What is the negative reciprocal of 3/4 or three over 4
Final answer:
The negative reciprocal of 3/4 is -4/3. This is found by inverting the fraction to get 4/3 and then applying the negative sign.
Explanation:
The negative reciprocal of a number refers to the value that, when multiplied by the original number, results in -1. For the fraction 3/4 (three over four), taking the reciprocal involves flipping the numerator and the denominator, which gives us 4/3. Making this reciprocal negative results in -4/3. The concept of reciprocals relates to the broader mathematical principles of multiplication and division, where negative exponents indicate the inverse of the corresponding positive exponent. For example, x to the power of -1 is equal to 1 divided by x to the power of 1, which demonstrates how negative exponents introduce division into the operation.

If ON = 5x – 4, LM = 4x + 7, NM = x – 7 and OL = 2y – 6, find the values of x and y for which LMNO must be a parallelogram. The diagram is not to scale. ...?
Opposite sides of parallelogram LMNO must be equal. By setting the equations for opposite sides equal and solving, we find x = 11 and y = 5.
Explanation:To determine the values of x and y for which LMNO is a parallelogram, we can use the properties of a parallelogram which state that opposite sides are equal in length. Since ON and LM are opposite sides, as well as OL and MN, we set their equations equal to each other:
ON = LM means 5x - 4 = 4x + 7.OL = NM means 2y - 6 = x - 7.Solving the first equation gives us x = 11. Substituting x = 11 in the second equation gives 2y - 6 = 4, which simplifies to y = 5. Therefore, the values are x = 11 and y = 5 for LMNO to be a parallelogram.
calculated a = 8³³ ÷ [4³² × 2³⁴ (2⁵ × 2²⁰)⁵ ÷ (16 × 2²³) (7⁵ ÷ 7⁵- 1)³² × 4]b = [(11 - 0¹¹) × (3³-3²) 1²⁰²⁰] × (3²-2³) - 3² × 2.
In a group of 10 batteries, 3 are dead. You choose 2 batteries at random.
Create a probability model for the number of good batteries.
The probability model for the number of good batteries when selecting 2 out of 10 with 3 dead is calculated as combinations of selecting good and dead batteries for each scenario. The probabilities are always divided by the total ways of drawing 2 from 10.
Explanation:This question is a typical problem related to probability. Firstly, we need to identify the number of ways we can draw 2 batteries randomly from this given set. We know there are 10 batteries in total with 3 dead ones. That leaves us with 7 good batteries.
Assuming 'X' is the number of good batteries we could select when drawing two batteries at random, 'X' could be 0, 1, or 2. Here are the three possible cases:
Both batteries are good (X = 2): The number of ways to select 2 batteries from 7 is combination of 7 by 2, denoted as C(7, 2). One battery is good and one is not (X = 1): The number of ways for this case can be calculated as the combination of picking 1 good battery from 7 and 1 dead battery from 3, denoted as C(7, 1)*C(3, 1). None of the batteries are good (X = 0): The number of ways for this case can be calculated as the combination of picking 2 dead batteries from 3, denoted as C(3, 2).To find out the probability of each scenario, we would have to divide by the total number of ways of drawing 2 batteries from 10, which equals to C(10, 2).

The solution to the system,___?___
, means that the plants will both be ___?___ centimeters tall after__?___weeks.
The solution of the system is h =7 and t = 6 means that the plants will both be 7 centimeters tall after 6 weeks.
Given that
A 4 cm bean plant grows at a rate of 1/2cm per week.
A 5.5 cm flower grows at a rate of 1/4cm per week.
If h is the height of the plant in centimeters and t is the number of weeks, then the system of equations is:

The ballpark made a total of $15,000 from ticket sales at Wednesday's game. The ballpark charges $20 for each adult ticket and $10 for each child's ticket. They sold 3 times as many children's tickets as adult tickets. Write a system of equations that can be used to determine the number of adult and child tickets sold.
To determine the number of adult and child tickets sold, we can set up a system of equations based on the given information. By solving the system of equations, we find that the number of adult tickets sold is 300, and the number of children's tickets sold is 900.
Explanation:Let's assume that the number of adult tickets sold is represented by 'x'.
Since the number of children's tickets sold is three times the number of adult tickets, the number of children's tickets sold can be represented as '3x'.
The total revenue from ticket sales is $15,000, so we can create the following equation:
20x + 10(3x) = 15,000
Simplifying this equation, we get:
20x + 30x = 15,000
Combining like terms, we have:
50x = 15,000
Dividing both sides by 50, we find:
x = 300
So, the number of adult tickets sold is 300, and the number of children's tickets sold is 3 times that, which is 900.

How much less would a 25 year old male pay for a $50,000 policy of 20 y life insurance @ $5.84 per $1000, than a straight life policy @ $15.66 per $1000?
A 25-year-old male would pay $491 less for a $50,000 policy of 20-year life insurance at $5.84 per $1,000, than for a straight life policy at $15.66 per $1,000. This is calculated by first determining the total cost of each policy and then finding the difference between the two.
Explanation:To calculate the cost difference between the 20-year life policy and the straight life policy, we first need to calculate the cost of each policy. The cost of the policies is given per $1,000, and the policies provided are worth a total of $50,000.
The 20-year life policy costs $5.84 per $1,000. Therefore, we calculate 50 (as $50,000 divided by $1,000 gives 50) multiplied by $5.84, which equals to $292. The straight life policy costs $15.66 per $1,000. Therefore, we calculate 50 multiplied by $15.66, which equals to $783.
To find out how much less a 25-year-old male would pay for the 20-year policy than the straight life policy, we subtract the cost of the 20-year policy from the cost of the straight life policy: $783 - $292 = $491.
So, a 25-year-old male would pay $491 less for a $50,000 20-year policy than a straight life policy.
