Answer:
401.92
Step-by-step explanation:
3.14 x (4x4) x 8 = 401.92
Answer:
Student's tickets: 60
Adult's tickets: 190
I think this is right
Step-by-step explanation:
"Let x represent the number of tickets sold to students under the age of 16. Let y represent those over the age of 16.
Equation 1, number of tickets sold:
The total number of tickets sold to students under the age of 16 plus the number of tickets sold to students over 16 must equal 250 (since the theater was sold out). The equation becomes:
x + y = 250
Equation 2, revenue from tickets sold.
The total revenue was $910. The cost of tickets under 16 is $2.50 and the cost of tickets over 16 is $4.00. The equation becomes:
2.50 * x + 4.00 * y = 910.00
The system of equations to solve is:
x + y = 250
2.50 * x + 4.00 * y = 910.00 "
I think it is the third one necause......
Answer: m less-than-or-equal-to 17
Step-by-step explanation: First lets write an equation to solve for m, the amount of miles Henry can afford in the taxi.
The inequality 0.75m - 1.25 less than or equal to 14 represents this.
Solve for m.
0.75m - 1.25 + 1.25 = 14 - 1.25
0.75m = 12.75
We need to make m be equal to one mile not 0.75, so divide both sides by 0.75.
0.75m/0.75 = 12.75/0.75
m = 17
So m is less than or equal to 17
The exponential model indicates that hydropower energy generation has increased by 2.3% (0.023).
<h3>What is an exponential function?</h3>
An exponential function can be defined as a type of mathematical equation whose numerals are generated by a constant that's raised to the power of an argument.
Based on an exponential model for this data, we can deduce the following:
- Mathematically, the exponential function for the given data is given by
- The exponential model indicates that hydropower energy generation has increased by 2.3% (0.023).
- Hydropower energy generation in 25 years after 1970 was closest to 2270 TWh.
- Because the correlation coefficient indicates a strong correlation between the model and the data, this prediction can be accepted with confidence interval of 98.7%.
