Answer:
30 feet
Step-by-step explanation:
A ratio of 4:3 means that if one part can be represented by x, the original height is equal to 4 * x and the mural height is equal to 3 * x. This is because the ratio of original : mural is 4 : 3, so if one part = x, we have 4 * x : 3 * x. Therefore,
original mast height = 40 feet
4 * x = original mast height = 40 feet
divide both sides by 4 to get x
x = 10 feet
3 * x = mural mast height = 3 * 10 feet = 30 feet
The answer is B. 2772 square units
Answer:
-88
Step-by-step explanation:
If a=2, we can say that - would be -4.
Secondly, if a=2 and b=-6 we can assume that 4ab would become -48.
Finally, if b=-6 we can say that - would become -36.
Adding all of those up gives you -88, your answer.
A)it increased by 283
b)it stays the same
