Answer:oh tough one! iwould help but i cant see the pic :(
Step-by-step explanation:
It would be 2.9 because if the number to the right of the number your rounding is 5 or higher you round up to the next number. If the number is 4 or lower you round down to a 0.
Question 4:
Area = 1/2(A+B)*h
1/2(12+6)*5
1/2(18)*5
9*5
45
Question 5
Area = 1/2 (A+B)*h
1/2(12+16)*9
1/2(28)*9
14*9
126
Use simultaneous equation for this problem
y= number of adults
x = number of children
3y + 2x = 160
y + x = 60
then we double the second equation
3y + 2x = 160
2y + 2x = 120
we cancel x by elimination
3y - 2y = 160 - 120
y = 40
3 Tons = 6000 pounds
300 is 5% of 6000 so the answer is 5% :)
