Answer:

Step-by-step explanation:

Since 10x4=40, and 14x4=56, then all you have to do is multiply 3 by 4, to get 12.

Answer:

Step-by-step explanation:

If given figures are similar, then corresponding sides are in proportion.

Therefore we have the equation:

$\dfrac{x}{3}=\dfrac{56}{14}$ <em>cross multiply</em>

$(14)(x)=(3)(56)$

$14x=168$ <em>divide both sides by 14</em>

$\dfrac{14x}{14}=\dfrac{168}{14}$

$x=12$

Element X decays radioactively with a half life of 13 minutes. If there are 530 grams of Element X, how long, to the nearest ten

Leona [35]

Answer:

$t \approx 50.4\,min$

Step-by-step explanation:

The time constant of the element X is:

$\tau = \frac{13\,min}{\ln 2}$

$\tau = 18.755\,min$

The decay function has the following form:

$\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }$

$t = -\tau \cdot \ln \frac{m}{m_{o}}$

$t = -(13\,min)\cdot \ln \left(\frac{11\,g}{530\,g} \right)$

$t \approx 50.4\,min$

Suppose that in one week in November in St. Louis, the temperature dropped by an average of 4 degrees every day. The temperature

victus00 [196]

Answer:

Step-by-step explanation:

<u>Linear Modeling</u>

The temperature in St. Louis dropped by 4 degrees every day in one week.

When d days have passed, the temperature will have dropped by 4d degrees.

We know the temperature t at the beginning of the week was 65 degrees.

Thus, when d days pass, the linear model for the temperature t is:

t = 65 - 4d

Write two irrational numbers between 1/5 and 2/5

Marina CMI [18]

Answer:

Step-by-step explanation:

First make all the fractions into decimals

1/5 = 0.2

2/5 = 0.4

As we know non terminating numbers are irrational so make up any non terminating number between 0.2 and 0.4

Like 0.3454672438700894......

Or 0.27435847454706.....
