<span>the change in the amount of water in the pitcher is</span>5/8 cup
Answer:
Step-by-step explanation:
(-8a - 1)- (-7a + 5) = -8a - 1 - 7a*(-1) + 5*(-1) { (-1) is disturbed to all the terms in (-7a +5)}
= -8a - 1 + 7a - 5
= -8a + 7a -1 - 5 {Combine like terms}
= -a - 6
The half life would be about 3 so making the percentage About 25%
A=(a+b)*h*1/2=(20+8)*7*1/2=49 m2
V=A*H=49*2=98 m3
Answer: -10 ÷ -2/5
Step-by-step explanation: this would equal 25 which is greater than 10. Hope this helps!
