big lake bob spends his time carving fishing lures and duck decoys. if big lake bob spends all of his time carving fishing lures he can carve 100 lures in a week. if he spends all of his time carving duck decoys he can carve 30 decoys in a week. for every 6 duck decoys big lake bob carves he must give up 20 fishing lures.
Yes, for every 6 duck decoys big lake bob carves he must give up 20 fishing lures.
Production possibility schedule:-
Fish lures:
Fish lures in one week = 100
lures in a day = 20
So, 100-20 = 80
80 - 20 = 60
60 - 20 = 40
40 - 20 = 20
20 - 20 = 0
Duck decoys:
Duck in one day = 0
So, 0 + 6 = 6
6 + 6 = 12
12 + 6 = 18
18 + 6 = 24
24 + 6 = 30
number of duck decoy in a week = 30
Hence, For every 6 duck decoys Bob carves 20 lures.

Creating a tonne of random numbers between 40 and 70 points so that we can see that the population range is equal to 70. That is presumably the oldest value that is still valid. The population range is the sum of the data generated at the highest level and the lowest level. The population range is now 30 points. by taking a handful of random samples.
We want a sample table containing random samples of the data so we don't have to worry about this. Going through the samples with the new table that will be generated here and want to find this range by taking the max of each sample. Subtracting the mean from each sample from the range samples from 1 to 10. The range for the initial data was 30 points because the entire range was 40 to 70 points; nevertheless, we can observe that this range varies from 64 to 70 points.
We made the table because we wanted the mean of the average of our separate ranges to be 21.7. The mean value of the ranges in 100 samples will be discovered if the sample size is increased.

Suzanne pays $21.03 in sales tax for the computer upgrades.
What is tax?Tax in math is a type of mathematical problem that involves the distribution of a certain amount of money among several parties. The problem is solved by calculating the amount of money each party needs to pay in order to make the distribution fair and equitable. This type of math problem is often used to determine the amount of taxes that need to be paid by individuals or businesses. Tax problems can also be used to analyze the effects of different tax policies on the economy.
This amount is rounded to the nearest cent and is calculated by multiplying the pre-tax cost of the upgrades ($311.60) by the sales tax rate (6.75%). Thus, the equation would be: $311.60 x 6.75% = $21.03.

How to evaluate the arithmetic series?
An arithmetic progression ( AP ) is a sequence of numbers such that the difference between the consecutive terms is constant.
From the given information, we can get the first term (a) and last term (l) of the sequence by substituting n = 1 and n = 45 respectively into the given expression, (4n + 9). That is:
a = 4(1) + 9 = 13
l = 4(45) + 9 = 189
Sum of all terms in a finite AP with the first term (a) and last term (l) is given by:
S = n/2(a + l)
S = 45/2 (13+189) = 4545

What is the angular velocity of the nail in radians per hour?
263,187.70 rad / hour is the angular velocity of the nail in radians per hour.
What is angular velocity?A pseudovector used in physics to express how quickly an object's angular position or orientation changes over time is called an angular velocity, rotational velocity, or angular frequency vector. angular velocity is the speed at which an object rotates or revolves around an axis or alters the angle between two bodies. This displacement is depicted in the illustration by the angle between a line on one body and a line on the other.The equation relating angular velocity and linear velocity is:
w = v / r
where,
w = angular velocity, v = linear velocity, and r = radius
Since r is in inches, convert v to inches:
v = (54 miles per hour) * (63360 inches / mile)
v = 3,421,440 inches / hour
Solving for w:
w = (3,421,440 inches / hour) / 13 inches

Based on whether the function is increasing or decreasing, the slope values are calculated. Then, the required slope values of A, B, C, D, E, and F are 1/2, 0, 1, 3, -3, and -1.
We match the slopes with the points in the given graph. For this, we must know that,
When the tangent to the curve is horizontal, the slope is zero.When the function is descending, the slope is negative.When the function is rising, the slope is positive.We may determine the rate at which the function is increasing or decreasing by measuring the slope's magnitude. Here, in this graph, first, the slope is zero at B. Therefore, the value of the slope in B is zero (0).
We can determine from the graph that the slope is descending at points E and F. Additionally, the slope is ascending at points A, C, and D.
Therefore, slope D> slope C> slope A> slope B. So, the slope values for D, C, and A are 3, 1, and 1/2 respectively.

One ticket cost $6, and two tickets for a couple cost $10. You sold 196 tickets and gained $1076. How many couples bought tickets?
Answer:
How many couples bought tickets?
50
Step-by-step explanation:
s + 2c = 196 Eq. 1
6s + 10c = 1076 Eq, 2
s = single tickets
c = couple tickets
From Eq. 1:
s = 196 - 2c Eq. 3
Replacing Eq. 3 in Eq. 2:
6(196-2c) + 10c = 1076
(6*196 + 6*-2c) + 10c = 1076
(1176 - 12c) + 10c = 1076
1176 - 2c = 1076
1176 - 1076 = 2c
100 = 2c
c = 100/2
c = 50
From Eq. 3:
s = 196 - 2c
s = 196 - 2*50
s = 196 - 100
s = 96
Check:
From Eq. 2:
6s + 10c = 1076
6*96 + 10*50 = 1076
576 + 500 = 1076

The monthly credit card payment would be $511.11, which is lower than the monthly payment on the bank loan.
The monthly payment on a bank loan would be $480, which is lower than the monthly credit card payment.
The monthly payment on a bank loan would be $551.11, which is lower than the monthly credit card payment.
The monthly credit card payment would be $540.78, which is lower than the monthly payment on the bank loan.
Answer: The monthly payment on a bank loan would be $480, which is lower than the monthly credit card payment.
To calculate the monthly payment on the bank loan, we can use the formula:
monthly payment = P * (r / (1 - (1 + r)^(-n)))
where P is the total loan amount, r is the annual interest rate as a decimal, and n is the number of months of the loan.
For a loan of $16,000 at 8% interest for 3 years (36 months)
r = 0.08/12 = 0.0067
n = 36
P = 16000
So, the monthly payment = 16000 * (0.0067 / (1 - (1 + 0.0067)^(-36))) = 480
To calculate the monthly credit card payment, we can use the formula:
M = P * r * (1 + r)^n / [(1 + r)^n - 1]
where P is the total loan amount, r is the monthly interest rate, and n is the number of months of the loan.
For a credit card with an annual rate of 15% for 7 years (84 months)
r = 0.15/12 = 0.0125
n = 84
P = 16000
So, the monthly payment = 16000 * 0.0125 * (1 + 0.0125)^84 / [(1 + 0.0125)^84 - 1] = 511.11
As we can see the monthly payment on the bank loan is lower than the monthly credit card payment. So, the correct answer is "The monthly payment on a bank loan would be $480, which is lower than the monthly credit card payment."

x + 47.5° + 93° = 180°
x + 140.5 = 180° {subtract 140.5° from both sides}
x = 180° - 140.5°
x = 39.5°
Therefore, the new value for the first angle 115.1° that will make the angle measures form a triangle is 39.5°

What are exponents?Exponents is the term used to describe a way to represent huge numbers using powers. In other words, the exponential describes how many times a number has been multiplied by itself. Various rules of exponents are presented according to the capacities they possess.
The following rule governs multiplication: Add the exponents while maintaining the base's consistency.
When bases are raised by a power of two or more, multiply the exponents while maintaining the original base.
Division Rule: When dividing like bases, take the exponent of the denominator and divide it by the exponent of the numerator, keeping the exponential base constant.
