Hi there, just multiply all 4 numbers. 5.3*8*8*4=1356.8
I can answer the first four
1 is 40%
2 is 60
3 is $1.35
4 is 6%
Answer:
6/7x+5/2y
Step-by-step explanation:
I actually don't know
You have an angle of elevation of 3 degrees and you're 2000 ft from base of 30 story building.
<span>Draw a picture of this. Then tan(3) = ht of bldg/2000 </span>
<span>I get a height of 104.82 ft rounded to 2 dp. </span>
<span>5. Ok. use the Pythagorean Theorem here to find the hypotenuse of the right triangle </span>
<span>hypt = sqrt(50^2 + 9^2) </span>
<span>Now sine of the angle of elevation is 50/hypt. = 0.984 or 0.98 to 2 dp.</span>
