Answer:
12, 6 and 30
Step-by-step explanation:
Step one:
given data
Number of medals = 48 medals
The given ratio is = 2:1:5
The total ratio is = 2+1+5= 8
Step two;
Applying the part to all method
for Gold we have
2/8=x//48
cross multiply
8x= 48*2
divide both sides by 8
x= 96/8
x= 12
gold is 12
for silver we have
1/8=x//48
cross multiply
8x= 48*1
divide both sides by 8
x= 48/8
x= 6
silver is 6
for bronze we have
5/8=x/48
cross multiply
8x= 48*5
divide both sides by 8
x= 240/8
x= 30
Bronze is 30

The answer to the question is 3 8/33
Answer:
Could be C) or D) None of these, 29688.05cm^2
Step-by-step explanation:
Did the question to round off to any numbers?
Formula for cylinder's T.S.A: 2 π r h + 2 π r^2
Diameter= 2 x radius
Radius = 70cm / 2 = 35cm
Height -> need to convert m to cm -> 100cm
Substitute these values into the formula:
2 x π x 35 x 100 + 2 x π x (35)^2 = 29688.05cm^2
Answer:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.
