The Philips family had 3 cats. They needed to split 20 ounces of cat food among the three cats. How much cat food would each cat get? between what two whole numbers does your answer lie?
Each cat would get approximately 6.67 ounces of cat food, which falls between 6 and 7 ounces. The calculation is done by dividing the total amount of food (20 ounces) by the number of cats (3).
Explanation:The Philips family had to split 20 ounces of cat food among their 3 cats. To find out how much food each cat gets, we need to divide the total amount of food by the number of cats. Calculating this, 20 ounces ÷ 3 cats equals approximately 6.67 ounces per cat. Even though this is a decimal, if we consider whole numbers, the amount each cat gets falls between 6 and 7 ounces, since 6.67 is more than 6 and less than 7.
When dealing with fractions and division, it's essential to understand the concept of division and be able to find averages. The task at hand may often find itself related to dividing a quantity evenly among a number of recipients, much like in scenarios where we have to split a pie or determine individual portions.
To divide 20 ounces of cat food equally among three cats, each cat gets approximately 6.67 ounces. The amount of food per cat lies between the whole numbers 6 and 7.
Explanation:The question is asking how to divide 20 ounces of cat food equally among three cats. To find out how much each cat would get, you divide the total amount of cat food by the number of cats:
Determine the total amount of food: 20 ounces.Count the number of cats: 3 cats.Divide the total amount of food by the number of cats: 20 ounces ÷ 3 cats = approximately 6.67 ounces per cat.This calculation shows that each cat would get approximately 6.67 ounces of food. This value lies between the whole numbers 6 and 7. Therefore, when the Philips family divides the cat food, each cat gets a little more than 6 ounces but less than 7 ounces of food.
What is the solution set to the inequality-3x 5.92-15.4 for x in the set (-10,-5, 0, 5, 10)?
Final answer:
The solution set to the given inequality '-3x < 5.92 - 15.4' is {5, 10}.
Explanation:
The student's question seems to be about solving an inequality to find which values from a given set satisfy it. While the inequality itself appears to be incorrectly written or has a typo, I'll assume it's meant to be '-3x < 5.92 - 15.4'.
We can begin by simplifying the right side of the inequality:
5.92 - 15.4 = -9.48
So the inequality becomes:
-3x < -9.48
To solve for x, we divide both sides by -3, remembering to reverse the inequality sign because we are dividing by a negative number:
x > 9.48 / 3
x > 3.16
Now we can compare this result to the set of numbers given: (-10, -5, 0, 5, 10).
The only numbers greater than 3.16 are 5 and 10.
Therefore, the solution set to the inequality is {5, 10}.

You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as a fraction or percent. If necessary round your answer to the nearest hundredth.
The probability of spinning an odd number, flipping heads, then spinning a yellow is ????
probability = number of favourable outcomes / total number of outcomes
probability of spinning any number = 1/3
probability of tossing a coin = 1/2
probability of compound event = 1/3 * 1/2 * 1/3 = 1/18
probability of spinning an odd number, flipping heads, then spinning a yellow is = 2/3*1/2*1/3 = 1/9

The system of equations 4x-y=4(x+1) , y = 6 has:
A. one solution
B. infinitely many solutions
C. no solution
The system of equations 4x-y=4(x+1) and y=6 has no solution.
To determine the solution(s) of the system of equations, let's analyze each equation:
Equation 1: 4x - y = 4(x + 1)
Equation 2: y = 6
To simplify Equation 1, we can distribute 4 on the right side:
4x - y = 4x + 4
By rearranging terms, we have:
- y = 4
Comparing Equation 2 with this result, we see that the two equations are contradictory. Equation 2 states that y = 6, while the modified Equation 1 states that y = -4. This means there is no value of y that can simultaneously satisfy both equations.
Thus, the system of equations has no solution.
Therefore, the correct answer is C. no solution.

