40% of the number 50 is 20
Answer:
option D
Step-by-step explanation:
Take the two through which the lines passes.
Let it be ( -5 , 0) and ( 0 , -3)
Step 1 : Find slope, m


Step 2 : Find the equation

3(3) - (-8)/4 = 9 + 2 = 11 so (3,-8) is solution
3(4) - 4/4 = 12 - 1 = 11 so (4,4) is solution
answer
C. both ordered airs are solutions
We need to divide the number of inches by the number of hours.
Let's first convert the two numbers into fractions.
12 1/2 = 25/2
25 1/2 = 51/2
(25/2) / (51/2) = 25/2 * 2/51 = 50/102 = 25/51 = 0.49
The average rainfall was approximately 0.5 inches per hour.
A triangle interior angles add up to 180
so we have 3:4:5
the ratio of the angles
3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees
