Answer:
Yes, parallelogram OABC is a rectangle.
Step-by-step explanation:
The vertices of a parallelogram are O(0,0), A(-4,1), B(-3,5) and C(1,4).
A parallelogram is a rectangle if its any two adjacent sides are perpendicular to each other.
product of slopes of two perpendicular lines is -1.
Formula for slope is
Using the formula we get
It means OA is perpendicular to AB.
Since two adjacent sides are perpendicular, therefore the given parallelogram OABC is a rectangle.
Answer:
48 + 48 solve it and that is your answer
The height of the kite will be 6.6 ft rounded to the nearest tenth.
<u><em>Explanation</em></u>
According to the below diagram, AB is the height of the kite and AC is the 12 ft line attached to it.
The line is pulled taut and casts a 10 ft shadow. That means BC = 10 ft
Now, in right angle triangle ABC, using <u>Pythagorean theorem</u>....

So, the height of the kite will be 6.6 ft rounded to the nearest tenth.
Answer:
w = -19
Step-by-step explanation:
Move the 6w to the left and 7 to the right.
4w-6w=31+7
Combine like terms
-2w=38
Divide by negative 2.
w=-19
Answer:
0.34
Step-by-step explanation:
iff we think of them all as a percentage then it looks like
25% + 17% + 21% + 3%
then you add them to get 66%
now you know you are missing 34% to make up the rest of the area.
