Depth: 7/2 feet
Rate: 5/4 feet per hour

Time = depth / rate of filling
Time = 7/2  /  5/4
Time = 14/5
Time = 2 4/5 hours

Rate :  1 1/4 ft per hour = 5/4 ft per hour
Depth :  3 1/2 = 7/2 ft
7/2 : 5/4 = 7/2 * 4/5 = 28/10 = 14/5 = 2  4/5
Answer:

1/20 - 3/12 + 6/35

3/60 - 15/60 + 6/35

In the accompanying diagram of ABC ca is extended to D, m∠ABC = 70 and m∠BCA =50 Find m∠DAB
zvonat [6]

Answer:

<em>120 degrees</em>

Step-by-step explanation:

Find the diagram attached.

From the diagram;

Interior angles are m∠BCA and m∠ABC

Exterior angle is m∠DAB

The sum of interior angle of the triangle is equal to exterior

m∠BCA +m∠ABC =m∠DAB

Given

m∠ABC = 70

m∠BCA =50

m∠DAB = 70 + 50

m∠DAB = 120 degrees

<em>Hence the measure of m∠DAB is 120 degrees</em>

REAAAALLLLY NEED HELP
pashok25 [27]
If you think about it, the question is asking us to find the greatest common factor, or GCF, of the two numbers, 24 and 18. 
First, find all of the factors of 24. 
The factors are: 1, 2, 3, 4, 6, 8, 12, 24 
Next, find the factors of 18.
The factors are: 1, 2, 3, 6, 9, 18 
List out all of the factors that both of the numbers have. 
The factors are: 1, 2, 3, 6
Whichever is the greatest of these numbers is the GCF. 
The GCF is 6, so the greatest number of groups he can make and still be able to win is 6. 
Hope this helps!
