Answer:
30 in
Step-by-step explanation:
The enclosing rectangle is 4 by 10, so has a perimeter of ...
P = 2(L+W) = 2(10+4) = 28
The notch adds 2 inches to the perimeter, so the total of all side lengths is ...
28 +2 = 30 . . . inches
This problem is solely on right triangles, wherein the Pythagorean theorem may be applied. We must first find the angle of elevation of the flagpole using Tim's height and the difference between the shadow of the flagpole and Tim's distance from the flagpole. Therefore tan a = 1.65/(16.6-12.5) where a=21.68 degrees. We use this angle to determine the height of the flagpole. tan 21.68 = x/ 16.6 where x=height of flagpole=6.6 meters.
Answer:
I guess this is how to do it....
3×(1/3 of x + 8)=11.
use the 3 to multiply the numbers in the bracket.
3x+24=11.
3x=11-24.
3x=-13.
x= -13/3.
x= -4.33.
B.The function is decreasing when x<0 and increasing when x>0
79.2% is 0.792 as a decimal
