Answer:
Carter family = 25 hours
Davis family = 31 hours
Step-by-step explanation:
Let's say the number of hours the Carter family used their sprinkler is x and the number of hours the Davis family used their sprinkler for is y.
So combined:
x + y = 45 hours
and we are also told that:
40x + 15y = 1300 L
So we can do simultaneous equations to solve the problem.
With some rearranging, we can figure out that:
y= 45 - x
and by substituting that into the second equation:
40x + 15 (45 -x) = 40x + 675 - 15x = 1300L
25x = 1300 - 675
25x = 625
x = 25 = hours that the Carter family used their sprinkler
and we can substitute that back into the original equation to find how many hours the Davis family used their sprinkler so:
25 + y = 56
y = 31
The Davis family used their sprinkler for 31 hours whilst the Carter family used their sprinkler for 25 hours.

we know that
if m ∠DAB=23.5°
then
arc DB=23.5°------> by central angle
the answer isarc DB=23.5°
Answer:7350
The total arrangements of the letters in Mississippi having no consecutive s's=70X105=7350. So, the answer is 7350.Hence, the distinct permutations of the letters of the word MISSISSIPPI when four I's do not come together = 34650 – 840 = 33810.

<u>Step-by-step explanation:</u>
Here we have , Wyatt makes and sells rope doormats. He uses 200 feet of rope for each doormat. He wants to make 25 doormats. We need to find Which expression shows a correct way to find how many yards of rope he needs. Let's find out:
Wyatt makes and sells rope doormats. He uses 200 feet of rope for each doormat , i.e. for 1 doormat he uses 200 feet of rope
⇒ 
So , for 25 Doormat he uses :
⇒ 
⇒ 
But , 
⇒ 
.Hence ,
⇒ 
Hence Correct answer is or , 200×25÷3 . Given answer is not in any of option! kindly match this answer with your options available!
