You can buy 5 cans for green beans at the village market for $2.10. you can buy 10 of the same cans of beans at sam's club for $5.90. which place is the better buy?

answer:

the 3 friends ate 1/5 of the pie.

step-by-step explanation:

the total of this pie is 5/5 so if josh and his brother ate 4/5 of the pie that means that there was 1/5 pie left so that is what the 3 friends ate.

answer:

  £11.20 – £33

step-by-step explanation:

the minimum value in the table is £11.20. the maximum value in the table is £33. the range of costs is the interval bounded by these values.

the difference between the maximum and minimum is £33 -11.20 = £21.80.

"range" has two possible meanings here. when "range" is applied to function values, it has one meaning. when "range" is applied to statistical data, it can have a different meaning.

choose the meaning as defined in your curriculum material.

answer:

t = 2.52 seconds

step-by-step explanation:

h=139-15t-16t^2

we want to know when the ball hits the ground

that would be when h=0

0 = 139-15t-16t^2

we can use the quadratic formula to find t

t = -b ± sqrt(b^2-4ac)

          2a

where a = -16   b = -15   and c = 139

t = ) ± )^2-4(-16)139)

          2(-16)

t = (15) ± sqrt(225+8896)

          -32

t = (15) ± sqrt(9121)

          -32

t = 15+ sqrt(9121)                       t = 15- sqrt(9121)

        or                      

            -32                                               -32

        -3.453247707         or               2.515747707

since time cannot be negative

  2.515747707

round to the nearest hundredth

t = 2.52 seconds
