Answer:
ratio of regular to diet soda = 16/9
Step-by-step explanation:
Jessica brought a cooler to the family picnic filled with 32 cans of regular soda and 18 cans of diet soda. This means
Number of cans of regular soda = 32
Number of cans of diet soda = 18
Total number of soda brought to the family picnic = number of cans of regular soda + number of cans of diet soda
= 32 + 18= 50
the ratio of regular soda cans to diet cans in the cooler= 32/18
Divide numerator and demo minator by 2, we have 16/9.
The fraction cannot be reduced further. So ration of regular to diet soda = 16/9

Answer: perimeter = 96mm, Area = 564mm².
Step-by-step explanation:
From the diagram, it is a trapezium, it has a rectangle joined together by a right angled triangle. Now to find the perimeter, we add all the dimensions together. To get the other side of the rectangle, which is also the perpendicular height of the figure, we take the Pythagoras. Let the perpendicular height = x
Therefore,
25² = ײ + 7²
625 = x² + 49
x² = 625 - 49
x² = 576
x. = √576
= 24.
Now the perimeter
= 20 + 25 + 7 + 20 + 24
= 96mm.
Area of the figure will be
= 1/2( a + b )h
Where a = 20, b = 20 + 7 = 27 and h = 24, now substitute for the values
( 20 + 27) x 24
---------------------
2
= 47 x 24/2
= 47 x 12
= 564mm²
