Using equations, we can find that the total cards sold on Mother's Day = 1100.
What are equations?Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. It is demonstrated that the expressions on the left and right are equivalent to one another.
In all mathematical equations, LHS = RHS (left hand side = right hand side) is a constant. The value of an unknown variable, or unknown quantity, can be determined through solving equations.
Here,
Let the total no. of cards sold be = x
Now 2% of cards sold = 22
We can say, 2% of x = 22
⇒ 2/100 × x = 22
⇒ x = (22 × 100)/2
⇒ x = 1100
Therefore, the total number of cards sold on Mother's Day = 1100.

What is the difference between expression and equation?
An expression is a mathematical phrase that contains numbers, variables, and operations. It can be evaluated to produce a single numerical value or another expression. Expressions do not contain an equal sign (=), and they do not represent a statement that is either true or false.
An equation, on the other hand, is a mathematical statement that shows the equality between two expressions. It contains an equal sign (=) and represents a statement that is either true or false. Equations typically contain variables that can take on different values, and they can be used to solve for an unknown variable by manipulating the equation using algebraic operations.
To summarize, expressions are mathematical phrases that do not contain an equal sign and can be evaluated to produce a value, while equations are mathematical statements that do contain an equal sign and represent a relationship between two expressions that is either true or false.
We can use addition to represent the total number of almonds that Daniel snacked on. If Daniel snacked on an initial amount of almonds, say "a", and then snacked on an additional 8 almonds, we can write the expression:

A company estimates that 0.8% of their products will fail after the original warranty period but within 2 years of the purchase, with a replacement cost of $300.
If they offer a 2-year extended warranty for $47, what is the company's expected value of each warranty sold? Round your answer to the nearest cent.
Answers
Answer: The expected value of each warranty sold can be calculated as the sum of the product of the probability of a product failing after the original warranty period and the replacement cost, and the cost of the extended warranty:
Expected value = (0.8% of $300) + ($47)
Expected value = (0.008)($300) + ($47)
Expected value = $2.40 + $47
Expected value = $49.40
Therefore, the company's expected value of each warranty sold is $49.40.

We can use the future value formula for an annuity to solve this problem:
FV = PMT * ((1 + r)^n - 1) / r
where:
FV is the future value of the annuity
PMT is the regular payment or deposit
r is the annual interest rate
n is the number of periods (in this case, the number of years)
We want to solve for PMT, so we can rearrange the formula to get:
PMT = FV * r / ((1 + r)^n - 1)
Plugging in the given values, we get:
FV = $80,000
r = 6% = 0.06
n = 15 years
So, the annual deposit required is:
PMT = $80,000 * 0.06 / ((1 + 0.06)^15 - 1) ≈ $3,782.58
Therefore, the man would need to deposit approximately $3,782.58 into the account each year in order to have $80,000 saved up for his granddaughter's college education in 15 years, assuming a 6% return.

The cafeteria makes peanut butter and jelly sandwiches on Wednesday. There are 4 1/2 cups in one jar of peanut butter. There are 3 1/3 cups in one jar of jelly. At the end of the day the cafeteria has used 3 1/2 jars of peanut butter and 2 1/6 jars of jelly. How many cups of peanut butter has the cafeteria used?
Answers
Answer: 15 3/4 cups
In order to figure out how much peanut butter they have used we must multiply our amount by the number used.
4 1/2 times 3 1/2 can also be written as 4.5 and 3.5, respectively.
So our equation would be 4.5 x 3.5
4.5 x 3.5 is 15.75
The number .75 can be written as the fraction 3/4, since 75 is 3/4th of 100.
This means the cafeteria used 15 3/4 cups of peanut butter.
I hope this helped & Good Luck <3 !!!
To calculate the amount of peanut butter used, multiply the number of jars (3 1/2) by the quantity in each jar (4 1/2 cups). This equals 15 3/4 cups of peanut butter.
Explanation:To find out how many cups of peanut butter the cafeteria has used, we need to multiply the number of jars used by the number of cups in each jar. We know that there are 4 1/2 cups in one jar of peanut butter and the cafeteria has used 3 1/2 jars. So, we multiply 4 1/2 by 3 1/2 to get the total number of cups used.
This can be done by converting the mixed fractions to improper fractions: 4 1/2 becomes 9/2 and 3 1/2 becomes 7/2. Multiplying these gives 63/4, which converts back to the mixed number 15 3/4.
So, the cafeteria has used 15 3/4 cups of peanut butter.

What is the average number of siblings for this group?
Enter your answer as a decimal, rounded to the nearest tenth, in the blank.
Answers
Answer:
1.3
Step-by-step explanation:
To find the average number of siblings for the group, we need to calculate the total number of siblings and divide by the total number of children.
Out of the 15 children:
5 are only children, so they have 0 siblings each.
3 have 1 sibling each, so there are 3 * 1 = 3 siblings in total.
4 have 2 siblings each, so there are 4 * 2 = 8 siblings in total.
3 have 3 siblings each, so there are 3 * 3 = 9 siblings in total.
The total number of siblings is 0 + 3 + 8 + 9 = 20.
The average number of siblings for the group is 20/15 = 1.3 (rounded to the nearest tenth).
Therefore, the average number of siblings for this group is 1.3.

Pilots can make quick calculations by solving one-step equations. For instance: the distance in miles from the airport that a plane should begin descending, divided by 3, equals the plane's height above the ground in thousands of feet. If an aircraft is 10,000 feet above the ground, write and solve an equation to find the distance the pilot should begin descending.
Answers
Let d be the distance in miles from the airport that a plane should begin descending. According to the problem statement, we can write the equation:
d/3 = 10
To solve for d, we can isolate it by multiplying both sides of the equation by 3:
d = 3 * 10
Therefore, the pilot should begin descending when the plane is 30 miles from the airport.

