Answer:
Step-by-step explanation:
By creating a common denominator, you can compare different numbers to the same ratio. For example:
Take 2/3 and 3/4
Now 3/4 is the same as 9/12
And 2/3 is the same as 8/12
Now that they have the same denominator, you can tell that 9/12 is clearly greater than 8/12, meaning 3/4 is greater than 2/3.
Answer:
The value of the car is 0.94 times the value of the car the previous year.
Step-by-step explanation:
To tell if JKON and JKLM are similar, compare the ratios between corresponding sides. For example:
JK / KO = 5/8
JK / KL = 5/22
The ratios aren't the same, so the shapes aren't similar.
The radius of the completed cone is
... 18×(300°/360°) = 15
The height of the completed cone is found from the Pythagorean theorem:
... 15² + h² = 18²
... h = √99 = 3√11
The volume is given by
... V = (1/3)πr²·h = (1/3)π·15²·3√11
Dividing this value by π gives 225√11 cubic units.
