Put this into ratio form:
20 baskets/ 4 minutes.
This means for every 4 minutes, you can make 20 baskets.
Now solve for 1 minute...how many baskets can you make in one minute.
You can solve this in many ways:
1. Cross Multiply:
20/4 = x/1...20×1= 20 ÷ 4= 5 baskets per minute
2. Simplify- (simpler way to solve)
20 baskets ÷ 4 minutes= 5 baskets in 1 minute
3. Critical Thinking:
how many times can 4 go into 20? 5 times. So there are:
5 baskets per minute
First, we add everything together, so; 3 + 3 + 4 + 2 = 12. This means every marble has a 8.33% chance of being chosen, however since there are more than others we add those separate percentages together.
Pink: 25%
Violet: 25%
Yellow: 33.33%
Brown: 16.66%
These are the chances of you getting either color. Since the problem asks what is the probability of finding a violet marble,we just look at the written percentages to see we have a 25% chance of choosing a violet marble.
The next step is to see what is the probability of choosing a pink marble, except we have to change things up a bit. Since we removed 1 marble, that changes ALL the percentages again, so we must rewrite the percentages. 12 - 1 is easily solved as 11, and so this means every marble has a 9.0909091% of being chosen. Let's rewrite the grouped percentages now:
Pink: 27.27%
Violet: 18.18%
Yellow: 36.36%
Brown: 18.18%
Now we see that with one marble removed, and that marble not being pink, we have a 27.27% chance of picking a pink marble.
Your Answer: 25% of Violet first time, 27.27% of Pink second time.
(How To Get Percentages?): Simple, you divide 100 (since whatever number we start out with as long as it claims nothing is missing equal 100%) by whatever number of objects you have. So as an example, if I have 5 objects, 100 / 5 = 20. This means every individual object has a 20% chance of being chosen. But we then arrange everything into whatever groups (in your problems case, colors) and multiply by the amount. So say I have 3 green balls and 2 white balls, 3 x 20 = 60 and 2 x 20 = 40 so I have a 60% of getting a green ball and 40% chance of a white ball.

<u>The total average credit card debt for a U.S household will be </u><u>$9292.</u>
<h3>
How much is considered a lot of credit card debt?</h3>
- If your total balance is more than 30% of the total credit limit, you may be in too much debt.
- Some experts consider it best to keep credit utilization between 1% and 10%, while anything between 11% and 30% is typically considered good.
We are given that an expression which gives an approximate value of the total average credit card debt in a U.S. household (in dollars )t years after 1995
We have to find the total average credit card debt will be in the year 2004.
Number of years =2004-1995=9
t=9 years
Substitute the value of t in the given expression
Then , total average credit card debt in a U.S household will be in the year
Debt(t)=418t+5530
Debt(9)=418 * 9+5530= $9292 in 2004
Hence, in the year 2004, the total average credit card debt for a U.S household will be $9292.

Well the formula for the volume of a rectangular prism is v=whl or volume= width times height timed length, so let's apply what we know to that. Volume=5*4*4 basically is the math equation we are solving, however because the width and length make up the base we must do the length and width first because another version of the formula is B*h which is area of base *height and width *length equals the area of the base so 4*4= 16, 16*5=80 your answer is the third one 80km^3
Answer:
A polyhedron with 6 faces and 8 vertices has 12 edges.
Step-by-step explanation:
Euler Formula is given in the problem:
We are told that the polyhedron has 6 faces (F = 6) and 8 vertices (V = 8). The only unknown variable in Euler's Formula now is E = number of edges.
Substitute the known variables into the formula and <u>solve for E</u>.
- 6 + 8 = E + 2
- 14 = E + 2
- 12 = E
- E = 12
A polyhedron with 6 faces and 8 vertices has 12 edges.
