Answers
P(nw) = no wins / total
no wins = 147
Total = 156
Calculation for no wins
P(nw) = 147 / 156 = 0.9423
Calculation for winners.
P(w) = 1 - 0.9423
P(w) = 0.05769
Another way.
You could calculate the winners from the total
156 - 147 = 9
P(w) = 9/156 = 0.05769 Same answer as before. Pick the method you like best.

What must you do if you multiply one number in a ratio by n?
Answers
From what I know, when you multiply one number in a ratio, you must also multiply the other number by the same number. This allows for the ratio to stay the same, thus keeping it correct. If both terms were not multiplied by n, the ratio would no longer be the correct ratio.

Answers
4 * s
where s is the side length.
Area is:
s * s
So, we can set both of these values to 196.
4s = 196
s = 49
s * s = 196

Hideki throws a baseball ball upward with an initial velocity of 12 meters/sec. When he throws the ball, it is two meters above the ground. How long will it take the ball to hit the ground?
Answers
h (t) = (1/2) * (- 9.8) * t ^ 2 + 12 * t + 2
Rewriting we have:
h (t) = -4.9 * t ^ 2 + 12 * t + 2
When the ball hits the ground we have:
-4.9 * t ^ 2 + 12 * t + 2 = 0
Solving the polynomial we have:
t1 = -0.16
t2 = 2.61
We ignore the negative root because it is time.
Answer:
It will take the ball to hit the ground about:
t = 2.61 sec
Answer:
-4.9^2 + 12t + 2 = 0

A saving account pays 3.6% per annum simple interest Heidi puts £400 into the account, how much will she have in the account after 5 years?
Answers
0.036(400)+400
Because it is 5 years:
5(0.036(400))+400
0.18(400)+400
We can make it simpler:
1.18(400)
Multiply
472
SHE WILL HAVE £472
Using the simple interest formula, Heidi will gain £72 in interest on her initial £400 deposit over 5 years at an interest rate of 3.6%. Therefore, she will have a total of £472 in her account at the end of 5 years.
Explanation:The subject of this question is simple interest calculation which is a topic in Mathematics. It's all about calculating the final amount Heidi will have in her account after 5 years, with a simple interest rate of 3.6% on her initial deposit of £400.
Given the simple interest formula, Interest = Principal × Interest rate × Time, here, the principal is £400, the interest rate is 3.6% (which is 0.036 as a decimal), and time is 5 years.
Using the formula: Interest = £400 × 0.036 × 5 = £72
So, Heidi earns £72 in interest over 5 years.
To find out how much money she will have after 5 years, we will need to add the interest to the initial deposit: Amount = Principal + Interest which gives: Amount = £400 + £72 = £472
So after 5 years, Heidi will have £472 in her account.

A hose fills a hot tub at a rate of 3.45 gallons per minute. How many hours will it take to fill a 280 -gallon hot tub?
Answers
Q = V / t
Where,
Q: flow
V: volume
t: time
Clearing the time we have:
t = V / Q
Substituting the values:
t = (280) / (3.45)
t = 81.16 minutes
In hours we have:
t = (81.16) * (1/60)
t = 1.35 hours
Answer:
it will take to fill to 280 -gallon hot tub about:
t = 1.35 hours
It will take approximately 1.35 hours to fill the 280-gallon hot tub.
We have,
A hose fills a hot tub at a rate of 3.45 gallons per minute.
This can be written as an expression:
3.45 gallons = 1 minute
Now,
Multiply 280/3.45 on both sides.
280/3.45 x 3.45 gallons = 280/3.45 minutes
280 gallons = 81.16 minutes
Now,
81.16 minutes can be converted into hours.
Divide 81.16 by 60.
So,
81.16/60 = 1.35 hours
Therefore,
It will take approximately 1.35 hours to fill the 280-gallon hot tub.

what does it mean if the quotient times the divisor does not equal the dividend? What should you do?
Answers
Final answer:
When the quotient times the divisor does not equal the dividend, it means there is a remainder. Depending on the context of the problem, you can round down, express the remainder as a fraction or decimal, or choose another appropriate method.
Explanation:
When the quotient times the divisor does not equal the dividend, it means that the division did not result in an exact whole number. This is called a remainder. For example, if you divide 15 by 4, the quotient is 3 and the remainder is 3. So, 3 times 4 does not equal 15.
If you encounter this situation, you can do a few things. You can round the quotient down to the nearest whole number, or you can express the remainder as a fraction or decimal. It depends on the context of the problem and what is required.
For example, if you are dividing cookies among friends, you may want to express the remainder as a fraction, saying each friend gets 3 and a half cookies. But if you are calculating the number of whole boxes needed, you may round down to 3 boxes.

Jeremy is making a trail mix containing raisins and peanuts. Raisins cost $1.50 per pound. Peanuts cost $2.50 per pound. Jeremy spends $10.50 to make 5 pounds of trail mix. He uses the table below to organize this information. Which equation can Jeremy use to determine the amount of raisins in the trail mix?
a.r + 1.50 = 1.5r
b. r + (5 – r) = 5
c. 1.5r + 2.5(5 – r) = 10.50
d. 1.5r + 2.5(5 – r) = 5
Answers
Answer:
Option C.
Step-by-step explanation:
Let Jeremy mixes "r" pounds of raisins to make a trail mix.
As the total weight of trial is = 5 pounds
So weight of peanuts in the trail mix will be = (5 - r )
Now cost per pound of raisins = $1.50
so cost of r pounds of raisins = $1.50(r)
Cost of the peanuts = $2.50 per pound
so cost of (5 - r) pounds peanuts = $2.50(5 - r)
Jeremy spends total amount = $10.50
So expression will be
Cost of Raisins + cost of peanuts = cost of trail.
1.5r + 2.5(5 - r) = 10.50
Option C. is the answer.
Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed? (look at the image below)
The dependent variable is distance, the equation is x = 20y, and the dragonfly will travel 360 miles.
The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.

The dependent variable is time, the equation is y = 20x, and the dragonfly will travel 480 miles.
Answers
so
y = 20x
y = distance (miles) and x = time (hours)
so if x = 24 then y = 20x = 20(24) = 480
answer
The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.
Answer:
The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.Step-by-step explanation:
According to the graph, the dependent variable is Distance in miles, because it's on the vertical axis. Additionally, the independent variable is time in hours, because it's on the horizontal axis. However, you always put time as independent, because nothing affects time.
To find the equation, we just need to find the slope, using two points (0,0) and (2,40).
[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{40-0}{2-0}=20[/tex]
Therefore, the equation is [tex]y=20x[/tex], which shows a direct proportion between variables.
Now, in 24 hours, it would travel
[tex]y=20(24)=480[/tex]
It would travel 480 miles.
Therefore, the right answer is the second choice.

Question: Kara and Steven are biking around a 1,800 kilometer path. They start biking from the same place, at the same time, and in the same direction. Kara bikes at a speed of 15 km/h and Steven bikes at a speed of 30 km/h. How long will it take before Steven and Kara will be at the same place of the path next time?
Answers
============================================================
Explanation:
The path is 1800 km. Kara's speed is 15 km/h. If this speed is held the same throughout the path, then it will take her d/r = 1800/15 = 120 hours to travel the entire path until she gets back to her starting point.
For Steven, it takes him d/r = 1800/30 = 60 hours to make the same journey.
The LCM of 60 and 120 is 120
Every 120 hours, both Kara and Steven will be back at the starting point together.
Note: this is a very very large time value, and this is not considering the fact that the bikers slow down or stop to take a break.
