9. Jeremy receives a base salary of $25,000 plus 5% commission on his sales. Jeremy received a total salary of
$45,000 last year. How much were his total sales?
a. $20,000
b. $70,000
c. $400,000
d $900,000
Answer:
c. $400,000
Step-by-step explanation:
Let his total sales be $x.
Salary + commission =$45000
[tex] \therefore \: 25000 + 5 \% \: of \: x = 45000 \\ \\ \frac{5}{100} x = 45000 - 25000 \\ \\ \frac{1}{20}x = 20000 \\ \\ x = 20 \times 20000 \\ \\ x = \$\:400, 000[/tex]
Prove This :
sin(A+B)+sin(A−B)=2sinA⋅cosB
Answer:
We know
sin (A + B) = sin A cos B + cos A sin B
sin (A - B) = sin A cos B - cos A sin B
(A + B) + sin (A - B)
= sin A cos B + cos A sin B + sin A cos B - cos A sin B
= sin A cos B + sin A cos B
= 2 sin A cos B

Help me please !!!!!!
Answer:
z = -44
Step-by-step explanation:
3/4 (x - 8) = 4
3(x - 8) = 16
3x - 24 = 16
3x = 40
x = 40/3
4 - 2x = -5x - z
4 = -3x - z
z = -3x - 4
z = -3(40/3) - 4
z = -40 - 4
z = -44
Answer:
Z=-44
Step-by-step explanation:
To figure out z. we have to figure out x first
So
3/4(x-8)=4
x-8=4÷3/4
x-8=4×4/3
x-8=16/3
3x-24=16
3x=16+24
3x=40
x=40/3
Now
4-2(40/3)=-5(40/3)-z
4-80/3=-200/3-z
z-68/3=-200/3
z=-200/3+68/3
z=-44
Drake is considering buying one of the four popular e-readers where the e-reader's premium services is a monthly charge. The functions LaTeX: A_1\left(t\right)=\:5t+350,\:\:\:A_2\left(t\right)=10t+250,\:\:\:\:\:A_3\left(t\right)=499,\:and\:\:\:\:\:\:A_4\left(t\right)=15t+179A 1 ( t ) = 5 t + 350 , A 2 ( t ) = 10 t + 250 , A 3 ( t ) = 499 , a n d A 4 ( t ) = 15 t + 179 model the total amount of money A, in dollars, that Drake spends after buying the e-reader and subscribing to t months of the e-reader's premium services. Which e-reader has the greatest monthly subscription cost?
Answer:
[tex]A_4[/tex]
Step-by-step explanation:
The cost of the e-readers and the subscription of their services are
[tex]A_1(t)=5t+350[/tex]
[tex]A_2(t)=10t+250[/tex]
[tex]A_3(t)=499[/tex]
[tex]A_4(t)=15t+179[/tex]
The functions are of the form
[tex]A(t)=mt+c[/tex]
Where [tex]m[/tex] is the monthly subscription cost and [tex]c[/tex] is the cost of the e-reader.
So, 15 dollars is the highest subscription cost which is of the 4th e-reader.
Hence [tex]A_4[/tex] has the highest subscription cost.
The value of y is directly proportional to the value of x. If y = 15 when x = 90, what is the value x when y = 45?
Answer:
y = 45 x = 120
Step-by-step explanation:
90 - 15 = 75
45 + 75 = 120

determine the value of x.
Answer: 1) -5.8
Step-by-step explanation:
in order to solve the problem you have to put it together:
9x-5 = 14x+24
then go from there : subtract 24 on both sides , then subtract 9x on both sides , that’ll leave you with : -29 = 5x
so from there we divide , giving us x= -5.8

If Tony earns five dollars on Monday and five dollars on Tuesday is that a sum of zero? need help I’m in 4th
Answer:
The sum is $10
Step-by-step explanation:
Since Tony got $5 on Monday and $5 on Tuesday, we can add them together by doing 5+5. We can add 5 and 5 together to get a total of $10 that Tony has earned. This means that it isn't a sum of 0 but a sum of 10.

