If it's an isosceles triangle, the answer should be 87*42yd. In a right triangle, the area is (height*base)/2. if the height perfectly divides the triangle in half, there's no need to divide h*b by 2.
Answer:
1) 20%
2) Choice a.
Step-by-step explanation:
1) is the population initially.
is the population after a year.
represents the population increase factor.
So let's evaluate that fraction:
0.2=20%
2) Let's figure out the population growth in terms of months instead of years.
We want t to represent months.
A full year is 12 months, in a full year we have that
So we want a new P such that since 12 months equals a year.
Let's look at the functions given to see which gives us this:
a)
b)
c)
d)
So a is the function we want.
Also another way to look at this:
where is in years.
where is in months.
And
Her change will be $16.22 since 20 +20 is 40 and 40 - 23.78 is 16.22
Answer:
Choice D for Angle R
70 degrees for Angle P
Step-by-step explanation:
Google "central angles and inscribed angles geometry" for an explanation.
It's actually a poorly worded question.
