Answer:
280.8 pounds
Step-by-step explanation:
Original weight of pig = 54 pounds
Percentage increase in weight = 420%
Current weight of pig = original weight + 420% of original weight
= 54 + 420% of 54
= 54 + 420/100 * 54
= 54 + 4.2 * 54
= 54 + 226.8
= 280.8 pounds
Current weight of pig = 280.8 pounds
Replace the x by x+3
so it would be
4log(x+3)
Answer:
the width is 17.5 feet and the length is 82.5 feet.
Step-by-step explanation:
The house has a rectangular shape and we know that the length is 5 feet less than 5 times the width.
We will call the width x, thus, the length would be represented as 5x-5 (5 less than 5 times the width).
Since Darrin is going to hang garland around the perimeter of the house, we know that the perimeter is 2 times the length plus two times the width and this equals 200.
Let's write this in algebraic form

Therefore, the width is 17.5 feet.
Now, the length is 5x-5, thus substituting the 17.5 in this equation we have:
feet
Therefore, the width is 17.5 feet and the length is 82.5 feet.
Answer:
Total area = 51 in²
Step-by-step explanation:
Section the shape into a rectangle and a triangle.
Area of a rectangle = width x length
⇒ area = 6 x 7 = 42 in²
Area of a triangle = 1/2 x base x height
⇒ area = 1/2 x (6 - 3) x (13 - 7) = 9 in²
Total area of composite shape = 42 + 9 = 51 in²
