They obviously didn't get the family membership pass.
Let c be the number of children, a be the number of adults
5c+30a=185
c+a=12 =>c=12-a
5(12-a)+30a=185
60-5a+30a=185
25a=125
a=5
c=12-5=7
there are 7 children and 5 adults.

In a video game, a bird is flung on a sling shot and follows a parabolic path. The path of the bird can be modeled by the equati

Novay_Z [31]

Answer:

The bird will take 0.88 seconds to reach a height of 40 feet in the air for the first time

Step-by-step explanation:

we have

$h=-16t^2+55t+4$

This is a vertical parabola open downward

The vertex represent a maximum

where

h is the height of the bird

t is the amount of time, in seconds, the bird had been in the air

For h=40 ft

substitute in the quadratic equation

$40=-16t^2+55t+4$

$-16t^2+55t+4-40=0$

$-16t^2+55t-36=0$

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$-16t^2+55t-36=0$

$a=-16\\b=55\\c=-36$

substitute in the formula

$x=\frac{-55\pm\sqrt{55^{2}-4(-16)(-36)}} {2(-16)}$

$x=\frac{-55\pm\sqrt{721}} {-32}$

$x=\frac{-55+\sqrt{721}} {-32}=0.88\ sec$

$x=\frac{-55-\sqrt{721}} {-32}=2.56\ sec$

therefore

The bird will take 0.88 seconds to reach a height of 40 feet in the air for the first time

If jake can write 450 words in 15 minutes how much can he write in 20 minutes?

Yanka [14]

Answer:

600 words

Step-by-step explanation:

To find how many words Jake can write in 20 minutes, you can find how many words he can write in 1 minute and multiply that by 20. Jake can write 30 words in a minute because 450 words divided by 15 minutes is 30. Then, multiply 30 by 20 which is 600.
