-268/21
First you multiply 22 times 1/3 which will give you 22 1/3 then you make it into a mixed number by multiplying the bottom number of the fraction with the whole number and then adding it with the top number of the fraction in this case is (22*3)+1 then you multiply fractions normally by multiplying the top and bottom numbers with each other In this case would be -4*67 and 3*7 and the you get your answer (simplify if necessary)
Answer:
The answer is B. 20in.
Step-by-step explanation:
The parallel sides have to be the two bases (b1 and b2) = 80in.
h = height or altitude.
h = 2(800)/b1+b2
h = 1600/80
h = 20 in.
The speed of the snake is 8.95 miles per hour.
Step-by-step explanation:
Step 1:
The snake travels at a speed of 20 meters in 5 seconds.
We will need to determine the distance it covered in a single second. To do that we divide the distance covered in 5 seconds by 5.
The distance covered in 1 second
So the snake is moving at a distance of 4 meters per second.
Step 2:
To convert the speed of the snake from meters per second to miles per hour, we multiply the speed in meters per second by 2.23694.
So to attain 4 meters per second in miles per hour, we multiply it by 2.23694.
4 meters per second miles per hour.
Rounding this off, we get the speed of the snake as 8.95 miles per hour.
