Answer: 38 feet.

Step-by-step explanation:

The beds have the same dimensions.

Then, to find the number of feet of fabric that Carrie will need to make skirts for both beds, you need to calculate the perimeter of one of them and multiply it by 2. After this, you can make the conversion from inches to feet.

The perimeter of a rectangle can be calculated with this formula:

P=2l+2w

Where "l" is the length and "w" is the width.

You know that the dimensions of each bed are:

l=75in\\w=39in

Then you can substitute these values into the formula:

P=2(75in)+2(39in)\\P=228in

Therefore,  the number of inches of fabric that Carrie will need to make skirts for both beds is:

P_{total}=2*228in=456in

Make the conversion from inches to feet.  Then, 456 inches to feet is:

(456in)(\frac{1ft}{12in})=38ft

riadik2000 [5.3K]

Step-by-step explanation:

you should only make one equation:

75 + 45x = 30 + 55x

subtract the 30 frim both sides, then subtract 45x from both sides. you are left with:

45 = 10x

Divide by 10 and get:

4.5 = x

After 4.5 hours, the cost is equal for either worker.

the 11th term in a geometric sequence is 48 and the common ratio is 4. the 12th term is 192 and the 10th term is what?
Soloha48 [4]

<u>Given</u>:

The 11th term in a geometric sequence is 48.

The 12th term in the sequence is 192.

The common ratio is 4.

We need to determine the 10th term of the sequence.

<u>General term:</u>

The general term of the geometric sequence is given by

a_n=a(r)^{n-1}

where a is the first term and r is the common ratio.

The 11th term is given is

a_{11}=a(4)^{11-1}

48=a(4)^{10} ------- (1)

The 12th term is given by

192=a(4)^{11} ------- (2)

<u>Value of a:</u>

The value of a can be determined by solving any one of the two equations.

Hence, let us solve the equation (1) to determine the value of a.

Thus, we have;

48=a(1048576)

Dividing both sides by 1048576, we get;

\frac{3}{65536}=a

Thus, the value of a is \frac{3}{65536}

<u>Value of the 10th term:</u>

The 10th term of the sequence can be determined by substituting the values a and the common ratio r in the general term a_n=a(r)^{n-1}, we get;

a_{10}=\frac{3}{65536}(4)^{10-1}

a_{10}=\frac{3}{65536}(4)^{9}

a_{10}=\frac{3}{65536}(262144)

a_{10}=\frac{786432}{65536}

a_{10}=12

Thus, the 10th term of the sequence is 12.
