The integer rule.
Rule: When a positive number is being subtracted by a negative number, the negative number changes to a positive.
Implying the rule:
\(1 \frac{2}{3} + 5 \frac{2}{3}\)
Add:
\(1 \frac{2}{3} + 5 \frac{2}{3} = 7 \frac{1}{3} \)

The amount of cases in Gotham city is 540
people for the first 12 of 2020. In July, a spike at the rate
of 5.2 people for each day in the month hits. Additionally, the
joker has infected all of Arkham Asylum's 225 patients with the
virus. What month will you hit 1,000 cases of cases in Gotham?
Answer: October, the 10th month
Step-by-step explanation:
540/12 = 45[with this in mind , we can assume that this is how many people get infected per month, except for July, and some factors.]
July is special for it not only has the specific unqiue rate of 5.2 infections per day. with this in mind, lets multiply....
5.2 x 31 = 161.2And to top it off, we have another 225 infections to consider.
So with consideration of 161.2, 225, 540, and the fact that 45 people get infected on an average month, lets add....
161.2 + 225 + 540 = 926.2
926.2 + 45 = 971.2
971.2 + 45 = 1016.2
It only took until the 10th month of october to hit 1000.

Determine the number of ways to distribute 10 orange drinks, 1 lemon drink, and 1 lime drink to four thirsty students so that each student gets at least one drink, and the lemon and lime drinks go to different students.
Answer:
each student gets 3 drinks, make sure the lemon and lime are in different groupings
Step-by-step explanation:
The number of ways to distribute will be 1980.
What is permutation?
The permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters.
We have,
10 orange drinks
1 lemon drink, and
1 lime drink
And,
Four thirsty students,
Now,
According to the question,
We have to distribute that each student gets at least one drink, and the lemon and lime drinks go to different students.
So,
Using the permutation formula,
Permutation (ⁿPr) = n!/(n-r)!
⁴P₂ = 4! / (4-2)! = (4 × 3 × 2!) / 2! = 4 × 3 = 12
Now,
Using the Combination formula,
Combination (ⁿCr) = n! / [r! (n-r)!]
So,
(ⁿCr) = n! / [r! (n-r)!]
¹¹C₃ = 11! / [ 3!(11-3)!] = [11 × 10 × 9 × 8!] / [ 3 × 2 × 1 × 8!]
¹¹C₃ = 11 × 5 × 3 = 165
So,
The number of ways to distribute = 12 × 165 = 1980
Hence we can say that he number of ways to distribute will be 1980.

Using only addition and multiplication, combine the single -digit numbers 1,2,3,4,5,6,7,8,9. So they total 100. the number must stay in the same order (Parentheses are not needed)
It is not possible to find a combination using addition and multiplication of the given single-digit numbers that totals exactly 100 while keeping the same order.
To combine the single-digit numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 using only addition and multiplication so that they total 100 while keeping the same order, we can form the following expression:
1 + 2 + 3 + 4 + 5 + 6 + 78 + 9
In this expression, we group the numbers 7 and 8 together to form 78. Then, we add all the other numbers from 1 to 6 and the number 9. Adding them up, we get:
1 + 2 + 3 + 4 + 5 + 6 + 78 + 9 = 108
Unfortunately, the sum obtained from this expression is 108, not 100 as required.
It is not possible to obtain a sum of exactly 100 by combining the single-digit numbers 1 to 9 in the given order using only addition and multiplication. This is because the largest single-digit number, 9, is relatively small compared to the desired total of 100.
Adding all the single-digit numbers in order without any multiplication would result in a sum of 45, which is significantly lower than 100. Multiplication can only further decrease the sum, making it even more difficult to reach 100.

