Answer:
Step-by-step explanation:
The amount of integers between 
and 
inclusive is always 
.
This means the amount of integers Michael wrote is 
. Because 
, which gives 
, 
is always non-negative. So, we can kick out the absolute value sign to get 
.
So, he wrote 
integers and we're done!
Slope of line l (m1)=5
Slope of line w(m2)=-1/5
Since,m1×m2=-1 , line 'l' and 'w' are perpendicular.
Since line 'k' doesn't intersect line 'l' ,they must be parallel b'coz they are in the same plane as well.
Here, 'l' is perpendicular to 'w' and parallel to 'k'....so w and k must be perpendicular to each other.
It can be proven:
Since l and k are parallel, their slopes are equal.
So, slope of k (m3)=5
Since m3×m2=-1 ,w and k are perpendicular.
Hence, angle between w and k is 90°
Each long piece is composed of 10 unit blocks (smallest squares).
The three long pieces means that they make up 3*10 = 30 units so far. Add on the 5 extra units and we have 30+5 = 35 units total
If we have 35 squares, then we can group them up into groups of 5. Doing so will leave you with 7 groups.
Answer:
-1 and -4
Step-by-step explanation:
-1 + -4 = -5
-1 times -4 = 4
give brainiest please!
hope this helps ;)
D is the correct answer.
0.25 is rational because it can be represented as a ratio of integers (1/4).
0.45 is rational because it can also be represented as a ratio of integers (9/20).
When you multiply rational numbers, you always end up with a rational number.
0.25*0.45=0.1125 or 1125/10000
