Answer:
Cost of purple carpet for Claire's bedroom is $1033.92.
Step-by-step explanation:
Given:
The dimension of bedroom are given as 16 feet and 18 feet.
Hence we can say that;
Length = 18 feet
width = 16 feet
Cost of carpet per square feet = $3.59
We will first find the area of the bedroom.
Area of bedroom can be calculated by multiplying length with width.
Area of bedroom = 
Hence Area of bedroom is 288 square feet.
Now we know that;
Cost of carpet per square feet = $3.59
Hence Cost of carpet for 288 square feet is ;
we will unitary method to find the same;
Cost of carpet for bedroom = 
Hence Cost of carpet for Claire's bedroom is $1033.92.

Answer:
Step-by-step explanation:
Let the total budget be x.
<u>Given condition:</u>
73% of total budget = 949
73% of x = 949
<u>Key:</u>
of => to multiply
% => out of 100
<u>Solution;</u>
![\displaystyle \frac{73}{100} \times x = 949\\\\Multiply \ \frac{100}{73} \ to \ both\ sides\\\\x=949 \times \frac{100}{73} \\\\x = \frac{94900}{73} \\\\x = \$ 1300\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B73%7D%7B100%7D%20%5Ctimes%20x%20%3D%20949%5C%5C%5C%5CMultiply%20%5C%20%5Cfrac%7B100%7D%7B73%7D%20%5C%20to%20%5C%20both%5C%20sides%5C%5C%5C%5Cx%3D949%20%5Ctimes%20%5Cfrac%7B100%7D%7B73%7D%20%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B94900%7D%7B73%7D%20%5C%5C%5C%5Cx%20%3D%20%5C%24%201300%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
Let
be the number of hours that the waitress works in the evening.
We know for our problem that she works
in the afternoon and that she works <span>1.75 hours less in the afternoon than in the evening, so:
</span>
<span>Since </span>
, we can rewrite our expression:
We can conclude that she works 3.375 hours in the evening, or expressed as a mixed fraction:
hours.
√3 - √169 =?
√3 - √(13)² = √³ - 13 or equal √3 + 13 since √169 = + or - 13
