Value of expression \frac{8}{2}(5) + (6-4) is 22 .

<u>Step-by-step explanation:</u>

Here we have the following expression to solve :

8÷2*5+(6-4)

⇒ (8/2)*5 + (6-4)

⇒ \frac{8}{2}(5) + (6-4)

But 8 = 4(2) , So

⇒ \frac{4(2)}{2}(5) + (6-4)

⇒ 4(5) + (6-4)

⇒ 20 + (6-4)

⇒ 20 + 2

⇒ 22

Therefore, Value of expression \frac{8}{2}(5) + (6-4) is 22 .

The value of y varies directly with x. If x = 3, then y = 22. What is the value of x when y equals 105
Nutka1998 [239]

Answer:

Varies directly uses the formula: y/x = k

22/3 = 7.33

105/x = 7.33

105/x (7.33/x) = 7.33(x/7.33)

105/7.33 = x

x = 14.32

Dubnium-262 has a half-life of 34 s. How long will it take for 500.0 grams to
dmitriy555 [2]

Answer:

the time taken for the radioactive element to decay to 1 g is 304.8 s.

Step-by-step explanation:

Given;

half-life of the given Dubnium = 34 s

initial mass of the given Dubnium, m₀ = 500 grams

final mass of the element, mf = 1 g

The time taken for the radioactive element to decay to its final mass is calculated as follows;

1 = 500 (0.5)^{\frac{t}{34}} \\\\\frac{1}{500} =  (0.5)^{\frac{t}{34}}\\\\log(\frac{1}{500}) = log [(0.5)^{\frac{t}{34}}]\\\\log(\frac{1}{500})  = \frac{t}{34} log(0.5)\\\\-2.699 = \frac{t}{34} (-0.301)\\\\t = \frac{2.699 \times 34}{0.301} \\\\t = 304.8 \ s

Therefore, the time taken for the radioactive element to decay to 1 g is 304.8 s.
