When the​ women's soccer team won the state​ championship, the parent boosters welcomed the team back to school with a balloon b
slega [8]

Answer:

3 foil, 6 latex

Step-by-step explanation:

First, you can put all of these words words into equations. We know there are 162 ballons (18 players)(9 bouquets). So we can put it in the equation

x + y = 162

Since each foil balloon costs $1.92 and each Latex balloon costs $.19 and they all cost $124.20. We can put it in an equation:

.19x + 1.92y = 124.20

You then get the systems of equations:

x + y = 162

.19x + 1.92y = 124.20

solving for the equation, you get x = 54 and y = 108. BUT, you have to be careful. The problem said "How many of each type of balloon did each <em>bouquet</em>​ include?" So we need to divide both by 18 for the player because each player recieved on bouquet.

A grasshopper jumps off a tree stump. The height, in feet, of the grasshopper above the ground after t seconds is modeled by the
Monica [59]

The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function , which is

h(t) =-t^2+\frac{4}{3}t+ \frac{1}{4}

When the grasshopper land on the ground,

h(t)=0

that is,

-t^2+\frac{4}{3}t+ \frac{1}{4}=0

Multiplying whole equation by 12 to get rid of denominators 3 and 4

-12t^2+16t +3=0

(3-2t)(6t+1)=0 \\ 3-2t=0 , 6t+1=0 \\ t= \frac{3}{2} , \frac{-1}{6}

And time cant be negative, so the correct option is

t = \frac{3}{2}=1.5 seconds

Correct option is C .
