Jordan takes 50% of the cherries from a bowl. then Mei takes 50%of the remaining cherries. Finally Greg takes 50 %of the remaining cherries. There are 3 cherries left. How many cherries were in the bowl before Jordan arrived

Answers

Answer 1
Answer:

Answer:

24

Step-by-step explanation:

Let total cherries in a bowl=x

Jordan takes cherries=50% of x=(50)/(100)x

Remaining cherries=x-(50)/(100)x=(50)/(100)x=(x)/(2)

Mei takes cherries=50% of (50x)/(100)=(x)/(4)

Now, remaining cherries=(x)/(2)-(x)/(4)=(x)/(4)

Greg takes cherries=50% of(x)/(4)=(x)/(8)

Now, remaining cherries=(x)/(4)-(x)/(8)=(x)/(8)

Now,remaining cherries in a bowl=3

We have to find total cherries in a bowl before Jordan arrived.

According to question

(x)/(8)=3

x=3* 8=24

Hence,  total cherries in a  bowl=24

Answer 2
Answer: So in the final smallest bowl when half are removed there are 3 so the total amount was double 3 which is 6 before greg removed some.
Mei had removed half of the cherries which left 6 cherries so the total amount before Mei removed half was 12.
Jordan took half of the cherries which left 12. If you follow the same logic you double 12 which makes....
Good luck, hope this helped you understand the question more, feel free to comment and ask for help :)

when might you want to measure the length of an object to the nearest quarter inch as opposed to the nearest half inch

Answers

A quarter inch can also be expressed as 0.25 inch and the half inch can be expressed as 0.5 inch. We might want to measure the length of an object to the nearest quarter inch when its length is a little over a quarter inch only but not very near to 0.5 inch. 

Solve the following system of equations using elimination (addition)5x - 6y = - 32

3x + 6y = 48

Answers

Answer:

x = 2

y = 6 1/3

Step-by-step explanation:

5x - 6y = -32

3x + 6y = 48

-----------------

8x = 16

x = 2

5(2) - 6y = 48

10 - 6y = 48

-6y = 48 - 10

-6y = 38

y = 6 1/3

Which shows 232 − 172 being evaluated using the difference of perfect squares method?232 − 172 = (529 + 289)(529 − 289) = 196,320
232 − 172 = 529 − 289 = 240
232 − 172 = (23 + 17)(23 − 17) = (40)(6) = 240
232 − 172 = (23 − 17)2 = (6)2 = 36

Answers

difference of perfect squares is a² - b² = (a+b)(a-b)

Here, we can let 23 = a and 17 = b, so using this method, we have
23
² - 17² = (23+17)(23-17) = 40 × 6 = 240

So third option is correct.

Answer:

Your answer is 23^2 − 17^2 = (23 + 17)(23 − 17) = (40)(6) = 240, or C on your answer sheet.

Step-by-step explanation:

Lets begin!

So when a binomial is composed of two perfect squares separated by a subtraction symbol, a certain method called the difference of perfect squares can be used. The difference of perfect squares method can be done by multiplying the sum and difference of the two square roots.

So, to solve:

23^2 - 17^2 = (23 + 17)(23-17) = (40)(6) = 240

Thus being your answer.
