Answers

Answer 1

Answer: if he worked 17 hrs for 187. it is saying how many groups of 17 are in 187. so 187/17 = $11 per hour

Explain how you can find the height of a cylinder if you know the diameter and the volume

Answers

Calculate the area of the base of a cylinder, and then divide the volume by it.

Ok so basically the formula of the volume of a cylinder is:
V = Area of base × height of cylinder
V = $\pi$ r²h

If we know the diameter, we then know the radius
Radius is half the diameter.
r = $(d)/(2)$

We use the given, We plug in the given formula and find the area (since we know the radius)

Volume(given) = Area(found) × Height(unknown)
We divide the volume by the area to find the height.

$(Volume)/(Area.of.base)$ = height of prism

This is how we find the unknown height of the prism.

Find the common ratio of the geometric sequence: −320,80,−20,5,…

Answers

With geometric sequences, if you divide a term by the term before it you'll get the common ratio. That's how they are all constructed, and in this problem:

$(80)/(-320)=-(1)/(4)$

So -1/4 is our common ratio.

The common ratio of the geometric sequence −320, 80, −20, 5,… is -1/4 or -0.25.

What is a sequence?

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have a geometric sequence:

−320, 80, −20, 5,…

As we know, the geometric sequence or progression follows a certain rule of arithmetic.

The common ratio = second term/first term or

First term = -320

Second term = 80

= 80/(-320)

= -1/4

The common ratio = -1/4 or -0.25

Thus, the common ratio of the geometric sequence −320, 80, −20, 5,… is -1/4 or -0.25.

How do I identify a standard form and vertex form in a quadratic equation?

Answers

Answer:

the standard form of a quadratic equation is ax² + bx + c

the vertex form is a(x - h) + k where h & k are the x and y coordinates

to get from standard form to vertex form, you would have to follow this formula to find h:

-b/2a

plug in the values, and you will get the value of h.

to get k, you plug in the value you have just found in the above formula into the original equation, and that is the value of k.

the a in the vertex form is the value of a in the standard form

so an example of this would be: x² + 2x + 4 where a = 1, b = 2 c = 4

to get this into vertex form we will use the formula -b/2a and solve:

-2/2(1) --> -2/2 = -1

now we plug in the value we found into the original equation wherever x is

(-1)² + 2(-1) + 4 --> 1 - 2 + 4 = 3

we have both h and k, and we will put this into vertex form:

a(x - h)² + k turns into ---> (x + 1)² + 3

why x+1 and not x-1? the original equation has a negative sign, and the result we have is negative. this conflicts with the original equation and is therefore turned into a positive 1

where did a go? since a = 1, we do not need to write it, if a was equal to 2 then we would write the 2 in front

Dave wants to install carpet in his room. The room is rectangular in shape with a length of 16 feet and a width of 12 feet. If the total cost of installing the carpet is $288, what is the unit price of carpet per square foot?

Answers

Hello there!

If you multiply 12 by 16, you get 192. Divide 288 by 192 ( being the total amount of square feet. ) and you get 1.5, essentially being $1.50 per square foot.

To check this, multiply 192 by 1.5 and you will get 288.

Ok so the width is 12 and the length is 16 so we will multiply those: 12 x 16=192 so now we divide 288 by 192= 1.5 or %1.50 so the answer is %1.50 per square foot Hope this helped!!

Answers

Answer:

B, E

Step-by-step explanation:

Given the first function:

$y=-2x+(2)/(3)$

A Linear System with no solutions is graphically represented by two parallel lines, therefore with the same slope. So in this case, m has to be equal to -2.

And to this inconsistent system, if the linear parameter is not so relevant. So if m=-2 then b may be either equal to -1/3 or -2/3 according to the options.

Given the alternatives

No Solution System:

$\left\{\begin{matrix}y=-2x+(2)/(3) & \n y=-2x-(1)/(3) & \end{matrix}\right.$
