What is 7/6 reduced to

Answers

7/6 is 1 and 1/6 (1 1/6) as a reduced fraction. 7/6 is an improper fraction. So, how many times does 6 go into 7, it goes into it one time and there is one remainder.

Answer:

1 1/6

Step-by-step explanation:

7/6 is an improper fraction, so to reduce it, you know that 6/6+1/6=7/6. 6/6=1, and 1/6 is still just 1/6. When you put the two together, you get 1 1/6

What is the volume of a cone with a radius of 18 cm and a height of 10 cm? Use 3.14 for pi. Round your answer to the nearest tenth. (4 points) 3275.4 cm3 3540.8 cm3 4000.2 cm3 3391.2 cm3 Previous Next

Answers

Answer: 3391.2\text{ cm}^3

Step-by-step explanation:

The volume of cone is given by :-

V=(1)/(3)\pi r^2 h, where r is radius and h is height of the cone.

Given: Radius = 18 cm

Height : 10 cm

Then , the volume of the cone will be :-

V=(1)/(3)(3.14) (18)^2 (10)=3391.2\text{ cm}^3

Hence, the volume of the cone = 3391.2\text{ cm}^3
I hope this helps you




Volume of Cone = 1/3.pi.r^2.h



Volume=1/3.3,14.18^2.10


Volume=10173,6/3


Volume=3391,2

George plans to purchase a new scooter for $8000 and to keep it until it is worth a fourth of its original price. The value of the scooter is give by V = 8000( 1 8 )t, where V is the value of the scooter and t is the number of years that have passed. If George finds that he can buy the scooter on sale for $6895, how should he change the value equation? A) Replace the 8000 with 6895. B) Replace the 8000 with 1 6 . C) Replace the 1 8 with 6895. D) Replace the 1 8 with -6895.

Answers

Answer:

A) Replace the 8000 with 6895

Step-by-step explanation:

The given function is

V=8000((1)/(8)) t

Where V is the value of the scooter and t is the number of years.

According to the problem, George plans to purchase new scooter for $8000. That means the number 8000 in the given function refers to the price of the scooter. So, if he finds that the scooter costs $6895, then we should replace $8000 with $6895.

Therefore, the right answer is A.
