If all the dogs weighed the same, 44 would be the mean. The weight would be 44*5=220.
Hope this helped☺☺
Let a = Adult tickets, s = Student tickets; we are going to set up a system of equations.
8a + 4s = 880
a - s = 20
We are going to multiply the second equation by so that we can cancel out one of the variables and solve for the other. This gives you:
8a + 4s = 880
4a - 4s = 20
Notice the s-variables will cancel:
12a = 900
a = 75
Now we plug in the amount of adult tickets to solve for the student ones.
75 - s = 20
- s = - 55
Divide both sides by - 1
s = 55.
There were 55 student tickets sold and 75 adult tickets.
Answer with Step-by-step explanation:
We are given that a point (3,1,0)
Two vectors are
A=<1,1,0>
B=<0,1,1>
Let v
Substitute the values then we get
The parametric equation of the line
Using the formula
The parametric equation of the line which is passing through the point (3,1,0) and perpendicular to both i+j and j+k is given by
The symmetric equation of the line is given by
Using the formula
The symmetric equation of the line which is passing through the point (3,1,0) and perpendicular to both i+j and j+k is given by
Answer:
Y = MX
Step-by-step explanation:
If two quantities X and Y maintain a proportional relationship with each other, then we can write this as Y ∝ X.
Now, converting this relation into the equation we write Y = MX ........ (1), where M is a constant.
Now, from the above equation, we can say that the rate of change of Y with respect to the unit change of X is always constant.
Graphically. this equation represents the graph of a straight line with a constant slope and passing through the origin. (Answer)