Identify the explanatory variable and the response variableA golfer wants to determine if the amount of practice every year can be used to predict the amount of improvement in his game.The explanatory variable is the _____The response variable is the _____
Answer:
the explanatory variable is "the amount of practice every year" while the response variable is "the improvement in his game"
Step-by-step explanation:
In simple terms, the difference between explanatory and random variable is that the response variable is usually the focus of a question in a study/experiment while an explanatory variable is a variable that explains changes in the response variable. Which means that the explanatory variable is simply any variable that may affect the response variable.
Now, in this question, the golfer wants to determine if the amount of practice every year can be used to predict the amount of improvement in his game.
This means that the amount of practice every year explains how much he improves every year.
Thus, the explanatory variable is "the amount of practice every year" while the response variable is "improvement in his game"
Solve for the unknown in the following diagram. Round the answer to two decimal places.
degrees
Answer:
x = 63.28°
Step-by-step explanation:
A = 33°
a = 175 mm
C = x
c = 287 mm
Use the Law of Sines to find x
Thus:
\( \frac{a}{sin(A)} = \frac{c}{sin(C)} \)
Plug in the values
\( \frac{175}{sin(33)} = \frac{287}{sin(x)} \)
Cross multiply
\( 175*sin(x) = 287*sin(33) \)
Divide both sides by 175
\( sin(x) = \frac{287*sin(33)}{175} \)
\( sin(x) = 0.893208017 \)
\( x = sin^{-1}(0.893208017) \)
x = 63.28° (2 decimal places)

Which expression is equival 81 1/3?
Answer: 3^3 Square root 3
Step-by-step explanation:
Consider the following function. x6 1 + x2 dx (a) Determine an appropriate trigonometric substitution. Use x = sin(θ), where − π 2 ≤ θ ≤ π 2 , since the integrand contains the expression 1 + x2 . Use x = tan(θ), where − π 2 < θ < π 2 , since the integrand contains the expression 1 + x2 . Use x = sec(θ), where 0 ≤ θ < π 2 or π ≤ θ < 3π 2 , since the integrand contains the expression 1 + x2 . (b) Apply the substitution to transform the integral into a trigonometric integral. Do not evaluate the integral. x6 1 + x2 dx = dθ
Answer:
Step-by-step explanation:
In the first part, we are given the function:
\(\int \dfrac{x^6}{\sqrt{1+x}^2} \ dx\)
Suppose we make x = tan θ
Then dx = sec² θ.dθ
\(= \int \dfrac{tan^6 (\theta)}{\sqrt{1+ tan ^2 \theta }}* dx\)
\(= \int \dfrac{tan^6 (\theta)}{\sqrt{1+ tan ^2 \theta }}* sec ^2 (\theta) * d\theta\)
Since; sec² θ - tan² θ = 1
sec² θ = 1+ tan² θ
\(sec \ \theta = \sqrt{1 + tan^2 \ \theta}\)
∴
\(= \int \dfrac{tan^6 (\theta)}{sec \ \theta}* sec ^2 (\theta) * d\theta\)
\(= \int tan^6 (\theta)* sec (\theta) * d\theta\)
Thus; In the first part, Use x = tan θ, where \(- \dfrac{\pi}{2} < \theta <\dfrac{\pi}{2}\), since the integrand comprise the expression \(\sqrt{1+x^2}\)
From the second part by using substitution method;
\(\int \dfrac{x^6}{\sqrt{1+x^2}} \ dx = \int \mathbf{tan^6(\theta) * sec ( \theta) } \ d \theta\)

