Answer:

1.4\ gallons

Step-by-step explanation:

Step 1

Find the area of one wall

Multiply the high by the wide

so

A=7*8=56\ ft^{2}

Step 2

Find the area of four walls

Multiply the area of one wall by four

A=4*56=224\ ft^{2}

Step 3

By proportion calculate how many gallons of paint are needed

\frac{1}{160} \frac{gallon}{ft^{2}}=\frac{x}{224} \frac{gallons}{ft^{2}}\\ \\x=224/160\\ \\x=1.4\ gallons

P partitions GR in ratio 2:4. GR is 36cm. How long is GP and PR?
Allushta [10]

Answer:

12 cm and 24 cm

Step-by-step explanation:

The line is divided in the ratio 2 : 4 = 2x : 4x ( x is a multiplier )

The sum is therefore

2x + 4x = 36

6x = 36 ( divide both sides by 6 )

x = 6

Thus

GP =  2x = 2 × 6 = 12 cm

PR = 4x = 4 × 6 = 24 cm

PLEASE HELP!!This is joshs solution for the equation x^2-6x-7=0: x^2-6x-7=0
iren [92.7K]

Answer:

  no. see below

Step-by-step explanation:

This much of Josh's working is correct:

  x^2-6x=7

  x^2-6x+9=7+9

  (x-3)^2=16

At this point Josh apparently overlooked the fact that he needed to take the square root of both sides of the equation. Had he done that, he would have ...

  x -3 = ±4

  x = 3+4 . . . or . . . 3 -4

  x = 7 or -1

_____

Josh reported values of x that would match ...

  x -3 = ±16

He <em>violated the equal sign</em> by taking the square root on the left, and multiplying by ±1 on the right. Doing different operations on the two sides of the equation will mean the value of x is changed to something other than what you're looking for.
