There are many ways to solve number 5 as it is just an reduce/enlargement of equidistant fractions
The first method that came up to my mind is just dividing denominators.
For A) you can do 72 divided by 18 which would give you 4. Then you can divide the given numerator with the answer you got from dividing the denominators. This would be 8 divided by 4 which would give you two. This means that 2/18 is equal to 8/72. You can check by simplifying the fraction. Both 2/18 and 8/72 equal 9 when simplified, therefore correct.
You can use this method for b, either use a calculator because of the decimals or just remove the decimals and replace them later. Make sure when you use this method, you are always dividing the bigger number. So in B you would do 40.3 divided by 12.4
Answer:
1152
Step-by-step explanation:
Multiply 3200 * 0.045
144 * 8=1152
Answer: 6 feet
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cone= (1/3) π radius² height
Replacing with the values given and solving for r:
36π = (1/3) π r² 12
36π/ [(1/3) π 12]= r²
9 = r²
√9 =r
3 ft = r
Since:
Diameter = 2 x radius
Substituting r=3
D = 2x 3
D = 6 feet
Feel free to ask for more if needed or if you did not understand something.
You don’t have to worry about the t subtract 3 and 9
