Daren draws a scale model of the Statue of Liberty that is 15 inches tall. If the Statue of Liberty is 305 feet tall, what is the scale of the model?
Answers
Answer:
The scale of the model is 1 : 244.
Step-by-step explanation:
15 inches = 1.25 feet. (1 inch = 0.0833333 feet)
Hence, the scale is 1.25 : 305 = 1 : 244. (1.25 / 1.25 : 305 / 1.25)

Find the surface area of the prism
Answers
=========================================================
Explanation:
The front triangular face is a triangle with base 8 and height 6. Its area is
A = 0.5*base*height
A = 0.5*8*6
A = 24 square feet
The back triangular face is also 24 square feet since these are the base faces of the prism. The base faces are always congruent. It might help to imagine this figure is turned on its side.
The slanted lateral face is a rectangle of length 10 ft and width 5 ft, so its area is L*W = 10*5 = 50 square feet
The rectangular face on the left is 6 ft by 5 ft giving an area of 6*5 = 30 square feet.
Lastly, the bottom rectangular face is 8 ft by 5 ft giving an area 8*5 = 40 square feet
Overall, the total surface area is: 24+24+50+30+40 = 168 square feet
We just add up all the individual areas of each face to get the total surface area.

What are the greatest common factor of 9a^b and 30ab^3?
Answers
Answer: 3ab IF a^b does NOT mean a to the power of b!
I believe you mean 9a²b and 30ab³
If you really mean 9aᵇ and 30ab³, then the GCF is 3a.
Step-by-step explanation:
the factors of 9 are 3*3 The factors of 30 are 2*3*5.
The only common factor of 9 and 30 is 3
a is a common factor of a and a²
b is a common factor of b and b³

4.5(8 - x) + 36 = 102 - 2.5(3x + 24)
Answers
Answer:
x = -10
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
4.5(8 - x) + 36 = 102 - 2.5(3x + 24)
Step 2: Solve for x
Distribute: 36 - 4.5x + 36 = 102 - 7.5x - 60Combine like terms: -4.5x + 72 = -7.5x + 42Add 7.5x on both sides: 3x + 72 = 42Subtract 72 on both sides: 3x = -30Divide 3 on both sides: x = -10Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 4.5(8 - -10) + 36 = 102 - 2.5(3(-10) + 24)Simplify: 4.5(8 + 10) + 36 = 102 - 2.5(3(-10) + 24)Multiply: 4.5(8 + 10) + 36 = 102 - 2.5(-30 + 24)Add: 4.5(18) + 36 = 102 - 2.5(-6)Multiply: 81 + 36 = 102 + 15Add: 117 = 117Here we see that 117 does indeed equal to 117.
∴ x = -10 is a solution of the equation.

Prasitha has two buildings A and B. A is 10 feet shorter than the twice the height of B. The distance between the buildings is 120 feet and the height of B is 60 feet. Find the distance between their tops.
Answers
Answer:
The distance between their tops is 130 feet
Step-by-step explanation:
The given parameters are;
The height of A, [tex]h_A[/tex] = 2 × The height of B - 10
The distance between the two buildings, d = 120 feet
The height of B, [tex]h_B[/tex] = 60 feet
Therefore, we have;
The height of A, [tex]h_A[/tex] = 2 × The height of B - 10 = 2 × 60 - 10 = 110 feet
The height of A, [tex]h_A[/tex] = 110 feet
By Pythagoras theorem, the distance between their tops = √(([tex]h_A[/tex] - [tex]h_B[/tex])² + d²)
Substituting the values gives;
The distance between their tops = √((110 - 60)² + 120²) = 130
The distance between their tops = 130 feet.
