Answer:
Perimeter: 16x + 16
Area: 40x + 15
Step-by-step explanation:
Remember, the perimeter is the sum of all the sides of a figure, it can be found by adding up all the sides. The area is the space within the figure, in the case of a quadrilateral can be found by multiplying the length by the width. Finally, in a rectangle, the opposite sides are congruent, parallel, and intersect in 90degree (right) angles.
Using this,
1. Find the perimeter
Since opposite sides are congruent, there will be two sides with a measure of ( 8x + 3 ), and two sides with the measure of 5. Hence the sum of all the sides would be
8x + 3 + 8x + 3 + 5 + 5
Add them together,
16x + 16.
The perimeter of the figure is 16x + 16
2. Find the area,
To find the area of a rectangle, multiply the length by the width.;
( 8x + 3 ) * 5
Distribute:
40x + 15
The area of the figure is 40x + 15
Answer:
X=13
Step-by-step explanation:
First I squared 12 and 5 and got 144 and 25 then I added them which was a total of 169 then I took the square root of 169 and got x=13.
Since the unit rate of Tito is greater than that of Jonah, hence T<u>ito is running at a faster rate</u>
<h3>Unit rates</h3>
The ratio of distance covered by an object to tme taken is unit rate.
Calculate the unit rate for both Jonah and Tito
For Jonah
Unit rate = 5laps/9minutes
Unit rate = 0.56 laps per minute
For Tito
Unit rate = 7laps/11.2minutes
Unit rate = 0.625laps per minute
Since the unit rate of Tito is greater than that of Jonah, hence T<u>ito is running at a faster rate</u>

Answer:
0.97725
Step-by-step explanation:
Given that Professor Heinz has given the same multiple-choice final exam in his Principles of Microeconomics class for many years. After examining his records from the past 10 years, he finds that the scores have a mean of 76 and a standard deviation of 12.
i.e.
Std error of mean = sigma/sqrt n = 2
Thus the sample mean is N(76,2)
Required probability = probability that a class of 36 students will have an average greater than 72 on Professor Heinz's final exam.
