Answer:
The sides of an equilateral triangle are same. So if one of the sides is (x-4.5), all the sides are (x-4.5).
Let the sides are a=(x-4.5), b=(x-4.5), c=(x-4.5)
1. Perimeter(as sum) = a+b+c
= (x-4.5)+(x-4.5)+(x-4.5)
= x+x+x-4.5-4.5-4.5
= 3x - 13.5
2. Perimeter (as product) = 3×a
= 3×(x-4.5)
= 3×x - 3×4.5
= 3x - 13.5
(you can write 3×b or 3×c also as a=b=c.)
Both perimeter as sum and perimeter as product are same as adding a number three times is the same as multiplying it by 3.

Answer:
Coffee D, Coffee C, Coffee A, Coffee B
Step-by-step explanation:
We need to find the cents per ounce ratio
Coffee A: 3.67/11 = 0.33363636363 (0.33)
Coffee B: 11.64/20 = 0.582 (0.59)
Coffee C: 6.28/24 = 0.26166666666 (0.26)
Coffee D: 6.92/30 = 0.23066666666 (0.23)

Referring to the figure, find the surface area
of the pyramid shown. Round to the nearest whole number.
Answer:
297 is the surface area
Step-by-step explanation:
Ok this problem is very simple.
First lets define some equations.
Area of a triangle: A = 1/2BH
A = Area B = Base H = Height
This equation works for right triangles only.
(because 2 right triangles make a square which is why it's multiplied by 1/2 because it's half a square).
Area of a square: A = BH
Surface area equals all the areas of each side added together.
First lets find the area of one of the triangles.
We know 11 is the base and 8 is the height but the triangle isn't a right triangle.
To make it a right triangle divide the base by 2 so 11/2.
You will get 5.5.
Now find the area!
A = 1/2BH
A = 1/2(5.5)(8)
A = 1/2(44)
A = 22
So now we found the area of the right side as a right triangle but you must multiply it by 2 to get the entire side (because we divided the base by 2).
22(2)=A
44=A
44 is the area of one side of the pyramid but there are 3 other sides (not including the base).
So just do:
44+44+44+44 = A
176 = A
Surface area for the triangles is 176!
Now we must find the area of the square.
A = BH
A = 11(11)
A = 121
Total surface area is all the areas added together so it's:
121+176=A
297

In ΔOPQ, \overline{OQ} OQ is extended through point Q to point R, \text{m}\angle PQR = (4x-10)^{\circ}m∠PQR=(4x−10) ∘ , \text{m}\angle OPQ = (x+9)^{\circ}m∠OPQ=(x+9) ∘ , and \text{m}\angle QOP = (x-5)^{\circ}m∠QOP=(x−5) ∘ . Find \text{m}\angle PQR.m∠PQR.
Answer:
In
In to point R, \text{m}\angle PQR = (7x-19)^{\circ}m∠PQR=(7x−19) ∘ , \text{m}\a
Step-by-step explanation:
The sum of two interior angles other than the adjacent angle of extended length will be equal to the external angle of extended length thus m∠PQR will be 18°.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In any triangle,The sum of two interior angles other than the adjacent angle of extended length will be equal to the external angle of extended length.
In the given triangle below image,
m∠PQR = m∠OPQ + m∠POQ
4x - 10 = x + 9 + x - 5
4x - 10 = 2x + 4
2x = 14
x = 7
So,
m∠PQR = 4(7) - 10 = 18°
Hence "The measure of m∠PQR will be 18° for the given triangle".

Can anyone write me a definition of what Proportional Relationships are? (Must be exactly 5 words or less !! :D)
Two variables with equivalent ratios
I need help with Part A and B
Answer:
Part A) 700 Snack Bags
Part B) [$]1225.00
Step-by-step explanation:
Pretzels and cheese puffs make up 30% (0.30) of the sales which means 210 is 30% of the total bags they sold. You could set up a ratio like this where 1 represents 100%:
210/.30 = x/1
If solved out, you find there are 700 bags total and you can check it by finding that 210 is 30% of 700.

classify the equation 6(x + 2) = 5(x + 7) as having one solution, no solution, or infinitely many solutions
Answer:
Step-by-step explanation:
The equation has one solution.
6(x+2)=5(x+7)
6x+12=5x+35
6x+12-5x=35
6x-5x=35-12
x=23
Therefore, the equation has ONE solution.

3 liters of water are shared equally by 5 people how much water does each person get? division equation to represent the situation
600 mililiters each
Step-by-step explanation:
1 liter is equal to 1000 mililiter and is multiplied by 3 and the answer is devided into 5.
The division equation that represent the situation is 3/5 and each person will get 0.6 liters of water.
What is division?The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.
Now it is given that,
Number of People = 5
Liters of water = 3
So, Water shared by each person = Liters of water / Number of People
⇒ Water shared by each person = 3/5
This is the division equation to represent the situation.
⇒ Water shared by each person = 0.6
Thus, the division equation that represent the situation is 3/5 and each person will get 0.6 liters of water.
