1) Considering that there are 150 students
A) Adding 24+39 we got 63 students
150------------100%
63 ----------- x
x=6300/150
x= 42% of the students passed Math.
B) Adding the number of those students who live off-campus 39 +21
150 ----------------100%
60------------------ y
y=6000/150
y=40%
C) 60 students live off-campus 39 succeded. So we can write
60 --------- 100%
39 --------- z
z= 3900/60
z=65% passed math (off-campus)
D) Comparing that 65% of students who live off-campus passed math and that among those who live on campus and that 58% of all students failed
Then we can state:
A)
The first one, 4x is the slope and the +3 is the y-intercept
2019 is the answer. The way to solve this is by taking 1956 and take away 1949 from it. You will get 7. Add 7 to 1956. You will get 1963, which is on the chart. Then add 7 to 1963 and you will get 1970, which is also on the chart. Then from that point on keep adding 7 to the year until you get one of the answers. Hope this helps! :3
Here is the order:
1949-1956-1963-1970-1977-1984-1991-1998-2005-2012-2019
Volume of the original cube is a³ .
That's (a · a · a) .
If you decrease the sides to 20% of their original size,
then the new volume is (0.2a · 0.2a × 0.2a).
That's 0.008a³ or (0.2a)³ .
Take your choice. I can't decide which one is simpler.
