Answer:
4,400 = 44 * 100
44 = 2 * 2 * 11
100 = 2 * 2 * 5 * 5
prime factors = 2 * 2 * 2 *2 * 5 * 5 * 11
Step-by-step explanation:
What’s the side lengths of the thing ?
Answer:
$115.2
Step-by-step explanation:
Step one:
Given data
A store used to sell an MP3 for $72 and we are told that this 50% of the wholesale price.
Therefore the wholesale price is
72*2= $144
Required:
The special sales cost at 20% discount
Step two:
We are told that the special sale is at a 20% discount on the wholesale
= 20/100*144
=0.2*144
=$28.8
Therefore the special sales price is
= 144-28.8
=$115.2
Answer:
y=8.25x-15
Step-by-step explanation:
From the information provided, the algebraic expression will need to indicate that your earnings during the first week, y, would be equal to multiplying $8.25 for the number of hours, x, minus $15. According to that, the algebraic expression is:
y=8.25x-15
<7 = <5 vertical angles
<5 = <3 alternate interior angles are equal when the lines are parallel
<2 +<3 = 180 straight line ( complementary angles)
3x+20 + <3 = 180
subtract 3x+20 from each side
<3 = 180 -(3x+20)
<3 = 180 -3x-20
<3 =160 -3x
but from above
<3 also = <5 = <7 and <7 = 2x-10
160 - 3x = 2x-10
add 3x to each side
160 = 5x-10
add 10 to each side
170 = 5x
x = 34
substitute in x=34 to find angle 3
<3 = 160 -3x
<3 =160 -3(34)
<3 =58
to find angle 6
<7+<6 = 180
<7 =<3 = 58
58 + <6 = 180
subtract 58 from each side
<6 = 180 -58
<6 = 122
