Answer:
2 animals
Step-by-step explanation:
Number of animals=40
Fraction of fish=3/4
=>number of fish=3/4*40=30
Fraction of cats=1/5
=>number of cats=1/5*40=8
Animals which are not cats or fish are=total number of animals-(number of cats + number of fish)
Animals which are not cats or fish=40-(8+30)
40-38
2 animals
Answer:
The midpoint is (3/2,0)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinate of the endpoints and divide by 2
(7+-4)/2 = 3/2
To find the y coordinate of the midpoint, add the y coordinate of the endpoints and divide by 2
(-2+2)/2 = 0
The midpoint is (3/2,0)
Answer:
-1875
Step-by-step explanation:
An arithmetic sequence has a common difference as a sequence. Here the common differnece is -11.
So our sequence so far looks like,
(57,46,35,24....). We know the last term of the sequence is -207 and we need to find the nth term of that series so we use arithmetic sequence
where a1 is the inital value,
d is the common differnece and n is the nth term.
We need to find the nth term so
So the 25th term of a arithmetic sequence is last term, now we can use the sum of arithmetic sequence
which is
Answer:
C. (2,4), (-3,2)(2,1)(-7,2) is not a function.
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
for 1)
angle y = 180 - 110 = 70 degrees
angle z = angle y = 70 degrees
angle x = 89 degrees
for 2)
angle 1 = 180 - 85 = 95 degrees
angle 2= 180 - 95 - 85 degrees
angle 3 = 180-95 = 85 degrees
for 3)
m angle 3 = 25 degrees, same as m angle 1
