We are give the equation of the perimeter of the triangle as follows:
2a + b = 15.7
where b represents the base.
Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a
We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm
Answer:
B
Step-by-step explanation:
Set up the equation
z = 
Plug in the numbers to find the value of k
3 = 
12 = 4k
3 = k
Solve to find the value of z
z = 
z = 
z = 48/9
z = 16/3
The median means the middle number.
First, you put them in order from least to greatest.
Then, you look to see which number is in the middle.
Since there are only four numbers given, you have to go in between two of the numbers.
The median is in between 22,000 and 24,000.
20,000 22,000 _ 24,000 26,000
The number that is equally between 22,000 and 24,000 is 23,000.
The median for the set of data is $23,000.
Hope this helps!
Answer:
3x^2
Step-by-step explanation:
Given:
(3x) * {(1/x)^-4 }* (x^-3)
=(3x) * {1 ÷ (1/x)^4} * {1/x^3}
=(3x) * {1(x/1)^4} * (1/x^3)
=(3x) * (x^4) * (1/x^3)
=(3x) (x^4) (1) / x^3
Multiply the denominators
=3x^5 / x^3
Can also be written as
=3*x*x*x*x*x / x*x*x
Divide the x
= 3*x*x / 1
=3x^2
