You need to find the root of 69 since the length and width are multiplied to get the area, therefore it would be 8.3 inches.
The slope is -2. In context to this problem, the candle will burn away 2cm of its length every hour.
Answer:
Triangle 1: x = 80 degrees, acute
Triangle 2: x = 10 degrees, right
Step-by-step explanation:
Triangle 1:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation:

Solve for x:

So, x = 80 degrees
Because all the angles are less than 90 degrees, this is an acute triangle.
Triangle 2:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation (with the right angle given):

Solve for x:

So, x = 10 degrees
Because there is an angle measuring 90 degrees, this is a right triangle.
Answer:
C: 70 Mins
Step-by-step explanation:
1, 20ft*15ft=300ft^2
2, 30ft*25ft=750ft^2
3, 750ft-350ft=450ft^2
4, 450 ft^2 = 30 mins
5, 350ft=750ft=1050ft^2
6, 1050/450=2.3333
7, 30*2.3333=70
8, 70 mins
For this case we are going to assume the following:
m: whole number greater than zero.
n: integer greater than zero.
Where,
n> m
According to these assumptions, the percentage of growth is given by the following formula:
