Answer:
A
Step-by-step explanation:
Perpendicular bisector of a line divides the line into 2 equal parts and it is perpendicular to the line.
First let's find the midpoint of CD. The point is where the perpendicular bisector will cut through the line.
midpoint= 
Thus, midpoint of CD

Gradient of line CD

The product of the gradients of perpendicular lines is -1.
gradient if perpendicular bisector(1)= -1
gradient of perpendicular bisector= -1
y=mx +c, where m is the gradient and c is the y-intercept.
y= -x +c
Subst a coordinate to find c.
<em>Since the perpendicular bisector passes through the point (8, -10):</em>
When x=8, y= -10,
-10= -8 +c
c= -10 +8
c= -2
Thus, the equation of the perpendicular bisector is y= -x -2.
Answer:
Each of the 7 large animals ate 71 lbs of food.
Step-by-step explanation:
There was a total of 680 lbs of food, and the elephant ate 183 lbs by itself. This means that there was 497 lbs of food left for the 7 large animals. To find out how much food each of the 7 animals ate, we just divide. 497 lbs of food divided by 7 large animals. This will give us a final result of 71 lbs of food per large animal.
I cannot see the mass of the moon, can you comment the two masses so I can explain?
Answer:
17.9 units is the answer
Step-by-step explanation:
points are (-7,-2) and (9,6)
Pythagorean theorem can be written as,

Rounding off,
d = 17.9 units
The answer to the problem is as follows:
<span>So each thing separate by a positive, negative, multiplication or division sign. so here it would be 8h is one term and 15t is the second term so there are two.
