Rate in walk = 2 miles/hr
Distance by walk = x
Rate in jog = 4 miles/hr
Distance by jog = y
Total distance = 3.4
Total time = 1.2 hours
x + y = 3.4
x/2 + y/4 = 1.2
if we multiply by 4
2x + y = 4.8
Subtract both equations
x = 1.4 miles
y = 2 miles
walking time = 1.4/2
= 0.7 hour
walking distance = 1.4 miles
jogging time = 2/4
= 0.5 hour
jogging distance = 2 miles
Y = -2x + 9 is your answer!
God bless!
Answer:
2 or maybe 1
Step-by-step explanation:
there is angle then side (line) and then another angle.
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
You can solve for sides of a triangle using the following equation.
A = arccos (b^2 + c^2 - a^2/2bc)
And likewise for other variables by moving the letters.
Ultimately, in this problem you get the following angle measures:
15.87
23.97
140.16
