Answer:
$30
Step-by-step explanation:
If $25 is 100%,
$2.5 is 10%
$0.25 is 1%
$3.75 is 15%
$0.75 is 3%
Then add $25, $3.75 and 0.75 which is also equivalent to 100%+15%+3%=29.5 and if you rounded it up to the nearest cent it is 30

Answer:
[tex]8x^2 + 18x + 36[/tex]
Step-by-step explanation:
I did it on paper.
Answer:
A.) 8x^2 + 18x + 36
Step-by-step explanation:
Use these steps to see how exactly I arrived at my answer!
[tex]=8x^3+2x^2-72\\=2\cdot \:4x^3+2x^2-2\cdot \:36\\=2\left(4x^3+x^2-36\right)\\[/tex]
[tex]=4x^3+x^2-36\\=\left(x-2\right)\frac{4x^3+x^2-36}{x-2}\\=4x^2+\frac{9x^2-36}{x-2}\\=4x^2+9x+\frac{18x-36}{x-2}\\=4x^2+9x+18[/tex]
[tex]=2\left(x-2\right)\left(4x^2+9x+18\right)\\=\frac{2\left(x-2\right)\left(4x^2+9x+18\right)}{x-2}[/tex]
Between these steps, I canceled out a common factor!
[tex]=2\left(4x^2+9x+18\right)\\= 8x^2+18x+36[/tex]
A drawer contain pens , 14 blue pens and 8 black pens , 14 silver paper clips , and 16 white paper clips . If you randomly select a pen and paper clip from the drawer , what is the probability that you select a red pen and white paper clip
Step-by-step explanation:
Total pens = 22
Total clips = 30
Probability of red pen = 0
Because there are no red pens
Probability of white clip = 16/30 = 8/15
In a certain isosceles triangle, the base is 1 1/2 times as long as each leg and the perimeter is 63. How long is the base?
Answer:
The base is 27 units long.
Step-by-step explanation:
This is a solve the system question. Call the length of the base B and the length of each leg L. We are told:
[tex]B=1.5L[/tex]
and
[tex]B+2L=63[/tex]
Sub the first equation into the second:
[tex]1.5L+2L=63\\3.5L=63\\L=18[/tex]
Now that we have the leg length, sub that into either of the original equations to find the base. I'll use the first equation:
[tex]B=1.5(18)\\B=27[/tex]

Which functions have the same rate of change?
y=0.3x-6
y=3x-8
y=0.3x+4
y=0.03x+1
1:A and D
2:B and C
3:A and C
4:C and D
Answer:
Option 3
Step-by-step explanation:
All equations are in slope-intercept form. [tex]y=mx+b[/tex]
The 'm' is the slope.
The 'b' is the y-intercept.
The slope is also known as the rate of change. So, we would have to look at what replaces 'm' and select two equations that have the same rate of change.
Let's look over the equations:
Equation A:[tex]y=0.3x-6[/tex]
In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.
Equation B:[tex]y=3x-8[/tex]
In this equation, 3 replaces 'm', so the rate of change for this equation is 3.
Equation C:[tex]y=0.3x+4[/tex]In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.
Equation D:[tex]y=0.03x+1[/tex]In this equation, 0.03 replaces 'm', so the rate of change for this equation is 0.03.
Equation C and equation A have 0.3 as the slope. Since the question asks for two equations that have the same rate of change, the answer would be Equations A and C, or Option 3.

Tom has to take three medicines each day. One is to be taken
every 3 hours, one every 4 hours and one just four times a day.
He takes his first dose on Monday at 9am, what is the next time he
takes all three medicines together?
Please help
Answer:
9pm Monday
Step-by-step explanation:
It would take 12 hours, that would be when all of the medicines would be taken at the same time, because 3/4/6 are factors of 12
Answer:
Monday at 9pm
Step-by-step explanation:
The first drug is by every 9,12,3,and 6.The second drug is by every 9,1,and 5.While the third drug is by every 9 and 3.Therefore, 9 is common so the next time the drugs will be taken at the same time is by 9pm.

A company is worth $79,600,000. Write this number in scientific notation.
79,600,000=
Answer:
The answer is 7.96×10⁷ .
Step-by-step explanation:
As the decimal moves to the left , you have to add one more power to the base 10 :
e.g
7 960 000.0 = 7 960 000×10¹
796 000.00 = 796 000×10²
79 600.000 = 79 600×10³
7 960.0000 = 7 960×10⁴
796.00000 = 796×10⁵
79.600000 = 79.6×10⁶
7.9600000 = 7.96×10⁷

Define dot product, inner product, cross product.
Answer:
Dot product. ... In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used and often called "the" inner product (or rarely projection product) of Euclidean space even though it is not the only inner product that can be defined on Euclidean space; see also inner product space.
Step-by-step explanation:
Answer:
- A dot product is the product of the magnitude of the vectors and the cos of the angle between them.
- A cross product is the product of the magnitude of the vectors and the sine of the angle that they subtend on each other.
- An inner product is a generalization of the dot product.
Step-by-step explanation:
Dot product - the sum of the products of the corresponding entries of the two sequences of numbers. Geometrically, it is the product of the Euclidean magnitudes of the two vectors and the cosine of the angle between them. These definitions are equivalent when using Cartesian coordinates.
Cross Product - The cross product is a mathematical operation which can be done between two three-dimensional vectors. It is often represented by the symbol. After performing the cross product, a new vector is formed. The cross product of two vectors is always perpendicular to both of the vectors which were "crossed".
Inner product - In a vector space, it is a way to multiply vectors together, with the result of this multiplication being a scalar.

Morgan has 5 blue t-shirts , 3 green t-shirts and 2 red t-shirts . She randomly picks a shirt. What is the probability of choosing each color?
Answer:
Confusing question but I think it's 10:10
Step-by-step explanation:
Total outcome = 5:3:2
= 5+3+2
=10.
Probability = number of success
Total outcome
= 10/10
Therefore the probability of Morgan choosing each colour is 10:10.
Select a setting so that each given point will lie within the viewing window.
(-13,3), (0,0).(-2,-7)
Answer:
The given points are
[tex](-13,3)\\(0,0)\\(-2,-7)[/tex]
The setting would have a interval or 2 units above and below the minimum and maximum of each coordinate.
The given maxium horizontal coordinate is 0.
The given minimum horizontal coordinate is -13.
The given maximum vertical coordinate is 3.
The given minimum vertical coordinate is -7.
Now, we extend each maximum and minimum value by 2 units to create the setting.
So, the setting is
[tex]x_{min}=-15\\x_{max}=2\\ y_{min}=-9\\y_{max}=5[/tex]
With a scale of 2 units.
