Hello from MrBillDoesMath
Answer: 6.2 feet
Discussion:
The ladder and the wall form a right triangle. The length of the ladder, 20 in this case, is the hypotenuse of the triangle. Let "x" be the distance between the foot of the ladder and the building. Then from trigonometry,
cos (@) = length of adjacent side/ hypotenuse
or in our case
cos(72) = x / 20 => (multiply both sides by 20)
20 * cos(72) = x.
Using a calculator this becomes
20 * ( .3090) = 6.18 feet (approx) or 6.2 feet , rounded to the nearest foot.
Thank you,
Mr. B
0.8 is 20% of 4. This is because 20% of something occurs when something is divided by 5, since it is 1/5 of 100. You multiply 0.8*5, and you get 4.
The line through (3,6) and (3,15) is vertical so the perpendicular slope is a horizontal line.
y=7
6.23 times 10 superscript 12 is the greatest number.
We have given that,
6.23 times 10 Superscript 12
6.23 times 10 Superscript 8
6.23 times 10 Superscript negative 6
6.23 times 10 Superscript 3
We have to find
Which number is greatest
What is the greatest power of 10?
12
Therefore,
6.23 times 10 superscript 12 is the greatest number
It shows the 10 has been multiplied by itself more than times remaining option
Thus,
6.23 times 10 superscript 12 is the greatest number