7b divided by 12=4.2 what is b
To solve for b in the equation 7b divided by 12 equals 4.2, multiply both sides by 12 and then divide by 7, resulting in b being equal to 7.2.
Explanation:To solve the equation 7b ÷ 12 = 4.2 for b, we must isolate b on one side of the equation. We can begin by multiplying both sides of the equation by 12 to cancel out the division by 12 on the left side. This results in the equation 7b = 4.2 × 12. To find the value of b, we then divide both sides of the equation by 7:
Multiply both sides by 12: 7b ÷ 12 × 12 = 4.2 × 12Simplify: 7b = 50.4Divide both sides by 7: 7b ÷ 7 = 50.4 ÷ 7b = 7.2Therefore, the value of b is 7.2.
To find the value of b in the equation 7b/12 = 4.2, multiply both sides by 12 and then divide by 7 to get b = 7.2. The value of b is 7.2.
Explanation:The student is asking how to find the value of b in the equation 7b divided by 12 equals 4.2. To solve for b, you can follow these steps:
Write down the original equation: 7b / 12 = 4.2.Multiply both sides of the equation by 12 to eliminate the denominator: 12 * (7b / 12) = 12 * 4.2, which simplifies to 7b = 50.4.Divide both sides by 7 to solve for b: 7b / 7 = 50.4 / 7, which gives b = 7.2.Therefore, the value of b is 7.2.

Find the face value of a simple discount note that will provide the $24,700 in proceeds if he plans to repay the note in 180 days and the bank charges an 8% discount rate.
Round to the nearest cent.
To find out the face value of a simple discount note that will provide a proceed of $24,700 with an 8% discount rate for 180 days, use the formula FV = P / (1 - (r * t)). Plug in the given values and compute the answer. The result is the required face value and should be rounded to the nearest cent.
Explanation:To find out the face value of a simple discount note, we can use the formula FV = P / (1 - (r * t)) where FV represents the face value, P is the proceeds, r is the discount rate, and t is the time in years.
In the problem, P = $24,700, r = 8% or 0.08 (expressed as a decimal), and t = 180/365 because there are 365 days in a year and the note is for 180 days. Let's substitute these values into the formula:
FV = 24700 / (1 - (0.08 * (180/365))
When you calculate the expression on the right, the answer will be the face value required to get a proceed of $24,700 with an 8% discount rate for 180 days. Round to the nearest cent for your final answer.

Find the fuction h (x) =f(x) - g (x) if f (x)=3^x and g (x)= 3^2x - 3^x
To find h(x) = f(x) - g(x), we substitute and simplify the given functions. The result is h(x) = 2 × 3ˣ - 3²ˣ. This solution involves basic algebraic manipulation and exponent rules.
Let's start by defining the given functions:
f(x) = 3ˣg(x) = 3²ˣ - 3ˣWe need to find h(x) = f(x) - g(x). Substitute the expressions for f(x) and g(x):
h(x) = 3ˣ - (3²ˣ - 3ˣ)Now simplify the expression inside the parentheses:
h(x) = 3ˣ - 3²ˣ + 3ˣCombine like terms:
h(x) = 3ˣ+ 3ˣ - 3²ˣh(x) = 2 × 3ˣ - 3²ˣThus, the function h(x) = 2 × 3ˣ - 3²ˣ is found by subtracting g(x) from f(x).
Use Cavalieri’s Principle to calculate the exact volume of an oblique cylinder with a height of 10 meters and a circular base with a radius of 8 meters
Answer: Volume of an oblique cylinder is 2011.43 sq.m.
Step-by-step explanation:
Since we have given that
Radius of a cylinder = 8 meters
Height of a cylinder = 10 meters
Cavelieri's Principle states that volume of an oblique cylinder is same as the volume of right circular cylinder with equal radius and height.
As we know the formula for "Volume of cylinder":
[tex]Volume=\pi r^2h\\\\V=\frac{22}{7}\times 8\times 8\times10\\\\V=\frac{14080}{7}\\\\V=2011.43[/tex]
Hence, Volume of an oblique cylinder is 2011.43 sq.m.
You have a $50 gift card to the same site. You want to buy an album with 16 tracks for $12.99 and then use the rest of the gift card for single tracks. How many songs can you buy with the gift card?
Final answer:
After purchasing an album for $12.99 from the $50 gift card, the remaining balance is $37.01, which allows the purchase of 37 more single tracks, assuming each track costs $1.
Explanation:
To determine how many songs can be bought with a $50 gift card after purchasing an album for $12.99, we need to subtract the cost of the album from the total amount on the gift card. So, we have:
Total amount on gift card: $50Cost of album: $12.99Subtracting the cost of the album from the gift card amount gives us:
$50 - $12.99 = $37.01
Assuming that each single track costs $1 as per the scenario provided, we can divide the remaining balance by the cost per single track:
$37.01 ÷ $1 per track = 37 tracks
This means that you can purchase 37 more single tracks with the remaining balance on the gift card.
