171.875 pounds of flour and 103.125 pounds of sugar should be ordered.
What is a pound?The pound is defined as the basic unit for weight in the Foot Pound Second (F.P.S) system and is equal to 16 ounces.
To find the amount of flour in pounds we need to find the 62.5% of 275.
62.5% of 275 = 171.875
To find the amount of sugar in pounds we need to find the 37.5% of 275.
37.5% of 275 =103.125
Hence, 171.875 pounds of flour and 103.125 pounds of sugar should be ordered.

Composition of matter
I need help with this
Answer:
129 units cubed
Explanation:
There are ten spaces between 120 and 130, so we can infer that each line represents a change in volume of 1 unit. The volume of the substance in the graduated cylinder looks like it's 1 under 130, so its volume is 129 units.

Perform the following operations giving the proper number as a benefit get figures in the answer.
Help
Answer:
Use calculator but first group them one by one and open the bracket by solving them accordingly
The number we get by this operation is 0.016. This number can be taken based on the rules for significant figures.
What is significant figures?The number of significant figures is the number of digits that are known with certainty plus the last one having some uncertainty. All non zero values are significant and zero preceding first non zero digit is not significant .
For example in 65000, there are only two significant figures. Similarly in 0.08 only one significant digit is present. Now when we multiply two decimal numbers, the result can only have as many decimal places as there are in the value with fewest decimal places.
First, multiply the numbers inside the bracket. As per the above rule, the result should contain only two decimal places.
(0.08 ×200×0.004) = 0.06
Multiply by 65000 - 0.06×65000 = 3900
Now divide it by the multiplication product (800× 300), 240000 we get as follows:
3900÷240000 = 0.016
Hence the result of this operation is 0.016.

Where does the energy of a hurricane come from? (1 point)
O the Sun
O strong winds
O Earth's spin
O Earth's moon
Answer:
strong winds come from the energy of a hurricane
The energy of a hurricane come from strong wind. The Taino Native American term hurricane, which translates to "bad spirit of the wind," is where the word hurricane originates.
What is hurricane ?A tropical storm that has sustained winds of 74 mph or greater is referred regarded as a hurricane. A storm's eye typically measures 20 to 30 miles in width and can reach distances of 400 miles. Storms can be dangerous because of their torrential downpours, strong gusts, and storm surges.
When warm, humid air begins to rise over water, hurricanes emerge. Cooler air replaces the rising air. Large clouds and thunderstorms continue to grow as a result of this process. Thanks to the earth's Coriolis Effect, these thunderstorms are still expanding and starting to rotate.
Thus, option B is correct.
