Mary's backpack: 25% of 65 = 0.25 * 65 = 16.25; 65 - 16.25 = $48.75
Roberto's backpack: 30% of 75 = 0.3 * 75 = 22.5; 75 - 22.5 = $52.5
Mary's backpack was a better buy because it was cheaper.
Answer:
a) yes b) no c) no
Step-by-step explanation:
In order to know this, remember something: to do the division between a number and a rational number like this and with zero to the left, the best way to solve them is converting these number to a natural number.
To do that, you only need to multiply the number by 10, 100, 1000, depending of how many decimals it have.
In case a) 0.05 has two decimals, therefore we multiply by 100:
0.05 * 100 = 5
However, when you do that, you have to do the same thing with the number in the dividend, in this case, 1.4:
1.4 * 100 = 140
So we can conclude that 1.4 you have to add a zero to do the division.
Case b) and c) do not apply, in both cases we multiply by 10 and we get this:
25.2 and 6,
26.1 and 3.
Answer:
(a)25.45 million viewers
(b) 11.95 million viewers
Step-by-step explanation:
The average number of viewers from the 2011 season through the 2013 season is approximated by the function:
(1 ≤ t ≤ 4) where f(t) is measured in millions.
t = 1 corresponds to the 2011 season.
(a) In 2011, t=1
Average number of viewers in the 2011 season,
=25.45 million viewers
(b) In the 2014 season, when =4
=11.95 million viewers
assuming that the trend continued into that season
Answer:
-6
Step-by-step explanation:
Substitute -2 from x meaning -2^3+-2^2-3*-2; solve this, you get -6!