Therefore, Antonio served a total of 28 1/2 ounces of chicken that is option D. Therefore, the total weight of the packages that the mail carrier delivered was 51.5 pounds. Therefore, Pam used 4 1/2 gallons of paint to paint her bedroom, or 4.5 gallons if we convert the fraction to a mixed number that is option C.
What is fraction?A fraction is a way of expressing a part of a whole or a ratio between two numbers. A fraction consists of two numbers separated by a horizontal or diagonal line. The number above the line is called the numerator, and the number below the line is called the denominator.
Here,
8. Antonio is serving himself and 5 friends, so the total number of people he is serving is 1 + 5 = 6.
He serves each person a 4 3/4 ounce piece of chicken, which is equivalent to 4.75 ounces.
To find the total amount of chicken he served, we can multiply the number of people by the amount of chicken each person received:
Total amount of chicken = Number of people x Amount of chicken per person
Total amount of chicken = 6 x 4.75
Total amount of chicken = 28 1/2 pounds
9. The mail carrier delivered 8 packages in total. Let's first find the total weight of the packages that weighed 4 2/3 pounds each:
Weight of one package = 4 2/3 = 14/3 pounds
Total weight of three packages = 3 x 14/3 = 42/3 = 14 pounds
Next, let's find the total weight of the packages that weighed 7 1/2 pounds each:
Weight of one package = 7 1/2 = 15/2 pounds
Number of packages = 8 - 3 = 5
Total weight of five packages = 5 x 15/2 = 75/2 = 37.5 pounds
Finally, we can find the total weight of all 8 packages by adding the weight of the two groups of packages:
Total weight = Weight of packages that weighed 4 2/3 pounds each + Weight of packages that weighed 7 1/2 pounds each
Total weight = 14 + 37.5
Total weight = 51.5 pounds
10. Pam found 5 5/8 gallons of paint in the garage. She used 4/5 of the paint to paint her bedroom. To find out how many gallons of paint she used to paint her bedroom, we need to multiply the total amount of paint by 4/5:
Amount of paint used = 5 5/8 x 4/5
To make the calculation easier, we can convert the mixed number to an improper fraction:
5 5/8 = (8 x 5 + 5)/8
= 45/8
Now we can substitute this into the formula:
Amount of paint used = 45/8 x 4/5
Amount of paint used = 180/40
We can simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 20:
Amount of paint used = (180/20) / (40/20)
Amount of paint used = 9/2

Step-by-step explanation:
to find the y values, plug in the given x values into the equation y= 4x+7
when x = 0
y = 4(0) + 7
y = 0 + 7
y = 7
so the y value that corresponds to the x value 0 is 7 which is also written as (0,7)
when x = 1
y = 4(1) + 7
y = 4 + 7
y = 11
so the y value that corresponds to the x value 1 is 11; also written as (1, 11)
when x = 2
y = 4(2) + 7
y = 8 + 7
y = 15
so the x value 2 corresponds to the y value 15; also written as (2 , 15)

The basic rate pay is K8.20. If the overtime is paid at time-and-a-quarter, what is the overtime rate of pay?
The overtime rate of pay is K10.25.
The overtime rate of pay can be calculated by multiplying the basic rate pay by the time-and-a-quarter factor. In this case, the basic rate pay is K8.20.
To determine the overtime rate of pay, we need to calculate one-quarter (1/4) of the basic rate pay, and then add that amount to the basic rate pay. One-quarter of K8.20 is calculated as (1/4) * K8.20 = K2.05.
By adding the calculated overtime amount to the basic rate pay, we get the overtime rate of pay: K8.20 + K2.05 = K10.25.
Therefore, the overtime rate of pay is K10.25.

Ringani worked overtime to raise a total amount R30 000.00 to settle his student debt. If he has deposited R8 500.00 yearly into an account earning 7,04% interest per year compounded annually. How long, rounded to one decimal place did it took her to accumulate the total amount? A. 3.0 years B. 2.4 years C. 2.8 years D. 2.0 years
It took Ringani 2.8 years to accumulate the total amount of R30,000.00 by depositing R8,500.00 yearly into the account with a 7.04% interest rate Compounded annually.The correct answer choice is C. 2.8 years.
To determine how long it took Ringani to accumulate the total amount of R30,000.00 by depositing R8,500.00 yearly into an account with a 7.04% interest rate compounded annually, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the final amount
P is the principal amount (initial deposit)
r is the interest rate (in decimal form)
n is the number of times the interest is compounded per year
t is the time in years
In this case, we have:
P = R8,500.00
A = R30,000.00
r = 7.04% = 0.0704 (in decimal form)
n = 1 (compounded annually)
We want to find the value of t.
Using the formula, we can rearrange it to solve for t:
t = (log(A/P)) / (n * log(1 + r/n))
Substituting the given values, we have:
t = (log(30,000/8,500)) / (1 * log(1 + 0.0704/1))
Calculating this using a calculator, we find that t is approximately 2.8 years.
Therefore, it took Ringani approximately 2.8 years (rounded to one decimal place) to accumulate the total amount of R30,000.00 by depositing R8,500.00 yearly into the account with a 7.04% interest rate compounded annually.
The correct answer choice is C. 2.8 years.
