Answer:
About <em>4 hours.</em>
Step-by-step explanation:
To find the answer we will <em>add both percentages</em> of <u><em>Watching TV</em></u> and <u><em>Homework</em></u>. 8% + 13% = <em>21%</em>. Now we will <em>divide 100 by 21</em> and we get<em> 4 hours a day.</em>
That little squaer angle means right angle or 90 degrees
the black line and the red line cross
therefor the oposte angles are eqal measure
7x=90+x
solve
minus x
6x=90
divide 6
x=15
x=15
a) 9 toilet rolls cost $ 4.23
1 toilet roll costs $ x
9x = 4.23 * 1
x= 4.23 / 9
x = 0.47
So in first case one toilet roll costs $ 0.47.
b) 4 toilet rolls cost $1.96
1 toilet roll costs $ x
4x = 1.96 * 1
x = 1.96 / 4
x = 0.49
So in second case one toilet roll costs $ 0.49.
0.47 < 0.49
The toilet roll in first case is cheaper than the toilet roll in second case.
Hope this heps!
Answer:
100000000
Step-by-step explanation:
6 times 10 to the 8th is 600,000,000
5 times 10 to the 7th is 500,000,000
600,000,000-500,000,000=100,000,000
