Jane is choosing between two exercise routines. In Routine # 1, she burns 22 calories walking. She then runs at a rate that burns 5.75 calories per minute. In Routine #2, she does only running, burning 8.5 calories per minute. For what amounts of time spent running will Routine #1 burn at least as many calories as Routine #2? Use t for the number of minutes spent running, and solve your inequality for t.
Answer: 3.8 minutes!
Step-by-step explanation:
The answer is 3.8 minutes. To solve for t, we need to set up an inequality where the calories burned in routine #1 is equal to or greater than the calories burned in routine #2. We can write this as 22 + 5.75t ≥ 8.5t. Then, we can subtract 8.5t from both sides to get 22 ≥ -2.75t. Finally, we can divide both sides by -2.75 to get t ≤ -8/2.75, which simplifies to t ≤ 3.8. Therefore, Jane needs to run for 3.8 minutes in Routine #1 in order to burn at least as many calories as Routine #2.
Answer:
Jane needs to run for 8 minutes or less in Routine #1 for it to burn at least as many calories as Routine #2. If she runs for more than 8 minutes in Routine #1, then Routine #2 will burn more calories.
Step-by-step explanation:
In Routine #1, the total number of calories burned is:
C1(t) = 22 + 5.75t
The first term represents the calories burned while walking, and the second term represents the calories burned while running.
In Routine #2, the total number of calories burned is:
C2(t) = 8.5t
This represents the calories burned while running, as there is no walking in Routine #2.
We want to find the values of t for which C1(t) is greater than or equal to C2(t). So we can set up the following inequality:
C1(t) ≥ C2(t)
Substituting the expressions for C1(t) and C2(t), we get:
22 + 5.75t ≥ 8.5t
Simplifying the inequality, we get:
22 ≥ 2.75t
Dividing both sides by 2.75, we get:
t ≤ 8
So Jane needs to run for 8 minutes or less in Routine #1 for it to burn at least as many calories as Routine #2. If she runs for more than 8 minutes in Routine #1, then Routine #2 will burn more calories.

A medium-sized orange contains 68 calories. Which is one-fifth the number of calories in a slice of cheese pizza.
If one slice of cheese pizza contains 340 calories, and a medium-size orange has one-fifth that number of calories, we can find the number of calories in a medium-size orange by dividing 340 by 5. Calories in a medium-sized orange = [tex]\frac{340}{5}[/tex] calories = 68 calories. The division is an arithmetic operation used to find out how many times one number is contained within another number. The result of a division operation is called the quotient.

A rigid motion maps each part of a figure to an______ part of its image
A rigid motion maps each part of a figure to an Rotation.
What is rotation ?
In physics, rotation refers to the movement of an object around an axis or a fixed point. When an object rotates, every point on the object moves in a circle around the axis of rotation, and the object typically completes one full rotation or revolution after it has moved a full 360 degrees around the axis.
The study of rotation in physics is important in many fields, including mechanics, electromagnetism, and quantum mechanics. Rotational motion is characterized by several key parameters, including the angle of rotation, the angular velocity (how fast the object is rotating), and the angular acceleration (how quickly the angular velocity is changing).
In addition, rotational motion is subject to a number of physical laws and principles, such as Newton's laws of motion, which describe the relationship between the forces acting on a rotating object and its resulting motion. Other principles, such as the conservation of angular momentum, relate to the conservation of the rotational energy of a system as it undergoes rotational motion.
Therefore, a rigid motion maps each part of a figure to an Rotation.

