You and your mom enter a drawing with 3 different prizes. A total of 9 people entered the drawing, and prizes are awarded randomly. There are 504 ways to reward the prizes. What is the probability that you win first prize and tour mom wins second prize?
Answer:
[tex]\frac{1}{72}[/tex]
Step-by-step explanation:
We have been given that there are total 9 people who entered the drawing competition. There are 3 prizes to be distributed to the winners. The total number of ways that 3 prizes can be awarded to the 9 people can be determined as 9*8*7 = 504.
The total number of ways in which I win the first prize and my mom wins the second prize would be 1*1*7 = 7.
Therefore, the probability that I win the first prize and my mom wins the second prize would be: [tex]\frac{7}{504}=\frac{1}{72}[/tex]

In trapezoid ABCD with bases AB and DC , diagonals intersect at point O. Find the length of diagonal BD , if BO=6 cm and: AO/OC = 3/1
Answer:
BD = 8 cm
Step-by-step explanation:
Diagonals of trapezoid divides each other in equal ratio.
if ABCD is a trapezoid and the diagonals AC and BD intersect at point O
then we have
[tex]\frac{AO}{OC} =\frac{OB}{OD}[/tex]
it is given that
[tex]\frac{AO}{OC} =\frac{3}{1}[/tex] and BO=6 cm
so we can write
[tex]\frac{3}{1} =\frac{6}{OD}[/tex]
cross multiply
[tex]3 OD=6[/tex]
divide both side by 3
OD= 2 cm
now we have
BD = BO +OC
BD = 6 cm + 2 cm
BD= 8 cm
Step-by-step explanation:
The ratios of the sides is the same.
3OD=OB
Let y be the length of OD
Therefore,
3y=6
y=2,
meaning OD is 2.
OB+OD=DB

Lamar wants to determine the movie preferences
Answer:
male comedy: 31 male drama: 9
female comedy: 36 female drama: 24
Step-by-step explanation:
add f+m=100 total
31 males for comedy
40 males - 31 males = 9 males for drama
55% chose comedy so 55-31 males = 24 females for comedy
60 total females - 24 for comedy = 36 females for drama
Answer:
Dramas Comedies
Males 9 31
Females 36 24
Step-by-step explanation:
It is given that Lamar surveyed 40 males and 60 females about whether they prefer dramas or comedies.
Total males = 40
Total females = 60
Total people surveyed = 40 + 60 = 100
It is given that 55% of surveyed people preferred comedies.
People preferred comedies = [tex]100\times \frac{55}{100}=55[/tex]
It is given that males who preferred comedies = 31
Males who preferred drama is the difference of number of males and males who preferred comedies.
Males, drama = 40 - 31 = 9
Females who preferred comedies is the difference of people who preferred comedies and males who preferred comedies.
Females, comedies = 55 - 31 = 24
Females who preferred drama is the difference of number of females and females who preferred comedies.
Females, drama = 60 - 24 = 36
Therefore the table can be filled as
Dramas Comedies
Males 9 31
Females 36 24
Divide. 1/3 ÷ 4/5 Express your answer in simplest form.
To calculate 1/3 ÷ 4/5, switch the division operation to multiplication by flipping the second fraction. This gives us 1/3 * 5/4, which simplifies to 5/12.
Explanation:In mathematics, when we're asked to divide fractions, we often use the method of multiplying by the reciprocal of the second fraction.
In this case, the question asks you to perform the division operation of 1/3 ÷ 4/5.
To do this, you would first flip (or find the reciprocal) of the second fraction, which results in 5/4 instead of 4/5. Next, we perform the operation of 1/3 multiplied by 5/4 rather than division. Multiplication of these fractions gives us 5/12. Thus, 1/3 ÷ 4/5 = 5/12 is your answer in simplest form.Learn more about Divide Fractions here:https://brainly.com/question/18511795

solve for m 1/3=12-m
Answer:
m = 35/3 or 11 2/3
Step-by-step explanation:
1/3=12-m
Subtract 12 from each side
1/3 - 12 = -m
Get a common denominator
1/3 - 12*3/3 = -m
1/3 - 36/3 = -m
-35/3 = -m
Multiply by -1
-1* -35/3 = -1 *-m
35/3 = m
Changing to a mixed number

is y=5/3x+3,20x+12y=12 a parallel, perpendicular.or a neither pair equation
Answer:
Neither
Step-by-step explanation:
y = 5/3 x + 3, this line has slope = 5/3
20x + 12y = 12
12y = -20x + 12
y = -20/12 x + 1
y = - 5/3 x + 1, this line has slope = - 5/3
Parralel ; same slopes
Perpendicular; slopes are opposite and reciprocal
So answer is neither pair parallel nor perpendicular
The pair of equations y = 5/3x + 3 and 20x + 12y = 12 are parallel because they both have the same slope of 5/3 once the second equation is put into slope-intercept form.
To determine if the pair of equations y = 5/3x + 3 and 20x + 12y = 12 are parallel, perpendicular, or neither, we must first put both equations into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. The equation y = 5/3x + 3 is already in slope-intercept form with a slope of 5/3. To convert the second equation into slope-intercept form, we can rewrite it as 12y = -20x + 12, and then y = (-20/12)x + 1, which simplifies to y = -5/3x + 1.
Now, comparing the slopes of these two lines, we see that both slopes are equal, meaning the lines are parallel to each other since they have the same slope but different y-intercepts.

