<h3>
Answer: $59.25</h3>
========================================================
Explanation:
There are two approaches
Method 1
25% of 79 = 0.25*79 = 19.75
Mary saves $19.75 and the price before tax is 79 - 19.75 = 59.25
-----------------------------
Method 2
She saves 25% so she must pay the remaining 75%
75% of 79 = 0.75*79 = 59.25
This is a slight shortcut, and it's very useful when it comes to chaining multiple discounts together.
Answer:
r = 18/pi
or approximately 5.7325 inches
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
36 = 2*pi*r
Divide each side by 2 pi
36/(2pi) = r
18/pi = r
Letting pi = 3.14
18/3.14
5.732484076 = r
In the 
plane, we have 
everywhere. So in the equation of the sphere, we have
which is a circle centered at (2, -10, 0) of radius 4.
In the 
plane, we have 
, which gives
But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the 
plane, 
, so
which is a circle centered at (0, -10, 3) of radius 
.
Answer:
14
Step-by-step explanation:
Because 1/4 of women have a disability, you would expect 1/4 * 56 = 14 women to have a disability out of 56 women.
