Answer:
c
Step-by-step explanation:
Answer: 19 ft
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (in this case the length of the ladder) and a and b are the other sides.
Replacing with the values given:
20^2 = (4 1/2)^2 + x^2
400=20.25 + x ^2
400-20.25 = x^2
379.75 = x^2
√379.75 = x
x = 19.48
x= 19 ft

Nonviolent resistance is not to defeat anyone, but to create friendship and understanding. Instead of destroying the opponent.
Answer:

Step-by-step explanation:
The formula of a lateral area of a cone:

r - radius
l - slant height
The formula of a surface area of a cone:

We have r= 9mm and l = 17mm. Substitute:


Total =45
Black hair=21*360/45=168
Blonde=11*360/45=88
Brown=9*360/45=72
Red=4*360/45=32
