= 250 - 45
= 205
Therefore, Mr. Alvarez drop off 205 ballots.
<u>Answer:</u>
a = 8.1
<u>Step-by-step explanation:</u>
Use the cosine rule:
![a = \sqrt{b^2 + c^2 -2 bc \space\ cosA }](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%7Bb%5E2%20%2B%20c%5E2%20-2%20bc%20%5Cspace%5C%20cosA%20%7D)
Substituting the values:
![a = \sqrt{10^2 + 12^2 -2(10)(12) \space\ cos 42 \textdegree\ }](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%7B10%5E2%20%2B%2012%5E2%20-2%2810%29%2812%29%20%5Cspace%5C%20cos%2042%20%5Ctextdegree%5C%20%7D)
⇒ ![a = \sqrt{4 \space\ cos 42\textdegree\ }](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%7B4%20%5Cspace%5C%20cos%2042%5Ctextdegree%5C%20%7D)
⇒ ![a = 8.1](https://tex.z-dn.net/?f=a%20%3D%208.1)
Hello
To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2.
Answer:
5 ft
Step-by-step explanation:
Let the height of the previous jump be represented by j. Then 1.1j = 5.5 ft.
Dividing both sides by 1.1, we get j = 5 ft. This was the height of the previous jump.
