3. Before tax, Louise spent a total of $38 on the items below at Starbucks
soldier1979 [14.2K]

Answer:

  47.4%

Step-by-step explanation:

The total amount Louise spent on Frappuccinos was 4×$4.50 = $18. The fraction that is of the total is ...

  Fraps/Total = $18/$38 = 9/19

That can be converted to a percentage by multiplying by 100%:

  9/19 = (9/19)×100% ≈ 47.4%

Louise spent 47.4% of the $38 on Frappuccinos.

_____

<em>Additional comment</em>

The decimal equivalent of 9/19 is a repeating decimal with an 18-digit repeat.

An object is thrown upward from the top of 80 ft tower.The height h of the object after t seconds is represented by the quadrati
Sedaia [141]

Answer:The object will hit the ground after 5 seconds


Step-by-step explanation:

Given height of tower =80 ft

h=-16t^{2}+64t+80

When the object will hit the ground its height=0

0=-16t^{2}+64t+80

Multiplying both sides by -1

16t²-64t-80=0

Dividing by 16 both sides

t²-4t-5=0

(t-5)(t+1)=0

t=5 or -1

So t=5 since time cannot be negative

The object will fall after 5 seconds
