Answer:

338 tiles

Step-by-step explanation:

First, convert the measurements of the kitchen from feet to inches by multiplying each measurement by 12.

102 * 12 = 1224 18 * 12 = 216

Now multiply these answers together.

1224 * 216 = 264,384 square inches

Now find the area of the vinyl tiles.

28 * 28 = 784 square inches

Now find how many 784 square inch tiles are needed to cover a 264,384 square inch kitchen.

264,384 / 784 = 337.224

Since you can't buy part of a tile, round your answer up.

338 tiles

Answer for 6x-31=11x+64

PIT_PIT [208]

6x - 31 = 11x + 64
6x cancels out and you take 6x away from 11x
-31 = 5x + 64
64 cancels out and you take 64 away from -31
-95 = 5x
Divide both sides by 5
-19 = x

825/3 = 275 which is how many miles she drove in January.

275*4= 1100 which is how many miles she drove in February.

Correct notation? im lost someone help?

joja [24]

The correct notation for the $\sqrt{-100} -84$ is -84+10i.

Answer: Option B.

<u>Step-by-step explanation:</u>

A square root is the inverse function of exponential function.

Square root of positive numbers either result natural numbers or rational numbers.

But the square root of negative number is not possible. So that an imaginary number system was founded to represent the square root of negative number.

It is represented with i with the result of the solution of the square root.

Here the given problem is $\sqrt{-100} -84$ ,

-84 will remain the same and let us convert $\sqrt{-100}$ .

$\sqrt{-100}$ can be written as $\sqrt{100}$ × $\sqrt{-1}$ .

$\sqrt{100}$ = 10

$\sqrt{-1}$ = i.

∴ $\sqrt{-100}$ =10i.

The correct notation for the $\sqrt{-100} -84$ is -84+10i
