Five horses are running at a race track. Being an inexperienced bettor, you assume that every order of finish is equally likely. You bet that Son-of-a-Gun will win and that Gentle Lady will come in second. What is the probability that you will win both bets?
Answer:
The probability that you will win both bets is 0.05.
Step-by-step explanation:
There are five horses running at a race track.
The total number of ways in which the race can finish is: 5! = 120.
Now the bet placed is:
Son-of-a-Gun will win and that Gentle Lady will come in second.
So, the first two places are fixed.
The remaining three can be arranged in 3! = 6 ways.
That is there are 6 ways in which the bet can be won.
Compute the probability of winning the bet as follows:
[tex]P(Win)=\frac{6}{120}=0.05[/tex]
Thus, the probability that you will win both bets is 0.05.

A car that has a weight W is on an inclined plane with an angle of pi/12. A cable is holding the car in place ( the whole problem is shown the picture )
Answer:
Ok, in this problem we first need to define the components parallel and perpendicular to the plane of the inclined plane, so we can project the gravitational component in each one of these. (see the image below to see the change in coordinates)
The perpendicular component will be defined by -cos(pi/12) (because the weight vector points down) and the parallel one is defined by sin(pi/12).
Now, the gravitational force will be, in magnitude, F = g*w
where g is the gravitational acceleration: g = 9.8m/s^2
Now, the perpendicular projection is:
Pe = -W*9.8m/s^2*cos(3.14/12) = W*9.799 m/s^2 (this component is canceled due to the normal force of the inclined plane)
The parallel projection will be:
Pa = W*9.8m/s^2*sin(3.14/12) = W*0.045 m/s^2
Now, we know that the car is still, then the tension on the cable must be equal in magnitude to this force (but in the opposite direction)
Then the module of the tension of the cable is:
ITI = W*0.045 m/s^2
or
T = -W*0.045 m/s^2 in the parallel axis.
b) The force that the pavement is applying on the car will be the normal force, that is equal to the perpendicular projection of the gravitational force (But again, in opposite direction).
Then the magnitude will be:
INI = W*9.799 m/s^2

X -6= 11 - 11(x + 7)
HELPPP PLSSS
Answer:
x = -5
Step-by-step explanation:
X -6= 11 - 11(x + 7)
Distribute
x-6 = 11 -11x -77
Combine like terms
x-6 = -11x -66
Add 11x to each side
x-6+11x = -11x-66+11x
12x-6 = -66
Add 6 to each side
12x -6+6 = -66+6
12x = -60
Divide by 12
12x/12 = -60/12
x = -5
Janae vacuums her house every 2 days, she mops every 4 days and does laundry every 6th day. On what day of the month will she have to do all 3 chores on the same day?
On 24 of the month, she has to do all 3 chores on the same day.
Given that,
Janae vacuums her house every 2 days, mops every 4 days, and does laundry every 6th day. On what day of the month will she have to do all 3 chores on the same day is to be determined.
In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.
Here
The combination can be given as
Date for vacuums for every 2 days = {2, 4, 6, 8, ....., 30} = every even nunber,
Dates for mopes every 4 days = {4, 8, 12, 16, 20, 24, 28}
Dates for laundry every 6 days = {6, 12, 18, 24, 30}
The common number in each of the three sets is 24.
Thus, On the 24 of the month, she has to do all 3 chores on the same day.

Determine whether any of the ratios below are proportional. 10/45, 20/90 and 6/27
Answer:
Yes, all three of them are proportional
Step-by-step explanation:
First, let's simplify them all the way:
10/45 = 2/9
20/90 = 2/9
6/27 = 2/9
All three of these ratios simplified down to their simplest form are 2/9, meaning that they are all proportional.

Write a problem that requires multiplying two decimals to find the answer. The product must have two decimals places.
Answer:
3.5 * 6.7 = 23.45
Step-by-step explanation:
(I am assuming you know how to do 2-digit by 2-digit problem, but just in case you don't I am putting in how to do it.)
You would multiply the problem like a normal 2-digit by 2-digit problem.
- multiply the ones places (5*7=35)
- you bring the 3 of the 35 and put it above the other 3
- you then do 7*3=21+3 because you moved it.
-so the first part of the question would be 35*7=245
-you go below the 5 and put a zero because you dont need the ones place anymore.
-you then do the same thing but with the tens place instead.
- You would then get 35*6=210, but you can't forget the zero.
- you would then add 245+2100=2,345
- But don't forget the decimals. you have to add the decimals to the answer.
- you count how many numbers that are behing both numbers, in this case it would be two.
- you then put the decimal after the ones and tens place.

A problem that requires multiplying two decimals is "If length of a rectangle is 0.2 m and breadth of a rectangle is 0.5 m. Then what is the area of the rectangle?"
What is Multiplication?Multiplication is an operation that embodies the fundamental concept of continuously adding the same integer. Factors are the numbers that have been multiplied, and the outcome of multiplying two or more numbers is known as a product of those numbers. It is made easier to add the same number repeatedly by multiplying it.
It is difficult and error-prone to manually multiply values to more than a few decimal places. Since adding logarithms results in multiplication, common logarithms were created to make such calculations simpler. The number could be easily multiplied to an accuracy of roughly three thanks to the slide rule.
Here we are taking two decimal numbers 0.3 and 0.4.
If length of a rectangle is 0.4 m and breadth of a rectangle is 0.3 m.
Then what is the area of the rectangle ?
So, Area of a rectangle = Length × Breadth
= 0.4 x 0.3
= 0.12
Thus, 0.12 is a two decimal number.

every 4.5 years. What is the value of the car 21 years after it was purchased, to the
nearest hundred dollars?
Answer: it’s 1900
Step-by-step explanation:
The value of the car 21 years after it was purchased, to then earest hundred dollars is $1900.
What is the value of the car in 21 years?
When an asset depreciates, it means that it declines in value with the passage of time.
The formula for calculating future value:
FV = P (1 +-r)^n
FV = Future value P = Present value R = rate of decline = 50%N = number of years : 21 / 4.5 = 4.6749,000(0.5^4.67) = $1900
