Answer:
Volume of cone = 40 in³
Step-by-step explanation:
Given:
Volume of cylinder = 120 in³
Height of cylinder = Height of cone
Radius of cylinder = Radius of cone
Find:
Volume of cone
Computation:
Volume of cylinder = πr²h = 120 in³
Volume of cone = (1/3)πr²h
So,
Volume of cone = (1/3)(120)
Volume of cone = 40 in³
Answer:
3 2/3
Step-by-step explanation:
To do this question, you would need to multiply 7 1/3 with 1/2. The answer is 3 2/3.
solution: Mr. Schwartz will need to order more wheels after building 12 cars.
explanation:
Mr. Schwartz begins with total number of wheels = 85
he has to order more wheels once he left with less than 40 wheels
so min. no. of wheels he can use before ordering more wheels = 85-40 = 45
Mr. Schwartz uses 4 wheels to build 1 car
Mr. Schwartz uses 45 wheels to build 45÷4 = 11.25 cars
then, if he builds 12 cars then he needs 12×4 = 48 wheels
total supply of wheels he begins with = 85
wheels he used to build 12 cars = 48
so total number of wheels remaining are = 85-48 = 37
since 37 is less than 40 so after building 12 cars Mr. Schwartz need to order more wheels.
Use the rules of indices
When they are dividing we subtract the exponents provided the bases are the same.
Since the bases are the same,
(2/3)^5 ÷ (2/3)¹
Will be
(2/3)^5-1
= (2/3)⁴
= 16/81
Hope this helps.
