Answers

2(4Y-1)=6
8Y-2=6
8Y=6+2
8Y=8
Y=8/8=1

Answer: y=1
2(4y-1) = 6

simplify

8y-2 = 6

+2 to both sides

8y = 8

/8 to both sides

y=1

Tina Cole is a certified financial adviser. She purchased equipment for her office for $8,843. The trade-in value of the equipment is estimated to be $450 after 7 years of use. Using the straight-line method, what is the annual depreciation to the nearest cent?

Answers

Straight - line method allows the determination of the annual depreciation by dividing the total reduction in property value by the number of years. In the given above, The total depreciation of the value is $8,393. Dividing this value by 7 years gives $1,199/year. 

Therefore, the annual depreciation is $1,199.0

Answer:

$1,199 per year.

Step-by-step explanation:

Tina Cole is a certified financial adviser.

She purchased equipment for her office costs = $8,843

After 7 years of use the trade-in value of the equipment is estimated = $450

Total depreciation in 7 years = 8,843 - 450 = $8,393

We have to calculate the annual depreciation using the straight-line method.

So we divide $8,393 by 7

$8,393 ÷ 7 = $1,199

The annual depreciation of the equipment is $1,199 per year.

180 ÷ 2 = 90; 90 ÷ 2 = 45 ; 45 ÷ 3 = 15 ; 15 ÷ 3 = 5 ; 5 ÷ 5 = 1 => 180 = (2^2) * (3^2) * 5 => √(180) = 2*3 * √(5 )=6 √(5)  ;

In the same way we have √(245)=7 √(5)  ; and √(320 )=8 √(5)  ;

Finally, 6 √(5)+7 √(5)  - 8 √(5) = 13 √(5) - 8 √(5) =7 √(5).

A coin was flipped 150 times. The results of the experiment are shown in the following table:Heads Tails
90 60


Which of the following best describes the experimental probability of getting heads?
It is 10% higher than the theoretical probability.
It is 10% lower than the theoretical probability.
It is equal to the theoretical probability for this data.
The experimental probability cannot be concluded from the data in the table.

Answers

Answer:

The statement that best describes the experimental probability of getting heads is:

       It is 10% higher than the theoretical probability.

Step-by-step explanation:

We know that the theoretical probability of getting head is: 0.5

and the theoretical probability of getting tail is: 0.5

Also, the results of experiments are:

          Heads        Tails

           90                60

This means that the experimental probability of getting head is: 90/150=3/5=0.6

and the experimental probability of getting tail is: 60/150=2/5=0.4

Hence, the experimental and theoretical probability of getting head is not same or equal.

Also, the experimental probability of getting head is more than the theoretical probability  of getting head and the percent increase is calculated as:

(0.6-0.5)* 100\n\n\n=(0.1)* 100\n\n=10\%

Answer:

Its 10% higher than theoretical

Step-by-step explanation:

90/150 x 100= 60%

60-50=10

Approximately how long is a leg of an isosceles right triangle that has a hypotenuse of length 14.14 cm? A. 3 cm B. 5 cm C. 7 cm D. 10 cm

Answers

According to the fact that isosceles right triangle with the hypotenuse of 14.14 cm its cathetus should be 9.998 cm, and if we round this number we will get 10 cm. Therefore, the answer is D. 10 cm.
