Brenda has 5/6 of a pie to divide evenly among 4 people. How much pie will each person get?

Answer:

0.153

Step-by-step explanation:

It has been a long time since I've done this, so I hope it is correct:

cos = adjacent side / hypotenuse

cos x = 13 / 85 = 0.153

The decimal value of cos X can be found using a calculator or trigonometric table. Cosine is a trigonometric function that gives the ratio of the length of the adjacent side to the hypotenuse of a right triangle.

The decimal value of cos X can be found using a calculator or trigonometric table. Cosine is a trigonometric function that gives the ratio of the length of the adjacent side to the hypotenuse of a right triangle.

Answer:

C' = (-5, -2)

Step-by-step explanation:

Reflection over the y-axis negates the x-coordinate.

C(5, -2) ⇒ C'(-5, -2)

Answer:

The correct option is 3.

Step-by-step explanation:

The vertices of isosceles trapezoid ABCD are A(2, 0), B(4, 0), C(5, -2), D(1, -2).

If a figure reflected over the y-axis, then the relation between coordinates of preimage and image is defined as

[tex](x,y)\rightarrow (-x,y)[/tex]

It is given that ABCD reflected over the y-axis and coordinates of point C are (5,-2), so the coordinates of C' are

[tex]C(5,-2)\rightarrow C'(-5,-2)[/tex]

The coordinates of C' are(-5,-2). Therefore the correct option is 3.

Answer:

27 total child tickets sold

Step-by-step explanation:

Price of child ticket = $5.20

Price of adult admission = $8.80

Now according to given condition of the day of Monday

Let no of child tickets sold are = x

then

total no of adult tickets sold are =4 x

Total sales = $ 1090.80

Now according to given

we know that

sales of child tickets + sales of adults tickets = total sales

Putting in the values

x * (5.20) + (4x)*(8.80) = 1090.80

5.20 x + 35.2 x = 1090.80

40.4 x = 1090.80

Dividing both sides by 40.4

[tex]\frac{40.4x}{40.4}=\frac{1090.80}{40.4}[/tex]

x= 27

So total no of child tickets sold are 27

Answer: C) 5

--------------

x = independent variable, y = dependent variable

Assuming this is a linear function, each increase of x by 2 leads to y going up by 10. So 10/2 = 5 is the unit increase each time x bumps up by 1.

-------------------

An alternative is to use the slope formula to get

m = (y2 - y1)/(x2 - x1)

m = (25 - 15)/(4 - 2)

m = 10/2 <--- this expression shows up again

m = 5 <---- leading to the same answer as before

So we see that the slope formula is a more drawn out method to finding the answer.

It is easiest to check the offered answers. You can also solve this graphically, or by solving the simultaneous equations.

You can, for example, square the first equation and subtract the second:

... (x+y)² -(x²+y²) = 5² -25

... 2xy = 0

This will be true for x=0 or for y=0, so (0, 5) and (5, 0) are solutions to the pair of equations.

To find the solution set to the given system, substitute the value of x into the second equation, factor, and solve for y. The solution set is (5,0).

To find the solution set to the given system of equations, we can solve them simultaneously. From the first equation, we have x = 5 - y. Substituting this value of x into the second equation, we get (5 - y)^2 + y^2 = 25. Expanding and simplifying this equation gives us 2y^2 - 10y = 0. Factoring out y, we have y(2y - 10) = 0. So either y = 0 or 2y - 10 = 0. Solving the second equation for y, we get y = 5.

Therefore, the solution set to the system of equations is (5,0).

Answer:

The values for both of the missing sides is 8.

Step-by-step explanation:

The hypotenuse of a right triangle = a(square root of 2)

Therefore the other two missing sides equal a.

Therefore, the other two sides equal 8.

now, recalling the pythagorean theorem a little.

the hypotenuse here is 8√2, and then we have the other two sides, BUT, the opposite angle for each is actually the same 45°, if each opposite angle is the same, the length of the side on the other end is also the same.

so we have say side "b" and side "a", but because each has an opposite angle of 45°, that means "b" and "a" are actually twins.

[tex]\bf \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies (8\sqrt{2})^2=a^2+b^2 \qquad \begin{cases} c=\stackrel{hypotenuse}{8\sqrt{2}}\\ a=adjacent\\ b=opposite\\ \end{cases} \\\\\\ \stackrel{\textit{since we know that \underline{a = b}}}{[8^2(\sqrt{2})^2]=a^2+a^2}\implies 64(2)=2a^2\implies \cfrac{64(2)}{2}=a^2\implies 64=a^2 \\\\\\ \sqrt{64}=a\implies 8=a=b[/tex]

Answer:

96

Step-by-step explanation:

Let x represent the number of adult tickets sold. Then (182-x) is the number of child tickets sold. The total sales is then ...

... 6.60·(182 -x) +9.80·x = 1508.40

... 3.20x = 1508.40 -1201.20 . . . . . simplify, subtract 1201.20

... 307.20/3.20 = x = 96 . . . . . . . . divide by the coefficient of x

96 adult tickets were sold that day.

Final answer:

By setting up and solving a system of equations, it is determined that 96 adult tickets were sold at the movie theatre.

Explanation:

To solve the problem of how many adult tickets were sold at the movie theatre, we need to set up a system of equations based on the given information: child admission is $6.60, adult admission is $9.80, 182 tickets were sold in total, and the sales amounted to $1508.40.

Let's denote the number of child tickets sold as c and the number of adult tickets sold as a. We can then create the following two equations:

c + a = 182 (since the total number of tickets sold was 182)

6.60c + 9.80a = 1508.40 (representing the total sales from the tickets)

We can solve these equations using substitution or elimination methods. Here's the step-by-step solution using the elimination method:

First, we multiply the first equation by -6.60 to set up for elimination:

-6.60c - 6.60a = -1201.20

Now we add this to the second equation:

6.60c + 9.80a = 1508.40

3.20a = 307.20

Dividing both sides by 3.20 gives us a = 96.

Therefore, 96 adult tickets were sold that day.

Answer:

Step-by-step explanation:

The table that can be used to determine how long it would take if Elias and Niko polished the silver together is table B

You can create a table to determine the time it would take Elias and Niko together to polish the silver based on their individual rates of completing the task.

Let's denote:

Elias's rate of polishing = 1 job / 40 minutes

Niko's rate of polishing = 1 job / 50 minutes

To find the combined rate when they work together, you can use the formula:

Combined rate = Elias's rate + Niko's rate

Elias's rate = 1 job / 40 minutes

Niko's rate = 1 job / 50 minutes

So, the combined rate when they work together will be:

Combined rate = 1/40 + 1/50

Combined rate = (5/200) + (4/200)
