Answer:
r = 20
Step-by-step explanation:
-4 = r/20 - 5
-4 + 5 = r/20 - 5 + 5
1 = r/20
1 * 20 = r/20 * 20
r = 20
Answer:
B. 77
Step-by-step explanation:
7 + x = 84
Subtract 7 from both sides
x = 77
The missing value x=3 is obtained by the concept of slope in coordinate geometry.
<h3>What is slope?</h3>
Positive or negative rates of change are both possible. Since the slope of a line is determined by the ratio of the vertical and horizontal change between any two locations on a plane or line, the slope is determined by the rise to run ratio. Where, Rise is the difference in elevation between two points. The horizontal shift between two places is known as a run.
Formula of slope =
(equation 1)
According to the question the coordinates are: xi=2, x2=x, y1=6, y2=10
Given, rate of change=4 (here rate of change=slope)
Putting all coordinates in equation 1
Slope=
4=4/x-2
x-2=1
x=3
Therefore, the missing value x=3

The correct answer to this is “True”.
Symmetry signifies balance and form. An object with
rotational symmetry will still look the same after a rotation. Since it maintains
its shape and figure after being rotated, therefore its characteristics such as
length of the diagonals, the angles of each corner, or parallelism of opposite
sides will remain the same.
Answer:
Step-by-step explanation:
1/9 of the camp means it has 9 parts the whole thing (each 1/9)
1/3 of an hour for 1 part and
for 9 parts we have
1/3 *9 = 9/3= 3 hours
