Answer:
False
Step-by-step explanation:
It is false because the absolute value signs mean that |-3| is actually positive 3. Absolute values are always positive. So, now you have 3 is less than or equal to 0, which is false because 3 is greater than 0.
For the spinner with 3 sectors, the total number of outcomes for 3 spins is 27.

What is the combination?</h3>
A combination is a mathematical technique that determines the number of possible arrangements.
Let's we have to define
A, B, and C, as the regions in the spinner.
So, we spin it 3 times, and for each of these times there are 3 outcomes, so the outcomes will be of the form:
The outcome of spin 1, the outcome of spin 2, outcome of spin 3.
The total number of different outcomes will be:
3^3 = 27

Answer: The perimeter is 30ft.
Step-by-step explanation:
Let's define:
L = length of the longer side.
S = length of the shorter side.
P = perimeter
we know that for a common rectangle:
P = 2*S + 2*L
We aso know that:
L = 2ft + (1/3)*P
S = (1/10)*P
L = S + 9ft.
So we have a system, let's find the perimeter only using this system (So i will ignore the equation for the perimeter of a rectangle)
First, we can replace the third equation in the first equation, now we have a system with only two equations:
S + 9ft = 2ft + (1/3)*P
S = P/10
Now we can replace the second equation in the first equation, and get:
P/10 + 9ft = 2ft + P/3
Now let's solve this for P.
9ft - 2 ft = P/3 - P/10
7ft = P( 1/3 - 1/10) = P*( 10/30 - 3/30) = P*(7/30)
(30/7)*7ft = P = 30ft.
The perimeter is 30ft.
Answer:
1273.4
Step-by-step explanation:
1273.39
thousands, hundreds, tens, ones . tenths hundredths
We are rounding the 3 so we look at the 9
9 is greater than or equal to 5 so we will round the 3 up
1273.4
