Please help me guys this is really important to me

Mathematics
1 answer:

Answer:

86 x 12 + P = 1,150

Step-by-step explanation:

The office manager bought 86 boxes, which each have 12 reams of paper inside, so the total number of reams of paper in the 86 boxes is 86 x 12 (86 boxes of 12 reams of paper).

86 x 12 = 1,032, so we know we haven't got enough reams yet, because 1,032 is less than 1,150.

'P' represents the number of reams of paper we still need to reach 1,150.

Therefore, if we add P reams to 1,032 reams, we will have 1,150 reams.

Answer:

9m

Step-by-step explanation:

The surface area of a cube is given by

SA = 6s^2  where s is the side length

We know the surface area is 486 and the side length is z

486 = 6z^2

Divide each side by 6

486/6 = 6z^2/6

81 = z^2

Take the square root of each side

sqrt(81) = sqrt(z^2)

9 = z

Each side has a length of 9m

pshichka [43]

Step-by-step explanation:

Y = 389.10 - 14.6 X.

Here when X increases Y decreases so correlation coefficient is negative .

correlation coefficient = - √ .657

Make x the subject of the formula: <br> Y=3x^2+4
Rzqust [24]

Answer:

see explanation

Step-by-step explanation:

given

y = 3x² + 4 ( isolate the term in x by subtracting 4 from both sides )

y - 4 = 3x² ( divide both sides by 3 )

\frac{y-4}{3} = x² ( take the square root of both sides )

\sqrt{\frac{y-4}{3} } = x, or

x = \sqrt{\frac{y-4}{3} }
