Answers:
4. m PQ: 50 degrees
m PXQ: 310 degrees
5. m PQ: 90 degrees
m PRQ: 270 degrees
Explanation: the central angle is equal to its corresponding arc. The larger arc is found by doing 360- smaller arc degrees.
Answer:
B. 3 to 10
Step-by-step explanation:
She uses 3 scoops of hot cocoa.
She uses 10 miniature marshmallows.
The ratio of scoops of hot cocoa to miniature marshmallows is 3 to 10.
Remember, to be a function, all elements in the domain should correspond to one element in the range.
The domain is the x coordinate, range is the y coordinate.
The domain we can solve for as the set {4.2, 5, 7}. The range is the set {0, 1.5, 2.2, 4.8}.
But we see that an element in the domain corresponds to more than one element in the range, thus making it not a function.
Answer:
C) Commensalism has no effect on the species, while parasitism has a negative effect.
Explanation:
Commensalism and parasitism are both forms of species interaction.
Commensalism:
Commensalism refers to an ecological relationship between two species where one species benefits from the other but the other is neither harmed nor benefited. For example, remoras are little fish that attach to sharks and other larger fish. Remoras benefit in terms of protection, transport and food. They feed off scraps attached to the shark's mouth and teeth. However, the shark neither benefits nor suffers from this interaction.
Parasitism:
Parasitism is a relationship between a host and a parasite where the parasite benefits at the expense of the host. the parasite attains benefits while harming the host. For example, ticks and fleas that infest dogs. The ticks attain nutrients from the host's blood and in turn, weaken and harm the host.
The pair of numbers can be 70300 and 73.
Let us assume that the second number is 73.
7 in 73 is 70 or 7 x 10
3 in 73 is 3 or 3 x 1
Since the 2nd 7 is 70 and the 1st 7 should be 1000 times the value of the 2nd number. then 70 x 1000 = 70000
The 1st 3 is said to be 100 time the value of 3 in the second number.
3 x 100 = 300
first number: 70000 + 300 = 70300
second number: 70 + 3 = 73
