What is the missing length

Zina [86]

Answer:

c = 12

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

$7.2^{2} + 9.6^{2} = c^{2}$

51.84 + 92.16 = $c^{2}$

144 = $c^{2}$

$\sqrt{144}$ = c

12 = c

Jermaine did this work to solve an equation. Did he make an error?

Tanya [424]

Answer:

First, I go by finding <em>x</em><em> </em>and <em>r</em>.

After that, put the numbers (ie. x= # and r=#) into the equations. Check it by finding L.H.S and R.H.S. (ie. left hand side and right hand side)

If you are still confused, comment down and I'll try to provide better explanation!

Bezzdna [24]

Given:

First customer bought 1/2 of all eggs of lady seller and 1/2 of an egg.

Her second customer bought 1/2 of all the remaining eggs and 1/2 of an egg.

At this point she had sold all her eggs.

To find:

The number of egg the lady have when she came to the market.

Solution:

Let x be the number of egg that the lady have when she came to the market.

First customer bought 1/2 of all eggs of lady seller and 1/2 of an egg. So, the number of remaining eggs after first customer is

$x-\dfrac{1}{2}x-\dfrac{1}{2}=\dfrac{x}{2}-\dfrac{1}{2}$

Her second customer bought 1/2 of all the remaining eggs and 1/2 of an egg. So, the number of remining egg after second customer is

$\text{Remaining eggs}=\dfrac{x}{2}-\dfrac{1}{2}-(\dfrac{x}{2}-\dfrac{1}{2})\times \dfrac{1}{2}-\dfrac{1}{2}$

$=\dfrac{x}{2}-\dfrac{1}{2}-\dfrac{x}{4}+\dfrac{1}{4}-\dfrac{1}{2}$

$=(\dfrac{x}{2}-\dfrac{x}{4})+(-\dfrac{1}{2}+\dfrac{1}{4}-\dfrac{1}{2})$

$=(\dfrac{2x-x}{4})+(\dfrac{-2+1-2}{4})$

$=\dfrac{x}{4}-\dfrac{3}{4}$

At this point she had sold all her eggs. It means the remining eggs is 0.

$\dfrac{x}{4}-\dfrac{3}{4}=0$

$\dfrac{x}{4}=\dfrac{3}{4}$

Multiply both sides by 4.

$x=3$

Therefore, the lady came to the market is with 3 eggs.

The circumference of a circle is 30t. What is its area?

labwork [276]

Answer:

$A=\frac{225t^2}{\pi}$ given the circumference is 30t.

Step-by-step explanation:

The circumference of a circle is $C=2\pi r$ and the area of a circle is $A=\pi r^2$ assuming the radius is $r$ for the circle in question.

We are given the circumference of our circle is $2 \pi r=30t$ .

If we solve this for r we get: $r=\frac{30t}{2\pi}$ . To get this I just divided both sides by $2\pi$ since this was the thing being multiplied to $r$ .

So now the area is $A=\pi r^2=\pi (\frac{30t}{2 \pi})^2$ .

Simplifying this:

$A=\pi (\frac{30t}{2 \pi})^2$ .

30/2=15 so:

$A=\pi (\frac{15t}{\pi})^2$ .

Squaring the numerator and the denominator:

$A=\pi (\frac{(15t)^2}{(\pi)^2}$

Using law of exponents or seeing that a factor of $\pi$ cancels:

$A=\frac{(15t)^2}{\pi}$

$A=\frac{15^2t^2}{\pi}$

$A=\frac{225t^2}{\pi}$
