Complete Question:
The smallest hummingbird is the Bee hummingbird. It has a mass of about 1 1/2 grams. The mass of a larger type of hummingbird is about 5 times the mass of the Bee hummingbird.
What is the mass of the larger humming bird?
Answer:
7 1/2 grams
Step-by-step explanation:
The mass of Bee humming bird is given in the question as = 1 1/2 grams
Mass of the larger humming bird = 5 times the mass of Bee humming bird
The mass of the larger humming bird is calculated as:
5 × 1 1/2 grams = 5 × 3/2 grams
= 15/2 grams = 7 1/2 grams
Therefore, the mass of the larger humming bird is 7 1/2 grams
3.5,
since 3350/670 = 5, we know that the 2345.0/670 = 3.5

Let c be children and a adults.
3.5c + 7a = 1771 (the total revenue is equal to the amounts made off of people)
c + a = 331 (total number of people)
The second formula becomes a = 331 - c. This can be substituted into the first formula.
3.5c + 7(331 - c) = 1771 = 7*331 - 3.5c = 1771. 7*331 = 2317, so 3.5c = 2317 - 1771 = 546.
546/3.5 = 156 = c (number of children).
c + a = 156 + a = 331 => a = 331 - 156 = 175 (number of adults).
There are 156 children and 175 adults
It would be D because you have to do the cube root on both sides. What I do is ignore the decimal and add it in later once the math is complete like on this question you can tell by process of elimination that 8 squared is 64 but you’re look for the cube root so that eliminates a and c and now just make sure the decimal is in the right place