Three spheres each with charge Q uniformly distributed through its volume Rank the spheres according to the magnitude of the electric field they produced at point P (greatest firstl P (1) (2) (3) Select one: a. 3 > 2 > 1 b. all tie c. 1>2>3 d. 1 and 2 tie > 3 e. 2 > 3 >1
The correct ranking of the spheres according to the magnitude of the electric field they produce at point P (greatest first) is: 1 > 2 > 3. The answer is option C.
Since all three spheres have the same charge Q and radius, the magnitude of the electric field at point P due to each sphere is proportional to 1/d^2, where d is the distance between the center of the sphere and point P. Therefore, the sphere closest to point P will produce the greatest electric field at that point.
Assuming that the three spheres are arranged in a straight line with sphere 1 being the closest to point P and sphere 3 being the farthest, we can rank the spheres according to the magnitude of the electric field they produce at point P as follows:
Sphere 1 produces the greatest electric field at point P since it is the closest to it.
Sphere 2 produces the second greatest electric field at point P since it is farther away from point P than sphere 1 but closer than sphere 3.
Sphere 3 produces the smallest electric field at point P since it is the farthest from it.

what is 3/5 into a percent?
3/5 = 0,6, it is 0.6 × 100 = 60%
Therefore, 3/5 is expressed as 60% in terms of percentage.
Percentage:
In mathematics, a percentage is a number or ratio that represents a fraction of 100. This is one way of representing a dimensionless ratio between two numbers. Other methods include ratios, fractions, and decimals. Percentage is often indicated by writing a "%" sign after the number.
According to the Question:
To convert a fraction to a decimal, it's always best to look at the denominator first. If the denominator only has prime factors of 2 and 5, you can easily pick a number multiplied by the denominator and convert it to a denominator that is a power of 10, and the result is the final prime number. If you have prime factors other than 2 and 5, converting to decimal takes longer and can result in infinite but repeating decimals.
In this case, the denominator is 5, so you can easily convert to decimal by multiplying the denominator and numerator by 2.
(3 × 20) / (5 × 20) = 60/100
Now,
To convert a fraction to a percentage, simply multiply by 100 and put a % sign next to the result.
As 3/5 = 0,6, it is 0.6 × 100 = 60%

The angle of depression from the top of the lighthouse to the boat is 0 degrees.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Using trigonometry, we can find the horizontal distance x:
tan(15) = x / 228
x = 228 tan(15)
x = 57.87 feet
Therefore, the horizontal distance between Ryan and the dolphin is 57.87 feet.
2. Using trigonometry, we can find the horizontal distance between the airplane and the control tower:
tan(56) = x / 7450
x = 7450tan(56)
x = 10735.96 feet
Therefore, the airplane is approximately 10735.96 feet away from the control tower
3. We want to find the angle of depression from the top of the lighthouse to the boat. Since the lighthouse is 275 feet above the water, we can use trigonometry to find the height of the lighthouse above the boat:
tan(90) = 275 / x
x = 275 / tan(90)
x = undefined

What is 4 2 1 rule ?
The 4-2-1 rule is a guideline used to help determine the amount of water an individual needs to drink each day.
The rule states that an individual should drink 4 liters of water for every 50 pounds of body weight, 2 liters of water for every 50 pounds of body weight if they are exercising, and 1 liter of water for every 50 pounds of body weight if they are in a hot or dry environment.
To calculate how much water you need to drink using the 4-2-1 rule, simply follow these steps:
1. Determine your body weight in pounds.
2. Divide your body weight by 50 to get the number of 50-pound increments in your weight.
3. Multiply the number of 50-pound increments by 4 to get the amount of water you need to drink if you are not exercising or in a hot or dry environment.
4. Multiply the number of 50-pound increments by 2 to get the amount of water you need to drink if you are exercising.
5. Multiply the number of 50-pound increments by 1 to get the amount of water you need to drink if you are in a hot or dry environment.
6. Add the amounts from steps 3, 4, and 5 together to get the total amount of water you need to drink each day.
For example, if you weigh 150 pounds, you would need to drink 4 liters of water for every 50 pounds of body weight (150 / 50 = 3), 2 liters of water for every 50 pounds of body weight if you are exercising (3 x 2 = 6), and 1 liter of water for every 50 pounds of body weight if you are in a hot or dry environment (3 x 1 = 3). Therefore, you would need to drink a total of 13 liters of water each day (4 + 6 + 3 = 13).
