Answer:
The answer is 646 cm³.
Step-by-step explanation:
Firstly you have to seperate the solid into 2 shaoes, hemi-sphere and cube. Then calculate the volumes using the formula.
Given that the diameter of cube is 8cm so the radius is 8÷2 = 4cm :
Sphere,
Let r = 4 cm,
Cube,
Let length be 8cm,
Let width be 8 cm,
Let height be 8 cm,
Lastly, you have to add up both volumes together :
Answer:
9 kilometers
Step-by-step explanation:
.9 times 2 is 1.8. 1.8 times 5 is 9

Step-by-step explanation:
Answer: The number is 0.75 or 3/4
Step-by-step explanation:
let x = the number.
Now set up an equation: The product of a number (x) and -4 = -4x. So -4x is subtracted from the number - x. x-(-4x)
Then, that equals 3 more than the number (x) = x+3
So the equation is x-(-4x)=x+3.
Then, solve the equation!
x-(-4x)=x+3
x+4x=x+3 (Distribute the negative to the parentheses)
5x=x+3 (Combine like terms)
4x=3 (Get the Xs on one side by subtracting x from both sides)
x=0.75 or 3/4 (divide by the coefficiant, 4, on both sides)
