-32 should be the answer if you are owing more
Answer:
Step-by-step explanation:
to find the surface area we need to find the followng areas:
- area of a triangle and multiply it by 4 (because there are 4 triangles)
And once we have those areas, we add them to find the surface area.
Area of the square:
the formula to find the area of a square is:
where is the length of the side:
thus the area of the square is:
Area of the triangles:
the are of 1 triangle is given by
where is the base of the triangle: (the base of the triangle is the side of the square)
and is the height of the triangle:
thus, the area of 1 triangle is:
the area of the 4 triangles is (we multiply by 4):
finally we add the area of the square and the area of the 4 triangles to find the total surface area:
Answer:
Alexa drove an average of 52 miles an hour (mph).
Step-by-step explanation:
First, identify what you know:
1) Alexa drove 104 miles.
2) Alexa drove 104 miles in 2 hours.
So, we need to calculate how many miles she traveled in a single hour! To do this, we simply divide the number of miles driven, by the time driven.
104 miles/2 hours = 52 mph
On average, Alexa drove 52 mph, however, this is ONLY the average. It doesn't mean she drove 52 mph the entire time. She may have driven faster for 20 minutes, and then slower for 30. 52 mph is just the average speed.
Hope this helps! :)
Answer:
Step-by-step explanation:
f(x) = -3
To find (f + g)(x), we simply have to find f(x) + g(x) .
The number 3.456456 is a rational number, as the decimal digits of the number follow the 456 pattern.
<h3>What are rational numbers?</h3>
Rational numbers are the whole numbers plus decimals that can be represented by fractions, involving both positive and negative numbers.
Among examples of rational numbers, we have that:
- Non-terminating decimals in which the decimal digits follow a pattern.
The number used in this problem is given as follows:
3.456456...
Which is a rational number, because the decimal pattern is:
456.
Meaning that the sequence 456 repeats infinitely on the decimal digits.
Now, the number would be irrational if a different digit appeared on the pattern, for example:
3.4567456456...
