Ari has been paying attention to the number of calories she burns while exercising. One day she spent 3 hours hiking, and 4 canoeing, and she calculated that she burned 2338 calories. The next day, she hiked for 7 hours and canoed for one hour, and she calculated that she burned 3322 calories. How many calories per hour does Ari burn doing each exercise?
By setting up a system of equations, we find that Ari burns 438 calories per hour hiking and 256 calories per hour canoeing.
To determine the number of calories Ari burns per hour doing each exercise, we need to set up a system of equations based on the given information. Let x represent the number of calories burned per hour hiking, and y represent the number of calories burned per hour canoeing.
We are given two situations:
3 hours of hiking and 4 hours of canoeing burn 2338 calories: 3x + 4y = 2338.
7 hours of hiking and 1 hour of canoeing burn 3322 calories: 7x + y = 3322.
We have the following system of equations:
3x + 4y = 2338
7x + y = 3322
To solve the system, we can first multiply the second equation by 4 to eliminate y:
4(7x + y) = 4(3322)
28x + 4y = 13288
Now, subtract the first equation from this result:
(28x + 4y) - (3x + 4y) = 13288 - 2338
25x = 10950
x = 10950 / 25
x = 438
Ari burns 438 calories per hour hiking.
To find y, substitute x = 438 into the first equation:
3(438) + 4y = 2338
1314 + 4y = 2338
4y = 2338 - 1314
4y = 1024
y = 256
Ari burns 256 calories per hour canoeing.
Thus, the results reveal that Ari burns 438 calories per hour hiking and 256 calories per hour canoeing.

Convert 9 cubic centimeters to fluid ounces (to the nearest thousandth).
Answer:
0.304 oz.
Step-by-step explanation:
We are asked to convert 9 cubic centimeters to fluid ounces (to the nearest thousandth).
We know that 1 cubic centimeter equals 0.033814 fluid ounces. To convert 9 cubic centimeters to fluid ounces, we will multiply 9 by 0.033814.
[tex]\text{9 cm}^3=\text{9 cm}^3\times \frac{\text{0.033814 oz}}{\text{cm}^3}[/tex]
[tex]\text{9 cm}^3=9\times \text{0.033814 oz}[/tex]
[tex]\text{9 cm}^3=0.304326\text{ oz}[/tex]
[tex]\text{9 cm}^3\approx 0.304\text{ oz}[/tex]
Therefore, 9 cubic centimeters equals 0.304 fluid ounces to the nearest thousandth.

The front of a storage bunker can be modeled by y=-5/216(x-72)(x+72), where x and y are measured in inches. The x axis represents the ground. Find the width of the bunker at ground level.
The width of the bunker at ground level is 14.58 inches.
Explanation:The x-axis is the ground level, so the y-axis must be the scale for the length. Using the provided model, the x-intercepts, namely where the x-axis gets touched, we can just get the distance between them and that's the ground-level width.
The width of the bunker at ground level can be found by substituting x = 0 into the equation y = -5/216(x-72)(x+72).
This equation represents a quadratic function, which means it is a parabola.
By substituting x = 0, we get y = -5/216(-72)(72)
= 14.58 inches.

