PLEASE HELP ME PLS ITS MATH

Ganezh [65]

Answer:

9

Step-by-step explanation:

We know that

$h(t)=-16t^2+1296$

The balls hits the ground when h(t)=0, so

$-16t^2 + 1296=0 \\ \\ t^2 - 81=0 \\ \\ t^2 = 81 \\ \\ t=9$

Note I only considered the positive case because time must be positive.

Josh can paint a whole room in m hours while Kevin can paint a whole room in n hours. How many parts of the room can they paint

Leona [35]

<h3>Answer: (m+n)/(mn)</h3>

Work Shown:

Josh:

1 room = m hours

1/m room = 1 hour

Kevin:

1 room = n hours

1/n room = 1 hour

We see that the rates for Josh and Kevin are 1/m and 1/n respectively. This is the amount of a room they paint in one hour. Combine the fractions

1/m + 1/n = n/(mn) + m/(mn) = (n+m)/(mn) = (m+n)/(mn)

The expression (m+n)/(mn) represents how much of the room they get painted in 1 hour. This is if they work together and it assumes neither worker slows the other one down.

Lucas ate a fraction of a pizza. Hugo ate 5/8 of the same pizza. Now there is 1/8 of the pizza left what fraction of pizza did L

MatroZZZ [7]

Answer:

$\frac{2}{8}$

Step-by-step explanation:

In order to solve this equation we will need to use what we know in order to find the answer.

$1=\frac{8}{8}$

$H=\frac{5}{8}$

$R = \frac{1}{8}$

If Huge ate 5/8's of the pizza and 8/8's creates a whole pizza then the question is quite simple. There is only 1/8's remaining after the boys finish their meal but 5/8's of the pizza was already eaten by Hugo meaning Lucas has to eat 2/8's of the pizza in order for there to be only 1/8's of the pizza left which means 2/8's is your answer.

Hope this helps.
