a textbook store sold a combined total of 366 psychology and history textbooks in a week. The number of history textbooks sold was 40 less than the number of psychology textbooks sold. how many textbooks of each type were sold?
Answer:
Step-by-step explanation:
We have two types of textbooks. Let's use "x" to represent the number of math textbooks and "y" to represent the number of history textbooks.
Altogether, the bookseller sold 240 math and history textbooks. So:
x + y = 240
Now, the number of history textbooks sold was 72 less than the number of math books sold. So:
y = x - 72
Now we can substitute for y in the equation and solve:
x + y = 240
x + (x - 72) = 240
2x - 72 = 240
2x = 312
x = 156
The bookseller sold 156 math textbooks.
Since y = x - 72, he must have sold 84 history textbooks.
Let's check our answers:
x + y = 240
156 + 84 = 240
That is true, so we did get the correct answers

What are fractions?fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. In proper fractions the denominator is greater than the numerator but in improper, the denominator is lesser than the numerator.
Chung read 5/8 of a book
let's represents the volume pages of the book by x
therefore chung read 5/8 × x = 5x/8
on the second day, he read 1/5 less of the previous day = 5x/8-1/5x = 17x/40 i.e he read 17/40 of the book on the second day
the volume of pages left = x - (17×/40+5×/8)
x-22x/40
the fraction of remaining page left = (40-22)x/40
= 28x/40
divide through by 4
7/10 of x
therefore 7/10 of the book is still left to be read. This means chung didn't finish reading the book on the second day.

3) Suppose you finance a car in the amount of $28,550. The loan is for 7 years with an APR of
8%. What will be the payoff balance of this car loan after 4 years?
The
Answer:
So the payoff balance of the car loan after 4 years will be approximately $22,169.73.
Step-by-step explanation:
payoff balance after 4 years can be calculated using the following formula:
Payoff balance = Principal * (1 + APR/n)^(nt) - [(Principal * (1 + APR/n)^(nt) * (APR/n)) / (1 + APR/n - 1)]
Where:
Principal is the loan amount, which is $28,550 in this case.
APR is the annual percentage rate, which is 8% in this case.n is the number of times per year that interest is compounded, which is usually 12 for monthly compounding.t is the number of years for which the loan is taken, which is 4 years in this case.
Plugging in the values, we get:
Payoff balance = $28,550 * (1 + 0.08/12)^(124) - [($28,550 * (1 + 0.08/12)^(124) * (0.08/12)) / (1 + 0.08/12 - 1)]
Payoff balance = $28,550 * 1.006669^48 - [$28,550 * 1.006669^48 * 0.006669] / 0.006669Payoff balance = $22,169.73

7x+2≥30 or 2x-3≤-11 PLEASE HELP I HAVE 2 HOURS
Answer:
Therefore, the correct solution graph for the inequality is a line with no solution. This means that there is no value of x that satisfies both inequalities at the same time.
Step-by-step explanation:
To solve this inequality, we need to consider the two separate cases of 7x+2≥30 and 2x-3≤-11 separately.For the first case, 7x+2≥30, we can rewrite the inequality as 7x≥28, which simplifies to x≥4. This means that the solution for this inequality is x≥4.For the second case, 2x-3≤-11, we can rewrite the inequality as 2x≤-8, which simplifies to x≤-4. This means that the solution for this inequality is x≤-4.To find the combined solution for both inequalities, we need to take the intersection of these two solutions. The intersection of x≥4 and x≤-4 is the empty set, which means that there is no solution that satisfies both inequalities

b) The growth rate percent is 102.5 %
c) It would attain the value in 11 years.
What is a function?We know that a function has to do with a mathematical rule that is used for the establishment of a fact. We have from the question that the function that models the car is; V = 2000000(1.025)^n
Let us recall that n has to do with the number of years.
a) In four years, the value of the car would be;
V = 2000000(1.025)^4
V = 2,207,626
b) The growth rate percent of the function can be obtained as;
1.025 * 100 = 102.5 %
c) To obtain the year in which the value of the car would reach 2624173.32, we have;
2624173.32 = 2000000(1.025)^n
2624173.32/2000000 = (1.025)^n
1.312 = (1.025)^n

Answer:
3x +3
Step-by-step explanation:
You want to simplify 2x+ (9+x) -6.
Like termsLike terms have the same constellation of variables. Here, there are terms containing x, and terms not containing x.
2x+ (9+x) -6 = (2 +1)x +(9 -6) = 3x +3
The simplified expression is 3x +3.
Answer:3x+3
Step-by-step explanation:
First we remove the parenthesis because they are not needed in an addition problem to make it 2x+9+x-6
Then we sort and combine like terms, [2x+x]+[9-6]
After that, you add the coefficients of the the first term, which makes 3x and subtract 6 from 9 to get 3

