Answer: 10 inches
Explanation: You are given one side of the aquarium which is 18 inches. The top and the bottom of the aquarium is 18 inches because that’s what the diagram gives us. So you can multiply 18 x 2=36. Now, to find the missing side length, subtract the perimeter (56 inches) by 36 and you get 20 inches. However, that’s not your final answer because you have to divide 20/2=10 inches. 10 inches is the missing side length for the left and right side lengths.

Step-by-step explanation:
Given : A certain stretch of West Street, I claim that most cars are going more than 5 miles per hour (mph) over the speed limit.
The speed limit is posted at 25 mph.
In a random sample of 70 cars, 46 of them were traveling faster than 30 mph (25+5).
Number of cars going more than 5 mph over the speed limit=46
Then, the sample proportion of cars going more than 5 mph over the speed limit will be :_
Hence, the sample proportion of cars going more than 5 mph over the speed limit =
Answer:
(3)》》》60°
Step-by-step explanation:
Since the exterior angle of a triangle is
equal to the sum of non-adjacent interior angles, we have
<DAB=<ABC +<BCA
》180-3x =(6x-40) + (x+20)
》180-31 - 3t sx-not x+20
》180-3x - 72-20
》7x+3x= 180+20
》10x=200
》x=20°
(Being complementory angles)
<DAB+ <BAC = 180°
》180-3×20°+<BAC=180
》<BAC=60°
