The expression 7•3x is not equal to the expression 21x. You might think that the two expressions are the same since 7x3 is 21 but the first expression is a dot product. This kind of expression includes the magnitude and direction of the vector in an expression, for example, <span>7•3x. The second expression, 21x, expresses only the magnitude and does not include the direction.</span>
ANSWER: Total marbles =56 Number of groups =8 Therefore number of marbles in each group =56/8 = 7 marbles in each group. HOPE IT HELPS!!!! PLEASE MARK BRAINLIEST !!!!
The amount of soil that the pot can hold is best approximated by calculating for the volume of the cylinder through the equation, V = πr²h We first calculate for the radius, r, given the circumference, C C = 2πr; r = C/2π = 66 in/2(π) = 10.5 in Then, substituting the known values. V = π(10.5 in)²(30 in) V = 10,390.81 in³ Thus, the volume of the soil is approximately 10,400. The answer is the third set.
