Represent as an equation;
Expand the above
<em>Recall that b = $10 ----given</em>
becomes
First we need to find Mia's speed (v) in km/min
v = distance travelled/ time
v = 3 km/20 minutes
v = 0.15 km /min
in order to convert the speed into mile/min, we need to use the conversion factor given in which for every kilometer, there is 0.6 miles.
v = 0.15 km/min *(0.6 miles/ km)
v =0.09 miles/min
therefore the speed in miles/min is 0.09 miles/min
Option B is the correct answer
Step-by-step explanation:
Step 1 :
Given,
Maximum budget Sandra has for the trip is $90
Fixed rental fee = $30
Daily fee = $10
Step 2 :
Let x be the number of the days for which Sandra can go for the trip
If the daily fee is $10, the cost for x number of days would be 10*x
the fixed fee is $30
So the equation is represent the cost of the trip is 30 + 10 x
given that the maximum budget is $90, the above cost should always be less $90
So the required inequality is 30 + 10x ≤ 90
Option B is the correct answer
Answer:
Third option: 5.48
Step-by-step explanation:
Given the quadratic model that represents the approximate height in meters of the ball 
. the time in seconds x, when the ball is 50 meters from the ground can be calculated by substituting 
and solving for x.
Then:
Subtract 200 from both sides:
Divide both sides by -5:
Apply square root to both sides:
The ball is 50 meters from the ground after about 5.48 seconds.
