Answer:
4.82
Step-by-step explanation:
0.000082 + 0.0004 = 0.000482 = 4.82
Divide $435.15 by 9 = $48.35 unit price
2.33 is the aprox number we start off with. if we got to find the original, we divide 560 by (7/3).
after we estimate the divisior we get 240. 560 - 240 gives us 320.
the answer could be 320.
Answer:
$32 + $0.25x < $50
Step-by-step explanation:
1.he buy a backpack for $32
2. he buys x amount of pencils. Each pencil cost 0.25. ($0.25x)
3. all of that is less than(<) $50
To solve this, I used guess and check.
I started by finding 60²=3600 and 70²=4900. 70² is too much, so I then did 65²=4,225.
After 65², I did 62²=3,844. I knew that was pretty close, so I did 64. 64²=4,096 and 63²=3,969. So, 64² was it.
4,096-4015=81
So, you would need to add 81 to 4015 in order to receive a perfect square, which is 64²(4,096).
