Answer:
The total surface area of a regular pyramidis the sum of the areas of its lateralfaces and its base. The general formula for thelateral surface area of a regular pyramidis where p represents the perimeter of thebase and SI the height of inclination.
V = ( 9*2 ) / 3 ;
v = 18 / 3 ;
v = 6 ;
a. is the right answer;
( 119.5 / 151 ) * 100 = 11950 / 151 = 79.1 ;
The percent is 79.1%;
c. is the right answer;
1 - (40/100)*1 = 1 - 2 / 5 = 3 / 5 = 0.60 ;
d. is the right answer.
Answer:
The slope that is perpendicular to the line will be:

Step-by-step explanation:
Given the equation

We know that
is the slope-intercept form of a line where m is the slope and b is the y-intercept.
So, writing the equation in the slope-intercept form


here
∵
As we know that for perpendicular lines, one slope is the negative reciprocal of the other.
Therefore, the slope that is perpendicular to the line will be:

Answer:
60
Step-by-step explanation:
Area = ((a+b)/2)h=((7+13)/2)*6=60
Answer:
+5x-36
Step-by-step explanation:
To multiply binomials there are 2 ways. F.O.I.L., or the box method.
I will use the box method, and I hope it helps you!
After looking at the picture, this is not the answer quite yet.




Subtract 4x from 9x.
9x-4x=5x
So, the answer will be
+5x-36
