8 because 25% is 1/4 of how much he has so just multiply 2 by 4

d1i1m1o1n [39]

Answer:

It would cost $160 for 15 people to rent the bowling alley

Step-by-step explanation:

First, let's identify what we know:

1) It costs $100, just to rent the bowling alley.

2) We have to add $4 dollars, for every extra person.

3) The total cost can be found by using the expression 100 + 4n = x (n equals number of people, x equals total cost, 100 equals intial rent charge, and 4 equals the charge for each individual person)

So, just input 15 into the equation!

100 + 4(15) = x

100 + 60 = x

x = $160

AnnZ [28]

We are given

Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for the ball to fall 60 feet is 0.25(radical60).

so, time is

$T=0.25\sqrt{60} =\frac{1}{4} \sqrt{60}$

we have to approximate it's value

First approximation set:

we know that

$49$

we can take sqrt all the sides

$\sqrt{49}$

we can simplify it

$7$

Divide all sides by 4

$\frac{7}{4}< \frac{1}{4} \sqrt{60}$

Second approximation set:

$7.7$

Divide all sides by 4

$\frac{7.7}{4}$

$1.925$

Third approximation set:

$7.74$

Divide all sides by 4

$\frac{7.74}{4}$

$1.935$

so, we get

$t=1.94seconds$ ......Answer
