Hi, here is the solution...

Part B)

The Navy Pier Ferris has the circumference is 56% of the circumference of the first Ferris wheel.

The Navy Pier Ferris Circumference = 439.6 feet

Let's assume "x" be circumference of first Ferris wheel.

56% of x = 439.6

0.56 x = 439. 6 [56% = 0.56]

x = 439.6/0.56

x = 785.

Therefore, the circumference of the first Ferris wheel is 785.

It is diameter = 785/3.14 = 250 feet

So it is radius = 250/2 = 125 feet.

Part C)

The circumference = 785 feet

Speed = Distance/Time

Speed = 785/9

Speed = 87.2 feet per minute.

That's it. Hope you will understand the steps.

Thank you. :)

Determine whether the graph of the quadratic function y = –3x2 + 2x + 5 opens upward or downward. Explain.

givi [52]

Answer:

The graph of the function opens downwards.

Step-by-step explanation:

The graph opens upward if the coefficient of x^2 is higher than 0.

But, the coefficient of x^2 (-3) is less than 0.

So the graph of the function opens downwards.

Priscilla received 240 votes in the election for student council president. That was 60% of the students who voted in the electi

stira [4]

Answer:

400 students voted in the election

Step-by-step explanation:

Given:

Total number of votes received by Priscilla = 240

This was 60% of the students who voted in the election.

To find: Total number of students who voted in the election

Solution:

Total number of votes received by Priscilla = 60% of Total number of students who voted in the election

240 = 60% of Total number of students who voted in the election

240 = $\frac{60}{100}$ × Total number of students who voted in the election

So,

Total number of students who voted in the election $=\frac{240(100)}{60}=400$

Answer: OPTION B.

Step-by-step explanation:

Given the following System of equations:

$\left \{ {{3x-5y=19} \atop {x+y=1}} \right.$

You can use the Elimination Method to solve it. The steps are:

1. You can mutliply the second equation by -3.

2. Then you must add the equations.

3. Solve for the variable "y".

Then:

$\left \{ {{3x-5y=19} \atop {-3x-3y=-3}} \right.\\.....................\\-8y=16\\\\y=\frac{16}{-8}\\\\y=-2$

4. Now that you know the value of the variable "y", you must substitute it into any original equation.

5. The final step is to solve for "x" in order to find its value.

Then:

$x+(-2)=1\\\\x=1+2\\\\x=3$

Therefore, the solution is:

$(3,-2)$
