Answer: 3n+2 hours
To get this answer, you divide the distance over speed
This is because
distance = rate*time
time = distance/rate
So we have
time = (distance)/(rate)
time = (6n^2+4n)/(2n)
time = (6n^2)/(2n) + (4n)/(2n)
time = 3n + 2 hours
Solve A = 1/2bh for h
Answer:
2A /b = h
Step-by-step explanation:
A = 1/2 bh
Multiply each side by 2
2A = 2*1/2 bh
2A = bh
Divide each side by b
2A/b = bh/b
2A /b = h

Answer the questions below .
Answer:
m=9n
Step-by-step explanation:
Linear equation, straight forward m=3n. Highlighted point is n=3 and m=9*3=27
The equation for the total money raised will be m = 9n.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that the drama club sells sweatshirts for $9 dollars each to raise money for their club.
From the table:-
The number of Sweatshirts Money raised
1 9
3 27
4 36
The equation will be written as:-
m = 9n
m = 9 x 1 = 9
m = 9 x 3 = 27
m = 9 x 4 = 36
Therefore, the equation for the total money raised will be m = 9n.

Andrew believes the honor roll students at his school have an unfair advantage in being assigned to the math class they request. He asked 500 students at his school the following questions: "Are you on the honor roll?" and "Did you get the math class you requested?” The results are shown in the table below:
(attached)
Help Andrew determine if all students at his school have an equal opportunity to get the math class they requested. Show your work and explain your process for determining the fairness of the class assignment process.
Answer:
Honor students have a probability of 43% to non-honor students 25%.
Step-by-step explanation:
Prob of honor student getting math class choice = 215/500 = 43%
Prob of non-honor student getting math class choice = 125/500 = 25%

x²+x=0
x³-25x=0
x²=4x
4x²-4x=1
Answer:
x²+ x = 0
x ( x +1 ) = 0
x = -1
x³-25x=0
x ( x² - 25 ) = 0
x² = 25
x = 5
x²=4x
x² - 4x = 0
x ( x- 4 ) = 0
x = 4
4x²-4x=1
4x²-4x - 1 = 0
4 x² - 2x - 2x - 1 = 0
2x ( 2x - 1 ) - 1 ( 2x- 1 ) = 0

Answer:
1. 792 2. 20. 3. 126. 4.1995840
Step-by-step explanation:
Use the formula C(n,r)= n!/ r/ (n-r)! where n is total quantity of varieties and r is the quantity uou should choose.
1) n=12 (total quantity); r= 7
C(12,7)= 12!/(7! *(12-7)!)= 8*9*10*11*12/ (5*4*3*2)= 8*9*11= 72*11= 792
2) n=6 r=3
C(6,3)= 6!/ (3! * (6-3)!)= 6!/ (3!)^2= 4*5*6/ 3*2= 20.
3) C(9,5)= 9!/ (5!*4!)= 6*7*8*9/ (4*3*2*1)= 2*63= 126
4) You need to choose the whole set which consists of three components that has been defined. Multiply previous results
792*20*126= 1995840.

A. 10
B. 7.5
C. 7
D. 6.8
Answer:
7
Step-by-step explanation:
the median is the middle value of the list. first off, write the list of numbers in ascending order (small to big)
3, 4, 4, 5, 7, 7, 8, 10, 10, 10
since there are 10 values, there are two middle numbers which are 7 and 7. since they are both 7, the median is 7
3. If bº = 110°, what is the value of gº?
Answer:
hello mate <3
u see here its a quadrialteral
with 4 angles b , d , 70 , g
so b + d + 70 + g = 360
now u see 60 + d = 180 (straight line)
d = 120 and b = 110 ( given)
so
110 + 120 + 70 + g = 360
g + 300 = 360
g = 360 - 300 = 60 degrees option c

If f(x) = -2[x] + 8, what is f(-1.8)?
O 4
O 6
O 10
O 12
Answer:
12
Step-by-step explanation:
since the function is -2x+8 and you have been told to find f(-1.8) you have to replace -1.8 were there's x in the function.
f(x)=-2x+8
f(-1.8)=-2x+8
=-2(-1.8)+8
=3.6+8
=11.6 round off to 12
