Since the tile is also rectangular, the area of each tile will be;

60 * 30 = 1,800 cm^2

Since we have both areas, we can now get the number of tiles needed to cover the floor

We can get this by dividing the area of the floor by the area of a tile

This is;

162,000/1,800 = 90

This means that 90 tiles will cover the floor

The cost of a tile

is £4.25

The cost of 90 tiles will be ;

£4.25 * 90 = £382.5

from here, we can see that the £400 is more than £382.5

So we can conclude that she has enough to spend on tiles

A restaurant is making table cloths for their four round tables. Each table is a circle with a radius of 2 ft. Each table cloth needs to be 20% larger than the table surface.


How many whole table cloths can the restaurant get out of a piece of fabric with an area of 64 ft²?
Please help!!

Answers

Answer:

4

Step-by-step explanation:

Since it gives us the amount of area of material to use we know we want to find how many times we can divide it into tablecloths.  So now we need to find how much each tablecloth is.

so first it tells us that each table has a radius of 2 ft, so we find the area using that.  area of a circle is [tex]\pi r^2[/tex] so plugging in 2 ft we get 4π square feet or 12.56.

It also says that each tablecloth needs to be 20% bigger, so we find what 20% larger than 4π is.  to do this you do 4pi*1.2 = 4.8π = 15.072 square feet.

Now, how many tablecloths with areas of 15.072 square feet can be made from 64 square feet.  Hopefully it's obvious you divide.  so 64/15.072 = 4.25

Since we want whole tablecloths and that .25 is a remainder, 4 whole tablecloths can be made.

  ∠Y = 55°

Step-by-step explanation:

Complementary angles have a sum of 90°.

  ∠S + ∠Y = 90°

  (5∠Y -240°) +∠Y = 90°

A glassblower can produce several sets of simple glasses in about 3 hours. When the glassblower works with
an apprentice, the job takes about 2 hours. Write an equation that can be used to find the amount of time t, in
hours, it would take for the apprentice to make the same number of sets of glasses when working alone.

Answers

Using the together rate, it is found that it would take the apprentice 6 hours to make the same number of sets of glasses when working alone.

What is the together rate?

The together rate is the sum of each separate rate.

In this problem, the rates are:

Glassblower: 1/3.Apprentice: 1/x.Together: 1/2.

Hence, applying the equation for the together rate:

[tex]\frac{1}{2} = \frac{1}{x} + \frac{1}{3}[/tex]

[tex]\frac{x + 3}{3x} = \frac{1}{2}[/tex]

[tex]2x + 6 = 3x[/tex]

[tex]x = 6[/tex]

It would take the apprentice 6 hours to make the same number of sets of glasses when working alone.
