If Alaska were divided into 10 equal pieces, then that means Florida would be the same size as one of those pieces. So write the equation $1,700.000 * \frac{1}{10}$ .

This is equal to $\frac{1,700,000}{10}$ .

Now, when you divide a number by 10, the original number becomes one place value less. For instance, 2 ÷ 10 = 0.2.

We can see that 1,700,000 has 5 zeroes, so if you divide it by 10, the this means Florida is 170,000 sq km.

Hope this helped. :D

Answer:

Confused as well

Step-by-step explanation:

If there are hypothetically 10 hours a day with 100 minutes an hour and 100 seconds per minute

at 6 pm there would be 18 hours gone in the day

18 normal hours are equal to 18*60*60 = 64800 seconds

(64800 seconds) / 10000 ( for hours)

6:48 would be the replacement time

but this answer is wrong bc it's not an option

A rock falls off a balcony. It’s height(in feet)is given by the formula f(x)= -16t^2+12.5t+150, where t is measured in seconds.

ELEN [110]

Answer: $3.47\ seconds$

Step-by-step explanation:

Given the following function:

$f(x)= -16t^2+12.5t+150$

You need to follow these steps in order to solve the exercise:

1. Substitute $f(x)=0$ :

$0= -16t^2+12.5t+150$

2. Now you need to apply the Quadratic formula. This is:

$x=t=\frac{-b\±\sqrt{b^2-4ac} }{2a}$

In this case, you can identify that:

$a=-16\\b=12.5\\c=150$

Then, you can substitute these values into the formula:

$t=\frac{-12.5\±\sqrt{(12.5)^2-4(-16)(150)}}{2(-16)}$

3. Evaluating, you get:

$t_1=3.47\\\\t_2=-2.69$

4. You must choose the positive value. Then:

$t=3.47\ seconds$
