Answer:
she bought 27 yards of ribbon
Step-by-step explanation:
20 - 14.06 = 5.94
5.94/0.22 = 27
0.073.
2SF is 2 numbers excluding preliminary zeros,
In this case you look at the third digit, 8, and then round up to 0.073.

We can solve this by setting up 2 equations. We can use any letters like. For now, I'll use x and y.
So now we know that x - y = 0.7 and x + y = 1.
Now we can eliminate one of the letters by adding or subtracting one equation from the other. I am going to eliminate y by adding the two together (the y and the -y cancel).
This gives us 2x = 1.7, and so x = 1.7 ÷ 2 = 0.85
Finally, we can substitute x for 0.85 back into one of the original equations to figure out what y equals. I'm going to use x + y = 1.
So now we have 0.85 + y = 1, so y = 1 - 0.85 = 0.15
The numbers, therefore, are 0.85 and 0.15 (you can check by using the other equation).
Hope this helps!
The answer is (1 3/4, 8 1/4)
This is because if you check the previous values for x and y you can see that you have to add 2/4 to c and y.
Hope this helps!
If it does, it would be helpful to me if you could make me brainliest.
Each number in the code can be 1 of 10 numbers.
The total number of possible combinations is 10 * 10 * 10 * 10 = 10,000
The probability of getting 1234 would be 1/10,000
