Answer:
Step-by-step explanation:
let the length of rectangle=l units
width=9
p=2(l+9)
area=9l
9l=2(l+9)
9l=2l+18
7l=18
l=18/7 units
Answer: C) 
Step-by-step explanation:
Given : The equation for this investment is B = 500(1.13)t, where B represents the balance and t is the number of years.
For monthly interest , Rate = 
Time = 12 t [ 1 year = 12 months ]
As r = 0.13 , so rate = 
Now, the equation will be :


Correct option : C) 
Answer:
15√2 (fourth answer choice)
Step-by-step explanation:
Note that the ratio 15/x is the tangent of 30 degrees, which in turn is 0.577 or 1/√2. Then:
1/√2 = 15/x, or
1 5
----- = ----- or x = 15√2
√2 x
Answer:
I believe the answer would be 4,5,6.
Step-by-step explanation:
Answer:
d= 106° e= 51° f= 59°
Step-by-step explanation:
d= 106° because it is an alternate interior angle (z angle)
e=51° because it is an alternate interior angle (z angle)
f= 59° because it is a corresponding angle ( F angle)
