Answer:
x + y = 400
5x + 9y = 2632
Step-by-step explanation:
This can be solve by using the average cans of each student
collected and muliply it by the total students. Since for ms. Lee has 24
students and each student collected 18 cans on average, so the total can her
class collected on average is 432 cans. For mr galveshas 21 students and
collected 25 can per syudents on average, so the total is 525 cans. So 525 –
432 = 93 more cans the class of mr galvez collected
Answer:
540 megabytes
Step-by-step explanation:
We will first need to find out how much space a<em> singular song</em> will take up. We will do this by <em>the storage taken up (884) by the number of songs she has:</em>
884 / 221 = 4 mb taken up per song
Then we want to find out how many megabytes <em>135 of these songs take up</em>, so we will multiply the <em>mb taken up per song (4) by the number of songs we want to find (135)</em>:
4 x 135 = <em>540 megabytes</em>

Answer:
6
Step-by-step explanation:
3(1)=3 3(2)=6 3(3)=9 3(4)=12 3(5)=15
3(6)=18 3(7)=21 3(8)=24
----------------------------------------------------
3(6)=18 is closest to 20
so the greatest number of batches Xiaoming can make is 6.
All the components in the state vector need to sum to 1. You're given that component corresponding to state 1 is 0.2, and that the component for state 3 is 0.
That leaves states 2 and 4, for which you're told that the component for state 2 is four times as large. If

is the component for state

, then you have

which means

. So the state vector is

.
