3 1/4 - 1 7/8
First, subtract the whole numbers (3 - 1 = 2):
= 2 1/4 - 7/8
Convert 1/4 to 2/8:
= 2 2/8 - 7/8
Borrow 1=8/8 from the 2:
= 1 10/8 - 7/8
Subtract 7/8 from 10/8:
= 1 3/8
The answer is 1 3/8
Alternatively, use improper fractions:
3 1/4 = 13/4 = 26/8
1 7/8 = 15/8
26/8 - 15/8 = 11/8 = 1 3/8
Answer:
35%
Step-by-step explanation:
35%+30%= 65%
65%+35% = 100%
Answer:

Step-by-step explanation:
(1) As definition, the area (
) of a circle is calculated by:
x
with
is radius of circle.
(2) The relation between radius (
) and diameter (
) of a circle is:
= 2 x 
(3) Applying the Pythagorean theorem for a square with sides of length
,
the relation between side
and diagonal
is:

=> The diagonal (
) of that square is calculated by:
= 
(4) The square fits exactly inside a circle, with each of its vertices being on the circumference of the circle.
Applying the theorem of inscribed angle in a circle, the measure of arc BD is twice as the measure of inscribed angle BAD.
In other words, the measure of arc AC = 2 x 90 = 180 deg, or half of circle.
It means that the diagonal BD is coincide with a diameter of circle.
=> 
or
x
= 
or
= 
Substitute
back into original formula used for calculating the area of circle:
=> A =
x
=
x 
=>
x 
=>
x
=
x
= 5.97 cm

Answer:
[0,50]
Step-by-step explanation:
The function takes from value the distance from the plane to the building, and returns the height of the plane at that point in feets. Assuming that the plane goes always down, it will always be up to the height of the building. Note that the horizontal distance the plane travels at any point is equivalent to the distance of the plane with the building at that point, because the building is perpendicular to the ground. So, at the end of the travel the plane will be 50 feets away from the building. SInce it starts at 0 distance, then the domain of the function is [0,50]
Another written expression is 5x+25
