A cylinder has volume 45 pi and radius 3. What is its height?

Answers

Answer 1

Answer:

Height = [tex]\frac{5}{\pi }[/tex]

Step-by-step explanation:

V = Volume

r = Radius

h = Height

[tex]h=\frac{V}{\pi *r^{2} }[/tex]

[tex]h=\frac{45}{\pi *3^{2} }[/tex]

[tex]h=\frac{5}{\pi}[/tex]

Can someone help me answer these two questions

Answers

Answer:

C) 7=y=5x+11

B) m=-4/5, b=13/5

Step-by-step explanation:

Problem 1:

A function is linear if its slope is constant and/or its graph is straight (that means 1-degree polynomials only). Therefore, C is the only correct answer.

Problem 2:

Convert to slope-intercept form (y=mx+b):

4x+5y=13

5y=13-4x

y=13/5-4/5x

y=-4/5x+13/5

Now we can see that since the original equation is in slope-intercept form (y=mx+b), the slope, m, is -4/5, and the y-intercept, b, is 13/5, making option B the correct answer.

Each month Marla pays a $30 cell phone bill from her bank account. At the
end of one year, what is the change in the amount of money in Marla's account
because of her cell phone bill? Write a multiplication equation to represent the
problem. Explain what the product represents.

Answers

Answer:

-$360.00 change

Step-by-step explanation:

Now there is either some information missing, like her starting total in the bank; or they want you to explain the net change.  But the way the question is worded it is stating she is paying $30 over 12 months.  This means she has paid $360.00 in that 12 months aka 1 year.  Her bank account should have had a balance.  So you could technically say B for balance.  B-30*12.  To get your answer.  Although there are many ways to write an equation expression of this question.  If you know the starting balance then it's better.  But you could assume her starting balance was $0.  Which would be 0-30M*12 where M could represent monthly.  And the same answer would occur of 360.  Is there more information?

30*12= X (x equals the total paid)

X-30*12 (if x is her balance before paying any money)

Answers

The expression that has a term with a coefficient of 6 is бу.

Option A is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The term "coefficient" refers to the numerical factor that is multiplied by a variable or variables in a term.

Out of the given expressions, only one has a term with a coefficient of 6, which is:

6y

Thus,

The expression that has a term with a coefficient of 6 is бу.
