Answer:
2.99
Step-by-step explanation:
<em>Note: [log10 = 1]</em>
<em> [log8 = 0.903089987]</em>
2log10 = 0.3010
<em> </em>22log8 = x
Therefore:
<em>2log10 x = 22log8</em>
<em>x = 2.99</em>

Answer:
No, this set of ordered pairs does not represent a function.
Explanation:
Functions have one y-value for a given x-value.
Ordered pairs are written (x, y).
In this set, when x=2, it has four y-values (4, 5, 6 and 7), so it cannot be a function.
Answer:
3.5m is 500% of 70 cm and 70 cm is 20% of 3.5m.
Step-by-step explanation:
70 cm = 70cm/100= 0.7m
To solve the first problem use this equation:
3.5/0.7 *100 to get 500%
And to solve the second problem you use the same equation:
0.7/3.5*100 to get 20%
Hope this helps you.
