Answer:
378 marbles are blue, and 270 marbles are red
Step-by-step explanation:
The total number of ratio units must be multiplied by 6 to get the total number of marbles. Hence the number of blue marbles is 63×6 = 378, and the number of red marbles is 45×6 = 270.
Answer:
C) Neither
Step-by-step explanation:
y = -1/4x + 8
-2x + 8y = 4
To compare the slopes we need to convert the second equation to the same form as the first ( that is slope/intercept form).
-2x + 8y = 4
8y = 2x + 4
Divide through by 8:-
y = 1/4 x + 1/2
The slope of the first line is -1/4 and its 1/4 for the second line.
If the slopes were the same the lines would be parallel and if they were perpendicular their product would be = -1.
The product is 1/4 * -1/4 = -1/16
So they are neither parallel nor perpendicular.
The volume of the cylinder will be equal to 1017.87 cubic feet.
<h3>What is volume?</h3>
Volume is defined as the space occupied by any object in the three-Dimensions. For the cylinder, the volume will be calculated by radius and the height of the cylinder.
Given that:-
- A cylinder has a base radius of 9 feet and a height of 4 feet.
The volume of the cylinder will be calculated by using the formulas below:-
V = πr²h
V = π ( 9 )² 4
V = 1017.87 cubic feet.
Therefore the volume of the cylinder will be equal to 1017.87 cubic feet.
