Type an equivalent expression to show the relationship of multiplication and addition<br> 7+7+7+7+7
nikitadnepr [17]
7 • 5



Multiplication is basically repeated addition. So to convert repeated addition to multiplication, we take the number being added (7) and multiply it be the number of addens (5). Therefore, 7+7+7+7+7 = 5 • 7

What is 22/9 as a mixed number
sergiy2304 [10]
If you do 22÷9 and see the hole number: 2. Then do 2 x 9 and you get 18. Now do 22-18 and you get 4. So do 2 4/9. Always have the denominator stay the same.

4. Tikili wants to invest $3500 at her local bank. She will receive an interest rate of 5% compounded
alexandr402 [8]

Answer:

3863.35 = 3500(1 +  \frac{0.05}{2} )^{(2 \times 2)}

Step-by-step explanation:

The formula for this equation is

a = p(1 +  \frac{r}{n} )^{(n \times t)}

a is the final result

p is the starting amount (deposited)

r is the interest rate

n is the number of times it's compounded

t is the time

because it says compound annually and it's after 2 years both t and n equal 2. I rounded a for you, but if you don't need it rounded here it is: 3863.345117

Please double check me I may be wrong, this is my second time doing these type of questions

Please help!!! i need to show work too!!!
Verizon [17]

Answer:

1. 7/10, 2. 25, 3. 1/4 4. 4. 3/5, 5. A

Step-by-step explanation:

1.  Make a fraction with the total number of cards at the bottom (60) and all the cards that are not green (aka yellow and blue) on top (42). Then simplify the fraction 42/60 by dividing both terms by 6 to get 7/10

2. For this one, first find how many students out of the first 80 liked basketball by subtracting the 60 students who liked other sports from 80. This gives you 20. Now you know that 20/80 students like basketball. Now simplify the fraction to get 1/4. Then find 1/4 of 100, because we know that 1/4 of students like basketball. 1/4 of 100 is 25.

3. This problem is exactly the same as number 1, except instead of adding all the other colors and putting them as a fraction over the total, just put the number of pink shirts over the total number of shirts to get 3/12. Then simplify it to 1/4, and that's your answer.

4. This is also similar to problems 1 and 3. Just put the number of heads coin tosses over the total and simplify it.

5. This one is very similar to all the problems so far. I will let you do this one on your own. Remember: The number of cases (rolls or colors or sports or cards etc.) that you want to find the probability for goes on top, and the total number of those things goes on the bottom. The bigger the fraction, the greater probability there is.

Note: Please only ask one question at a time on here instead of 5 at once. Since these problems are so similar, chances are, you could have figured them out on your own with a little help on one of them. You are more likely to get a quick answer if the answerer doesn't have to do as much work.
