Answer:

Step-by-step explanation:

Let the total number of action figures = x

75% of x = 48

\dfrac{75}{100}*x=48\\\\Multiply \ by \ 100\\\\75*x =48*100\\\\Divide  \ by \ 75\\\\x=\dfrac{48*100}{75}\\\\\\x=16*4\\\\x= 64

Remaining action figures need to be collected = total figures - number of action figures I have

= 64 - 48 = 16

Number of weeks = 16 ÷ 2 = 8

It will take 8 weeks to collect 16 action figures.

The least amount of wrapping paper needed to wrap a cube-shaped gift is 150 square inches. How long is one side of the gift?
devlian [24]


Isn't the only thing you have to do is since a cube has 6 sides than you would have to do 150 divided by 6. If I am correct.

Brenda has two pieces of string, one 28 feet long and the other 42 feet long. For an art project, she wants to cut them up to pr
NeTakaya

Answer:

7 feet

Step-by-step explanation:

Length of one piece of string = 28 feet.

Length of the second string = 42 feet.

Since the number of required pieces was not given but many are required, the greatest length can be determined by;

If the maximum length is 7 feet, then:

the number of pieces from 28 feet long string = \frac{28}{7}

                                                      = 4

Also,

the number of pieces from the 42 feet lone string = \frac{42}{7}

                                                    = 6

Total number of 7 feet strings that she can make = 4 + 6

                                                    = 10

Since many pieces are required, the greatest length she can make is 7 feet. If she increase the length to 14 feet, the number of pieces would be 5 which limit the required number.

How would you solve this equation? Please show steps
Serhud [2]
Simple....

you have: 3x= \sqrt{12-12x}

So...first you know you're trying to find x..

But, you have a square root on one side...to remove this you'd have to square both sides--->>>

(3x)^{2} = \sqrt{12-12x}  ^{2}

Leaving you with....

9x^{2} =12-12x

Move the terms over and set it equal to zero.

-->>

9x^{2}+12x-12=0

Factor out a 3...

3( 3x^{2} +4x-4=0)

What multiplies to -12 and adds to 4?

6*-2=-12

6+-2=4

Leaving you with...

3(3x-2)(x+2)=0

Remember you're solving for 0....

3x-2=0

3x-2=0
    +2  +2

3x=2

\frac{3x}{3} = \frac{2}{3}

x=
\frac{2}{3}

Then-->>

x+2=0

x+2=0
  -2   -2

x=-2

Thus, your answer.
