Below 40 0.27 0.73
Above 40 0.57 0.43
Work: 8+22=30 17+13=30 turn into a fraction then simplify to get answer;
22/30 simp= 73.0 (0.73)
13/30 simp= 43.0 (0.43)
8/30 simp= 26.667 (0.27)
17/30 simp= 56.667 (0.57)
The lengths of adjacent sides of the parallelogram are 40 cm and 50 cm.
<h3>What is a parallelogram?</h3>
A parallelogram is a simple quadrilateral with two pairs of parallel sides.
Now, suppose a and be are two sides of parallelogram
Then, Perimeter P = 2( a+ b)
Now, it is given that perimeter of a parallelogram is 180 cm.
⇒ 2( a+ b) = 180
⇒ a + b = 90
It is also given that one side exceeds the other by 10 cm.
⇒ a = b + 10
Putting the value of a in above equation we get,
b + 10 + b = 90
⇒ 2b = 90 - 10
⇒ 2b = 80
⇒ b = 40 cm
Similarly, a = b + 10
⇒ a = 40 + 10
⇒ a = 50 cm
Hence, the required sides of parallelogram are 40cm and 50cm.

I'm guessing that they took of in the same airport.
Each hour they will separate by 1260 miles or 21 miles each minute
2,000/21 = 95.23 minutes which is 1 hour and 35 minutes
Hope this helps :)
Answer:
B and D
Step-by-step explanation:
Write as a quadratic
-2x² - 3x + 5 = 0
Factor
-2x² - 5x + 2x + 5 = 0
-x(2x + 5) + 1(2x + 5) = 0
(1 - x)(2x + 5) = 0
To make the equation 0, x is either 1 or -5/2.
Answer: C. domain: {9, 10, 11, 12); range: (22, 32, 41, 30)
Step-by-step explanation:
The data set is:
(9, 22)
(10,32)
(11, 41)
(12, 30).
In the usual notation, the number at the left is the input (belons to the domain) and the number in the right is the output (belongs to the range).
Then the domain would be:
{9, 10, 11, 12}
and the range:
{22, 32, 41, 30}
The correct option is C
