Answer:
c. 1 1/9 cups
Step-by-step explanation:
To find cups per pound, divide cups by pounds.
(5/6 cup)/(3/4 pound) = (5/6)/(3/4) cup/pound
= (5/6)×(4/3) cup/pound . . . . . . . invert the denominator and multiply
= 20/18 cup/pound = 10/9 cup/pound = 1 1/9 cup/pound

On Wednesday, Miguel's bank account balance was -$55. On Thursday, his balance was less than that. Use absolute value to describe Miguel's balance on Thursday as a debt. In this situation, -$55 represents a debt of _________. On Thursday, Miguel had a debt of _____________than $55.
In this situation, the -$55 represents the debt of $55, since this happens when Miguel does not have enough money in his account to cover payments or transactions. On Thursday, he has a debt of more than $55. The explanation behind this is if an account balance is less than -55 dollars, it exemplifies a debt bigger than 55 dollars.

Which equation could you use to solve for x in the proportion 4/5=9/x ?
Answer:
4x = 45 Chi3 is completely wrong
Step-by-step explanation:
To solve for x in the proportion StartFraction 4 over 5 EndFraction = StartFraction 9 over x EndFraction, you can use the cross multiplication method.
First, multiply the numerator of the left fraction (4) by the denominator of the right fraction (x). Then, multiply the denominator of the left fraction (5) by the numerator of the right fraction (9).
This gives you the equation: 4x = 5 * 9.
Simplifying the equation, you get: 4x = 45.
To isolate x, divide both sides of the equation by 4: x = 45/4.
So, the correct equation to solve for x in the given proportion is 4x = 45.

A Ferris wheel with a radius of 13 m is rotating at a rate of one revolution every 2 minutes. How fast is a rider rising when the rider is 18 m above ground level?
To find the speed at which the rider is rising, we use trigonometry and differentiation to calculate the rate of change of the height with respect to time. The speed is approximately -8.14 m/min.
Explanation:To find the speed at which the rider is rising, we need to find the rate of change of the height of the rider with respect to time. This can be done using the concept of trigonometry and differentiation.
Since the Ferris wheel completes one revolution every 2 minutes, the angular speed is given by 2π radians per 2 minutes, which simplifies to π radians per minute.
The height of the rider can be represented by a sinusoidal function, and by taking the derivative of this function, we can find the rate of change of the height with respect to time. In this case, the derivative would be -13sin(t), where t is the time in minutes.
Substituting t = 18 minutes into the derivative equation, we can calculate the rate at which the rider is rising. Plugging in the value, we get a speed of -13sin(18) m/min, which is approximately -8.14 m/min.

if (sin(()−1))p =2cos(()−1)q , show that p^2 =4q^2 (1− q^2) ?.
To show that p^2 = 4q^2(1-q^2), we use trigonometric identities and algebraic manipulations to prove the given equation sin((θ-1)p) = 2cos((θ-1)q). By taking the inverse sine, squaring both sides, and applying trigonometric identities, we arrive at the desired result.
Explanation:To show that p^2 = 4q^2(1-q^2), we need to start with the equation sin((θ-1)p) = 2cos((θ-1)q). We can use the trigonometric identities and algebraic manipulations to prove this equation.
Start by taking the inverse sine of both sides: (θ-1)p = sin^(-1)(2cos(θ-1)q).Next, use the identity sin^(-1)(x) = θ: (θ-1)p = sin^(-1)(2cos(θ-1)q) becomes p = sin^(-1)(2cos(θ-1)q)/(θ-1).Square both sides of the equation to eliminate the inverse sine: p^2 = (sin^(-1)(2cos(θ-1)q)/(θ-1))^2.Apply the identity sin^2(θ) = 1 - cos^2(θ) to the right side of the equation: p^2 = (1 - cos^2(sin^(-1)(2cos(θ-1)q)/(θ-1))))Finally, simplify the equation using algebraic manipulations to arrive at p^2 = 4q^2(1-q^2).Learn more about Trigonometry here:https://brainly.com/question/31896723

if 60 blimps each had 70 people on board,how many people would be riding on the blimp
By multiplying the number of blimps (60) with the number of people on each blimp (70), we find that a total of 4200 people would be riding on the blimps.
Explanation:This is a simple multiplication problem, where you simply need to multiply the number of blimps by the number of people on each blimp to get the total number of people. In this case, we have 60 blimps each carrying 70 people. So we multiply 60 blimps by 70 people to get the total number of people, which is 4200 people. Therefore, if 60 blimps each had 70 people on board, a total of 4200 people would be riding on the blimps.

