To find the volume,we would first need to find the height of square pyramid, by it's base edge and slant height using Pythagoras theorem:

We can then use the pyramid formula to find the volume:

In this case,the volume will be:
10×_/69×1/3
=27.68874...
≈27.7 units^3
Hope it helps!
Answer: B. 11%
Step-by-step explanation:
Let A = Event that students eat breakfast in the morning.
B= Event that students floss their teeth.
We are given P(A)=57%=0.57
P(B)=80%=0.80
P(A∩B) = 46% =0.46
Now, the probability that a student from this class eats break feast but does not floss their teeth :-

Hence, the probability that a student from this class eats break feast but does not floss their teeth= 11%
Answer:
y - 2 = -
(x - 7)
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 4 ← is in slope- intercept form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
= -
= - 
The equation of a line in point- slope form is
y - b = m(x - a)
m is the slope and (a, b) a point on the line
Here m = -
and (a, b) = (7, 2), thus
y - 2 = -
(x - 7) ← equation of perpendicular line
