In this question the main information's are already provided. Based on them the answer to the question can be easily deduced.
Let us assume the width of the poster = x
Then the length of the rectangle = 3x
The perimeter of the rectangle = 24 inches
we already know
Perimeter = 2 ( Length + width)
24 = 2( 3x + x)
24 = 2 * 4x
24 = 8x
x = 24/8
= 3
So the width of the rectangle is 3 inches
Length of the rectangle = 3x
= 3 * 3
= 9
So the length of the rectangle is 9 inches.
Answer:
1/2
Step-by-step explanation:
<span>The correct answer is option C i.e. RS is the straight line and plane is RSU. Because both the points R and S are on a straight line , so the line is RS. And, there are two conditions for a plane to form: 1) Three non-collinear points, as R, S and U do not lie on the same line so they are non-collinear. And 2) A straight line and a point that does nt lie on the staright line. Here, the straight line is RS and the point is U.</span>
Step-by-step explanation:
8×9 = 72 (too big)
8×8 = 64 (too small)
so, the answer for 70/8 = x is between 8 and 9.
therefore, D is the right answer option.
2 points on the best fit line are (1.5, 2.5) and (9.5, 20)
from these 2 points
gradient,m = (20- 2.5)/(9.5 - 1.5)
m = 2.19
using y = mx +c for any of the 2 points
...c = -0.78
thus solving for y at x = 11...the best answer is 23.5
