Answer:

Option C. The volume of the sphere is equal to 904\ ft^{3}

Step-by-step explanation:

we know that

The Volume of a sphere is equal to

V=\frac{4}{3}\pi r^{3}

In this problem

we have

r=6\ ft

assume

\pi =3.14

substitute

V=\frac{4}{3}\pi (6^{3})=904\ ft^{3}

A 5 divided by 48 lottery involves choosing 5 of the numbers from 1 through 48 and a 4 divided by 35 lottery involves choosing 4
Anika [276]

Answer:

4/35 lottery is easier to win.

Step-by-step explanation:

For the 5/48 lottery, the winning probability is \frac{5}{48} ≈0.1042

For the 4/35 lottery, the winning probability is \frac{4}{35} ≈ 0.1143

Since \frac{4}{35}  >  \frac{5}{48} , the lottery where one chooses 4 of the numbers 1 through 35 is easier to win.

Kenny had 5/7 more trading cards than lee. After Kenny collected 50% more trading cards, he had 220 more trading cards than lee.
svp [43]

Answer:

Step-by-step explanation:

Let X is the number of cards Kenny has

Let Y is the number of cards Lee has

1. Kenny had 5/7 more trading cards than lee, it means

X = Y + 5/7X (1)

2. After Kenny collected 50% more trading cards, he had 220 more trading cards than lee, it means:

X + 50%X = Y +  220 (2)

So, we solve the 2 equations to find out X and Y

\left \{ {{X=Y + 5/7X} \atop {1.5X=Y +220}} \right.

<=> X = \frac{3080}{17} and Y = \frac{880}{17}

<=> X ≈181 and Y ≈ 52
