Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Cost of 5 - pound box of detergent = $3.50

Cost of 15 - pound box of detergent = $10.00

Number of loads can wash 5-pound box of detergent = 20

Number of loads can wash 15-pound box of detergent = 20\times 3=60

For 60 loads to be washed in 15 pound box of detergent costs $10.00

For 60 loads to be washed in 5 pound box of detergent costs

3.50\times 3\\\\=\$10.50

So, total saving while using 15 pound box of detergent is given by

10.50-10.00\\\\=\$0.50

So, total saving per load would be

\dfrac{0.50}{60}=\$0.008=0.8\ cents

Hence, option 'B' is correct.

Answer. Option  B. 0.8 cents.


Solution:

With a 5-pound box of detergent will wash 20 loads of laundry, then with a 15-pound box (5*3) of detergent will wash 20*3=60 loads of laundry, and you would pay $10.00.

To wash 60 loads of laundry with 5-pound box, you would need three 5-pound box, and you would pay $3.50*3=$10.50.


Then you would save in total $10.50-$10.00=$0.50

And per load, you would save: $0.50/60=$0.008=0.008*100 cents=0.8 cents

Kevin installed a certain brand of automatic garage door opener that utilizes a transmitter control with four independent​ switches, each one set on or off. The receiver​ (wired to the​ door) must be set with the same pattern as the transmitter. If six neighbors with the same type of opener set their switches​ independently.<u>The probability of at least one pair of neighbors using the same​ settings is 0.65633</u>

Step-by-step explanation:

<u>Step 1</u>

In the question it is given that

Automatic garage door opener utilizes a transmitter control with four independent​ switches

<u>So .the number of Combinations possible with the Transmitters </u>=

2*2*2*2= 16

<u> Step 2</u>

Probability of at least one pair of neighbors using the same settings = 1- Probability of All Neighbors using different settings.

= 1- 16*15*14*13*12*11/(16^6)

<u> Step 3</u>

Probability of at least one pair of neighbors using the same settings=

= 1- 0.343666

<u> Step 4</u>

<u>So the probability of at least </u>one pair of neighbors using the same settings

is  0.65633

Solve the equation. Show all of your work. 1/59X + 60) = 2/3x- 2
vivado [14]

Step-by-step explanation:

1/5x+60=2/3x-2

subtract 1/5x from 2/3x

when you do that you should get 0.46x repeating

then you add two to 60

you should get 62

62=0.46x

divide x

you get 134.7

Hii help I to lazy to do it
Oksanka [162]

Answer:

3 cans

Step-by-step explanation:

We need to find the area of the deck

A = 9 1/9 * 3

Changing to an improper fraction

9 1/9 = (9*9+1)/9 = 82/9

A = 82/9 *3 = 82/3

Changing back to  a mixed number

82/3 = 27  1/3

Each can covers 10 m^2

We will need 3 cans

The sum of 5 consecutive integers is 205. What is the third number?
Elza [17]
If 5 consecutive integers is 205,

then a + b + c + d + e = 205
 but also, each integer is separated  by a difference of 1

⇒  a + (a + 1) + (a + 2) + (a + 3) + (a + 4) = 205
⇒  5a + 10 = 205
⇒            5a = 195
⇒               a = 39

∴ third term = 39 + 2
                     = 41
