Answer:
33.49 cubic inches
Step-by-step explanation:
Answer:
UP=78
Step-by-step explanation:
TP=TU+UP
103=2x+3+6x+12
103=8x+15
103-15=8x
8x=88
x=11
UP=6x+12
UP=6(11)+12
UP=66+12
UP=78
The square root of a whole number will be rational if the whole number is a perfect square (i.e 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144 etc) and irrational otherwise.
Rational number is a number that can be described as m/n
so a fraction can be a rational number, 0.8=4/5
Irrational numbers can't be written as a fraction
The part about the number having to be a perfect square is still correct, if it's not a prefect square than it will just keep going(a decimal that never ends)
for example the square root of 0.64 is 0.8
and the square root of 10 is 3.162277...
as you can see the 0.64 one ends and is rational, whereas the 10 one just keeps going and is irrational.
Complete Question:
Which of the following statements is not true?
Choose the incorrect statement below.
Answer:
B. A system of linear equations in two variables must have at least one solution.
Step-by-step explanation:
A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional. Thus, the graph of a linear function is a straight-line and its slope is always constant.
Similarly, a linear equation is an algebraic equation of the first order with two variables and each of its term having an exponent of one.
Generally, a system of linear equations in two variables must have at least two solution.
For example, y = 2x + 1 is a linear equation.
a. To find the value of y;
When x = 0
y = 2(0) + 1
y = 2 + 1
y = 3
b. To find the value of x;
When y = 0
0 = 2x + 1
2x = -1
x = -½
