ASAP!! 20POINTS!! Students just finished taking test and these are the scores: 75, 80, 62, 98, 90, 86, 55, 86, 92, 66. What is the median of the scores?
A.83
B.86
C.79
D.43
A is the answer
Step-by-step explanation:
The measure of A is 14 degrees greater than the measure of B. The two angles are complementary. Find the measure of each angle
Answer:
[tex]A = 52[/tex], [tex]B = 38[/tex]
Step-by-step explanation:
The sum of two complementary angles is always [tex]90[/tex]°
[tex]A + B = 90[/tex]
[tex]A = B + 14[/tex]
substitute [tex]A[/tex] for [tex]B = 14[/tex]
[tex](B + 14)+ B = 90[/tex]
[tex]2B + 14 = 90[/tex]
[tex]2B = 76[/tex]
[tex]B = 38[/tex]
input this into the original equation
[tex]A + 38 = 90[/tex]
[tex]A = 52[/tex]

Given the equation find the y-intercept. Write it as a coordinate ( 0 , y ).
y=-4x+3
Answer:
(0, 3)
Step-by-step explanation:
The equation already shows the y-intercept (written as +3). The slope is -4x and the y-intercept is (0, 3).
Answer:
y=3
Step-by-step explanation:
Because we know x equals 0 we put that into the equation so then you have y=4(0)+3 you multiply 4 time 0 and get 0 so all you have left is 3.
3. Given the statement "x - 4 is a factor of f(x)= 5x* – 22x - 2x2 – 25x +4". explain how to verify the
statement is accurate.
Step-by-step explanation:
x - 4 = 0
=> x = 4
f(x)= 5x – 22x - 2x² – 25x +4
By remainder theorem,
f(4)= 5(4) – 22(4) - 2(4)² – 25(4) + 4
= 20 - 88 - 32 - 100 + 4 ≠ 0
Since the remainder is not 0, x - 4 is not a factor.
Hope it helps :)

Every three years the population of one part of Brooklyn is recorded.
In 2014 there was a population of 10,500 people.
From 2014 to 2017 the population increased by 22%.
From 2017 to 2020 the population decreased by 10%.
What was the population of this area in 2020?
Answer:
11,529
Step-by-step explanation:
10500x22%=2310
10500+2310=12810
12810x10%=1281
12810-1281=11529
Answer:
Hello there!
Your question asks to find what was the size of the population in 2017
Answer: 6,721
In order to solve this problem, we're going to need to use the given information in the question in order to find the population in 2017.
Key information:
In 2010, population was 6500
In 2014, population increased by 10% from 2010
In 2017, population decreased by 6% from 2014.
With the information above, we can solve the problem.
We're going to start with 6500 as our starting population.
We know that the population increased by 10% in 2014, so we would multiply 6500 by 1.10.

maths help please!!!!!!!!!!!
Answer:
Step-by-step explanation:
Remark
Assume all of the sheet of plywood is to be used.
Front and back = 2 * 2x *h
Top and Bottom = 2 * 2x * x
Left/Right side = 2 * x * h
Total area = 4xh + 4x^2 + 2xh
Total area = 6xh + 4x^2
Total area = 600
6xh + 4x^2 = 600
h = (600 - 4x^2)/6x
h = 100/x - 2/3 x
Volume = x * 2x * h
Volume = 2x^2 * (100/x - 2/3 x)
Volume = 200x - 4/3 x^3
I can do this without calculus (I think), but it is much easier to use it.
dV/dx = 200 - 4x^2
This is a maximum when dV/dx = 0
dV/dx = 200 - 4x^2 = 0
4x^2 = 200
x^2 = 50
x = 5√2

Karla is selling tickets for a high school play. Child tickets cost $7 and adult tickets cost $13 she sells 180 tickets and collects $1830 Setup a system of equations using C for number of child tickets and A for number of adult tickets to find the number of each ticket sold
Answer: The number of child tickets is 85 and the number of adult tickets is 95.
Step-by-step explanation:
Let C = Number of child tickets
A = Number of adult tickets.
As per given, we have
C+A=180 (i)
7C+13A=1830 (ii)
Multiply 7 to both sides of equation (ii), we get
7C+7A=1260 (iii)
Eliminate (iii) from (ii) , we get
[tex]6A=570\\\\\Rightarrow\ A=95[/tex]
Put value of y in (i), we get
C= 85
Hence, the number of child tickets is 85 and the number of adult tickets is 95.
What is 45 minutes before 7 o'clock
Answer: Its 6:15
Step-by-step explanation:
Its simple math. 7:00 subtract 45minutes, knowing that 60minutes is an hour and that its the 7 hour from the 6 hour. Gets you 6:15.
Yep.
The 45 minutes before 7 o'clock will be 6.15 AM/PM.
What is the time?the indefinite continued progress of existence and events in the past, present, and future regarded as a whole.
In other words, time is something which measure by motion and it is given by einstein that time depends upon motion.
For example time = distance/velocity so it means time also depends on velocity.
In the given question, we know that in
1 hour = 60 minutes
45 minutes before of 7 o'clock = 60 - 45 = 15 minutes after 6 o'clock hence 6.15 minutes will be correct answer.

LAST question !! need help with number 9 but if u can help me with #8 ur an angel
Answer:
8) interior angle = 160
9) x = 20
Step-by-step explanation:
8)
18-gon has 18 sides
The formula for sum of interior angles for an 18-gon is:
(18x180)-360 = 2880 degrees
2880 degrees / 18 angles = 160 degrees
9)
exterior angles = 360 degrees
360 = (3x-2)+(x+8)+(4x+9)+(2x-1)+(3x)+(4x+6)
360 = 3x-2+x+8+4x+9+2x-1+3x+4x+6
360 = 17x+20
17x = 340
x = 20 degrees
