Aboslute value|10 blocks| + |3 blocks| + |-8 blocks| + |2 blocks| + |-7 blocks| + |4 blocks| + |-4 blocks| = ?

1 answer:

5 0

Absolute or modulus always gives a positive number.
For example, when I take absolute value of 4, I get
|4| = 4 and when I take absolute value of -4, I get |-4| = -(-4) = 4.

Therefore, no matter what the sign of quantity is, absolute or modulus will always make it positive.
Therefore,
<span>|10 blocks| + |3 blocks| + |-8 blocks| + |2 blocks| + |-7 blocks| + |4 blocks| + |-4 blocks| = 10 + 3 -(-8) + 2 -(-7) + 4 -(-4) = 10+3+8+2+7+4+4 = 38</span>

Answer:

I don't think any of those answers represent pi

first of all the circumference of the circle is pi* diameter since the circumference of the circle is 43.96 feet and the diameter is 14 feet the equation would look like this 43.96=14*pi,pi=43.96/14,so that means the pi would obviously be 3.14

I´m pretty sure I´m correct.

if each person at a party will eat 3/8 roast beef and there will be 5 people at the party, how many pounds of roast beef will be

Cloud [144]

If each person eats 3/8 lbs of roast beef, 3/8 x 5 = 15/8. Simplify that down, you need 1 and 7/8 lbs of roast beef.
