Answer:
the total amount spent is $31.68
Step-by-step explanation:
The computation of total amount spent as follows:
= 1.4 pounds × $9.15 + 0.8 pounds × $10.75 + 2.6 pounds × $3.95
= $12.81 + $8.6 + $10.27
= $31.68
hence, the total amount spent is $31.68
We simply apply the pounds with its price
Answer:
-220
Step-by-step explanation:
when the equation has a value of 0 of course the coin lands, so we need to find what x leads to that value.
-16x^2-16x+60=0
We can first divide by 4 on both sides.
-4x^2-4x+15=0
Now multiply -1
4x^2+4x-15=0
(2x-3)(2x+5)=0
x=3/2 or -5/2
But because how many seconds have to be positive, x=-5/2 is an extraneous solution.
The time it have to stay in the air is 3/2 seconds.
