(# of five dollar bills=f ; # of ten dollar bills=t)
3t-1=f ⇒ this means that if there were 1 $5 bills, there would be 2 $10 bills.
So the ratio of $5 bills to $10 bills is 1 to 2.
We can plug that into another equation:
f+t=410 ⇒ I havent actually learned this in school yet so I just made a chart: $10 ║ $5
------║------
2 ║ 1 = $25
4 ║ 2 = $50
6 ║ 3 = $75
8 ║ 4 = $100
10 ║ 5 = $125
and so on...
you probably found the pattern already, so you can conclude that [cathy deposited 16 five dollar bills and 33 ten dollar bills]
Also, you should probably check if there are any mistakes when going through this since I took almost an hour writing this.
3/8 = .375 so we want .375 of $5460.40 or .375 x $5460.40 = $2047.65 savings
To find the checking we simply subtract:
$5460.40 - 2047.65 = $3412.75 - checking
You could also do 5/8 or .625 x $5460.40 to get $3412.75
because 3/8 + 5/8 (or .375+.625) = 1 (1 whole amount to save - in this case $5460.40)
Mental math and associative property of addition
i look at 173 and 427 and see that
73+27=100
i add now the 100(from 173)+400(from 427)+100(see above)=600
easy
600+301=901
Answer:
<u>The correct answer is D. 4.55</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
What is the approximate value of 2π-√3?
2. Replacing the equation with the values:
π = 3.1416
√3 = 1.7321
2π-√3
2 (3.1416) - 1.7321 = 6.2832 - 1.7321 = 4.5511
4.55 (Rounding to two decimal places)
<u>The correct answer of 2π - 3 is D.4.55</u>
Because there are 8 scraps total, and there are 3 pink scraps. The probability of pulling out a pink scrap is 3/8.
