200 * 33/40 = 165 owns phones
165 * 10/11 = 150 owns phones and MP3 player

Therefore 3/4 owns both and
165 owns only phones

The average mass of an ant is approximately 3 × 10 − 3 grams. The average mass of a giraffe is approximately 2 × 10 3 kilograms.

Vika [28.1K]

Given that average mass of an ant $= 3 \times 10^{-3}$ grams.

Given that average mass of a giraffe $= 2 \times 10^{3}$ Kilograms.

Now we have to find about how many times more mass does a giraffe have than an ant. Before carring out any comparision, we must make both units equal.

Like convert kilogram into gram or gram into kilogram.

I'm going to convert kilogram into gram using formula

1 Kg = 1000 g

So the average mass of a giraffe $= 2 \times 10^{3} *10^3$ grams.

Now we just need to divide mass of giraffe by mass of ant to find the answer.

$\frac{2 \times 10^{3} *10^3 }{3 \times 10^{-3} }$

$= \frac{2 \times 10^{3} *10^3 *10^{3}}{3 }$

$= \frac{2 \times 10^{3+3+3}}{3 }$

$= \frac{2 \times 10^9}{3 }$

$= \frac{2}{3 } \times 10^9$

=666666666.667

Hence final answer is $\frac{2}{3 } \times 10^9$ which is approx 666666666.667.

How do i make 1\2x-y=4 into slope intercept form

kari74 [83]

Simple, since you want to find y, in y=mx+b form, move everything to the other side.

1/2x-y=4

Move 1/2x

1/2x-y=4
-1/2x -1/2x

Making it look like,

-y=4-1/2x

Divide by the negative 1 in front of the y,

-y=4-1/2x
/-1 /-1

y=-4+1/2x

or

y=1/2x-4

Thus, this written in y=mx+b form, y=1/2x-4.
