A scale model of an object has a scale of 1 cm : 2 ft. The actual object is 11 feet tall. How tall is the model? Show your work.
Answers
5.5 cm is the answer
Answer: 5.5 cm
Step-by-step explanation:
If you take 11 and divide it by 2 you would get 5.5cm. This is the answer because If 1cm is 2 ft you divide it by the actual height and you end up with how tall the model would be.
Hope that helps

Brittany and Will each made a triangular sign with an area of 8 square feet. The base of Brittany's triangle is half as long as the base of Will's. How do the heights of the triangles compare?
Answers
Answer:
the length of Brittany's triangular sign is 1/2 the length of Will's
Step-by-step explanation:
The height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).
How do the heights of the triangles compare?Let's assume the height of Brittany's triangle is h₁ and the height of Will's triangle is h₂.
For Brittany's triangle:
A = ¹/₂b₁h₁ = 8
For Will's triangle:
A = /₂b₂h₂ = 8
We are also given that the base of Brittany's triangle is half as long as the base of Will's triangle
b₁ = ¹/₂b₂
Now, let's find the relationship between the heights of the triangles:
From the equations above, we can see that:
h₁ = 16 / b₁
h₂ = 16 / b₂
Recall; b₁ = ¹/₂b₂
h₁ = (2 x 16) / b₂
h₂ = 16 / b₂
So, the height of Brittany's triangle (h₁) is 2 times the height of Will's triangle (h₂).

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

Mr. Nelson sold 84 bags of popcorn in 7 hours. At this rate, how many bags of popcorn will Mr. Nelson sell in 12 hours?
Answers
Answer:
144
Step-by-step explanation:
84 / 7 = 12
12 x 12 = 144
144 bags will be sold in 12 hours
Answer:
144 Bags Of Popcorn
Step-by-step explanation:
> First we need to identify how many bags he is selling an hour. We can do this by dividing 84 by 7, as he sold 84 in seven hours, so we’ll be finding how much he sold in one.
> We find that this equals 12, and as it says, “At this rate”. This means that it’s a constant, meaning the amount being sold an hour will not change.
> Knowing this we can simply multiply the 12 by 12 to get to the answer. The reasoning behind this being that since we are selling 12 and hour, and we are trying to see how many we will sell in 12 hours, we can multiply the two to get the answer.
> The answer to this is 144, so we can therefore find that the answer is 144 Bags Of Popcorn.

The 16 cases will fit the box as shown.
Step-by-step explanation:
One disk case has the dimensions 14.2 cm by 19.3 cm, with thickness 1.6 cm.
Temporarily ignoring the 14.2 cm and 19.3 cm measurements, we multiply this 1.6 cm thickness by 16, obtaining a total thickness for the stack of cases of 25.6 cm.
1) The 16 cases, arranged as shown, and measuring 25.6 cm from left to right in this diagram, will fit within the 26 cm horizontal distance shown.
2) The horizontal length of each case is 14.2 cm. Stacked as shown, the 16 cases will fit within the 15 cm depth of the box.
3) The vertical measurement of each case is 19.3 cm. The 20 cm vertical measurement of the box can accommodate this 19.3 height within 20 cm.
All indications are that the 16 cases will fit comfortably inside the box.
Answer:
16 discs capacity of the cuboid.
Step-by-step explanation:.