The cost function for a particular product is given by C(x)=0.0001 x^3−0.015x^2+13.1x+120 dollars, where 0≤x≤60. Find the minimum marginal cost of the product, rounded to the nearest cent.
Final answer:
To find the minimum marginal cost, differentiate the cost function to get the MC function, find its critical points, and evaluate it at these points within the interval.
Explanation:
To find the minimum marginal cost of the product, we need to differentiate the cost function C(x) with respect to x to find the marginal cost function, then find the critical points within the given interval by setting the derivative to zero and solving for x.
The cost function is C(x) = 0.0001x^3 - 0.015x^2 + 13.1x + 120. The marginal cost (MC) function, MC(x), is the first derivative of the cost function with respect to x:
MC(x) = dC/dx = 0.0003x^2 - 0.03x + 13.1.
To find the minimum marginal cost, we need to differentiate the MC function to find its critical points:
dMC/dx = 0.0006x - 0.03
Setting dMC/dx equal to zero and solving for x gives us:
0.0006x - 0.03 = 0
x = 50
After finding the critical point, we check if it is within the interval [0,60] and evaluate the MC function at x = 50 to find the minimum MC. Rounding it to the nearest cent, we have:
MC(50) = 0.0003(50)^2 - 0.03(50) + 13.1
The final minimum marginal cost of the product is calculated and rounded to determine the minimum cost to produce one more unit of output.

A machine is set to fill the small-size packages of m&m candies with 56 candies per bag. a sample revealed: three bags of 56, two bags of 57, one bag of 55, and two bags of 58. to test the hypothesis that the mean candies per bag is 56, how many degrees of freedom are there?
In statistics, the amount of degrees of freedom is the quantity of values in the final computation of a statistic that are free to differ. In this case, you can get the answer by adding the number of bags and subtracting 1.
So in computation, this would look like: 3 + 2 + 1 + 2 - 1 = 7
Therefore, 7 is the degrees of freedom.
Final answer:
The number of degrees of freedom for the hypothesis test that the mean candies per bag is 56 is 7, calculated by subtracting one from the total number of sampled bags.
Explanation:
To calculate the number of degrees of freedom for the hypothesis test that the mean candies per bag is 56, we use the sample size minus one. The sample size is the number of observations, which is the total count of bags sampled. In this case, we have a total of 8 bags (three bags of 56, two bags of 57, one bag of 55, and two bags of 58). Therefore, the degrees of freedom for this test would be 8 - 1 = 7.
what is the indicated operation of
10 3/7 + 19 5/9
Final answer:
To find the sum of mixed numbers, convert them into improper fractions and then add the fractions together. The answer here is 1889/63.
Explanation:
The student’s question “what is the indicated operation of 10 3/7 + 19 5/9” asks to perform the operation of addition between two mixed numbers. The indicated operation is addition. To add these mixed numbers, you first add the whole numbers (10 + 19) and then add the fractions (3/7 + 5/9). When adding fractions, find a common denominator, in this case, 63, and convert the fractions to have this common denominator before adding.
To find the sum of mixed numbers, we first convert them into improper fractions.
10 3/7 becomes 73/7 and 19 5/9 becomes 176/9.
Then, we add the numerator of the fractions and keep the denominator the same. So, 73/7 + 176/9 = (73 * 9 + 7 * 176)/(7 * 9). Which gives 1889/63.

What is the sum of 1.53 + 2.786 + 3.3 written with the correct number of significant figures?
Answer:
1.53 + 2.786 + 3.3 = 7.6
Step-by-step explanation:
Significant figures is the number of digits that carry precision in a number.
In mathematical operations involving significant figures, an answer is no more precise that the least precise number used to get the answer.
For addition, look at the places to the decimal point. Add in the normal fashion, then round the answer to the least number of places to the decimal point of any number in the problem.
To find the sum of 1.53 + 2.786 + 3.3 you must:
[tex]1.53 + 2.786 + 3.3\\4.316 + 3.3\\7.616\\[/tex]
Because 3.3 is the number with the smallest sig figs, the result should have as many decimal places as the number with the smallest sig figs. Therefore, 7.6.
