irakobra [83]

Answer:

5/36

Step-by-step explanation:

Total number in the universe = 4 + 3 + 5 = 12
Probability of selecting a green (first time) = 4/12
Probability of selecting a yellow (2nd time) = 5/12
P(gr then yellow) = 4/12 * 5/12 = 20 / 144
This reduces to 5/36

The speed limit on highways in Florida is 70 miles per hour write and solve an inequality to find how long it will take to trave

Nata [24]

Answer:

The time is less than or equal to 1.5 hours

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x -----> the time in hours

The inequality that represent this situation is equal to

$\frac{105}{x}\leq 70$

Solve for x

Multiply by x both sides

$105 \leq 70x$

Divide by 70 both sides

$105/70 \leq x$

Rewrite the inequality

$x \geq 105/70$

$x \geq 1.5\ hours$

therefore

The time is less than or equal to 1.5 hours

A snow cone cup at the County Fair is 15 cm tall and has a diameter of 8 cm. If the cup is filled just to the top, what is the v

Alja [10]

We have been given that a snow cone cup at the County Fair is 15 cm tall and has a diameter of 8 cm. We are asked to find the volume of the cup.

We will use volume of cone formula to solve our given problem.

$V=\frac{\pi r^2h}{3}$ , where,

h = Height of cone,

r = Radius of cone.

We know that radius is half the diameter, so radius of given cone would be half of 8 cm that is $\frac{8}{2}=4$ cm.

Upon substituting our given values in above formula, we will get:

$V=\frac{3.14\times (\text{4 cm})^2\times \text{ 15 cm}}{3}$

$V=3.14\times 16 \text{ cm}^2\times \text{5 cm}$

$V=251.2\text{ cm}^3$

Therefore, the volume of cup is 251.2 cubic cm.
