Answer:
Distance between the observer and the red car is
Step-by-step explanation:
Diameter of field = 500 m
Radius of field =
Let R be the radius and the speed at which the car completes race be w
So,
Car finished 5 laps in minutes = 30
Car finished 1 lap in minutes =
So,
Refer the attached figure
Angle between car and observer = wt
So, Distance between the observer and the red car is give as A sin wt
So, Distance between the observer and the red car=
Answer:
w = 1.6
Step-by-step explanation:
Given w varies inversely as then the equation relating them is
w = ← k is the constant of variation
To find k use the condition when x = 4, w = 4
k = w = 4 × = 4 × 2 = 8
w = ← equation of variation
When x = 25, then
w = = = 1.6
Answer:
Step-by-step explanation:
7.5/100= .075
$580000 x .075 = $43,500 commission
Answer:
Exact form : x=6/5
Decimal form : x=1.2
Mixed Number form : x=1 1/5
Step-by-step explanation: Solve for x by simplifying both sides of he equation, then isolating the variable.

Explanation:
The standard form for a linear equation is
A
x
B
y
=C
, where
A
,
B
,
and
C
are numbers, and
x
and
y
are variables.
y
=
