A family of 2 children and 1 adult visited an amusement park and paid an entry fee of $90. Another family of 3 children and 2 ad

stiks02 [169]

$\underline{\underline{\large\bf{Solution:-}}}\\$

$\leadsto$ Let us assume entry fee for child be x

$\leadsto$ Let us assume entry fee for adult be y

$\\$

$\longrightarrow$ Since Entry fees for 2 children and 1 adult is $90 an equation for entry fees will be formed as -

$\begin{gathered}\\\implies\quad \sf 2\times x + 1 \times y = 90 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 2 x + y = 90 \\\end{gathered} \_\_\_\_\_(1)$

$\longrightarrow$ Similarly, Entry fees for 3 children and 2 adult is $155 , so an equation for entry fees will be formed as -

$\begin{gathered}\\\implies\quad \sf 3\times x + 2\times y = 155 \\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 3x + 2y = 155 \\\end{gathered} \_\_\_\_\_(2)$

Multiplying eq (1) by 2 it will be - 

$\begin{gathered}\\\implies\quad \sf 4x + 2y = 180\\\end{gathered}\_\_\_\_\_(3)$

Subtracting eq(2) from eq(3) - 

$\begin{gathered}\\\implies\quad \sf 4x+2y - (3x+2y) = 180-155\\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 4x + 2y - 3x - 2y = 35\\\end{gathered}$

$\begin{gathered}\\\implies\quad \sf 4x - 3x +2y- 2y = 35\\\end{gathered}$

$\begin{gathered}\\\implies\quad \bf x = 35\\\end{gathered}$

Thus , entry fee for a child at the amusement park = $ 35

A waterfall has a height of 1900 feet. A pebble is thrown upward from the top of the falls with an initial velocity of 12 feet p

saw5 [17]

Answer:

Step-by-step explanation:

h is the height of the pebble after a certain amount of time has gone by. Since we are told to find that time when the pebble is on the ground, we say that h = 0 since the height of something on the ground has no height at all. Then factor the quadratic.

$-16t^2+12t+1900=0$

Throw that into the quadratic formula or however you were taught to factor irrational quadratics (maybe completing the square?) to get that

t = 11.27869 sec and t = -10.52869 sec

Since we all know that time will never carry a negative value, we will disregard it and go with 11.27869 seconds. Not sure to where you are told to round.
