Step-by-step explanation:
Coefficients before x and y should be equal to coefficients before x1 and y1 on every equation of lines that are parallel to the given line
General formula for them should be y-5x=b where b is every number we want.
So one of them could be y-5x=0 or y-5x=2 ...
Answer:
A = 58 degrees
b = 51.9
c = 48.5
Step-by-step explanation:
To find A we simply just need to remember that all triangles add up to 180 degrees and we are already given two angles of the triangle so....
To find sides b and c we use the law of sines since we now know the angle of each side.
Hope this helps.
I would say 75 feet per hour, though I am not 100% sure.
I first found the difference between hours (6-2 = 4) and then found the difference between distance (700 - 400 = 300). I then divided distance by hours and got 75.
Answer:
5 bags of cement are required.
Step-by-step explanation:
Since to make concrete, the ratio of cement to sand is 1: 3, if cement and sand are sold in bags of equal mass, to determine how many bags of cement are required to make concrete using 15 bags of sand the following calculation must be done:
Cement = 1
Sand = 3
3 = 15
1 = X
15/3 = X
5 = X
Therefore, 5 bags of cement are required.
