2/3 x + 15 = 17
2/3 x = 17 - 15
2/3 x = 2
x = 2 / (2/3)
2/1 * 3/2 = 6/2 = 3
x = 3

So
2\3x+15=17 FIRST SUBTRACT 15 FROM BOTH SIDES!!!!
   -15=-15 =15 AND -15 CANCEL EACH OTHER AND 17-15=2
2\3x=2    THEN DIVIDE BOTH SIDE BY 2\3x
÷2\3x=÷2\3x 2\3 = 0.6666667
   2\3x and 2\3x cancel each other and 2\0.6666667 = 0.33333333

Answer would be rounded to nearest tenths

Step-by-step explanation:

i cannot find an answer from the expression but i can guess if you didnt follow pemdas, it would be d

3.5 × 102 is 357

(8 × 10−4) + (6 × 10−4) is 132

132/357= .369 or .37 or 0 simplified

d is 4*10-10

10-10 is 0

The propeller blades on a submarine have a radius of 6 feet. At full speed, they turn at 120 revolutions per minute. What is the

bogdanovich [222]

Using proportions, it is found that the angular velocity at the tip of the blade is of 753.98 radians per minute.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Each revolution has $2\pi$ radians, hence in one minute, the 120 revolutions will have a measure in radians of:

M = 120 x 2pi = 240pi = 753.98

Hence the angular velocity is of 753.98 radians per minute.

On October 15, 2019, Jon purchased and placed in service a used car. The purchase price was $38,000. This was the only business

san4es73 [151]

Answer:

cost recovery deduction = $1520

Step-by-step explanation:

given data

purchase price = $38,000

used the car business = 80%

used the car personal = 20%

solution

cost recovery limit are

cost recovery limit = asset value × statutory % × mid quater convention ..........1

we know car which have 5 year MACRS convention and as per MACRS depreciated 20 % in 1st year

and here this car is use so no 1st year depreciation

so we use MACRS statutory % method

cost recovery limit = $38000 × 5%

cost recovery limit = $1900

we know maximum limit is $3160

so cost of recovery is $1900

cost recovery deduction is

cost recovery deduction = cost recovery limit - personal use

cost recovery deduction = $1900 - ( $1900 × 20% )

cost recovery deduction = $1520

Answer:

36.58% probability that one of the devices fail

Step-by-step explanation:

For each device, there are only two possible outcomes. Either it fails, or it does not fail. The probability of a device failling is independent of other devices. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
