Answer:
55 square feet jsjjjis the answer
Answer:
756π cm^3.
Step-by-step explanation:
Volume of the cone
270π = 1/3 π r^2 h
270π = 1/3 π r^2 * 10
r^2 = 270 / ( 10/3 )
r^2 = 81
r = 9 cm.
So the volume of the hemisphere = 1/2 * 4/3 * π * 9^3
= 486π cm^3.
So the volume of the whole solid = 270π + 486π
= 756 π cm^3.
The answer is The Multiplication or Division Principle of Equality. It states that if you multiply or divide both sides of an equation by an expression, the resulting the equation will be equivalent to the original equation.
14x = 56
x = 4 <-- Divide both sides by 14
So, x is equal to 4.<span />
x = hours
car 1 left an hour before car 2 so you have 55(x+1)
car 2 = 75x
add them together to equal miles driven:
55(x+1) + 75x = 380
55x+55 + 75x = 380
combine like terms:
130x+55 = 380
subtract 55 from each side:
130x = 325
divide both sides by 130
x = 325 /130 = 2.5
x = 2.5 hours
so 2.5 hours
Answer:
D. 3x + 1 < x + 3
Step-by-step explanation:
Assuming the number to be x
Three times a number = 3x
1 more than 3 times a number = 1 + 3x
The symbol for less than is = <
The sum of 3 and the same number = x + 3
After assembling the given data, the equation will be:
3x + 1 < x + 3
[The options given in the question are incorrect. The correct options will be:
A. 3x + 1 = x + 3
B. 3x − 1 = x + 3
C. 3x − 1 > x + 3
D. 3x + 1 < x + 3 ]
∴ Option D is the correct answer.
