The answer is 85% and this is how it can be calculated:
Total correct answer= 40- incorrect
Total correct answer= 40 - 6
34/40= 0.85 or 85%
The other way of finding the answer is that, First find the percentage of incorrect and then deduct it from 100%. Like
6/40 = 15%
Percentage of Correct answers= 100%-15% = 85%
Remember
P=2(l+w)
w=wdith
l=legnth
w is 3/4 legnth
w=3/4l
P=50 when l+2 and w+2
so
50=P=2(l+2+w+2)
w=3/4l, so sub
50=2(l+2+3/4l+2)
divide everybody by 2 to ge rid of nasty parenthasees
25=l+2+3/4l+2
25=1 and 3/4l+4
minus 4
21=1 and 3/4l
21=7/4l
times 4 both sides
84=7l
divide by 7
12=l
sub
w=3/4l
w=3/4(12)
w=9
legnth=9
width=12
Answer:
x = -8, x = 5
Step-by-step explanation:
This can be solved using Factorization method:
Answer:
1. If you draw LMN in the first quadrant of the coordinate plane ( meaning if you draw where both x and y are positive), you will end up drawing L'M'N' in the third quadrant(where both x and y are negative) because the transformation rule of a 180° rotation is (x,y)→ (-x,-y). So for example, if L is (2,3), then, by the 180° rotation rule, L' would be (-2,-3) and that would apply to all the points.
2. When you draw a line through points L and L' or M and M' they create a straight line. In other words, they create a 180° angle. And yes, you would notice the same characteristic if you drew another line that goes through points N and N', and I know this because we use a 180° rotation, so it is going to create a 180° angle, which is a straight line. Another example is if we did a 90° rotation, when we connect points A and A' for example, it would create a 90° angle between the two points. So it's the same in this case but with a 180° rotation.
Step-by-step explanation: the explanation is on the answer.
