Answer:
0.5
Step-by-step explanation:
-0.35 x 1.43=0.5
3/7= .43
20% of 70 is 14.
Hope this helps!! :)
Answer:
Step-by-step explanation:
If 70% passed both, then that means 30% passed either one test, or neither test.
Since 80% passed the first test, we know that 20% of the students failed the first test.
This means that the other 10% of the students came from the 80% that already passed the first test.
These make up 10/80 = 12.5% of the people that passed the first test, meaning your answer is 100-12.5=87.5%
Answer:
R(16,-8)
Step-by-step explanation:
if (x1,y1) and (x2,y2) are coordinates of two points and (x,y) the coordinate of midpoint.
then x=(x1+x2)/2
and y=(y1+y2)/2
let coordinates of R are (x,y)
4=(-8+x)/2
8=-8+x
x=8+8=16
-3=(2+y)/2
-6=2+y
y=-6-2=-8
so R is (16,-8)
Step
<u>Find the length of the side MN</u>
we know that
Applying the Pythagorean Theorem
Solve for MN
in this problem
Substitute in the formula above
Step
<u>Find the value of cos (M)</u>
we know that
in the right triangle MNL
Substitute
therefore
The answer is
The value of cos(M) is equal to
