12(0.57)= 6.84
10-6.84= 3.16
Mr. Turner’s change is $3.16.
Hope this helps!
Answer:
<h2>50h miles</h2>
Step-by-step explanation:
For us to write a math expression for the problem, we will use the formula for calculating speed.
Speed is the change of distance of a body with respect to time.
Mathematically, Speed = Distance/Time
Distance = Speed * Time
If Lumpy drove for h hours at 50 mph, then Lumpy speed = 50mph and time = h hours.
Substituting the given parameters into the formula to get the distance;
Distance = 50mph * h hours
Distance = 50h miles
<em>Hence the math expression that modeled how far Lumpy drive is 50h miles</em>
Answer:
3x²y+0.5y+1
Step-by-step explanation:
2+3x²y -0.5y+y -1
2 and -1 is 1
-0.5y and +y is +0.5y so the answer is...
Answer:
Linear relationship always produces a straight line and are without exponential.
Lets check all the given options:
1. the total area, in square meters, y, of a square garden if the side length is x meters.
The area of a square is
Here, side is 'x' and area 'y' will be .
This is not linear.
2. the height, y, of a 6-foot tree that grows 0.2 feet per month for x months
The equation forms:
When x = 1
When x = 2
=>
When x = 3
=>
This is a linear relation.
3. the total cost, y, of a ski rental from a company that charges $15 plus an additional $8 per day rented for x days
The equation forms:
When x = 1
When x = 2
=>
When x = 3
=>
This is also linear.
4. the total miles, y, traveled by a car going 62 miles per hour in x hours
The equation forms:
When x = 1
When x = 2
=>
When y = 3
=>
This is also linear in nature.
