If he spends 1/4 reading the news, then he spends 3/4 reading the other stuff
3/4 * 8/9 = 24/36 = 2/3 of an hr ...time spent reading sports and comics
(2/3) / 2 =
2/3 * 1/2 = 2/6 reduces to 1/3....so he spends 1/3 of an hour (or 20 minutes) reading the comics
Answer:
8.612 x 10⁶
Step-by-step explanation:
Given problem:
(8.60×10⁶) + (1.2×10⁴)
Solve by the process of scientific notation;
Solution:
(8.60×10⁶) + (1.2×10⁴)
Adjust the exponent so that they are of the same value;
8.6 x 10⁶ = 860 x 10⁴
So;
(860 x 10⁴) + (1.2×10⁴) = (860 + 1.2) x 10⁴
= 861.2 x 10⁴
or
8.612 x 10⁶
Answer:
= Sh. 2281.50
Step-by-step explanation:
Area of the path;
(126 × 2.5 ) + (2.5 × (48 - (2.5×2)
= 315 + (2.5 × 43)
= 315 + 107.5
= 422.5 m²
But; the cost of graveling is sh 5.40 per square meter
Therefore; The cost of graveling the whole path;
= 422.5 × 5.40
<u>= Sh. 2281.50</u>
