The number of pieces that Eliana need to take out is; 100 pieces
How to carry out Unit Conversions?
From conversion units, we know that 1 gram (g) is equal to 1000 milligrams (mg). Thus; 1 g = 1000 mg
Now, we are told that at the post office, she learns that her card is 5 grams too heavy for a common stamp. So, she takes out some of the confetti.
However, each piece weighs 50 milligrams. Converting to grams gives us; 50/1000 = 0.05 grams
Thus, number of pieces to take out = 5/0.05 = 100 pieces

Answer:
All 4 are solutions to the inequality.
Step-by-step explanation:
What we know:
The inequality requires that 48/f is less than or equal to 46.
Plug in each of the choices to see if that will work
48/12 ≤ 46
4 ≤ 46, so f = 12 will work.
48/-12 ≤ 46
-4 ≤ 46, so f = -12 will also work.
48/-3 ≤ 46
-16 ≤ 46, so f = -3 will work as well.
48/8 ≤ 46
6 ≤ 46, so f = 8 will work as well.
Since all 4 work, that means you should check all 4 choices on the question.

A boat travels 4 miles downstream in half an hour, and the same distance upstream in 2 hours. What is the speed of the boat in still water?
Answer:
7/3 mph
Step-by-step explanation:
knowing that:
distance traveled = velocity * time - velocity of the water * time
4 = v1 * 1.5 + v2 * 1.5
4 = v1 * 2 - v2 * 2
solve the system in any way you want,
v1 = 7/3 miles per hour
v2 = 1/3 miles per hour

What do you mean by data?
Data is information that has been transformed into a format that is useful for transfer or processing in computing. Information that has been converted into binary digital form for usage with contemporary computers and communication channels is referred to as data.
As the volume of data being collected and stored increases, so do the units used to measure it. For instance, the relatively new concept of a "brontobyte" refers to a unit of data storage that is 10 to the 27th power of bytes.
File formats can be used to store data, such as ISAM and VSAM in mainframe systems. Another file format for storing, converting, and processing data is comma-separated values.

12 roses costs $45.60, so in order to find the cost of one rose you have to divide the cost of 12 roses by 12, which gives $3.80.
Now that you know the cost of one rose, you can write an equation that gives you the cost in terms of the total number of roses by multiplying the cost of one rose by the total number of roses (x). This equation should be C = 3.8x
To find how much 18 roses would cost, you plug 18 into the previous equation for x, which gives you $68.40
Answer/Step-by-step explanation:
1. Well, we know that a dozen roses costs $45.60. We also know that a dozen is the same as 12. To know how much 1 rose costs, we need to divide $45.60 by 12.
45.60 ÷ 12 = $3.80. Therefore 1 rose costs $3.80.
2. y = yx
This is because the total amount of roses equal the cost of each rose multiplied by the amount of roses.
3. To find out how much 18 roses costs, we need to multiply the amount of one rose by 18. So, 3.80 x 18 = $68.4
Hope the helps! :D
