We are given with two current costs : $3,450 for tables and $3,950 for chairs .The total cost then is equal to $7,400. This is said to be 4% more than he spent last year. so last year's expenses should be <span> $7,400 / 1.04 equal to $7115.39. The cost last year is expected to be less</span>
Answer:
A. 2.18 × 10^4
Step-by-step explanation:
2.18 × 10^4
10^4 = 10000
2.18 × 10000 = 21800 which is less than 22874
Answer:
The answer is ![a = \frac{15}{4}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B15%7D%7B4%7D)
Step-by-step explanation:
We have to:
![cos(\theta) = \frac{adjacent\ side}{hypotenuse}](https://tex.z-dn.net/?f=cos%28%5Ctheta%29%20%3D%20%5Cfrac%7Badjacent%5C%20side%7D%7Bhypotenuse%7D)
So, if we take the 60 degree angle of the smallest triangle, we have to:
![cos(60) = \frac{a}{x}](https://tex.z-dn.net/?f=cos%2860%29%20%3D%20%5Cfrac%7Ba%7D%7Bx%7D)
We do not know x. But if we take the sine of the angle of 30 degrees and the main triangle we have:
![sin(30) = \frac{x}{15}\\\\x =\frac{15}{2}](https://tex.z-dn.net/?f=sin%2830%29%20%3D%20%5Cfrac%7Bx%7D%7B15%7D%5C%5C%5C%5Cx%20%3D%5Cfrac%7B15%7D%7B2%7D)
Then:
![cos(60) = \frac{a}{\frac{15}{2}}](https://tex.z-dn.net/?f=cos%2860%29%20%3D%20%5Cfrac%7Ba%7D%7B%5Cfrac%7B15%7D%7B2%7D%7D)
![a = cos(60)\frac{15}{2}](https://tex.z-dn.net/?f=a%20%3D%20cos%2860%29%5Cfrac%7B15%7D%7B2%7D)
![a = \frac{15}{4}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B15%7D%7B4%7D)
