Emily leaves her house at exactly 8:25 a.m. to bike to her school, which is 3.42 miles away. When she passes the post office, wh
mafiozo [28]
First, let's find out the number of minutes Emily has to get to school. From 8:25 to 8:50, there are 25 minutes.

Next, let's find out  the number of minutes before Emily looks at her watch. From 8:25 to 8:28.50, there are 3.5 minutes.

Now let's calculate Emily's speed in miles per minute. To do so, divide the distance traveled by the time it took:

\frac{0.75}{3.5} miles/minute

Now let's calculate how far Emily can travel in 25 minutes going this speed. To do so, we multiply her speed by the time traveled:

\frac{0.75(25)}{3.5} =5.357 miles

5.357 miles is greater than 3.42 miles, so yes, Emily will make it to school on time.

Solve your equation using trail and improvement. A number plus ten times its square root is is equal to one thousand
Alex

Answer:

x \approx 729

Step-by-step explanation:

Given

Let the number be x

So:

x + 10\sqrt x = 1000

Required

Using trial and improvement, find x

This implies that we keep guessing the values of x until we get a value that match the equation.

Let

x = 625

So, we have:

x + 10\sqrt x = 1000

625 + 10 *\sqrt{625}

Take the square root of 625

625 + 10 *\sqrt{625} = 625 + 10 *25

625 + 10 *\sqrt{625} = 625 + 250

625 + 10 *\sqrt{625} = 875

Let

x = 729

So, we have:

x + 10\sqrt x = 1000

729 + 10 * \sqrt{729}

Take the square root of 729

729 + 10 * \sqrt{729} = 729 + 10 * 27

729 + 10 * \sqrt{729} = 729 + 270

729 + 10 * \sqrt{729} = 999

At this point, we can conclude that x is approximately 729 because

999 \approx 1000

So:

x \approx 729
