EX: 29
+24
= 53

If u add the right side and it's over 9 then you have to put a 1 or whatever the first number is bc you can't put the full number which means you have to take the first number which is a 1 in my ex and put it in the left column. You should do this because u can't put the full.two digits down you have to regroup the 1.

Step-by-step explanation:

√a is defined only when a >= 0.

Therefore for √4x * √(x + 2) to be defined, both 4x and x + 2 must be non-negative.

When 4x >= 0, x >= 0.

When x + 2 >= 0, x >= -2.

x >= 0 and x >= -2, therefore we have x >= 0. (D)

Answer:

325,452 more meteors fell during the Perseid meteor shower

Step-by-step explanation:

An year has 365 days.

Each day has 24 hours.

Each hour has 60 minutes.

Minutes in an year:

365*24*60 = 525600

Persoid:

$1 + \frac{1}{5} = 1 + 0.2 = 1.2$

One each 1.2 minutes. How many during an year?

1 meteor - 1.2 minutes.

x meteors - 525600 minutes.

$1.2x = 525600$

$x = \frac{525600}{1.2}$

$x = 438000$

438,000 meteors fell during the Persoid shower.

Leonid:

$4 + \frac{2}{3} = 4.67$

One each 4.67 minutes. How many during an year.

1 meteor - 4.67 minutes.

x meteors - 525600 minutes.

$4.67x = 525600$

$x = \frac{525600}{4.67}$

$x = 112548$

112,548 meteors fell during the Leonid Shower.

How many more meteors fell during the Perseid meteor shower?

438,000 - 112,548 = 325,452

325,452 more meteors fell during the Perseid meteor shower
