how to solve, A reservoir is 3 1/4 miles wide. Tony sails 4/5 the width of the reservoir. About how far did Tony sail?

1 answer:

6 0

Well, how much is 4/5 of 3 and 1/4? well, is just their product, thus, firstly, let's change the mixed fraction to "improper" and proceed,

$\bf \stackrel{mixed}{3\frac{1}{4}}\implies \cfrac{3\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{13}{4}}\\\\
-------------------------------\\\\
\cfrac{4}{5}\cdot \cfrac{13}{4}\implies \cfrac{13}{5}\implies 2\frac{3}{5}$

Complete question :

Compute the probability of each of the following events.

Event : The sum is greater than 6

Event : The sum is not divisible by 2

Answer:

7/12 ; 1/2

Step-by-step explanation:

Sample space :

2, 3, 4, 5, 6, 7

3, 4, 5, 6, 7, 8

4, 5, 6, 7, 8, 9

5, 6, 7, 8, 9, 10

6, 7, 8, 9, 10, 11

7, 8, 9, 10, 11, 12

Probability that sum is greater than 6:

Number of outcomes greater Than 6 = required outcomes = (7,7,7,7,7,7,8,8,8,8,8,9,9,9,9,10,10,10,11,11,12) = 21

Total sample space = total possible outcomes = 36

Probability = required outcome / Total possible outcomes

P(sum is greater Than 6) = 21 / 36

2.)

Obtaining an even number :

Sum not divisible by 2 = required outcomes = (3, 5, 7, 3, 5, 7, 5, 7, 9, 5, 7, 9, 7, 9, 11, 7, 9, 11) = 18

Total sample space = total possible outcomes = 36

P(sum is not divisible by 2) = 18 / 36 = 1 / 2

In a certain clothing store, 6 shirts and 3 ties cost $79.50, and 3 shirts and 2 ties cost $41. Determine the cost of each shirt

Pepsi [2]

Answer: $12

Step-by-step explanation:

For this problem, we can use system of equations to solve. Let's use x for shirts and y for ties.

Equation 1

6x+3y=79.5

This equation comes from the first sentence. 79.5 is the total cost.

Equation 2

3x+2y=41

This equation comes from the second part of the first sentence. 41 is the total cost.

Since we are looking for the cost of each shirt, let's use the elimination method to eliminate y. First, we need to multiply both equations to that the y in both equations equal each other.

2(6x+3y=79.5)

3(3x+2y=41)

Now that we have chosen a common number, we can multiply.

12x+6y=159

9x+6y=123

We can now subtract both equations to cancel out y.

3x=36

Divide to get x alone.

x=12

Each shirt costs $12.
