Answer:
OD = 9.375"
Step-by-step explanation:
We can draw a line from O to B to create a triangle.
Then, Triangle ODB and Triangle ACB are similar, so their corresponding side's ratio are similar as well.
Triangle ACB, we can use pythagorean theorem to figure out CB:
AC^2 + CB^2 = AB^2
15^2 + CB^2 = 17^2
225 + CB^2 = 289
CB^2 = 64
CB = 8
Now relating the corresponding sides, we can figure out OD:

 
        
             
        
        
        
Answer:
8gallons 
Step-by-step explanation:
If Joe drinks 10 liters of water every week, then;
10liters = 1 week
After 3weeks;
x litres =3 weeks
Divide both expressions
10/x = 1/3
x = 3*10
x = 30litres
This means he consumes 30litres in 3 weeks
If there are approximately 19 liters in 5 gallons, the;
19litres = 5gallons
To determine the number of gallons consumed in 3 weeks;
30litres = y
Divide both expressions
19/30 = 5/y
Cross multiply
19 * y = 30*5
19y = 150
y = 150/19
y = 7.89
y ≈ 8 (to nearest whole number)
Hence Joe drinks 8gallons of water in 3weeks
 
        
             
        
        
        
Answer:
10x2= 20 -7 =13  :answer is 10.
Step-by-step explanation:
 
        
                    
             
        
        
        
Point-slope formula;
y - y1 = m(x - x1)        given point(-1, 4) and slope(m) is 4.
y - 4 = 4(x - (-1)
y - 4 = 4x + 4
y = 4x + 4 + 4
y = 4x + 8               << the equation.
hope this helped, God bless!
