It would still be 80
Example:
<span>14,494 </span>
<span>To round off the height value to the nearest thousand we can use the expanded from to clarity the position of numbers which is: </span>
<span>10, 000 = ten thousand </span>
<span>4, 000 = thousands </span>
<span>400 = hundreds </span>
<span>90 = tens </span>
<span>4 = ones </span>
<span>Here we can notice than four thousand is the value where the nearest thousands is placed. Hence we can round off the number of 14, 494 into 14, 000. Notice 0-4 rounding off rules.<span> </span></span>
a. log₈8 = 1
b. log₇6/5
c. log₉3¹
<h3>The solution to the problem are</h3>
1. log₈ 2 * 4 would produce an integer
= log₈8 = 1
The output is an integer
2. log₇6/5 would give us an irrational number
= log₇1.2
This would give us an irrational number
3. log₉3¹ would give us a rational number
= log₉9^
= 1/2 log⁹9
= 1/2

Answer:1) 9/8×4/3
2)9/8÷3/4
3)3/2
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
1) the basic is: the mass of the salt before pure water is added = the mass of the salt after the pure water is added;
2) the mass of the salt before pure water is added was:
40*0.1;
3) the mass of the salt after pure water is added is:
(40+w)*0.05, where w - the required mass of pure water;
4) if the mass of the salt is the same, then:
40*0.1=(40+w)*0.05;
5) if to evaluate the equation:
(w+40)*0.05=4; ⇔ w+40=80; ⇔ w=40 gr.
