Answer:
Step-by-step explanation:
Subtract b from both sides.
Divide both sides by a.
B
70^2 -30^2=5184
square root answer to get 72
C lies on AB
True
BA is a ray on plane P
A ray passes through the plane. In this case, the line is on the plane, not passing through. So it is not a ray.
AB + BC = AC
True.
X, Y and Z are colinear
Colinear points are part of the same line. In this question, there is no line passing through these points, so they are not colinear.
W, A and Y are coplanar:
Coplanar points are on the same plane. In this item, points A and Y are on the same plane. However, point W is not, so they are not coplanar.
Answer:
12 meters
Step-by-step explanation:
The area of a parallelogram can be found using:
a=bh
We know that the base is 7 meters, and the area is 84 square meters. Therefore, we can substitute 7 in for b, and 84 in for a.
84=7h
We want to find the height. To do this, we have to get h by itself. Since h is being multiplied by 7, divide both sides by 7.
84/7=7h/7
12=h
So, the height is 12 meters
Answer:
4/7
Step-by-step explanation:
1/4 divided by 7/16 is the same thing as 1/4 * 16/7. Multiply this and you will get the fraction of 16/28. Once simplified, this comes out to be 4/7.
