Solve for x.<br><br> 3(3x - 1) + 2(3 - x) = 0

olganol [36]

Use distributive property to get rid of the parenthesis.....

9x - 3 + 6 - 2x = 0
combine like terms
7x + 3 = 0
move the 3 over by subtraction
7x = -3
divide by 7
x = -3/7

Tennis balls are sold in cylindrical cans with the balls stacked one on top of the other. A tennis ball has a diameter of 6.7 cm

andrey2020 [161]

Answer:

629.92 $cm^3$

Step-by-step explanation:

The minimum volume of the can that can hold 4 tennis balls must have at least the same volume as 4 tennis balls.

The volume of one tennis ball, V = $\frac{4}{3}\pi r^3$

where r = radius of the tennis ball

The diameter of a ball = 6.7 cm

Its radius will be = 6.7 / 2 = 3.35 cm

Volume, V, will be:

$V = \frac{4}{3}\pi (3.35)^3$

V = 157.48 $cm^3$

Hence, the volume of 4 balls will be:

4 * V = 4 * 157.48 = 629.92 $cm^3$

The minimum volume that the cylindrical can has to have is 629.92 $cm^3$ .

Robin rolled a die and then flipped a coin. What is the probability she rolled an even number and the coin landed on heads?

aleksandr82 [10.1K]

Answer:

1/4

Step-by-step explanation:

There are 3 even numbers of the 6 numbers on a die.

(1,2,3,4,5,6) are the possible numbers. 2,4,6 are even

P( even number ) = 3/6 = 1/2

P (heads) = 1/2

Since they are independent events, we can multiply the probabilities together

P (even, heads) = 1/2 * 1/2 = 1/4
