It costs $8 to enter a fair and $3 for each ride. Which of the following equations represents the total cost, y?

1 answer:

4 0

So the 8 dollars to enter the fair is a flat rate that everyone has to pay no matter how many rides they ride. so this would just become +8. the 3 dollars per ride becomes dependent on how many rides you ride. so if you rode 3 it would be 3(3) + 8 . where as if you rode 4 it would be 3(4) + 8. so the equation becomes y = 3x +8, where y is the total amount of money you spend and x is the number of rides you ride.

What is the error in the equation

dimulka [17.4K]

Answer:

The fifth line contains the error.

Step-by-step explanation:

Line 1 is the equation.

Lines 2, 3, and 4 are correct.

The error is in the 5th line.

The square root of a negative number is not a real number, so if this problem is solved only with real numbers, there is no solution.

If imaginary numbers are allowed, then the last line should read:

$x = \pm\dfrac{i\sqrt{11}}{2}$

Two cylinders. The smaller cylinder has height labeled as 6 cm. The larger cylinder has height labeled as 18 cm.

Yakvenalex [24]

Answer: first option.

Step-by-step explanation:

You know that the height of the smaller cylinder is 6 cm and the height of the larger cylinder is 18 cm, then you can find the volume ratio. This is:

$Volume\ ratio=(\frac{6cm}{18cm})^3\\\\Volume\ ratio=\frac{1}{27}$

Knowing that the volume of the larger cylinder is 40,635 cubic centimeters, you need to multiply it by the volume ratio to find the volume of the smaller cylinder.

Therefore:

$V_{smaller}=\frac{1}{27}(40,635\ cm^3)\\\\V_{smaller}=1,505\ cm^3$
