So discount means less so find 5%
remember that percent means parts out of 100 so
5%=5/100=1/20
find 1/20 of 60
'of' means mulitpy in math
1/20 ties 60=3
5%=3
discoutn is 3
subtract 3 from 60
60-3=57
she paid $57
Answer:
Function A: y = 2x + 7
Function B: y = 3x + 4
This means function A has a greater y-intercept because 7 > 4
Answer:
true
Step-by-step explanation:
geometry
The circumference of a circle is calculated using the following equation:

Where d is equal to the diameter (the length of a straight line from one side of the circle to the other side).
We know that the diameter of the circle given (also known as AB) is equal to 20 cm.
We can then plug this into the equation and solve for the circumference:

Since the question asks for the answer to be in terms of

, this is as far as we need to go. So
the circumference of the circle is:
or D.
Answer:


Step-by-step explanation:
Given



See attachment for illustration
Solving (a): Trigonometry ratio to calculate h.
From the attachment, we have:

Multiply both sides by d


Rewrite as:

Solving (b): The value of h
We have:


So:
