Answer:
$94.314
Step-by-step explanation:
Given data
Commission = 12%
Sale= $785.95
Let us find 12% of $785.95
=12/100* 785.95
=0.12* 785.95
=$94.314
Hence she earns $94.314
A bag contains 4 red marbles, 3 blue marbles and 2 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that both marbles drawn will be red?
Answer:
Probability = 16.7
Step-by-step explanation:
Total marbles 9
Choosing 2 red = [tex]4C_2[/tex]
Choosing 2 marbles from 9 marbles = [tex]9C_2[/tex]
Probability percent of choosing 2 red marbles from 9 marbles
[tex]\frac{4C_2}{9C_2} = \frac{1}{6} \times 100 = 0.1667 \times 100 = 16.7[/tex]
Answer:
16.6
Step-by-step explanation:
4+3+2=9 marbles
4=red
4/9*3/8=1/6
1/6= 16.6

This is required inequality.
Do the side lengths 15,20 and 25 form a right triangle?
PLEASEEEE HELPPPP!!! asap
===================================================
Work Shown:
a^2+b^2 = c^2
15^2+20^2 = 25^2
225+400 = 625
625 = 625
Since the last equation is true, this makes the first equation true for those a,b,c values. Therefore, by the pythagorean theorem converse, this is a right triangle.
Side note: c is always the longest side.

For f(x) = 3x + 1 and g(x) = x ^ 2 - 6 find (8/f)(x)
Answer:
9x² + 6x - 5
Step-by-step explanation:
If you mean g(f(x))
g(x) = x² - 6
f(x) = 3x + 1
Then, g(f(x)) = g(3x + 1)
but g(x) = x² - 6
g(3x + 1) = (3x + 1)² - 6 = 9x² + 6x + 1 - 6
= 9x² + 6x - 5
Angelica reads 15 pages of a book each day. In 10 days, she reads 200 pages. Assume the relationship is linear. Find and interpret the rate of change and initial value.
help me please
Given:
Angelica reads 15 pages of a book each day.
In 10 days, she reads 200 pages.
Assume the relationship is linear.
To find:
The rate of change and initial value.
Solution:
The slope intercept form of a linear function is:
[tex]y=mx+b[/tex] ...(i)
Where m is the slope and b is the y-intercept.
Angelica reads 15 pages of a book each day. So, the rate of change is 15 pages per day and [tex]m=15[/tex].
In 10 days, she reads 200 pages. It means the linear relation passes through the point (10,200).
Putting [tex]x=10,y=200,m=15[/tex] in (i), we get
[tex]200=15(10)+b[/tex]
[tex]200=150+b[/tex]
[tex]200-150=b[/tex]
[tex]50=b[/tex]
So, the y-intercept is 50. It means the initial number of pages angelica already read is 50.
Therefore, the rate of change is 15, it means Angelica reads 15 pages per day. The y-intercept is 50, it means the initial number of pages angelica already read is 50.
The angle of elevation to a nearby tree from a point on the ground is measured to be 45^{\circ} ∘ . How tall is the tree if the point on the ground is 79 feet from the tree? Round your answer to the nearest hundredth of a foot if necessary.
Answer: 79 ft
Step-by-step explanation:
Given
The angle of elevation is [tex]45^{\circ}[/tex]
Distance of the point from the tree is [tex]79\ ft[/tex]
Suppose h is the height of the tree.
[tex]\Rightarrow \dfrac{h}{79}=\tan 45^{\circ}\\\\\Rightarrow h=79\tan 45^{\circ}\quad [\tan 45^{\circ}=1]\\\Rightarrow h=79\ ft[/tex]
Thus, the height of the tree is 79 ft

