The length of an object in feet is equal to three times its length in yards. The length of a waterslide is 48 feet. Write and pick equation to find the length of a waterslide in yards

Answers

Answer:

Equation is: $L=3y$

Length in yards is 16 yards.

Step-by-step explanation:

Let 'L' represent length in feet and 'y' in yards.

Given:

Length of the waterslide is, $L=48\ ft$

Length in feet is three time its length in yards. Therefore,

Length in feet = 3 $*$ Length in yards.

∴ $L=3y$

Dividing both sides by 3, we get:

$(L)/(3)=(3y)/(3)\n\ny=(L)/(3)$

Now, plug in 48 for 'L' and solve for 'y'. This gives,

$y=(48)/(3)\n\ny=16\ yards$

Therefore, the length of the waterslide of length 48 feet in yards is 16 yards.

An ice chest contains cans of apple juice, cans of grape juice, cans of orange juice, and cans of mango juice. Suppose that you reach into the container and randomly select three cans in succession. Find the probability of selecting three cans of juice.

Answers

Answer:

4.9%

Step-by-step explanation:

This question is incomplete. However; it can be found on search engines. The complete question is as follows :

An ice chest contains cans of six apple juice, eight cans of grape juice, four cans of orange juice, and two cans of mango juice. Suppose that you reach into the container and randomly select three cans in succession. Find the probability of selecting three cans of grape juice.

Solution :

In an ice chest there are different cans of juice. Among them

Number of cans of apple juice = 6

Number of cans of grape juice = 8

Number of cans of orange juice = 4

Number of cans of mango juice = 2

Total number of cans of juice = 6 + 8 + 4 + 2 = 20

Let A, B and C are the event of selecting of three cans. The events A, B and C are dependent.

Probability of selecting three cans of juice

P = $\frac{\text{number of grape cans}}{\text {total number of cans}}$
