Answer:
Step-by-step explanation:
Three local stores are each selling their videos game consoles for the same price the table below shows how many consoles have been sold at each of the stores and the total sales dollars for the consoles.
Applying proportions, it is found that the discounted price of each console at store B is given by:
B. $210.80.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, at store B, 15 consoles sold for a total of $3,720, hence the price per console is of:
P = 3720/15 = $248.
A discount of 15% is applied, which means that the new price is 85% of the original price, hence:
P = 0.85 x 248 = $210.8.
Which means that option B is correct.

Answer:
[tex]\tan(X)=\dfrac{77}{36}[/tex]
Step-by-step explanation:
First we need to find the length of side WX.
To do this, use Pythagoras' Theorem: [tex]a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
[tex]\implies WX^2+77^2=85^2[/tex]
[tex]\implies WX^2=85^2-77^2[/tex]
[tex]\implies WX=\sqrt{85^2-77^2}[/tex]
[tex]\implies WX=36[/tex]
Now use the Tan trig ratio:
[tex]\tan(x)=\sf \dfrac{O}{A}[/tex]
where:
[tex]x[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleFrom inspection of the triangle,
[tex]x[/tex] = ∠XO = 77A = WX = 36Substituting these values into the tan trig formula:
[tex]\implies \tan(X)=\dfrac{77}{36}[/tex]
Therefore, the tangent of ∠X is [tex]\dfrac{77}{36}[/tex]
Answer:
77 / 36
Step-by-step explanation:
Finding the adjacent side
WX² = VX² - VW² [Pythagorean Theorem]WX² = (85)² - (77)²WX² = 7225 - 2929WX = √1296WX = 36Tangent of ∠X
Opposite side / Adjacent sideWX / VW77 / 366 x 5/8 in simplest form

Que → The hieght of The statue of Liberty is 93m. This is about 27% of the Hancove building in Chicago. What is approximate Hieght of Hancove Building?
Answer → Let height of Hancove Building be H.
Now according to question, 27% of H = 93m
27 / 100 (H) = 93m
H = 93 x 100 ÷ 27
H = 344.44m
Therefore, the approximate Hieght of Hancove Building is around 344.4m
Answer:
344.44 mStep-by-step explanation:
Let the missing height is h.
We have 93 m is 27% of h, need to find the value of h
27% of h is 0.27h, the equation we need is below
0.27h = 93h = 93/0.27h = 344.44which expression entered into a graphing calculator will return the probability that a data value in a normal distribution is between a z score of -1.99 and a z score of 0.18
The expression that returns the probability that a data value in a normal distribution is between a z- score of -0.18 and a z-score of 1.99 is (d) normalcdf(-0.18, 1.99)
How to determine the expression?To calculate the probability between two z-scores is to calculate the area between the z-scores.
This is done using the following syntax:
normalcdf(lower bound, upper bound)
From the question, the lower and the upper z-scores are -0.18 and 1.99
So, the formula would be normalcdf(-0.18, 1.99)
Hence, the expression is (d)

Each month Edward budgets $1860 for fixed expenses, $860 for living expenses, and $259 for annual expenses. His annual net income is $32,508. Which statement best describes his monthly budget?
It shows a deficit of $180
It shows a surplus of $261
It shows a deficit of $261
It is balanced
SHOW WORK PLLZ
(Will give brainiest)
Answer:
It shows a deficit of $261
Step-by-step explanation:
$32,508/12 = $2709 per month
$2709 - ($1860 + $860 + $259) = -$270
I'm assuming you put a typo somewhere, but the closest answer is the deficit of $261
Building A is 200 feet shorter than Building B. The total height of the two buildings is 1530 feet. Find the height of each building.
Answer:
B Building = 865 feet, A Building = 665 feet.
Step-by-step explanation:
If you divide 1530 by 2 you get 765, if you add 100 to 765, and subtract 100 from 865, there is a 200 feet difference from each of the buildings.

Given that

its curl is
[tex]\displaystyle \nabla\times\vec A = \left(\frac{\partial\left(2yz^4\right)}{\partial y} - \frac{\partial\left(-2x^2y\right)}{\partial z}\right) \, \vec\imath - \left(\frac{\partial\left(2yz^4\right)}{\partial x} - \frac{\partial\left(xz^3\right)}{\partial z}\right) \, \vec\jmath \\ ~~~~~~~~~~~~ + \left(\frac{\partial\left(-2x^2y\right)}{\partial x} - \frac{\partial\left(xz^3\right)}{\partial y}\right) \, \vec k[/tex]

-4+x=10 is 13 the solution
Answer:
No.
Step-by-step explanation:
You are trying to solve for x. Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides of the equation to isolate the variable, x:
-4 + x = 10
-4 (+4) + x = 10 (+4)
x = 10 +4
x = 14
x = 14, x ≠ 13, ∴ 13 is not a solution.

PLEASE MARK ME BRAINLIESTPlease answer urgent!
Reason:
Triangles A, B and E all have the angles 68 and 79 with a 3 unit side sandwiched between them. We can use the angle side angle (ASA) congruence theorem to prove those three triangles are identical copies of each other. They are rotated, reflected and shifted versions of one another. These tranformations are known as rigid transformations or isometries.
On the other hand, we can rule out choice C because the side between the angles is not 3 units long (even though the angles do match up). The same goes for choice D.