The monthly payments are $248.53.
The total amount that he will pay $14911.8.
The amount of interest is $4911.8
What is the interest rate?
The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate. The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.
The formula of monthly payment is
P = [tex]\frac{r (PV)}{1-(1-r)^{-n}}[/tex]
r is the rate of interest.
PV is the present value
n is the number of terms.
The bank offers you an installment loan with an interest rate of 17% over a 60-month term. The cost of the car is $10,000.
PV = $10,000
n = 60
r = 17%/12 = 0.17/12
The monthly installment is
P = [tex]\frac{ \frac{0.17}{12}\times 10000}{1-(1- \frac{0.17}{12})^{-60}}[/tex]
P = 248.53
The monthly installment is $248.53.

Classify the triangle below as Right, Obtuse, or Acute
Answers
The triangles include:
4) Acute5) Obtuse6) Obtuse7) Right8) Right9) Obtuse10) ObtuseHow to classify triangles?
4) To determine if a triangle is right, obtuse, or acute, we need to use the Pythagorean Theorem to determine if the square of the longest side equals the sum of the squares of the other two sides.
Here, the longest side is 9, and the other two sides are 6 and 7.
9² = 6² + 7²
81 = 36 + 49
81 = 85
Since 81 is not equal to 85, the triangle is not a right triangle. To determine if it's obtuse or acute, we need to check the cosine of the largest angle using the Law of Cosines.
cos A = (b² + c² - a²) / 2bc
Let's choose 9 as side a, since it's the largest side:
cos A = (6² + 7² - 9²) / (84)
cos A = 0.048
Since cos A is positive, angle A is acute. Therefore, the triangle is acute.
5) Using the same process as above:
16² = 10² + 12²
256 = 100 + 144
256 = 244 + 12
Since 256 is greater than 244, the triangle is obtuse.
6) Again, using the same process as above:
(8√6)² = 8² + 16²
192 = 64 + 256
192 = 320
Since 192 is less than 320, the triangle is obtuse.
7) 29² = 20² + 21²
841 = 400 + 441
841 = 841
Since 841 is equal to 841, the triangle is a right triangle.
8) √73 is greater than 8 and 3, so it must be the largest side.
(√73)² = 8² + 3²
73 = 64 + 9
73 = 73
Since 73 is equal to 73, the triangle is a right triangle.
9) 12² = 8² + 10²
144 = 64 + 100
144 = 164 - 20
Since 144 is less than 164, the triangle is obtuse.
10) 15² = 9² + (3√34)²
225 = 81 + 306
225 = 387 - 162
Since 225 is less than 387, the triangle is obtuse.

Step-by-step explanation:
Cason wants to read at least 45 books. He has already read one book. If he reads 2 books a week, how many weeks will he need to read to meet his goal? Solve a linear inequality to find the number of weeks Cason must read.
A. x < 22
B. x > 22
C. x ≤ 22
D. x ≥ 22
I need an explanation to
Answers
Cason must read for at least 22 weeks to meet his goal. The correct answer is D. x ≥ 22
Solving by InequalityLet x be the number of weeks Cason needs to read to meet his goal. In each week, he can read 2 books. Therefore, the total number of books he will read in x weeks is:
2x
Since Cason has already read one book, the total number of books he will have read after x weeks is:
2x + 1
We want Cason to read at least 45 books, so we can set up an inequality:
2x + 1 ≥ 45
Subtracting 1 from both sides, we get:
2x ≥ 44
Dividing both sides by 2, we get:
x ≥ 22
Therefore, Cason must read for at least 22 weeks to meet his goal.

3x-1>-4 and -2x-3<1 in interval notation
Answers
This means that the solution is any x value that is less than -1 AND greater than -2.
What kind of notation is it?A good example of notation is musical notation. This kind of notation system can be used by a composer to instruct performers and listeners on how to play and hear their music. There are many different types of symbols and pictures in it.
To solve the inequality 3x - 1 > -4, we add 1 to both sides:
3x - 1 + 1 > -4 + 1
3x > -3
Then, we divide both sides by 3 (remembering to flip the inequality sign since we're dividing by a negative number):
x < -1
So the solution to 3x - 1 > -4 is x < -1.
To solve the inequality -2x - 3 < 1, we add 3 to both sides:
-2x - 3 + 3 < 1 + 3
-2x < 4
Then, we divide both sides by -2 (remembering to flip the inequality sign again):
x > -2
So the solution to -2x - 3 < 1 is x > -2.
Putting these two solutions together in interval notation, we get:
(-∞, -1) ∩ (-2, ∞)
This means that the solution is any x value that is less than -1 AND greater than -2.

Which could be the number Drew wrote?
Answers
The number that Drew wrote is 790,800.
What is number?Number is a mathematical object used to count, measure, and label. It is an abstract concept that can be represented with symbols, such as numerals, and words, such as "three" or "three hundred." Numbers can be used to represent quantities, distances, sizes, and other measurements. In mathematics, number theory is the study of the properties of numbers, such as addition, subtraction, multiplication, and division. Number theory is also used in other sciences, such as physics and computer science.
This is determined by taking the value of each digit and multiplying it by the exponential value that Drew described. The first digit has a value of 7 x 100,000, the second digit has a value of 9 x 100, and the third digit has a value of 8 x 0.01. Therefore, the number is 790,800.
