PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer:  $25,500

<u>Step-by-step explanation:</u>

The given sequence {1300, 1300+150, ... } provides the following information:

  • the first term (a₁) = 1300
  • the difference (d) = 150

We can use the information above to find the explicit rule of the sequence:

a_n=a_1+d(n-1)\\.\quad =1300+150(n-1)\\.\quad =1300+150n-150\\.\quad =1150+150n

We can use the explicit rule to find the 12th term (a₁₂)

a_n=1150+150n\\a_{12}=1150+150(12)\\.\quad =1150+1800\\.\quad =2950

Next, we can input the first and last term of the sequence into the Sum formula:

S_n=\dfrac{a_1+a_n}{2}\times n\\\\S_{12}=\dfrac{a_1+a_{12}}{2}\times 12\\\\.\quad =\dfrac{1300+2950}{2}\times 12\\\\.\quad =\dfrac{4250}{2}\times 12\\\\.\quad =2125\times 12\\\\.\quad =25,500

Mika needs to equally separate 12.25 ounces of puppy food in order to feed 8 puppies the same amount. How many ounces of food wi
Reil [10]

Equation: 8p = 12.25

Ounces of food per puppy: Approximately 1.5


Mika has 12.25 ounces of puppy food to feed 8 puppies.

All 8 puppies need the same amount.

So, how many ounces of food will each puppy get?

That's where I come in.

I guess.


To find out how many ounces of food each puppy gets, you must make an equation.

Luckily for you, I've already made an equation of this in my head before I even finished typing this sentence.

You can use my equation if you want.

Equation: 8p = 12.25

Divide both sides by 8 to get approximately (hence I rounded to the nearest tenth) 1.5 ounces of food per puppy.

Now you've got some nice work to show your teacher and you've got the correct answer. Well done.

He made a queen-sized quilt that was 8 feet long. its area was 64 feet. what is its perimeter
SOVA2 [1]
Depends on the shape we are talking here. I believe you are taking about a square, so:
The equation for area for a square is: s^2, s representing the length of 1 of the squares sides (a square is even all the way around, so 1 side is the same as all)
8^2=64, so I can assume this is a square by this. Knowing it's a square, and that one of the sides is equal to 8, and the other 3 sides are the same length, I can do 8*4, which equals 24.
The perimeter is 24
