Answer:
7 feet
Step-by-step explanation:
Volume of a cyclinder = πr^2h
Volume of a cyclinder = 1952
π = 3.14
r = ?
h = 2r
Volume of a cyclinder = πr^2h
1952 = 3.14 * r^2 * 2r
1952 = 3.14 * 2r^3
1952 = 6.28r^3
Divide both sides by 6.28
r^3 = 1952 / 6.28
= 310.83
r^3 = 310.83
Find the cube root of both sides
r = 6.77 feet
Approximately 7 feet
The answer is 4.5 because you are multiplying 1.5 times 3 = 4.5
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
Alright so lets break this down!
What we are looking at is:
y = 3x - 4
the question is
<em>what is the value of x when y = 5?</em>
This means all we have to do is plug in 5 for y and solve for x
y = 5
x = ?
therefore,
5 = 3x - 4
Now some algebra,
5 + 4 = 3x
9 = 3x
9/3 = x
<em>3 = x</em>
Now our concluding statement:
The value of x is 3 when y is equal to 5
Sometimes all you have to do is turn words into numbers and numbers into words!
Good luck! I hope this was helpful.