Diane has quarters, dimes, and
pennies in her pocket. The value of her
money is $1.55. There are 4 more
dimes than quarters and the number of
pennies equals the sum of the number
of quarters and dimes.
How many pennies does Diane have?
Answer: The solution here is found by establishing a system of linear equations.
A system of equations with x unknowns can be evaluated for an exact solution if the system has x equations.
Within the question, we are asked to discover the values of two different unknowns - dimes and nickels.
Therefore, we'll need two equations to obtain an exact solution, both of these will come directly from the problem itself.
Let d represent the number of dimes Diane has and let n represent the number of nickels.
Equation 1
We know from the given information that the total number of coins (both dimes and nickels) is equal to 19.
Subsequently, we can generate the equation d + n = 19.
Equation 2
We know that the individual value of a dime is $0.10 or 0.1 dollars, therefore the total value of the dimes is equal to the individual value of a dime multiplied by the total number of dimes.
The resultant expression for the total value of the dimes is (0.1)*d
We know that the individual value of a nickel is $0.05 or 0.05 dollars, therefore the total value of the nickels is equal to the individual value of a nickel multiplied by the total number of nickels.
The resultant expression for the total value of the nickels is (0.05)*n
We know that Diane only has dimes and nickels, and the total value of all her coins must be equal to the total value of the dimes plus the total value of the nickels. This value is given within the problem to be $1.55 or 1.55 dollars.
Subsequently, our second equation within the system is (0.1)*d + (0.05)*n = 1.55.
Now, we can solve the system of equations using whichever means is most convenient. For this example, I will solve the system by substitution
First, solve for one of the variables —> Equation 1 —> d + n = 19 —> d = 19 - n
Second, substitute the value of d into Equation 2 —> (0.1)*(19 - n) + (0.05)*n = 1.55
Recall that 0.1 = 1/10 and 0.05 = 1/20
Equation 2 —> (1/10)*19 - (1/10)*n + (1/20)*n = (31/20) —> (19/10) - (n/10) + (n/20) = (31/20)
Find the least common denominator of all fractions in the equation (20 in this case), convert the fractions to have like denominators, and solve.
(19/10)*(2/2) - (n/10)*(2/2) + (n/20) = (31/20) —> (38/20) - (2n/20) + (n/20) = (31/20) —> (38/20) - (n/20) = (31/20) —> (n/20) =(38/20) - (31/20) =(7/20) —>n = 7
Substitute solution into Equation 1 to solve for d
d + 7 = 19 —> d = 12
q+4+q + 10q+40 + 25q = 155
37q + 44 = 155
37q = 111
q = 3 (# of quarters)
d = q+4 = 7 (# of dimes)
p = d+q = 7+3 = 10 (# of pennies)

3. suppose that a particular nfl team claims that the mean weight of their defensive players is 315 pounds. a rivaling team thinks that the mean weight of the defensive players on that team is different from 315 pounds they claim. suppose they sample 15 of the defensive players and find the players to have a mean weight of 300 pounds with sample standard deviation 8 pounds. set up an appropriate hypothesis test and make conclusions at significance level 0.08. assume weights are normally distributed.
The appropriate hypothesis test results that it reject the null hypothesis and accept the alternative hypothesis. The z score of -7.26 is in the rejection area
How to calculate hypothesis test?
The general form to calculate the hypothesis is by using the sample data and assuming the null hypothesis is true, calculate the value of the test statistic.
Here the hypothesis test for the population mean μ, we use the t-statistic t = x − (μ*s) / n
where the t-distribution with n - 1 degrees of freedom.
Here we have given that suppose that a particular NFL team claims that the mean weight of their defensive players is 315 pounds.
And we need to find appropriate hypothesis test and make conclusions at significance level 0.08 and here we have to assume weights are normally distributed.
While we looking into the given question, we have identified that weights are normally distributed.
Then the value of the given data are written as
data = 315 ,
n= 15 ,
Mean = 300,
standard deviation = 8,
Significance level= 0.08
Then the hypothesis is written as,
The critical value (cutoff point) is 1.761.
Where in left-tail hypothesis testing, any z score less than the critical value will be rejected. Since -7.26 is less than 1.761, we reject the null hypothesis. We accept the alternative hypothesis

assume victoria's indifference curves are bowed outward but her indifference curves satisfy the other three properties of indifference curves. as victoria moves from right to left along the horizontal axis, her marginal rate of substitution
The marginal rate of substitution (MRS) is a measure of how much of one good an individual is willing to give up in exchange for another good. In other words, it represents the slope of the indifference curve at a given point.
If Victoria's indifference curves are bowed outward, it means that as she moves from right to left along the horizontal axis, the MRS will decrease. This is because as she consumes more of one good, she becomes less willing to give up units of the other good in exchange. The MRS will continue to decrease until it reaches its minimum value at the point where the indifference curve is tangent to the budget line.
It's important to note that the MRS will only decrease if Victoria's indifference curves satisfy the other three properties of indifference curves:
Higher indifference curves represent a higher level of utility.Indifference curves do not intersect.Indifference curves are downward sloping.If Victoria's indifference curves do not satisfy these properties, it is not possible to accurately determine the behavior of her MRS as she moves from right to left along the horizontal axis.
