In order to add the fractions 2/5 + 3/4, first, we need to find the least common denominator. The LCD for 4 & 5 is 20. Now that we know the LCD is 20, what are the new equivalent fractions?

Answers

Answer 1

Answer:

8/20 and 15/20 and then you add to get 23/20 AKA 1 3/20

Step-by-step explanation:

Since you multiply 5 by 4 to get the LCD, apply the same method to the top: 2 times 4 is 8

Next do the same for the other fraction: 4 times 5 is 20 so apply that to get 3 times 5 is 15

Your final fractions will be 8/20 and 15/20

Then add and reduce to get 1 3/20

Step-by-step explanation:

2: 56 times 3.14 = 175.84 --> Nearest tenth: 176.8

4: I can't see the problem, sorry :(

Answer:

2. 2461.8

4. 86.6

Explanation:

your formula for area is pi×radius^2

you are using 3.14 for pi

and your radius is half way across the circle or half the diameter.

2. 3.14×(28)^2

3.14×784

=2461.8

4.This one shows the diameter so you have to divide it by 2 first.

10.5/2=5.25

radius=5.25

3.14×(5.25)^2

3.14x27.5625

=86.6

Comcast Corporation is the largest cable television company, the second largest Internet service provider, and the fourth largest telephone service provider in the United States. Generally known for quality and reliable service, the company periodically experiences unexpected service interruptions. On January 14, 2009, such an interruption occurred for the Comcast customers living in southwest Florida. When customers called the Comcast office, a recorded message told them that the company was aware of the service outage and that it was anticipated that service would be restored in two hours. Assume that two hours is the mean time to do the repair and that the repair time has an exponential probability distribution.

L (1+0.2)C. 0.8L Read the passage and answer the question that follows:Despite our best efforts as parents, we will always make mistakes in raising our children. It's inevitable. There are so many decisions to be made in any given day, week, month, or year. It's an inhuman task to make all ofthese decisions correctly. Who would even want to try for perfection?We shouldn't worry too much, though, because it is precisely our mistakes that teach our children the most about life. Life is full of mistakes, obstacles, and trouble. Shielding our children from these by striving for perfection inour own parenting does them no favors.Given this, a parent might be tempted to give up trying to make good decisions and simply bet the chips fall where they may. Admittedly, that attitude is not without its benefits, but it goes too far in the other direction. Childrenare much more observant than we think, but often draw the wrong conclusions from what they observe. If we give up trying to make the right decisions, they might get the message that we don't care about their future.We can take comfort in this much: we teach our children even when we're not trying to. That doesn't mean we should stop trying to do our best to make the right decisions whenever possible. It just means that we shouldn'tbest ourselves up when we make mistakes. Either it won't matter because it's something small, or it just might build some character in our children, a commodity that will serve them well.Which of these sentences from the passage most directly expresses the counterclaim?

On August 1, Sparky assigned $100,000 of the accounts receivable to B Bank and received 90% of the value of the accounts assigned less a finance fee of $1,000. B Bank charges 1% per month on the outstanding loan balance. Cash collections from assigned accounts are to be remitted monthly to B Bank to cover both principal and interest payments. During August Sparky collected $30,000 in cash of the accounts receivable assigned and also accepted sales returns of $3,000 from assigned accounts. During September, Sparky collected $50,000 in cash on accounts assigned and, in addition, wrote off $2,000 of assigned accounts receivable as uncollectible.
