Answer:

1. 0.025.
2. 0.10416666666
3. 0.02222222222
4. 1/8.
5. 0.02857142857
6. 3/10
7. 0.15277777777
8. 0.15625

Step-by-step explanation:

1/5 / 8 = 0.025
5/8 / 6 = 0.10416666666
2/10 / 9 = 0.02222222222
1/4 / 2 = 1/8.
1/5 / 7 = 0.02857142857
9/10 / 3 = 3/10
11/12 / 6 = 0.15277777777
5/8 / 4 = 0.15625.

A 10-metre long pipe is cut into 2 pieces. One piece is 5 times the length of the other piece. Find the length of each piece, en

elena55 [62]

9514 1404 393

Answer:

1.67 m, 8.33 m

Step-by-step explanation:

If the ratio of lengths is 1 : 5, then the ratio of the shortest length to the total is ...

1 : (1+5) = 1 : 6

The shortest length is (10 m)×(1/6) = 1.67 m. The longer length is 10 -1.67 = 8.33 m.

The lengths of the pieces are 8.33 m and 1.67 m.

In two or three sentences explain how you would solve for the real solutions of the following equation: please help asap!!

g100num [7]

the real solutions for the equation $x^{3}=-64$ are -

$x=4,2+-2\sqrt{3i}$

Step-by-step explanation:

$x^{3}$ = $- 64$

$x^{3} +64$ = 0

We can write 64 as $4^{3}$

$x^{3}$ + $4^{3}$ = 0

using the identity ( $x^{3}+y^{3} = (x+y)(x^{2} -xy+y^{2} )$ )

we get,

= $(x+4) (x^{2} -x*4+4^{2} )$

= $(x+4)(x^{2} -4x+16)$ ....................(1)

solving the quadratic equation ,

$x^{2} -4x+16$ =0

solutions of this quadratic equation can be obtained by

$x=-b +- \sqrt{b^{2}-4ac } /2a$

let use y for factors

$x=-(-4x)+-\sqrt{(-4x^{2} )-4*x^{2} *16} / 2*x^{2}$

$x=4x+-\sqrt{16x^{2} -64x^{2} } /2x^{2}$

$x=4+-\sqrt{16-64}/2$

$x=4+-4\sqrt{3i} /2$

<u /> $x=2+-2\sqrt{3i}$ ..................(2)

from the equation 1 we have,

$x-4=0$

which gives solution $x=4$

and from equation 2 we got $x=2+-2\sqrt{3i}$

so the real solutions for the equation $x^{3}=-64$ are -

$x=4,2+-2\sqrt{3i}$

A company plans on selling MP3 players for $120. To make the MP3 players, a cost estimator determined it costs the company $1500

lana66690 [7]

Answer:

6000

Step-by-step explanation:

Each mp3 sells at $120 per mp3 player multiply that by 100 its $12000

It cost them $45 per mp3 to be made multiply that by 100 its $4500 then add the $1500 for the week and its $6000

$12000-$6000=$6000

They make a profit of $6000 in a week
