what is the volume? I need it ASAP
Answer: it is [tex]v = 4/3 \pi r 3[/tex]
Step-by-step explanation:
Evaluate the expression when x=10, y=−2, and z=−5.
[tex]\frac{−x2+6z}{y}[/tex]
Step-by-step explanation:
x=10, y=-2, z=-5
(-x2+6z)/y
= [-(10)2+6(-5)]/-2
=-20-30/ -2
=-50/-2
=25
I'm really not sure about this answer so let me know if in wrong :)
Find the amount of interest on $6200 with an interest rate of 3.5% a year. How much do I have in total for 4 years?
Answer:
$868
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.5%/100 = 0.035 per year,
then, solving our equation
I = 6200 × 0.035 × 4 = 868
I = $ 868.00
The simple interest accumulated
on a principal of $ 6,200.00
at a rate of 3.5% per year
for 4 years is $ 868.00.
1. Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.
2. Write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. Show all your work, including the points used to determine the slope and how the equation was determined.
3. What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
4. Test the residuals of two other points to determine how well the line of best fit models the data.
5. Use the line of best fit to help you to describe the data correlation.
6. Using the line of best fit that you found in Part Three, Question 2, approximate how tall is a person whose arms span is 66 inches?
7. According to your line of best fit, what is the arm span of a 74-inch-tall person?

4. What are the 2 types of ways Linear Functions are represented ?
Answer:
There are several ways to represent a linear function, including word form, function notation, tabular form, and graphical form. We will describe the train's motion as a function using each method
Step-by-step explanation:
There are three standard forms for linear functions y = f(x):
f(x) = mx + b (The "slope-intercept" form),
y - yo = m(x - x0) or, equivalently, f(x) = y0 + m(x - x0) (The "point-slope" or "Taylor" form), and.
Ax + By = C (The "general form") which defines y implicitly as a function of x as long as B 0.

What is the equation of the line that passes through the point (-5,2)(−5,2) and has a slope of 4/5?
Answer:
30 = 5y - 4x or 6 + (4x/5) = y (in mx + c = y form)
Step-by-step explanation:
slope =
[tex]y_{2}[/tex] - [tex]y_{1}[/tex]/ [tex]x_{2}[/tex] - [tex]x_{1}[/tex]
now, [tex]y_{2}[/tex] = 2
[tex]x_{2}[/tex] = -5
insert the values of these two in the slope formula and equate it with 4/5.
by cross multiplication, obtain equation.
the equation is 30 = 5y-4x.
hope this helps you!
Answer:
The answer is
[tex]y = \frac{4}{5}x + 6[/tex]
Step-by-step explanation:
We'll be doing the y = mx + b form.
We are gonna substitute first, then solve.
[tex]y = mx + b \\ 2 = \frac{4}{5} ( - 5) + b \\ 2 = - 4 + b \\ \frac{ + 4 \:= + 4\: \: \: \: \: \: \: \: }{6 = b} [/tex]
Using the information given and gathered:
[tex]y = \frac{4}{5}x + 6[/tex]
Which number line shows a point at 0.58
Answer:
D
Step-by-step explanation:
Starting from 0, each tick mark going towards the right is .1 .58 is between .5 and .6, but closer to .6. Looking at all the options, D is the correct answer.
Answer:
I believe it's the last one.
Step-by-step explanation:
so 1.0 is the whole line together. and half of that would be .50 so if it's .58 it will be closer to the 6th tick mark on the line. so therefore will be the last one!!
Hope this helps! Have a good day! :))
Ricardo has 3 rolls of tape. Each roll has 8 and 1 third feet of tape. It takes 2 and 2 thirds feet of tape to close a box completely.
What is the total number of boxes that Ricardo can completely close using these 3 rolls of tape?
Answer: 9 boxes
Step-by-step explanation: multiplying the 8 and one third by the number of tape rolls gets you 25, then divide that by 2 2/3 to get an answer of 9.375, and because you cant colse the box with the extra .375, you have to round down, getting you to your answer of 9.

Solve: 3x=12
1. 36
2. 4
3. 5
4. 3
Answer:
The answer is 4.
Step-by-step explanation:
This is a basic one-step algebra problem.
We have: 3x = 12.
We would like find what x equals. In order to do that, we must have the x variable on one side of the equals sign, and the rest of the numbers on the other side. In other words, we have to isolate the x variable away from its coefficient.
To do this, we must divide BOTH sides of the equation by 3. This would mean that the 3 on the left side of the equals sign cancels out, totally getting rid of the 3.
Here's what it should look like: [tex]\frac{3x}{3} = \frac{12}{3}[/tex]
Now, we actually divide both sides now, which should look like this: [tex]x = 4[/tex]
This is because 3 divided by 3 is 1, and 12 divided by 3 is 4.
Hence, our solution for x is 4. Hope this helped!

Answer:
[tex]1\frac{1}{4}[/tex] kilograms of oranges left
Step-by-step explanation:
1) We know that originally Jameson had [tex]3\frac{1}{2}[/tex] kilograms of oranges, then he gave [tex]2\frac{1}4}[/tex] away. So let's subtract and set up this equation to find out how many kilograms of oranges he has now:
[tex]3\frac{1}{2} - 2\frac{1}{4}[/tex]
2) Then convert the mixed numbers to improper fractions:
[tex]\frac{7}{2} - \frac{9}{4}[/tex]
3) Next, let's change [tex]\frac{7}{2}[/tex] so that its denominator is 4 by multiplying it by [tex]\frac{2}{2}[/tex]. This should give us [tex]\frac{14}{4}[/tex] as our result, and so our equation now looks like this. Continue to simplify.
[tex]\frac{14}{4} - \frac{9}{4}[/tex]
[tex]\frac{5}{4}[/tex]
4) Then convert [tex]\frac{5}{4}[/tex] to a mixed fraction and that is our answer:
[tex]1\frac{1}{4}[/tex]

Marta runs a mandarin-orange fruit stand. She is talking to an employee, Maribel, on the phone and trying to tell her the equation needed to figure out how many oranges to send to a certain customer.
The equation is 50 + one-half m = 120. Which statement should Marta say that will communicate the correct equation? Select all that apply.
Fifty times the number of oranges is half of one-hundred-and-twenty.
Fifty more than half the number of the oranges is one-hundred-and-twenty.
The difference of fifty and half of the number of oranges is one-hundred-and-twenty.
The sum of fifty and half the number of oranges is the same as one-hundred-twenty.
Fifty more than half of the number of oranges.
Answer:
All the answers that apply are:
Fifty more than half the number of oranges is one-hundred-and-twenty.
The sum of fifty and half of the number of oranges is the same as one-hundred-and-twenty.
Step-by-step explanation:
This is because the equation is 50 + 1/2 = 120. Both of the statements are equivalent to the equation.
