Answer:
Step-by-step explanation:
Given
Number of service bays
Time taken by each bay to finish one oil change
Working capacity hours per day
Thus, in hours the total number of times one bay has changed the oil is equal to
If one service bay's capacity is equal to , capacity of two service bays is equal to
Thus, the design capacity is
Answer:
What grade is this.
Step-by-step explanation:
The value of x is -2 and the value of y is -1.
Step-by-step explanation:
Step 1; The given equations are taken as
-3y -9x =21 or -9x -3y = 21, take this as equation 1
-18x +4y =32, take this as equation 2
Step 2; We multiply equation 1 with 2 and equation 2 with 1 so we can cancel out the variable x in both equations. By doing this we get
-18x -6y =42, take this as equation 3
-18x +4y =32, this is the same as equation 2
If we subtract 3 with 2, we cancel out the x variable and can calculate the value of y.
10y = -10 , y = -10/10 = -1
Step 3; Substituting this value of y in any of the previous equations we will get x's value. Here this value of y is substituted in equation 2.
-18x +4(-1) =32, -18x -4 = 32 , -18x = 36, x=-2.
So we have x = -2 and y = -1.
PQ shows the height of the triangle from its base
As P is the highest point of the triangle
and Q lies on the base of the triangle
So PQ is the height of the triangle
And the height of any triangle is also known as the altitude of the triangle
So
PQ is nothing but the Altitude of this triangle
So option D is correct
Altitude
