lets see how much will cost 3 pens
3*.43=1.29
booklets
1.85*4=7.4
total
7.40+1.29=8.69
10-8.69=1.31
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]
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)

Which math expression means "the sum of 270 and 180"?
Answer:
A
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Sum means to add so answer A is correct
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)

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 −∞ ).

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

Given: \overline{BD} \cong \overline{BE}, BD ≅ BE , \overline{DE} DE bisects \overline{AB} AB and \overline{DE} DE bisects \overline{BC}. BC . Prove: \overline{AB} \cong \overline{BC} AB ≅ BC .
Given:
[tex]\overline{BD} \cong \overline{BE}[/tex]
DE bisects [tex]\overline{AB}[/tex].
DE bisects [tex]\overline{BC}[/tex].
To prove:
[tex]\overline{AB} \cong \overline{BC}[/tex]
Proof:
DE bisects [tex]\overline{AB}[/tex]
Then, [tex]AD=BD[/tex]. ...(i)
DE bisects [tex]\overline{BC}[/tex].
Then, [tex]BE=CE[/tex]. ...(ii)
We have,
[tex]\overline{BD} \cong \overline{BE}[/tex] ...(iii)
Using (i), (ii) and (iii), we get
[tex]\overline{AD} \cong \overline{CE}[/tex] ...(iv)
Adding (iii) and (iv), we get
[tex]\overline{BD}+\overline{AD} \cong \overline{BE}+\overline{CE}[/tex]
[tex]\overline{AB} \cong \overline{BC}[/tex]
Hence proved.
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

Step-by-step explanation:
We know there can only be up to 2 solutions for a quadratic equation.
5x^2-2x-9=0 is your equation, make sure to move that 1 to the left
Now we can use the quadratic formula
a=5
b= -2
c= -9
x= −1.15647
x=1.55647
Thus I would select the last 2 boxes. Both of them are solutions.

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

8. What is the annual salary for someone who earns a biweekly salary
of $863.00?
Answer:
approximately $22438
Explanation:
If this is wrong which im pretty sure it isnt, im sorry :)
Answer: Annual Salary = $22,438
===================================================
Work Shown:
biweekly means every 2 weeks
There are roughly 52 weeks in a year, so there are 52/2 = 26 biweekly paychecks over the course of the full year.
So the annual salary is 26*863.00 = 22,438 dollars.
Choose the method of pay that would result in the most earnings for one month on sales of $40,000. a. Straight commission of 7.5% on all sales. b. Monthly salary of $1,600 plus 2.5% commission on all sales. c. Graduated commission of 5% on the first $30,000 in sales and 6% on anything over that. d. Graduated commission of 4% on the first $25,000 in sales and 8% on anything over that. Please select the best answer from the choices provided A B C D
Answer:
The answer is "Option a".
Step-by-step explanation:
In the question, the answer is 7.5% straight on all revenue because the commission would be a charge the corporation pays to something like a sales representative to help or achieve a sale in return for their services.

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]

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.

What is the image of the point (6,7) after a rotation of 90 degrees counterclockwise about the origin
Answer: Note the location of Point C’, the image of Point C after a 90-degree rotation. And this process could be repeated if you wanted to rotation Point C 180 degrees or 270 degrees counterclockwise: Point C after a 180-degree rotatio.
Hope it helps
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).
