They are not equivalent because
4:5
x2 x2
=8:10
it does not equal 8:12
your welcome:)
For this case, the first thing to do is find the area of the trapezoid.
We have then:
Where,
b1: b2: Trapezoid bases
h: height of the trapezoid
Substituting values we have:
Then, the cost per square foot is given by:
Answer:
The new carpet for the room will cost:
C = 1072.5 $
(0,0) is the cost of 0 bags of peanuts. This is because the x-axis is labeled "Bags of Peanuts", and an x-value of 0 implies 0 bags of peanuts.
Answer: The value of x is 1
Step-by-step explanation:
10x + 5 = 15
Collect the like terms which in this case are the whole numbers "5" and "15")
10x = 15 - 5
10x = 10
Divide both sides by 10
10x/10 = 10/10
x = 1
Thus, the value of x is 1
Part A is a rational number, so adding another rational number (1/3) gives a rational result.
Part B is 2/3, so adding 1/3 gives a sum of 1, which is still a rational number.
Part C is 2*pi, which is irrational, and adding 1/3 gives a sum of 2*pi + 1/3, which still cannot be simplified into a rational expression.
Part D is an irrational number, and 1/3 - sqrt(17) also cannot be simplified into a rational number, so this is irrational.
Therefore the correct answers to this are C & D.