Given the volume of Wesley's cube = 8 cubic centimeters.
We know the formula for volume of cube is given as follows :-
Volume of cube = (side) x (side) x (side)
8 = (side)³
side = [tex]\sqrt[3]{8} =\sqrt[3]{2*2*2} =2[/tex]
Hence, Wesley's cube dimensions are 2 centimeters.
The square must have side length as 2 centimeters.
If smallest square G represents 1 centimeters, then clearly it is H = 2 centimeters.
So, square H is the final answer.
A hotel is in the shape of a square pyramid. Each side of the base is 183 meters long and the height is 110 meters. What is the hotel's volume? Enter your answer in the box
Answer:
1,227,930 m²
Step-by-step explanation:
We are given that,
Base of the pyramid = 183 meter
Height = 110 meter.
Since, we know,
Volume of a square pyramid = [tex]Base^2\times \frac{Height}{3}[/tex]
We have,
Volume of the square pyramid = [tex]183^2\times \frac{110}{3}[/tex]
i.e. Volume of the square pyramid = [tex]33489\times 36.667[/tex]
i.e. Volume of the square pyramid = 1,227,930 m²
Hence, the volume of the square pyramid is 1,227,930 m².
It is very common for television series to draw a large audience for special events of for cliff-hanging story lines. suppose that on one of these occasions, the special show drew viewers from 38.2% of all us tv households. suppose that three tv households are randomly selected. what is the probability that all three households viewed this special show?
To find the probability that all three randomly selected households watched a special TV show when 38.2% of all households watched it, you multiply the probability for one household by itself three times, resulting in approximately 0.055 or 5.5%.
The question asks about calculating the probability that all three randomly selected US TV households watched a special television show, given that 38.2% of all US TV households viewed it. To find this probability, we use the rule of independent events since the viewing status of one household is assumed to not affect another. The probability that all three households viewed this show can be calculated by multiplying the probability of one household viewing the show three times.
The calculation would look like this:
0.382 (the probability one household watched the show) x 0.382 x 0.382 = 0.055 (approximately).
This is the probability that all three households viewed the special show.

Item 9 A company that offers tubing trips down a river rents tubes for a person to use and “cooler” tubes to carry food and water. A group spends $270 to rent a total of 15 tubes. Write a system of linear equations that represents this situation. Use xx to represent the number of one-person tubes rented and yy to represent the number of cooler tubes rented. How many of each type of tube does the group rent?
The group rents 11 one-person tubes and 4 cooler tubes and the two system of equations are:
x + y = 15
20x + 12.5y = 270
And the solution: x = 11, y = 4.
Define Variables:
x = number of one-person tubes rented
y = number of cooler tubes rented
Translate information into equations:
Total tubes: The group rents a total of 15 tubes. Translate this into an equation:
x + y = 15
Cost: Each one-person tube costs $20 and each cooler tube costs $12.50. Use these known costs to represent the total cost:
20x + 12.5y = 270
System of Equations:
x + y = 15
20x + 12.5y = 270
Solving for x and y:
Elimination
Multiply the first equation by -12.5:
-12.5x - 12.5y = -187.5
Add the top and bottom equations:
7.5x = 82.5
Divide both sides by 7.5:
x = 11
Substitute the value of x back into the first equation to solve for y:
11 + y = 15
y = 4
The group rents 11 one-person tubes and 4 cooler tubes.
Therefore, the two system of equations are:
x + y = 15
20x + 12.5y = 270
And the solution: x = 11, y = 4.

A company that offers tubing trips down a river rents tubes for a person to use and “cooler” tubes to carry food and water. A group spends $270 to rent a total of 15 tubes. Write a system of linear equations that represents this situation. Use x to represent the number of one-person tubes rented and y to represent the number of cooler tubes rented. a one person tube costs $20 and a cooler tube costs $12.50 How many of each type of tube does the group rent? what are the two system of equations?
The system of equations representing the situation is x + y = 15 and 20x + 12.50y = 270. The group rents 11 one-person tubes and 4 cooler tubes.
Let's denote:
x as the number of one-person tubes rented
y as the number of cooler tubes rented
Given:
The cost of renting one-person tube is $20
The cost of renting a cooler tube is $12.50
The total amount spent by the group is $270
We can set up the following system of linear equations to represent the situation:
The total number of tubes rented:
x (number of one-person tubes) + y (number of cooler tubes) = 15 (total tubes)
The total cost spent:
20x (cost of one-person tube) + 12.50y (cost of cooler tube) = 270
So, the system of equations is:
x + y = 15
20x + 12.50y = 270
To find the number of each type of tube rented, we can solve this system of equations.
Now, let's solve this system of equations:
From equation 1, we can express x in terms of y:
x = 15 - y
Substitute this expression for x into equation 2:
20(15 - y) + 12.50y = 270
Now, solve for y:
300 - 20y + 12.50y = 270
-7.50y = -30
y = 4
Now that we have found y, let's substitute it back into equation 1 to find x:
x = 15 - 4
x = 11
So, the group rents 11 one-person tubes and 4 cooler tubes.
