Answer:
25% off
Step-by-step explanation:
First, find 90/120, which is 0.75. Now, since the phone is not 75% off, you just find 100-75, which gives you 25%.

Find the missing angle measure. PLEASE HELP ASAP
Answer:
Angle 1 is 57 degrees
Angle 3 is 57 degrees
Angle 4 is 123 degrees
Step-by-step explanation:
Cause a straight line is 180 degrees and if angle 2 is 123 degress then angle 3 is 57 degrees and i got that by Subtracting 180-123 =57
Then for angles one you do the same maththat you do for finding angle 3
Then for angles 4 subtract 180-57=123

a polynomial function with rational coefficients has the given roots. find two additional roots -2i and square root of 10
Answer:
(-2)(100) or 10^2 is 100
Step-by-step explanation:
(x -2)(x+100) =x
Additional roots of polynomial function P(x) with rational coefficients are (2i) and (- √10).
What is conjugate of complex number?
" If z = a +bi be the given complex number, then its conjugate is represented by [tex]\bar{z}[/tex] = a -bi , where real parts remain same only imaginary part get changed with opposite sign."
Theorem used
Conjugate Root theorem
Complex conjugate root theorem states that if P(x) is a polynomial in one variable with real coefficient , for P(x) if one root is a + bi with real numbers a and b then its conjugate that is a - bi is also another additional root of P(x).
According to the question,
Two given roots of polynomial function with rational coefficients are -2i and √10.
As per Conjugate root theorem,
Here one root is 0 - 2i then other root is its conjugate 0 + 2i
Also one root is 0 + √10 then another root is 0 - √10.
Therefore, two additional roots are 2i and -√10.
Hence, additional roots of polynomial function P(x) with rational coefficients are (2i) and (- √10).

Equation
(3x - 1) * 3 = 12*(x -2) Remove the brackets.
Solution
9x - 3 = 12x - 24 Add 24 to both sides.
9x - 3 + 24 = 12x - 24 + 24 Combine
9x + 21 = 12x Subtract 9x from both sides
9x - 9x +21 = 12x - 9x
21 = 3x Divide by 3
21/2 = 3x/3

What are two points that represent Justine's function for the yards left to hike in terms of the hours she's spent hiking?
Answer:
(0,320) and (4,0)
Step-by-step explanation:
The question has missing details. So, I've added the complete question as an attachment.
From the question, we understand that:
Justine started when Michael was 320 yards from the top.
This coordinate can be represented as (0,320)
0 represents the time Justine started and 320 represents the number of yards left.
Every minute, Justine covers 80 yards.
This implies that:
At 1 minute, Justine will have: (320 - 80) yards left
At 2 minutes, Justine will have: (320 - 80 - 80) yards left
At 3 minutes, Justine will have: (320 - 80 - 80 - 80) yards left
At n minutes, Justine will have (320 - 80n) yards left
So, possible coordinates are:
[tex](x_1,y_1) = (0,320)[/tex]
[tex](x_2,y_2) = (1,320-80*1) = (1,240)[/tex]
[tex](x_3,y_3) = (2,320-80*2) = (2,160)[/tex]
[tex](x_3,y_3) = (3,320-80*3) = (3,80)[/tex]
[tex](x_4,y_4) = (4,320-80*4) = (4,0)[/tex]
Answer:
Select any two pairs of values from the given table. But, for simplicity, it’s a good idea to select coordinates with integer values. So, two points that represent Justine’s function for the yards left to hike in terms of the hours she’s spent hiking are (1, 270) and (2, 150).

Stephanie is earning simple interest of 3.5% on her money each month. She currently has $1325 in her account. What will her balance be in 5 months?
Answer:
$1556.88
Step-by-step explanation:
Since Stephanie is earning simple interest and not compound interest, we can multiply her interest rate for each month by how many months we are calculating for.
0.035 x 5 = 0.175
Then multiply that by her current balance but change the 0 in front of the 0.175 to a 1 to reduce the number of steps we have to take. (It automatically adds what is earned in interest to her current balance.)
1.175 x 1325 = 1556.875

CAN SOMEONE PLEASE HELP THIS IS DUE AT MIDNIGHT (I’ll give brainlist)
Answer:
d° = 62°
e° = 90°
f° = 27°
g° = 27°
h° = 118°
j° = 62°
k° = 63°
Step-by-step explanation:
The relationship between the given angles are;
k° = 63° (Vertically opposite angles)
63° + f° = 90° (Given complementary angles)
∴ f° = 90° - 63° = 27°
f° = 27°
g° = f° (Vertically opposite angles)
∴ g° = f° = 27°
g° = 27°
e° + 63° + f° = 180° (The sum of angles on a straight equals 180°)
∴ e° = 180° - (63° + r°) = 180° - (63° + 27°) = 90°
e° = 90°
h° = 118° (Vertically opposite angles)
118° + d° = 180° (The sum of angles on a straight equals 180°)
∴ d° = 180° - 118° = 62°
d° = 62°
j° = d° (Vertically opposite angles)
∴ j° = d° = 62°
j° = 62°

Two families went to the movies. The Davis family paid $39 for 2 adult
tickets and 3 student tickets. At the same theater, the Tyler family paid $23
for 1 adult ticket and 2 student tickets. What is the price of a student
ticket?
Answer:
$7
Step-by-step explanation:
Let a be the price of the adult ticket and s be the price of the student ticket
That means that:
2a+3s=39
and
a+2s=23
Using elimination
-2(a+2s=23)
-2a-4s=-46
-2a-4s=-46
2a+3s=39
Eliminate a:
-s = -7 ; s = 7

Answer:
d = 9
Step-by-step explanation:
Given
1 = [tex]\frac{1}{3}[/tex] d - 2 ( multiply through by 3 to clear the fraction )
3 = d - 6 ( add 6 to both sides )
9 = d
Answer:
d=9
Step-by-step explanation:
First we can do same to both side by adding 2 to both sides:
1=1/3d-2
+2 +2
--------------
3 = 1/3d
Then to get the d on its own, we multiply each side by 3
3=1/3d
*3 *3
---------
9=d
Our final answer is 9
