The length would be 10 inches.
to find perimeter, you add length+length+width+width.
since both widths and both lengths have to be the same, u add the width 2 times or 7+7=14.
next u subtract 14 from 34 or 34-14=20.
since u still have 2 lengths that are equal, u divide 20 by 2 or 20/2=10
hope this helps! :)
Answer:
80 lbs of Peanuts
Step-by-step explanation:
4 lbs per minute and we are looking for 30 mins.
1) 1.5x2=3 minutes
2) 30/10= 3 minutes
3) 4lbsx2 cycles of the machine= 8lbs in 3 minutes
4) we can take those 8 lbs and times them by 10 since we know 3 minutes is 1/10th of a 30 minute cycle.
5) 8x10=80
Let's find out.
David needs to score an average of 145 across all four games, so first we do:
145 × 4 = 580
Then we add all the scores he currently has:
139 + 143 + 144 = 426
Then we subtract 426 from 580 to find out how much he needs to score for his fourth:
580 - 426 = 154
David needs to score 154 on his 4th game to have an average score of 145 for all 4 games.
