celeste wants to have her hair cut and permed and also go to lunch. she knows she will need 59$. the perm cost twice as much as

miv72 [106K]

Let's first start off with an equation to represent Celeste's budget:
$h + p + l = 59$
Where:
'h' is the money in dollars that she needs to get her hair cut
'p' is the money in dollars that she needs to get her hair permed
'l' is the money in dollars that she needs for lunch

Now let's simplify this equation using the information that was given:
$l = 5$ *This must be true since it is told that she needs $5 for lunch
$0.5p = h$ *This is because the perm costs twice as much as the hair cut

Our new/updated equation is:
$0.5p + p + 5 = 59$

This is much easier to solve, let's rearrange and solve for 'p':
$0.5p + p = 59 - 5$
$1.5p = 54$
$p = 36$

Therefore the perm costs $36

I hope this helps! Let me know if you have any further questions.

Derive the equation of the parabola with a focus at (−2, 4) and a directrix of y = 6. Put the equation in standard form.

zlopas [31]

Sketch a graph so you can find the vertex and determine if the parabola is horizontal or vertical. When i graph (-2,4) and then y=6, I find the middle is (-2,5) so that will be the vertex. The distance to the vertex is -1 so 4p=-4.
My formula is (x-h)^2=4p(y-k), now just plug in numbers. You should end up with (x+2)^2=-4(y-5).
Some instructors want you to write (y-k)=1/(4p)(x-h)^2 which is the same thing, so check to see which one you should be using.

Basha's favorite board game has a spinner with nine congruent sections. The spinner has 2 red sections, 3 blue sections, and 4 g

kumpel [21]

Answer:

2/27

Step-by-step explanation:

Step one:

given data

Sample space

2 red sections,

3 blue sections, and

4 green sections

Sample size

2+3+4= 9

Required

The probability of Basha spinning a red on her first spin and a blue on her second spin

Step two:

On the first spin, spinning a red= 2/9

On the second spini, spinning a blue= 3/9= 1/3

Hence, The probability of Basha spinning a red on her first spin and a blue on her second spin= 2/9*1/3= 2/27
