- Each person stacks 20 in one minute.

- 5 people can stack 100 in 5 minutes.
If so, how long would 250 take them ?

-- The same 5 people can stack 250 in (250/100)= 2.5 minutes.

Ok, so here we need to set up a proportion.

20*5 = 100

So in a minute, the 5 people have 100 chairs stacked.

1/100 = x/250

Cross multiply

1*250 = 100x
250 = 100x
250/100 = x
x = 2.5

So it would take 5 people 2.5 minutes to stack 250 chairs. 

Final answer: 2.5 minutes

Find the length of each side of the polygon for the given perimeter
butalik [34]

Answer:

choice number 2) 10 in, 18.5 in 31.5 in

Step-by-step explanation:

we collect and evaluate the like terms.like terms means the ones that can be evaluated. like 2y and 7y are like terms. they either can be added or subtracted to get an answer . 7y-2y =5y. but you cant subtrac or add 7y  with 5 because they are not like terms.

2y +1 + 7y + 3y + 5 = 60

(2y+7y+3y)+(1+5) = 60

12y + 6 = 60

The 6 crosses the equal sign to the other side because of like terms.And becomes a minus

12y = 60 - 6

12y = 54

y = 4.5

so,

2y +1= 2 x 4.5 + 1 =10

7y = 7 x 4.5 = 31.5

3y + 5= 3 x 4.5 + 5 =18.5

Answer is 10 in, 18.5 in, 31.5 in

If you need any clarification or more explanation pls do mention at the comment section so that i can help more thx

Hope this helps and if it does pls mark as branliest answer thx

Answer:


Step-by-step explanation:

The 20th of February for seven nights:

Mr. Jones: 714

Mrs. Jones: 714

Child 1: 95% of 714 = 678.30

Child 2: 95% of 714 = 678.30

Total Price: 2784.60


The 10th of April for fourteen nights:

Mr. Jones: 802

Mrs. Jones: 802

Child 1: 85% of 802 = 681.70

Child 2: 85% of 802 = 681.70

Total Price: 2967.40


The 10th of April for fourteen nights is 182.80 pounds greater than the 20th of February for seven nights.
