Mathematics

Answer:    49°, 49°, 82°

<u>Step-by-step explanation:</u>

Let x represent the base angles

then 2x - 16 is the vertex angle.

Triangle Sum Theorem states that the sum of the angles is 180°

(x) + (x) + (2x - 16) = 180

                 4x - 16 = 180

                       4x = 196

                         x = 49

Base angles: x = 49

Vertex angle: 2(49) - 16 = 82

if you stop at random in front of an animal exhibit,What is the probability that you will be looking at monkeys? I put the table
Mkey [24]

Answer:

1/10

step-by-step explanation:

----------------------------------

| animals | percent of animals |

----------------------------------

|    goats    |          16%           |

----------------------------------

|    camels    |          4%           |

----------------------------------

|    giraffes    |          6%            |

----------------------------------

|    llamas    |          6%           |

----------------------------------

|   deer    |          1%           |

----------------------------------

|   monkeys    |          10%           |

----------------------------------

|   birds    |          27%           |

----------------------------------

|   reptiles    |          14%           |

----------------------------------

|   bears    |          16%           |

----------------------------------

( sorry if the table above isnt 100% right or straight ^ )

first you add up all the percents of how much animals are in this exhibit

16 + 4 + 6 + 6 + 1 + 10 + 27 + 14 + 16

= 100 %

then since we are looking for the probability of stopping in front of the monkeys, we take that 100 we got earlier and get the 10% of monkeys from our table

10/100

but since there isnt a 10/100 on the answers we look for something that equals to 10/100 and 1/10 does since you can just times both the 1 and 10 to equal the 10 and 100 you were looking for

1/10

making 1/10 your answer!

hope this helps! and if you need anymore help on this math question just ask me :)

ms D ARRIVED AT SCHOOL AT 7:30 AM, SHE SPENT 35 MINUTES AT THE DINNER WITH A FRIEND IT TAKES HER 15 MINUTES TO GET TO SCHOOL WHA
Effectus [21]

Answer:

Ms D left at 6:40 AM

Step-by-step explanation:

Given:

MS D arrived at school at 7:30 AM

time spent for dinner = 35 mins

Time taken to to go to school = 15 mins

We will first find the Total time taken after leaving.

Total time taken can be calculated by adding time spent for dinner and Time taken to to go to school.

Total time taken after leaving = time spent for dinner + Time taken to to go to school = 35 +15 = 50 mins

MS D arrived at school at 7:30 AM.

Hence Time Ms D left  = Time She arrive at school - Total time taken after leaving = 7 hrs 30 min - 50 mins = 6 hrs 40 mins.

Hence Ms D left at 6:40 AM.
