Step-by-step explanation:
Beth earns $54 per day and $10 for each extra hour she works. Ray earns $60 per day and $8 for each extra hour he puts in. They both work five days a week. The equations show their weekly earnings with respect to how many extra hours they work.
Beth: y = 270 + 10x
Ray: y = 300 + 8x
This system is graphed below.
Answer:
Associative Property
Step-by-step explanation:
When the order of operands remains the same, all operations are identical (multiplication, or addition), and only the parentheses change places, the property involved is the <em>associative property</em>.
Jabes travels 425.75km per day.
Unit rate is the amount of a certain item related to a single unit of another item.
In the question, we are given that Jabes traveled 3406km in 8 days
We have to find the distances that Jabes travel per day which will be the unit rate of distance per day.
The total distance that jabes traveled in 8 days = 3406 km
Thus, the distance per day jabes traveled can be calculated as:
8 days ⇒3406 km
or, 1 day⇒ 3406/8days = 425.75km
Thus,jabes traveled 425.75 km per day, using the unit rate.

Answer:
The higher you go in the good chain the lower the population.
Explanation:
In the food web, there are only a few sharks since in the food chain they are higher. Just 10% energy is retained in the tissues once the energy is moved from one trophic level to another, and the leftover power is emitted as metabolic energy.
If an animal is high up the energy ladder, the individual has less resources; thus, a few of the highest predators are present in an ecosystem.
Answer:
58330.5 bones
Step-by-step explanation:
Essentially mean is taking the total and dividing that by the number of items.
Here, we need to add up all the bones and divide it by the number of dogs there are:
444 + 555 + 101010 + 131313 = 233322 bones
There are 4 dogs:
233322 / 4 = 58330.5 bones
