Answer:
Step-by-step explanation:
We have to write an equation which represents the area of Felicia covered y in terms of the number of tiles she used.
Let x= Number of tiles
y=Area covered by Felicia's tile
The ratio of x and y remains constant.Therefore, it is direct proportion .
Equation of direction proportion is given by
Where
k=The value of ratio of x and y
x and y are variables
We have k=9
Substitute the values in the equation
Then, we get
This is required equation which representing the area of Felicia covered y in terms of the number of tile she used x.
Answer: 21 kilometers
Step-by-step explanation:
Because 13 plus 8 is equal to 21.
The correct answer is:
B. 
The radius of sphere A is multiplied by to produce the radius of sphere B.
This can't work because if there are 60 cars that means there are 240 car wheels and then 25 bikes means 50 bike wheels for a total of 290 wheels, if there was 1 more car then it would be 86 cars and motorcycles with 294 wheels or 2 more bikes would mean 87 cars and motorcycles with 294 wheels
Answer:
The answer is approximately 5.09 seconds.
Step-by-step explanation:
The given equation is:
f(x) = -5x^2 + 250
To find the elapsed time, x, set the equation equal to 120 and solve for x:
-5x^2 + 250 = 120
-5x^2 = -130
x^2 = -130/-5 = 26
x = Sqrt(26) = 5.09 seconds.
