Gethyn drinks 48 fluid ounces of water in one day. He needs to drink 8 cups in total. How many more cups does he need to drink?


A) 2 cups
B) 6 cups
C) 384 cups
D) 768 cups

Answers

Answer:A

Step-by-step explanation:1 cup is equal to 8 fluid ounces so 48/8=6 and since he needs to drink 8 cups of water the answer is 2 more.

The number of cups of water Gethyn need to drink more is 2 cups. Therefore, option A is the correct answer.

What is metric conversion?

Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.

Given that, Gethyn drinks 48 fluid ounces of water in one day.

We know that, 1 ounce = 0.125 cups

Here, 48 fluid ounces = 48×0.125

= 6 cups

Number of cups of fluid = 8-6

= 2 cups

Therefore, option A is the correct answer.

how do you find the range of a triangle​

Answers

Answer:

To find a range of values for the third side when given two lengths, write two inequalities: one inequality that assumes the larger value given is the longest side in the triangle and one inequality that assumes that the third side is the longest side in the triangle. Combine the two inequalities for the final answer.

Step-by-step explanation:

Answer:

To find a range of values for the third side when given two lengths, write two inequalities: one inequality that assumes the larger value given is the longest side in the triangle and one inequality that assumes that the third side is the longest side in the triangle. Combine the two inequalities for the final answer.

Step-by-step explanation:

ex: a triangle has side lengths 3, and 7, find the possible range length for the third side.

Solution: let x be the length of the third side of the triangle

The maximum value:

x<3+7=10                            ______ x<10

The mimimum value:

x>7-3=4                          ________ x>4

so 4<x<10  ( x is between 4 and 10)

However, warming of the ocean along the shores of New England has caused the stock of cod to disappear almost completely. According to scientists at the Gulf of Maine Research Institute, the Gulf of Maine is heating up faster than a majority of the rest of the planet's oceans. As a result of warmer ocean waters, female cod produce fewer offspring, and these fish are less likely to survive to maturity. Even though recreational cod fishing was banned in 2014, and strict limitations were placed on the number of fish commercial fishermen could catch, these measures have not been enough to protect the cod.What is the main idea of the passage?A) Because cod use to be abundant in the Atlantic, it was once the backbone of the U.S. fishing industry.B) Female cod are producing fewer offspring in the Gulf of Maine.C)Because the Gulf of Maine is warming unusually quickly, Atlantic cod are disappearing.
