A TV has a listed price of $711.95 before tax. If the sales tax rate is 8.75%, find the total cost of the TV with sales tax
included.
Round your answer to the nearest cent, as necessary.
HELP I WILL MARK BRAINLIEST JUST PLEASE
Answer:
774.25
Step-by-step explanation:
8.75 becomes .0875 because it is 8.75%/100%
711.95 x .0875 = 62.295625
add the cost (711.95) and the tax (62.295625)
711.95 + 62.295625 = 774.245625
rounded = 774.25

angle APD would suggest that P is the vertex (where the rays of the angle originate) and A and D would be the rays that extend outward from the vertex forming an angle. This angle is not marked on the diagram.
Write the Quadratic Formula for the quadratic equation.
Answer:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
Step-by-step explanation:
Hello!
Let's start with the given equation and work our way towards x.
Solve for x[tex]ax^2 + bx + c = 0[/tex]Divide both sides by a
[tex]a(x^2 + \frac bax + \frac ca) = 0[/tex] [tex]x^2 + \frac bax + \frac ca = 0[/tex]Move c/a to the other side
[tex]x^2 + \frac bax = -\frac ca[/tex]At the step, we have to use the Completing the Square method.
[tex]x^2 + \frac bax + (\frac{b}{2a})^2 = -\frac ca + (\frac b{2a})^2[/tex][tex]x^2 + \frac bax + \frac{b^2}{4a^2} = -\frac ca + \frac {b^2}{4a^2}[/tex][tex](x + \frac b{2a})^2= -\frac ca + \frac{b^2}{4a^2}[/tex]Multiply -c/a by 4a and add the two fractions
[tex](x + \frac b{2a})^2= \frac{b^2 - 4ac}{4a^2}[/tex]Square Root both sides
[tex]\sqrt{(x + \frac b{2a})^2}= \sqrt{\frac{b^2 - 4ac}{4a^2}}[/tex][tex]x + \frac b{2a} = \pm\frac{\sqrt{b^2 - 4ac}}{2a}}[/tex]Subtract b/2a
[tex]x = \pm \frac{ \sqrt{b^2 - 4ac}}{2a} - \frac b{2a}[/tex][tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]And that's the derivation of the Quadratic Formula.
think about the ratio of circles and stars . Of the 8 circles,how many stars would there be?
Answer:
12
Step-by-step explanation:
There are 4 circles, 6 stars. The ratio is 4/6 = 2/3
if there is 8 circles in order to get the same ratio 8/x = 2/3 => x = 12
Write an
explicit formula for
an,
the nth
term of the sequence 39, 41, 43, ....
Answer:
2n + 37.
Step-by-step explanation:
an = a1 + d(n - 1)
Here a1 = 39 and d = 2
an = 39 + 2(n - 1)
= 39 + 2n - 2
= 2n + 37.

is -4.5 greater or less than 3?
Is -12/5 greater or less than 2?
From least to greatest order these: -3/2, -1, 11/4, 2, -3, 5.2, 0, 5.
(Btw I’m sorta new here so I apologize if I mess up)
Answer:
-4.5 is less than 3
-12/5 is less than 2
-3, -1.5, -1, 0, 2, 2.75, 5, 5.2
-3/2 = -1.5
11/4 = 2.75
Mark think of a number mark doubles it and add 2.9 to get answer of 30.6 form an equation with x from the information
Answer:
2x + 2.9 = 30.6
Step-by-step explanation:
We are to represent the unknown number that Mark thinks of with x
If Mark doubles this unknown number, he multiplies it by 2 and the unknown number becomes - 2x
He then adds 2.9
The equation becomes 2x + 2.9
The answer of the above equation is 30.6
This gives : 2x + 2.9 = 30.6

The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.
Answer:
x = 348
Step-by-step explanation:
The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.
0.15x + 65 + 0.1x + 28 = 180
0.25x + 93 = 180
0.25x = 180 - 93
0.25x = 87
x = 87/0.25
x = 348

$750 at 6% for 18 months
Answer:
The interest is $1242.734 and the amount is $13242.734.
Step-by-step explanation:
STEP 1: Convert interest rate of 1.5% per month into rate per year.
STEP 2: Convert 210 days into years.
STEP 3: Find an interest by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example P = $12000, i = 18% and t = 0.57534 years, so
STEP 4: Find an amount by using the formula .
Since P = $12000 and I = $1242.734 we have

Answer:
C. 244°Step-by-step explanation:
Angle formed by two tangents is equal to half of the difference of intercepted arcs:
m∠C = 1/2(arcAXB - arcAB)64° = 1/2(mAXB - mAB)mAXB - mAB = 128°The sum of the same two arcs is a full circle:
mAXB + mAB = 360°Add the two equations together:
2mAXB = 360° + 128°2mAXB = 488°mAXB = 244°Correct choice is C
Priscilla can make 2 bracelets in 16 minutes. At this rate, how many bracelets can she make in 64 minutes?
Answer:
8 bracelets.
Step-by-step explanation:
First, find out how long it'll take Priscilla to make on bracelet. It is given that she can make 2 bracelets in 16 minutes. Divide 16 with 2:
16/2 =8
Priscilla takes 8 minutes to make 1 bracelet. Divide 64 with 8 to find the amount of bracelets Priscila can make:
64/8 = 8
8 bracelets is your answer.
~
Given: Priscilla makes 2 bracelets in 16 minutes
To Attain: How many Bracelets she will make in 64 minutes?
⠀⠀⠀⠀⠀⠀__________________
Solution:
Firstly, We will divide the 16min with 2 to find the that how many time taken to make 1 bracelets. then we will multiply the rate with 64min to find how many bracelets she will make! Let's do it•
⠀⠀
[tex]:\implies\sf\dfrac{\cancel{16}^{8}}{\cancel{2_1}}[/tex]
⠀⠀
It will take 8 minutes to make one Bracelets.
⠀⠀
So, Let's find out that how many bracelets she will make in 64 minutes
⠀⠀
[tex]:\implies\sf\dfrac{\cancel{64}^{8}}{\cancel{8_1}}[/tex]
⠀⠀
[tex]\therefore \underline {\sf{Hence , \:She \: will \: make \: \pmb{8 \: bracelets }\: in \: 64 \: minutes. }}[/tex]
