<span>1. Martina is given to be 14 years older than Joey who is x years old. Hence, the age of Martina can be expressed as,
x + 14
2. If Joey's current age is x then in 5 years he will become x+5 years old.
3. Martina's age will be her current age added with 5 making it, x+14+5 or x + 19.
4. The equation that would best represent the given scenario in this item is:
x + 19 = 3(x + 5)
5. From the given above, the value of x is equal to 2. This is Joey's current age.
6. The current age of Martina is x + 14 which is equal to 16.</span>
Answer:
4.58
Step-by-step explanation:
I assume it would just be 7(3) = 21
So = ~4.58
14,730,000 rounded to the nearest 10 million would be 10,000,000.
17,640,000 rounded to the nearest 10 million would be 20,000,000.
10,000,000+20,000,000=30,000,000
Think of the doghouse as being a rectangular prism bottom and a triangular prism on top.
volume of prism: area of the base * height
Rectangular prism:
The base is a square 4.5 ft by 4.5 ft.
The height is 3.0 ft.
volume = 4.5 ft * 4.5 ft * 3.0 ft = 60.75 ft^3
Triangular prism:
The triangle facing the front is the base. The height is the depth, 4.5 ft.
For the triangle, the area is bh/2, where b = 4.5 ft, h = 1.5 ft
volume = bh/2 * height
volume = 4.5 ft * 1.5 ft / 2 * 4.5 ft = 15.1875 ft^3
Total volume = 60.75 ft^3 + 15.1875 ft^3
Total volume = 75.9375 ft^3