An estate valued at $90 000 is divided among three daughters, Karen, Kaylia and Keisha in the ratio 5 : 8 : 2 respectively. Calculate the amount each daughter receives
Answer:
Kaylia = $48,000
Kaylia = $48,000
Keisha = $12,000
Step-by-step explanation:
Karen = 5
Kaylia = 8
Keisha = 2
Total ratio = 5 + 8 + 2
= 15
Estate value = $90 000
Karen = 5/15 × $90 000
= 1/3 × $90 000
= $90 000 / 3
= $30,000
Karen = $30,000
Kaylia = 8/15 × $90,000
= (8 * 90,000) / 15
= 720,000/15
= $48,000
Kaylia = $48,000
Keisha = 2/15 × $90,000
= 180,000/15
= $12,000
Keisha = $12,000
in the given graph of a cubic polynomial, what are the number of real zeros and complex zeros respectively
Answer:
1 real and 2 complex
Step-by-step explanation:
The Fundamental theorem of Algebra states that a polynomial of degree n has n zeros, some may be complex.
A cubic is a polynomial of degree 3 , then has 3 zeros.
From the graph
There is a real zero at x = 4
Thus the other 2 must be complex

An NBA basketball court is rectangular in shape where the length is 2m less than twice the width. If the perimeter of the court is 86m, what are the dimensions (length and width) of the court?
Answer:
Length = 28 m
Width = 15 m
Step-by-step explanation:
Court is rectangular in shape.
Now, we are told that;
Length is 2m less than twice the width(W) .
Thus;
Length; L = 2W - 2
We are told the perimeter is 86 m.
Formula for perimeter of a rectangle is;
P = 2(L + W)
Thus;
2((2W - 2) + W) = 86
Divide both sides by 2 to get;
(2W - 2) + W = 43
3W - 2 = 43
3W = 43 + 2
3W = 45
W = 45/3
W = 15 m
Thus; L = 2(15) - 2
L = 30 - 2
L = 28 m

Answer:
first u will find de L.C.M which is 6
so u will multiply de whole equation by 6 hence
6(x/3)- 6(x-1/ 2) greater or equal to 6(1)
u will then cancel getting de equation to be
2(x)-3(x-1) greater or equal to 6 (1)
now, u will expand de equation
2x-3x+3 greater or equal to 6
now u group like terms
2x-3x greater or equal to 6-3
hint: greater or equal to must be done with it's symbol
so now for de answer, u will get -x greater or equal to 3
wen u get this, u change de operation to be opposite of de current sign
now de final answer becomes
-x less or equal to 3Which table shows a proportional relationship between x and y?
What term describes the process of using the output of one function as the input for another? A. Function mapping B. Function simplification C. Function composition D. Function notation
Answer: C. Function composition
Step-by-step explanation:
If we have two functions, we can form a new function by composing one function into the other. Such functions are known as composite functions.
For example we have two functions f and g and produces a function h such that h(x) = g(f(x)).
It is generally a function that is written inside another function.
i.e. it is a process of using the output of one function as the input for another.
Thus, the correct option is C.
The required term: Function composition

if log w = (1/2) log x + log y, then w= ?
Answer:
[tex]w = \sqrt{x} y[/tex]
Step-by-step explanation:
Formula used :
[tex]a \ log\ b = log \ b^a\\\\log a + log b = log \ ab[/tex]
[tex]log\ w = \frac{1}{2} log\ x + log \ y\\\\log \ w = log \sqrt{x} + log \ y\\\\log \ w = log \sqrt{x} y\\\\w = \sqrt{x} y[/tex]

Which statement best describes how to determine whether f(x) = x² – X + 8 is an even function?
1. Determine whether -x²-(-x)+8 is equivalent to x²-x+8
2. Determine whether (x)²-x+8 is equivalent to x²-x+8
3. Determine whether -x²(-x)+8 is equivalent to -(x²-x+8)
4. Determine whether (-2)²-(-x)+8 is equivalent to -(x²-x+8)
Answer:
Option 1
Step-by-step explanation:
You can tell if a function is even if [tex]f(-x)=f(x)[/tex]:
[tex]f(x)=x^2-x+8[/tex]
[tex]f(-x)=(-x)^2-(-x)+8[/tex]
[tex]f(-x)=x^2+x+8[/tex]
Since [tex]f(-x)\neq f(x)[/tex], the function is not even. Therefore, option 1 is the best option.
