Answer:
5.23×10^5
Step-by-step explanation:
You mean 56.23×10^4?
That would be 5.623×10×10^4, or 5.23×10^5
f = 2
Simplify both sides of the equation <span><span>1.25f</span>+2</span>=<span><span>−<span>2.75f</span></span>+<span>10
Add 2.75 to each side </span></span><span><span>4f</span>+2</span>=<span>10
Subtract 2 from both sides </span><span>4f</span>=<span>8
Divide each side by 4 </span>f=<span>2</span>

Correct answer is B. Begin it with the words "Antarctica is".
<h3>
what is Antarctica? </h3>
Antarctica The least inhabited and most southern continent on Earth is. It encompasses the geographical South Pole and is almost fully south of the Antarctic Circle, bordered by the Southern Ocean. With a surface area of 14,200,000 km2, Antarctica is the fifth-largest continent, being nearly twice the size of Australia and larger than Europe (5,500,000 sq mi). Ice blankets the majority of Antarctica, with an average thickness of 1.9 km (1.2 mi).
The continent with the greatest average elevation is Antarctica, which also tends to be the coldest, driest, and windiest overall. With around 200 mm (8 in) of yearly precipitation at the shore and much less inland, it is primarily a polar desert.

Answer:</h2>
<h2>
Step-by-step explanation:</h2>
We will use the Gaussian elimination method to solve this problem. To do so, let's follow the following steps:
Step 1: Let's multiply first equation by −2. Next, add the result to the second equation. So:
Step 2: Let's multiply first equation by −1. Next, add the result to the third equation. Thus:
Step 3: Let's multiply second equation by −35, Next, add the result to the third equation. Therefore:
Step 4: solve for z, then for y, then for x:
By substituting 
into the first equation, we get the 
. So:
percent ---------------- quantity
Acid type I 60.00% ---------------- x liters
acid type II 30.00% ------ 60 - x liters
Mixture 40.00% ---------------- 60
Total 60 liters
60.00% x + 30.00% ( 60 - x ) = 40.00% * 60
60 x + 30 ( 60 - x ) = 2400
60 x + 1800 - 30 x = 2400
60 x - 30 x = 2400 - -1800
30 x = 600
/ 30
x = 20 liters 60.00% Acid type I
40 liters 30.00% acid type II
