carlos has a tub that can hold 2 1/4 L, which is a third of what Corey's container can hold. Corey's container is half full of w
stiv31 [10]

Answer:

3\frac{3}{8} liters

Step-by-step explanation:

We have been given that Carlos has a tub that can hold 2 1/4 L, which is a third of what Corey's container can hold.  

This means that Corey's container will have 3 times the water that Carlos's tub can hold.

Let us convert 2 1/4 into mixed fraction.

2\frac{1}{4}=\frac{9}{4}

Now we need to find 3 times of \frac{9}{4} liters as:

\frac{9}{4}\times 3=\frac{9\times 3}{4} = \frac{27}{4}

So Corey's container can hold \frac{27}{4} liters of water.

We are also told that Corey's container is half full of water. So to find amount of water, we will divide total amount of water by 2 as:

\frac{27}{4}\div 2

\frac{27}{4}\div \frac{2}{1}

Convert division problem into multiplication problem by flipping the 2nd fraction.

\frac{27}{4}\times \frac{1}{2}

\frac{27}{4\times 2}=\frac{27}{8}

\frac{27}{8}=3\frac{3}{8}

Therefore, Corey's container has 3\frac{3}{8} liters of water.

The repeating decimal, is converted to the fraction
zzz [600]

Hello!

By using a certain formula, a repeating number with two repeating digits will always become the number out of 99. In our case, we would get \frac{27}{99}.

To get the numerator to equal three, we divide both sides by 9.

\frac{27}{99} =\frac{3}{11}

Therefore, x=11.

I hope this helps!

Write a recursive rule for the sequence. Assume it starts with the 1st term. 10, 14, 18, 21...
Papessa [141]

Option D is correct. The correct option for the recursive formula is f(0) =6;f(n)=f(n - 1)+4

Given the sequence 10, 14, 18...

The first term is 10, hence

a1 = 10

The previous terms will be a_{n-1}

From the sequence, we can see that <em>4 is being added to the previous term to get the next term</em>. Hence the nth term will be expressed as:

a_n = a_{n-1} + 4

Get the term before the first term a_0

If n = 1

a_1 = a_{1-1} + 4\\a_1 = a_{0} + 4\\a_0=a_1-4\\a_0=10-4\\a_0=6

Hence the correct option for the recursive formula is f(0) =6;f(n)=f(n - 1)+4

The perimeter of the window of the camper shell is 130 in. Find the length of one of the shorter sides of the window.
erik [133]

You can't deduce the length of a side from the perimeters of a rectangle.

Say that s and S are, respectively, the short and long side of the rectangle.

So, we know that

2s+2S=130 \iff 2(s+S)=130 \iff s+S=65

But we can't solve exactly for s nor for S, unless more information is given.