3x-2y= 12
Linear Functions, please help, it’s on a test, and I’m about to fail this whole grade, thank you
Answer:
Slope: 3/2
y intercept (0,-6)
Step-by-step explanation:
3x-2y=12
First, solve for y
2y=12-3x
divide each term by -2 and simplify
y=-6+[tex]\frac{3x}{2}[/tex] or y=[tex]\frac{3}{2}[/tex]x-6
Slope intercept form: y=mx+b
therefor m =[tex]\frac{3}{2}[/tex] and y (0,-6)
Find the value of x and the measure of each angle in the parallelogram
Answer:
[tex]\angle D= 162\\\\\angle E = 18\\\\\angle F = 162\\\\\angle G = 18[/tex]
Step-by-step explanation:
By properties of parallelograms we know that opposite are the same so we have
[tex]12x=4(x+3)\\\\4(3x)=4(x+3)\\\\3x=x+3\\\\2x=3\\\\x=\frac{3}{2}[/tex]
so for the angles we have
[tex]\angle G=\angle E=12(\frac{3}{2})=18\\\\\angle D=\angle F = 180-\angle G=180-18=162[/tex]

Consider p(x)=3x^3+ax+5a, a is an element of the integers.
The polynomial p(x) leaves a remainder of -7 when divided by (x-a). Show that only one value of a satisfies the above condition and state it’s value.
By the remainder theorem,
p(a) = 3a³ + a² + 5a = -7
so that
3a³ + a² + 5a + 7 = 0
Since you know a is an integer, you can try to factorize this, or use the rational root theorem to generate a list of potential rational roots, and from there you'd select the integer roots. The rational ones are of the form m/n, where m divides the constant term 7 and n divides the leading coefficient 3. They are
a = ± 1 or ± 1/3 or ± 7 or ±7/3
so there are 4 integer candidates,
a = -1 or 1 or -7 or 7
Check the value of f(a) = 3a³ + a² + 5a + 7 at each of these:
a = -1 → f(a) = 0
a = 1 → f(a) = 16
a = -7 → f(a) = -1008
a = 7 → f(a) = 1120
and only a = -1 is a root of 3a³ + a² + 5a + 7, so that's your answer. In fact,
3a³ + a² + 5a + 7 = (a + 1) (3a² - 2a + 7)

The new coordinates after rotation will be (-7, 6).
What is mean by Rotation of a Point in X - Y plane?A rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point.
We have to given that;
A Point on a xy - plane as (6, 7) which is rotated by 90° counter clockwise about the origin.
Now, According to the question, we have;
A point with coordinates = (6, 7)
We know that, Any point (say A[x, y]) when rotated 90° counter clockwise about the origin, then its new coordinates become A'(-y, x).
Hence, By Using this rule, the coordinates of the point after rotation of point by 90° counter clockwise about the origin will be;
⇒ (-7, 6).
Hence, The new coordinates = (-7, 6).

How does the sketch of a graph of function help describe its behavior
Answer:
The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).

Mr. and Mrs. Preston and their two children are very excited about their upcoming
vacation. The Preston family is leaving early in the morning to drive to Florida. It will take
two days to drive to Florida. The family will have to stay one night in a hotel. Mr. and
Mrs. Preston want to spend as little money as possible for the hotel room. Mr. Preston
uses the information below and rounding to estimate which hotel offers the best deal.
Which hotel offers the best deal for the Preston family to stay? Show all your
Answer:
They will spend less at the sunny side hotel
Step-by-step explanation:
The attachment completes the question.
From the question, we understand that there are 4 individuals involved.
Mr. Preston (1)Mrs. Preston (1)The children (2)And they will spend one night
First, we need to calculate the expenses in Traveler's hotel.
[tex]Rate = \$107.10[/tex] (for 3 people)
[tex]Additional\ Person = \$21.55[/tex] (for 1 person)
[tex]Breakfast = \$8.75 * 4[/tex] (for 4 people)
[tex]Tax = \$16.85[/tex]
Total Expenses
[tex]Total = \$107.10 + \$21.55 + \$8.75* 4 + \$16.85[/tex]
[tex]Total = \$107.10 + \$21.55 + \$35.00 + \$16.85[/tex]
[tex]Total = \$108.50[/tex]
For Sunny Side hotel:
[tex]Rate = \$152.95[/tex] (for 4 people)
[tex]Tax = \$21.34[/tex]
Total Expenses:
[tex]Total = \$152.95 + \$21.34[/tex]
[tex]Total = \$174.29[/tex]
By comparison, they will spend less at the sunny side hotel.
find the value of x and y
x° + 2y° = 180° ⇒ 2y° = 180° - x°
x° = 60° {three sides of the same lengh, means three angles=60°}
2y° = 180° - 60°
2y° = 120°
y° = 60°
