Yani is creating a mural on a patio that measures 3 m long by 2 m wide. He is using 1 cm by 1 cm tiles. How many tiles will he need to use for the mural to cover the whole patio?
Answers
Answer: 60,000 tiles
Step-by-step explanation:
First find the area of the mural.
= 3 * 2
= 6 m²
The find the area of the tiles.
= 1 * 1
= 1 cm²
I m² = 10,000 cm²
There is therefore:
= 6 * 10,000
= 60,000 cm²
That is the area that needs to be covered in cm²
Seeing as each tile is 1cm², the number of tiles needed is:
= 60,000 / 1
= 60,000 tiles
Answer: the answer is 60,000 tiles
by the way that kinda seems like a lot of tiles to place like how long is that gonna take.

A farmer sells 8.4 kilograms of pears and apple at the market. 1/4 of this weight is pears and the rest is apples. How much kilograms of apples did she sell at the market
Answers
Answer:
[tex]Weight = 6.3 kg[/tex]
Step-by-step explanation:
Given
[tex]Total = 8.4kg[/tex]
[tex]Pears = \frac{1}{4}[/tex]
Required
Determine the weight of apples
First, we calculate the fraction of apple.
[tex]Apple = 1 - Pears[/tex]
[tex]Apple = 1 - \frac{1}{4}[/tex]
Take LCM
[tex]Apple = \frac{4-1}{4}[/tex]
[tex]Apple = \frac{3}{4}[/tex]
The weight is then calculated as:
[tex]Weight = \frac{3}{4} * Total[/tex]
[tex]Weight = \frac{3}{4} * 8.4kg[/tex]
[tex]Weight = \frac{3* 8.4kg}{4}[/tex]
[tex]Weight = \frac{25.2kg}{4}[/tex]
[tex]Weight = 6.3 kg[/tex]
Hence, the apples weigh 6.4kg

Answer:
x = 98 degrees
Step-by-step explanation:
A heptagon has a total of 900 degrees for the interior angles. Add up all the angles and then subtract from 900 to find x.
146+122+142+140+110+142 = 802.
900-802 = 98
Answer:
x = 98
Step-by-step explanation:
This shape has 7 sides. Using the formula n - 2 we can get the number of triangles. n represents the number of sides.
n - 2 = 5
All triangles have 180 degrees, so multiply 180 by the number of triangles (5).
180 × 5 = 900
The total number of degrees in this shape is 900. Adding the other angle measures and then subtracting them from 900 gives us x.
146 + 122 + 142 + 140 + 110 + 142 = 802
900 - 802 = 98.
x = 98

what is the answer of this question?
Answers
9514 1404 393
Answer:
970
Step-by-step explanation:
It turns out that the radical terms cancel, so the result is an integer. You can find the integer value using your calculator. It is ...
(5 +2√6)³ +1/(5 +2√6)³ = 970
_____
The cube of 'a' is ...
(5+2√6)³ = 5³ +3·5²·2√6 +3·5·(2√6)² +(2√6)³
= 125 +3·50√6 +3·120 +48√6
a³ = 485 +198√6
The reciprocal of this is ...
b³ = 1/a³ = 1/(485 +198√6) = (485 -198√6)/(485² -6·198²) = (485 -198√6)/1
b³ = 485 -198√6
Then the sum is ...
a³ +b³ = (485 +198√6) +(485 -198√6) = 970
