Answer: 1, 1&1/4, 3/2, 1&6/8
The answer is 15 hours.
I used division to answer this question:
There are 4 elephants and 30 hour: 
So: divided by 2 is 
So it takes 15 hours for 2 elephants to set up a tent.
Answer:
Mode 66
Step-by-step explanation:
The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!
We have a triangle:
the side opposite the angle Ф is 4/5,
The side adjacent the angle Ф is 3/5
1) we calculate the hypotenuse, by the Pythagoras Theorem:
h=√[(4/5)²+(3/5)²]=1
2) we calculate the csc of Ф
csc Ф= hypotenuse / opposite side
csc Ф=1/ (4/5)=5/4
Answer: e. 5/4
Y= 2x + 9
The slope is 6/3 which is simplified to 2. The intercept is 9.
