Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 7}}}}}$

Step-by-step explanation:

Let the number be 'x'

Create an equation

$\sf{ {x}^{2} = 49}$

Squaring on both sides

$\dashrightarrow{ \sf{ \sqrt{ {x}^{2} } = \sqrt{49} }}$

$\dashrightarrow {\sf{ \: x = 7}}$

Hope I helped!

Best regards!

Answer:

x= 7

Step-by-step explanation:

Let the unknown number be x

${x}^{2} = 49$

Square root both sides

$\sqrt{ {x}^{2} } = \sqrt{49}$

Simplify

$x = 7$

Answer: The area is approximately 314 ft^2

Step-by-step explanation:

Well if the diameter is 20 feet then the radius will be 10 because the radius is half the diameter, and to find the area of a circle, you use the formula

A= $\pi r^{2}$ where A is the area and pi times the radius squared.

We will represent pi by 3.14

A= 3.14* 10^2

A= 3.14 * 100

A = 314

liberstina [14]

Answer:

16.34 hours

Step-by-step explanation:

According to the given information we can see that the case is of exponential growth

Hence, we will use the formula

$A=P(2)^\frac{t}{24}$

Here A =800 is the amount that is needed to reach

P is the initial amount that is 500

We have to find the time it will take to reach 800 that is we need to find t

On substituting the values in the formula we get

$800=500(2)^\frac{t}{24}$

On simplification we get

$\Rightarrow\frac{8}{5}=(2)^\frac{t}{24}$

Taking log on both sides we get

$\Rightarrow\log\frac{8}{5}=\log(2)^\frac{t}{24}$

using $\log\frac{m}{n}=\log m-\log n$

And $\log a^m=m\log a$

$\Rightarrow\log{8}-\log{5}=\frac{t}{24}\log2$

Now substituting values of log 8=0.903, log 5=0.698 and log 2=0.301 we get

$\Rightarrow 0.903-0.698=\frac{t}{24}0.301$

$\Rightarrow 0.205=\frac{t}{24}0.301$

$\Rightarrow \frac{0.205}{0.301}\cdot 24=t$

$\Rightarrow t=16.34$
