samantha threw an apple out of a window from the tenth floor of her appartment building. the equation y = -16t^2+120 can be used

ella [17]

Answer:
time taken = 2.74 seconds

Explanation:
We are given that:
y = -16t² + 120 models the situation where:
y is the floor number
t is the time taken for the apple to hit the ground

We are also given that the floor number (y) is 10. Therefore, all we have to do is substitute with y in the above equation and solve for the time t as follows:
y = -16t² + 120
10 = -16t² + 120
120 - 10 = 16t²
110 = 16t²
t² = 110/16
t² = 6.875
either t = 2.74 seconds ..........> accepted
or t = -2.74 seconds .........> rejected as time cannot be in negative

Hope this helps :)

Naddik [55]

Let's solve your equation step-by-step.

2b+1=16−3b

Step 1: Simplify both sides of the equation.

2b+1=16−3b

2b+1=16+−3b

2b+1=−3b+16

Step 2: Add 3b to both sides.

2b+1+3b=−3b+16+3b

5b+1=16

Step 3: Subtract 1 from both sides.

5b+1−1=16−1

5b=15

Step 4: Divide both sides by 5.

5b/5=15/5

<em>answer: b=3</em>

vaieri [72.5K]

If we know that 30% of the time is used after 9 minutes we can write this mathematically as:

$0.30x = 9$
By solving for x we can determine the total time allowed to play games and so:

$x = \frac{9}{0.30} = 30$
The total time allowed to play games is 30 minutes. Since 9 minutes have lapsed 30-9=21 minutes left to play.
