Answer:

4 seconds to reach 200 feet

Step-by-step explanation:

You can use Desmos (graphing calculator) then plug in the equation and you will find the x-values are 7.188 and 0- the origin.

Divide 7.188 by 2 (this is also solving for the midpoint/axis of symmetry) and you get 3.594

Round 3.594 to the nearest second which would be 4 seconds.

Hope that helps and have a great day!

Josiah has a piece of wood that measures 10 1 / 8 feet he wants to make 5 shelves if each shelf is 1 3/4 fuel long does he have
Salsk061 [2.6K]
To answer, I'm assuming "fuel long" means "feet long"
To find the amount of feet to make 5 shelves, we must multiply the amount to make one shelf by 5
1.75 * 5 = 8.75
(1.75 is the decimal form for one shelf)
Because 8.75 is less than 10, he has enough to make 5 shelves

Oliga [24]

Answer:

  Jill identified 8 <em>species</em> of plants. The number of plants identified is unknown.

Step-by-step explanation:

We are apparently to assume that the species Jill identified were either plants or animals. Hence 2/5 of those identified were plants. That makes the number of plant species ...

  (2/5)(20) = 8 . . . . plant species identified.

__

The question asks how many <em>plants</em> (not <em>plant species</em>) Jill identified. The problem statement does not give us sufficient information to answer that question.
