The sample and h is the half-life, in days, of the substance. A sample contains 60% of its original amount of Fermium-257. The half-life of Fermium-257 is about 100 days. About how old is the sample? 52 days 60 days 74 days 136 days

Answers

Answer:

74 days

Step-by-step explanation:

The computation is shown below;

The proportion that remains left after d days is

p = (1/2)^(d ÷ 100)

In the case when the proportion is 60%

So,  

0.60 = 0.50^(d ÷ 100)

Now

log(.60) = (d ÷ 100)log(.50)

100·log(.60) ÷ log(.50) = d = 74 days

6.) Resuelve: 6(X + 8) - 30 + 7 = 49​

Answers

Answer:

x=4

Step-by-step explanation:

6(x+8)-30+7=49

6x+48-30+7=49

6x=49-48+30-7

6x=1+23

6x=24

x=[tex]\frac{24}{6}[/tex]

x=4

Step-by-step explanation:

Para resolver esto yo use una app llamada m a t h w a y

(sin los espacios) esta puede estar en varios idiomas, aunque esto se modifica segun el idioma en donde la uses.

6(x+8) -30+7 = 49                           1. Simplifica 6(x+8) -30+7

6x+25 = 49                                     2. Mueve todos los términos que no

                                                   contengan x al lado derecho de la ecuación

6x = 24                                           (25 pasa restando por lo cual sería, 49-25

                                                       que es igual a 24.)

                                                       3. Divide cada término por 6 y simplifica.

x = 4

12. What type of triangle is shown? ​

Answers

Answer:

Scalene triangle, right triangle.

Step-by-step explanation:

To find out what type of triangle this is, we have to find x, so we set up an equation:

The sum of interior angles in a triangle add up to 180°

(2x + 15°) + (4x - 10°) + (x) = 180°

Open paranthesis:

2x + 15° + 4x - 10° + x = 180°

Combine like terms:

7x +  5° = 180°

Same to both sides

7x = 175°

x = 25°

We plug in x for each of the values:

2(25°) + 15° = 65°

4(25°) - 10° = 90°

25° = 25°

Because none of the angles are equal, that makes this triangle a scalene triangle, and since one of the angles is a 90° angle, that makes this triangle a right triangle

I hope this helped, let me know if you have any questions.

A store is having a sale on walnuts and chocolate chips. For 2 pounds of walnuts and 3 pounds of chocolate chps, the total cost is $16. For 6 pounds of walnuts
and 5 pounds of chocolate chips, the total cost is $34. Find the cost for each pound of walnuts and each pound of chocolate chips.

Answers

Answer:

1 lb of chips cost $3.50

1 lb of walnuts cost $2.75

Step-by-step explanation:

c = $ chips

w = $ walnuts

System of Equations:

2w + 3c = 16

6w + 5c = 34

I multiplied the first equation by -3 to eliminate the 'w' terms to get

c = 3.5

I substituted 3.5 for 'c' to get 2.75 for 'w'

At Pizza Pi, 12% of the pizzas made last week had extra cheese. If 6 pizzas had extra cheese, how many pizzas in all were made last week?

Answers

Answer:

50? maybe

Step-by-step explanation:

since half of the percentage was made it would also fall in for the other 88%.

im not 100% sure tho

The total number of pizzas is given as 50.

What is percentage?

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

The percent value of pizzas having extra cheese is given as 12%.

Suppose the pizzas made last week be x.

Then, as per the question the following equation can be written as,

⇒ 12% × x = 6

⇒ 12/100x = 6

⇒ x = 50

Hence, the number of pizzas that were made last week is given as 50.
