3) A linear equation to represent this would be 205 = 10x + b
x is days passed, which is 10, and b is the original amount.
10 times 10 is 100, so we now have 205 = 100 + b
Subtract 100 from both sides to get 105 = b, which is the starting amount.
The rate of change is 10, however many cans brought per day.
4) So it appears that for every 5 minutes she frosts 4 cupcakes, which means the rate of change is 4/5 using rise over run.
Subtract 4 from 28 to get the starting amount 5 minutes earlier.
The starting amount of frosted cupcakes is 24.
5) Every 3 months he gets 9 more CDS. So, every month he gets 3 new CDs.
That means the slope is 3.
Subtract 9 from 18 to get the starting amount.
The starting amount of CDs is 9.

Hope this helps!

Mr. Hanky has 5 rolls of butcher paper. If you roll out a whole roll the paper would

KiRa [710]

$8,262ft^2$ of a single roll . Mr. Hanky have 5 roll so Total Area = $8,262(5) = 41,310$ . So , $41,310ft^2$ paper does Mr. Hanky have

<u>Step-by-step explanation:</u>

Here we have , Mr. Hanky has 5 rolls of butcher paper. If you roll out a whole roll the paper would measure 510 yards long. If the paper is 1.8 yard wide .We need to find that how many total square feet of paper does Mr. Hanky have . Let's find out:

We know that when butcher paper will be unfolded it will be in form of a rectangle with dimensions as :

$Length = 510yards\\Breadth =1.8 yards$

So , Area of rectangle = $Length(Breadth)$

⇒ $Length(Breadth)$

⇒ $510(1.8)$

⇒ $918yards^2$

But , $1 yard = 3 feet$

⇒ $918(3ft)^2$

⇒ $8,262ft^2$

Therefore , $8,262ft^2$ of a single roll . Mr. Hanky have 5 roll so Total Area = $8,262(5) = 41,310$ . So , $41,310ft^2$ paper does Mr. Hanky have .

I will be really happy if you help me out! :)

Answer/Step-by-step explanation:

#8. Using the geometric mean theorem formula, h = √xy, where,

h = x

x = 4 and y = 16

Plug in the values

x = √(4*16)

x = 8

#9. Using the geometric mean formula, h = √xy, where,

h = y

x = 5 and y = 8

Plug in the values into the formula:

y = √(5*8)

y = √40

y = 6.3 (nearest tenth)

#10. Using the geometric mean formula, h = √xy, where,

h = 18

x = 12 and y = y = ???

Plug in the values into the formula:

18 = √(12*y)

Square both sides

18² = 12y

324 = 12y

Divide both sides by 12

27 = y

y = 27

CAN SOMONE PLEASE HELP ME OFFERING BRAINLYIST THINGG Determine the range of the function.

KonstantinChe [14]

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values

What are the zeros of the function f(x) = x^4 - x² - 2?

vaieri [72.5K]

Answer:

$x= i\\\\ x = -i \\\\x=\sqrt 2\\\\x = -\sqrt 2$

Step-by-step explanation:

$~~~~~~x^4 -x^2 -2=0\\\\\implies x^2 \cdot x^2-2x^2 +x^2 -2 = 0\\\\\implies x^2(x^2 -2) +(x^2 -2) =0\\\\\implies (x^2 +1)(x^2 -2) = 0\\\\ \implies x^2 +1=0~~~~~~~~\text{or}~~~~~~~~~x^2 -2 = 0\\\\ \implies x = \pm\sqrt{-1}~~~~~~~\text{or}~~~~~~~~~~ x = \pm\sqrt 2\\\\\implies x= \pm i~~~~~~~~~~~~~\text{or}~~~~~~~~~ x= \pm\sqrt 2$

How many solutions for linear equation 3x + 5y = 25 can be found so that −20 < y < 10, and x is an integer?

ch4aika [34]

Answer:

Step-by-step explanation:

3x = 25 - 5y

-100 < 5y < 50

-50 < -5y < 100

-25 < 25 - 5y < 125

-8.333 < x < 41.667

41+8+1 = 50
