Step 1 is, "draw arcs through both legs of the angle, centered at the vertex of the angle."
_____
The arcs crossing the two legs have the same radius. One arc crossing both legs can be used, if you like.
If you're twice a fast then... we'll divide 6750 by 3, that equals 2250.
<span>Equation.. y=your friend and you would be 2y cuz you're twice as fast.
</span>y+2y=6750,
3y=6750
y=2250
Your friend stuffed 2250 in 4.5 hrs.
You (twice as fast) stuffed 4500 in 4.5 hrs.
Working alone, your friend can stuff 2250 in 4.5hrs so it would take 13.5hrs to stuff 6750.
Equation.. (6750/2250) x 4.5hrs = 13.5hrs
You can 4500 in 4.5hrs so it would take you 6.75 hrs to stuff 6750.
Equation.. (6750/4500) x 4.5hrs = 6.75 hrs.
Answer: the second fifth and sixth one
Step-by-step explanation:
Answer:
5C
6C
7D
8B
Step-by-step explanation:
5) C because median is the middle of the set of numbers source A median is 4 source B median is 6 and 4 is 2 less than 6.
6) C because there are 6 numbers altogether and 1 6s on a dice so 6+6 because we have two dice and 2 6s on both so 2/12 or simplified 1/6
7) D because mean is all the numbers add up divided by the amount of numbers so 20+25+30+20+30 = 125 and 125 ÷ 5 = 25
8 B because mean is all the numbers add up divided by the amount of numbers so
5+6+7+8+8+8+8+8+8+9+9 = 76 ÷ by 10 is 7.6
7+7+7+7+8+8+8+8+10+10 = 80 ÷ by 10 = 8
8 + 7.6 = 15.6 ÷ 2 = 7.8 and B is closest to 7.8
