Answer: Rita's paddling speed in still water is 2.5 miles pet hour and the speed of the river's current is 0.5 miles per hour.
Step-by-step explanation:
Let x represent Rita's paddling speed in still water.
Let y represent the speed of the river's current.
On a canoe trip, Rita paddled upstream (against the current) at an average speed of 2 miles per hour relative to the riverbank. This means that
x - y = 2 - - - - - - - - - - - - -1
On the return trip downstream (with the current) . Her average speed was 3 miles per hour. This means that
x + y = 3 - - - - - - - - - - - - -2
Adding equation 1 and equation 2, it becomes
2x = 5
x = 5/2 = 2.5 miles per hour.
Substituting x = 2.5 into equation 1, it becomes
2.5 - y = 2
y = 2.5 - 2 = 0.5 miles per hour
1) The triangles are congruent by SSS.
The two tick marks indicate two pairs of congruent sides; it is evident that the third side is congruent by the way the diagram is drawn - the bases of the triangles are together and appear to be the same length.
2) The triangles are congruent by SAS.
The two pairs of tick marks indicate congruent sides, and their included angles are congruent because they are vertical angles, and vertical angles are always congruent.
Answer:
With new regime is 183,750Rs
Step-by-step explanation:
I. 75,000 * 13 [12 months + 1 month bonus] = 975,000
II. Ms.Gurung tax rate will be ₹37500 + 15%
III. Perform ratio x/975,000 = 15/100 [15% is 15/100] = 146,250
IIII. ₹37500 + 146,250 = 183,750Rs
It depends on how tax rate will costs, could be more or less.
Answer:
slope form = y= 3/4x -7
point slope= y-(-3) = 3/4(x-3) or y-(-4)= 3/4(x-4)
Step-by-step explanation:
slope form = y= mx + b
y = 3/4x - 7
point-slope form = y - y1 = m(x - x1)
step 1. Substitute a convenient value of x into your equation and solve for y (You're doing this to get the point x1,y1). Let's choose x=3. Yes, you could choose x=4.
y= 3/4x - 7
if you choose x = 3
y=3/4(3) - 7
y = 4 -7
y = -3
(x1,y1) = (3,-3)
if you choose x = 4l
y= 3/4(4) - 7
y = 3 - 7
y = -4
(x1,y1)= (4, -4)
step 2. Substitute the point you found , (x1, y1) , into the point slope formula.
if you choose x=3
y-y1=m(x-x1)
y-(-3) = 3/4(x- 3)
if you choose x = 4
y- y1 = m(x-x1)
y - (-4) = 3/4(x-4)
