In a box containing a dozen eggs ,3 eggs are rotten .What fraction of eggs are not rotten?

Minchanka [31]

Answer:

3/4 of the eggs are not rotten.

Step-by-step explanation:

a dozen = 12 eggs

3+3+3+3 = 12

3x4 = 12

1/4 = 3/12

2/4 = 6/12

3/4 = 9/12 <--- |

4/4 = 12/12 |

12-3 = 9 ---------|

SO 3/4 eggs are not rotten

M is the incenter of triangle ABC. Find the lengths of MD and DC. (Look at pic)

Deffense [45]

Answer:

Part 1) $MD=9\ units$

Part 2) $DC=12\ units$

Step-by-step explanation:

Step 1

Find the length of MD

we know that

The incenter is the intersection of the angle bisectors of the three vertices of the triangle. Is the point forming the origin of a circle inscribed inside the triangle

In this problem

$MD=ME=MF$ ------> is the radius of a circle inscribed inside the triangle

we have that

$MF=9\ units$

therefore

$ME=9\ units$

$MD=9\ units$

Step 2

Find the length of DC

we know that

In the right triangle MDC

Applying the Pythagoras theorem

$MC^{2} =MD^{2}+DC^{2}$

we have

$MD=9\ units$

$MC=15\ units$

substitute

$15^{2} =9^{2}+DC^{2}$

$DC^{2}=225-81$

$DC=\sqrt{144}\ units$

$DC=12\ units$

What is -4/9*(-7/9)?

seropon [69]

Hello! So both numbers are negative, so the answer will definitely be positive. All you have to do is multiple straight across. 4 * 7 is 28 and 9 * 9 is 81. That’ll make the fraction 28/81. The product is 28/81.
