Answer:
Step-by-step explanation:
We will assume that the first two columns are the numbers sold for Plain Wrapping and Decorative Wrapping. The third colum does not equal the sum of the first two, so we'll assume it is the total paid for both options. Let set the price of Plain Wrapping to x and the Decorative Wrapping to y. The number of gift wrappings times the cost per warpping is the product of x or y timers the number wrapped as shown in columns 1 and 2.
Take the first row and set it as an equation:
10x+9y = 47 [10 Plain Wraps and 9 Decorative Wraps bring a total of $47]
Do the same for the second and third rows:
25x + 12y = 86, and
16x +12y = 68
===========
We can take any equation and rearrange it to isolate one of the 2 variables, x or y. I'll pick 10x = 47-9y and isolate x:
10x = 47-9y
x = (47-9y)/10
-------------------
Now use this definition of x in another equation. I'll use 25x + 12y = 86.
25x + 12y = 86
25(47-9y)/10 + 12y = 86 [since x = (47-9y)/10 from above]
117.5 - 22.5y + 12y = 86
-10.5y = -31.5
y = 3 [the price for decorative wrapping is $3]
If y = 3, then we can use this in any of the equations to find x:
x = (47-9y)/10
x = (47-9(3))/10 [Use y = 3]
x = (47-27)/10
x = 2 [The price for plain wrapping is $3]
======================
Check to see if these values will expalin the total value of the three rows of numbers:
CHECK:
______UNITS____ $2 each $3 each
PlainW DecG Total PlainW ($) DecG ($) Total ($)

10 9 $47 $20 $27 $ 47 OK
25 12 $86 $50 $36 $ 86 OK
16 12 $68 $32 $36 $ 68 OK
The values work. Merry Christmas.

Answer:
80 degrees
Step-by-step explanation:
The 132-deg angle is an exterior angle of the left triangle.
The 52-deg angle is a remote interior angle to the exterior angle above.
Angle VZY is also a remote interior angle to the exterior angle above.
Theorem:
The measure of an exterior angle of a triangle is equal to the sum of the measures of its two remote interior angles.
We use the theorem above to find the measure of angle VZY.
52 + m<VZY = 132
m<VZY = 80
Angles WZX and VZY are vertical angles, so they are congruent.
m<WZX = m<VZY = 80
Answer: 80 degrees
Answer:
m∠WZX = 80°
Step-by-step explanation:
Angle V is a flat angle, so it measures 180°.
Find ∠YVZ (blue angle): 180° - 132° = 48°
Triangle VYZ is 180° (all triangles are 180°).
Find ∠YZV (red angle): 180° - 52° - 48° = 80°
Since you know ∠YZV, you can find ∠WZX (green angle).
∠YZV and ∠WZX are opposite angles, so they are congruent.
Therefore, ∠WZX = 80°
Hope this helps :)

I’m sorry for spam but I really need help
Only answer is you know the answer plz!
Answer:Triangle Inequality Theorem
The Triangle Inequality theorem states that
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
The Converse of the Triangle Inequality theorem states that
It is not possible to construct a triangle from three line segments if any of them is longer than the sum of the other two.
The length of s is greater than 3 and less than 11

I need help PLEASE !!!! Write a cosine function that has an amplitude of 2, a midline of 4 and a period of 4.
Answer:
[tex]\mathbf{y = 2cos ( \dfrac{\pi}{2}(x - 0) + 4}[/tex]
Step-by-step explanation:
The standardized cosine function is ;
[tex]\mathbf{y = Acos (Bx + C) +D}[/tex]
Amplitude |A| = 2
Period [tex]\dfrac{2 \pi}{B }= 4[/tex]
2π = 4B
[tex]B = \dfrac{2 \pi}{4}[/tex]
[tex]B = \dfrac{\pi}{2}[/tex]
Midline y = 4; D = 4
Phase shift; since no phase shift is given; then C = 0
The cosine function: [tex]\mathbf{y = 2cos ( \dfrac{\pi}{2}(x - 0) + 4}[/tex]

Find the total surface area
Answer:
47
Step-by-step explanation:
9+9+9+9+7+7
forgive me if i am wrong
Answer:
147 cm^2
Step-by-step explanation:
To find the surface area, you would have to add up the area of all shapes:
Area of triangle: 1/2 base*height
Area of square: length*width
----------
square = l*w = 7*7 = 49 cm^2
----------
So since there are 4 triangles, you would have to multiply the result by 4.
triangle = 1/2 7*9 = 49/2 = 24.5
4 triangles = area of 1 triangle * 4 = 4(24.5) = 98 cm^2
----------
add them up, and you get 49 + 98 = 147 cm^2

Loan amount = $9,500
Monthly payments = $227.50
Time of loan contract = 5 years
Interest rate = ____%
Answer:
Step-by-step explanation:
5x12=60
(227.5x5x120)=13650
13650-9500=4150
apply formula
(2x12x4150)/((13650(60+1))=0.1196
0.1196x100=11.96% 0r 12%
Answer:
17.2%
Step-by-step explanation:
given that:
y = 12 months
m = $9,500
n = 60 (because five years is 60 months)
c = (n * $227.50) - m
= (60 * $227.50) - $9,500
c = 4,150
and now, to substitute the following to the equation:
[tex]\frac{2(12)(4,150)}{9,500(61)} *100[/tex] = 17.2%
The net of a square pyramid is shown in the diagram.
What is the total surface area of the square pyramid in square inches?
Answer:
208
............
The total surface area of the square pyramid is 208 square inches.
What is Area?
Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -
V = ∫∫F(x, y) dx dy
Given is to find the total surface area of the square pyramid in square inches.
We can write the total surface area of the square pyramid as -
A{total} = A{square} + 4 x A{Δ}
A{total} = (8 x 8) + (4 x 1/2 x 8 x 9)
A{total} = 64 + (16 x 9)
A{total} = 208 square inches
Therefore, the total surface area of the square pyramid is 208 square inches.

Answer:
[tex]10\sqrt{313} +24\sqrt{194}+240[/tex] square units
Step-by-step explanation:
If your base is 10x24, and the vertical height is 13, you first have to find the slant height of the pyramid, in other words, calculate the hypotenuse of the triangles constructed using the height and the base divided by 2. You will need to find two slant heights as the base is not square. If you look at that image, the slant heights are marked in blue, and the specific measurements know are given in red. Using that, we can apply the Pythagorean theorem to determine the slant heights, which are [tex]\sqrt{194}[/tex] and [tex]\sqrt{313}[/tex], then we need to calculate the area of each triangular face. Thus they are [tex]5\sqrt{313}[/tex] and [tex]12\sqrt{194}[/tex], but there are two identical faces in the pyramid, which means we should double the area of the faces to achieve [tex]10\sqrt{313} +24\sqrt{194}[/tex], then we need to simply add the base as it's a face. So the answer is [tex]10\sqrt{313} +24\sqrt{194}+240[/tex]

x = -4, x = 4
Step-by-step explanation:
A denominator cannot equal zero since division by zero is undefined.
Set the denominator equal to zero and solve for x. That will give you the values of x that would cause the denominator to be equal to zero and must be excluded from the domain.
x^2 - 16 = 0
(x + 4)(x - 4) = 0
x + 4 = 0 or x - 4 = 0
x = -4 or x = 4
