This is the concept of algebra, let the original length of the hexagon be x, after the dilation the length became x×7/5=7/5x
the perimeter of the original figure is:
6*x=6x
The perimeter of the enlarged on is:
6*7/5x=8.4x
therefore the perimeter of the new compared to the old will be:
8.4x/6x
=1.4
the new perimeter is 1.4 times the old perimeter
Answer:
8.33%
Step-by-step explanation:
Given that the quiz has;
A multiple-choice question with 3 possible answers
A multiple-choice question with 4 possible answers
In the first question;
⇒The three choices,each has the probability of 1/3 to be picked
In the second question;
⇒The four choices, each has a probability of 1/4 to be picked
1/4
Finding the probability that both responses are correct will be;
1/3* 1/4 =1/12
As a percentage will be
1/12 * 100= 8.33%
8 + 2(10 - r) = 8 + 20 - 2r = 28 - 2r
the 2 answers are AB and DE
Angle 4 is the same as angle 6, 75 degrees, there are alternate interior angles.