In a previous question we have found 2 things.
1. That we are working with a right angle triangle2. That two of the sides are both 9. We did not require the third side. Now we do.If two of the sides are 9 then in this case only we can use the Pythagorean theorem to find the third side. That is because the the base and height meet at right angles.
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
81 + 81 = c^2
c^2 = 162
sqrt(c^2) =sqrt(162)
c = 12.71
Perimeter
The perimeter = 9 + 9 + 12.71 = 30.7

If you were going to use the quadratic formula to solve the following equation and b=15, what number would you use as the value for the variable ‘a’?
-15x+22=12x^2
Answer:
You would use a = 12
Step-by-step explanation:
The b value is the coefficient that is in front of the x term, that does not have an exponent of 2. It's simply the x term (not the x^2 term)
We're told that b = 15 is used, but we see that -15 is in front of the x term. To fix this contradiction, add 15x to both sides so that you move the x term to the right side
-15x+22 = 12x^2
-15x+22+15x = 12x^2+15x
22 = 12x^2+15x
Now subtract 22 from both sides to move that term over as well
22-22 = 12x^2 + 15x - 22
0 = 12x^2 + 15x - 22
12x^2 + 15x - 22 = 0
12x^2 + 15x + (-22) = 0
The last equation is in the form ax^2 + bx + c = 0 with
a = 12, b = 15, c = -22

The area of a rectangular classroom is 420 square feet. If the length and width of the classroom are multiplied by 3, what will be the area of the new classroom?
A:1640 ft B:1720 ft C:2840 ft D:3780 ft
Answer:
D: 3780 square feet
Step-by-step explanation:
Let the length be L. Let the width be W.
The area of a rectangle is length times width, so
A = LW
The area is 420 square feet, so
LW = 420
Now you multiply the length by 3 and multiply the width by 3.
The length is now 3L, and the width is now 3W.
The area of the new rectangle is the new length times the new width.
new area = 3L * 3W
new area = 3 * 3 * LW
new area = 9 * LW
LW was the original area, and it is 420 square feet, so the new area is 9 times the old area.
new area = 9 * 420 square feet
new area = 3780 square feet

Travis can afford a $260-per-month car payment, and he is interested in either a compact car, which costs $10800, or a coupe, which costs 11,300. If he is being offered a 4-year car loan with and APR of 6%, compounded monthly, which car can Travis afford?
Answer: travis can afford the compact car but not the coupe
Step-by-step explanation:
Answer:
Travis can afford the compact car.
Step-by-step explanation:
The EMI formula is :
[tex]\frac{p*r*(1+r)^{n} }{(1+r)^{n}-1 }[/tex]
In first case:
p = 10800
r = 6/12/100=0.005
n = 4*12 = 48
Putting values in the formula we get:
[tex]\frac{10800*0.005*(1+0.005)^{48} }{(1+0.005)^{48}-1 }[/tex]
= $254
We can see that Travis can afford the compact car because the EMI is less than $260.
In second case:
p = 11300
r = 6/12/100=0.005
n = 4*12 = 48
Putting values in the formula we get:
[tex]\frac{11300*0.005*(1+0.005)^{48} }{(1+0.005)^{48}-1 }[/tex]
= $265.75
We can see that the coupe will have an EMI of $265.75 which is higher than the amount that Travis can afford.
Hence, Travis can afford a compact car.

Hari's weekly allowance varies depending on the number of chores he does. He received $20 in allowance the week he did 22 chores, and $12 in allowance the week he did 6 chores. Write an equation for his allowance in slope-intercept form.Hari's weekly allowance varies depending on the number of chores he does. He received $20 in allowance the week he did 22 chores, and $12 in allowance the week he did 6 chores. Write an equation for his allowance in slope-intercept form.
The slope-intercept form of the equation, which represents how much allowance Hari receives based on the number of chores he does, is y = 0.5x + 9. Here, the slope of 0.5 represents the amount Hari earns per chore, and 9 is the base amount Hari receives irrespective of the chores.
Explanation:The given scenario provides us with two points (22, $20) and (6, $12) where the number of chores is the x-coordinate and the allowance is the y-coordinate. We can use these points to find the slope of the line:
Slope (m) = (y2 - y1) / (x2 - x1)= ($20 - $12) / (22 - 6) = $8 / 16 = $0.5,
Next, we use the slope and one of the points to find the y-intercept: y = mx + b so $20 = ($0.5 * 22) + b, solving for b gives us b = $20 - $11 = $9, which is our y-intercept.
So, the equation of the line in slope-intercept form is y = 0.5x + 9
This equation states that Hari earns $0.5 per chore and gets a guaranteed $9 even if he does no chores.

To simplify the expression, find the common denominator, distribute the 'a' to each term, and combine like terms.
Explanation:To simplify the expression a/5x-10 + a/6x-12, we need to find a common denominator for the two terms. The common denominator is 30x(x-2). We then multiply each term by the appropriate factor to get a common denominator. This simplifies the expression to:
a(6x-12) + a(5x-10) / 30x(x-2)
Now, we can distribute the 'a' to each term:
6ax - 12a + 5ax - 10a / 30x(x-2)
Combining like terms, we get a(11x - 22) / 30x(x-2).
