<span>Even numbers on a dice: 2,4,6 = 1/2 chance.

Numbers less than 6 on a dice: 5/6 chance. 1/2 + 5/6 = 8/6.

8/6 is impossible so we'll take it down to 1. There will ALWAYS be an even number, or a number less than 6.

The answer is 1.</span>

5/6 because there are 5 possible possibilities and 6 numbers on the dice I'm assuming that the dice has 6 faces.

Answer:

${x}^{2} + 3x - 10$

Step-by-step explanation:

$(x + 5)(x - 2)$

utilise the Foil method to expand brackets:

F - mulply the first terms (x and x)

O - multiply the outside terms ( x and -2)

I - multiply the inside terms (5 and x)

L - multiply the last terms (5 and -2)

Then add them as following:

${x}^{2} - 2x + 5x - 10$

Then combine like terms:

${x}^{2} + 3x - 10$

Solve:

7,710 ÷ 12 = 642.5‬0

This means that he'll pay $642.5‬0 a month.

Answer:

$642.5‬0

The floor of the restaurant is a square of sides 28m. The floor is covered with square tiles of sides 40m. Calculate the total n

lisov135 [29]

Answer:

196000 tiles.

Step-by-step explanation:

The 28 m is 2800 cm. So a 28 x 28 meter square would be 2800 x 2800 centimeter square.

The tiles are 40 cm.

If you divide 40 from (2800 x 2800). (2800 x 2800) ÷40 = 196000

So 196000 tiles.

I'm not entirely sure if that's correct, but if it helps that's awesome.
