It is "FALSE". In the problem, the expression is a^b where the variable "a" is called the base and the variable "b" is called the "EXPONENT or power". So, from the given problem, it is incorrect the "b" is called numerator.
Volume of a pyramid =1/3B*H
B is Area of base here base is triangle
so Area of a triangle=1/2*b*h
=1/2*5*12
=30 cm^2
Volume=1/3*30*H
90=1/3*30*h
90*3/30=h
(volume is given)
h=9 cm
Since drapes have to be covered all over the window and the beneath of the window, both lengths have to be added.
(2 2/3) + ( 2 3/4)
(8/3) + (11/4)
(32+33)/12
65/12
5 5/12
Answer=B 4.8
We have a right triangle in the drawing so for the altitude we can use the pythagorean theorem. It's as follows...
a²+b²=c² (where a and b are the side lengths and c is the hypothenuse)
Lets input in the data that we have.
11²+b²=12²
simplify
121+b²=144
subtract 121 from both sides
b²=23
To solve for the missing side/altitude we just need to find the square root of 23
b=√23
b=4.79 or 4.8
Answer=B
