The general equation for any circle with its center at point (a, b) is
(x - a)² + (y - b)² = (radius)²
So the circle in the question is centered at (-3, -4), and its radius is 3 .
Answer:
40 min is the answer
Step-by-step explanation:
To solve this we need to convert all the units into SI units
for ritu,
speed= 90km/hr
= 90 × 1km/ 1hour
= 90×1000/3600 m/s
= 25m/s
distance = 120×1000m
time = distance/ speed
= 120000/25
= 4800sec
= 4800/60min
= 80 min
for garima,
distance =120×1000m
speed = 60km/hr
= 60×1000/3600 m/s
=100/6 m/
time = 120000/(100÷6)
= 7200sec
= 7200÷60 min
= 120 min
time difference is 120-80 = 40 min
They spent a total of $46.25
Here's how I got my answer:
Step 1: Add $18.00 and $16.40 together. Which is $34.50.
Step 2: Add $34.50 and $11.75, which will give you your answer, $46.25.
P = 2L + 2W
factor out 2 from right side
P = 2(L+W)
Divide both sides by 2
P/2 = L + W
subtract W from both sides
L = P/2 - W
