Yes, you are absolutely correct. It seems like Mike knows that paint and the size of the rooms are directly proportional i.e., the larger the size of the room, the more paint it requires. Mike is smart.

If this is what you are looking for.

What value can be written on the blank line to make the expressions equivalent
Gala2k [10]
<span>The expression is missing from the question, but here is the given expression which I got from a similar question.

48 + 54 = ___ ´ (8 + 9)

Theleft-hand side of the equation is:
                                                             48 + 54 = 102
Now the right-hand side of the equation:
                                                                    A </span>× (8+9) = Right-hand side
                                                                    A × (8+9) = 102
Solving for the unknown variable A,
                                                                    A × 17 = 102
Dividing by 17 on both sides,
                                                A × 17 ÷ 17 = 102 ÷ 17
                                                         A × 1 = 6
                                                              A = 6

Hence,
           48 + 54 = 6 x (8 + 9)

The machine could punch out 500 plastic pterodactyls in 20 minutes at that rate how many could it punch out in 1 and 1/2 hours
bagirrra123 [75]
I would find it easiest to reduce the number to minutes, like this: 500 in 20 minutes would be 500 divided by 20 = 25 pteradactyls /min.

There are 90 minutes in an hour and a half, so 25 x 90 = 2,250 pteradactyls in 1 1/2 hours.

What is vaule of y when x=4'5
Degger [83]

Answer:

y = 2.096 or y = \frac{2\sqrt5+6}{5}}

Step-by-step explanation:

Given

y = \frac{4}{x} + \sqrt x + 0.2  - 5x

x = \frac{4}{5}

Required

Find y

y = \frac{4}{x} + \sqrt x + 0.2  - 5x

Substitute x = \frac{4}{5}

y = \frac{4}{4/5} + \sqrt{4/5} + 0.2 - 5 * 4/5

y = 5 + \sqrt{4/5} + 0.2 - 4

Collect like terms

y = \sqrt{4/5} + 5  + 0.2 - 4

y = \sqrt{\frac{4}{5}} + 1.2

Split the surd

y = \frac{\sqrt4}{\sqrt5}} + 1.2

y = \frac{2}{\sqrt5}} + 1.2

Rationalize

y = \frac{2\sqrt5}{\sqrt5*\sqrt5}} + 1.2

y = \frac{2\sqrt5}{5}} + 1.2

Take LCM and add

y = \frac{2\sqrt5+1.2*5}{5}}

y = \frac{2\sqrt5+6}{5}}

or solve as:

y = \frac{2*2.24+6}{5}}

y = \frac{10.48}{5}

y = 2.096
