Answer:
60 1/4
Step-by-step explanation:
x-1/4=60
x=60+1/4
x=60 1/4
Answer:
1) 
2) 
3) 
Step-by-step explanation:
General form of sin function is
Where A is Amplitude
B is 
C is Mid line
1) Given : A sine function has the following key features
Frequency = 
Period is 
Amplitude= 2
Mid line y= 2
Y intercept (0,2)
This function is NOT a reflection of its parent function of the x-axis
Solution : We put the value in the general form of sin function
A= 2 , 
, C=2
2) Given : A sine function has the following key features
Period = 4
Amplitude = 3
Mid line y = -1
Y intercept (0,-1)
Solution : We put the value in the general form of sin function
A= 3 , 
, C=-1
3) Given : A sine function has the following key features
Period = 
Amplitude = 2
Mid line y = -12
Y intercept (0,-2)
Solution : We put the value in the general form of sin function
A= 2 , 
, C=-2
Answer:
60
Step-by-step explanation:
12 can be broken into 3*4
15 = 5*3
The least factors are
3*4*5 = 60
The lowest common denominator is 60
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators
Answer: 12 minutes
Step-by-step explanation:
This is a standard Work Formula question (2 or more 'entities' that work on a task together). When there are just 2 entities and there are no 'twists' to the question, we can use the Work Formula to get to the correct answer.
Work = (A)(B)/(A+B) where A and B are the individual times needed to complete the task.
We're told that two hoses take 20 minutes and 30 minutes, respectively, to fill a pool. We're asked how long it takes the two hoses, working together, to fill the pool.
(20)(30)/(20+30) = 600/50 = 12 minutes to fill the pool.
