E = mc2. An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.
123.456 RONDED TO THE NEAREST HUNDREDTH.
Answer:
123.46
The total would be 14.65, if she tips 15% of her cost 12.74 then it would be a tip of $1.91 adding that to $12.74 you get 14.65, hope this helps!
The length of UV is 19.7 ft.
<u>Solution:</u>
The given 
is a right triangle because W is 90 degrees. VW is adjacent to V and UV is the hypotenuse. Adjacent any hypotenuse use the cosine function.
Refer the image attached below for the image of the triangle.
plug in known values
The value of cos(72°) is 0.309
On substituting the above value in (1) we get,
Therefore, the required measure is 19.7 ft.
Just simplify the proportion.
300 to 225
divide by 25 on both sides
12 : 9
Divide by 3 on both sides
4:3
Since we cannot reduce any further, the answer is C. 4:3
