What is The difference of 3-3÷2

After scoring 77, 87, and 74 on her previous three tests, Amy needs to score 66 on her next test in order to have an average of 76.

To find the score that Amy needs on her next test to have an average of 76, we need to use the formula for the mean of a set of numbers:
Mean = (Sum of all numbers) / (Total number of numbers)

We know that Amy's current scores are 77, 87, and 74, and we want her average to be 76. Let's call the score she needs on her next test "x".
So, we can plug these values into the formula:
76 = (77 + 87 + 74 + x) / 4

Now, we just need to solve for x:
76 * 4 = 77 + 87 + 74 + x
304 = 238 + x
x = 304 - 238
x = 66

So, Amy needs to score a 66 on her next test in order to have an average of 76.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol %.

Jessica :

8 yards of fabric

15% of 8  = (15/100)*8 = 1.2

Total fabric = 8 + 1.2 = 9.2  yards  

Derek :

4 yards of fabric

20% of 4  = (20/100)*4 = 0.8

Total fabric = 4 + 0.8 = 4.8  yards  

Jessica bought more fabric .

9.2 - 4.8  = 4.4 yards of fabric more

To find the set of parametric equations for the rectangular equation y = 3x - 4, we need to express x and y in terms of a parameter, say t. Let us assume that t = 0 at the point (4, 8).

First, we can write x in terms of t as x = 4 + at, where a is some constant. To find the value of a, we can use the fact that y = 3x - 4. Substituting x = 4 + at in this equation, we get y = 3(4 + at) - 4 = 12 + 3at. So, the set of parametric equations for y and x are:

x = 4 + at
y = 12 + 3at

Note that these parametric equations are not unique. We could have chosen a different parameterization, say t = 1 at the point (4,8), and obtained a different set of parametric equations. However, the given condition specifies the starting point and therefore determines the parameterization.

In summary, we can find a set of parametric equations for a rectangular equation by expressing x and y in terms of a parameter, using the given condition to determine the starting point, and choosing a suitable parameterization.

Given data

64^1/2 x 27000^2/3 all over2^-4 x 3^0 x 5^2

Rewriting gives:

( 64^1/2 x 27000^2/3 ) / ( 2^-4 x 3^0 x 5^2 )

the solution; we first note that

64^1/2 = √64 = 8

27000^2/3 = ∛27000^2 = 900

3^0 = 1

2^-4 = 1 / 2^4 = 1 / 32

5^2 = 25

substituting gives:

= ( 8 * 900 ) / ( 1/32 * 1 * 25)

= 7200 / 25/32

= 7200/25 * 32

= 288 * 32

f(x) and g(x) are not closed under subtraction because when subtracted, the result will be a polynomial, the correct option is B.

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.

Given f(x) and  g(x) two polynomial functions in the standard form of the polynomial,

According to Closure Property, when something is closed, the output will be the same as the input.

The polynomials f(x) and g(x) can be seen in the image.

On subtracting the two polynomials, the output will be a polynomial and so it is closed under subtraction.

Therefore, The reason why f(x) and g(x) are not closed under subtraction is that the outcome of subtraction will be a polynomial, making option B the best choice.

Answer:

The area of the shaded polygon is 31 square units.

Step-by-step explanation:

The procedure to calculate the area of the shaded irregular polygon is described below:

1) Calculate the area of the initial rectangle.

2) Calculate the areas of the four triangles.

3) Subtract the areas of the four triangles from the initial triangle.

\(A = (9)\cdot (6) - \frac{1}{2}\cdot (4)^{2} - \frac{1}{2}\cdot (5)\cdot (2) - \frac{1}{2}\cdot (2)^{2} - \frac{1}{2}\cdot (4)^{2}\)

\(A = 31\)

The area of the shaded polygon is 31 square units.

20 different pizzas

==========================================================

Explanation:

Consider 3 slots to fill. I'll label them slot A, B, C.

There are 6 choices for slot A, then 5 choices for B, and 4 for C. We count down by one each time since we cannot reuse a topping.

There would be 6*5*4 = 30*4 = 120 permutations if order mattered.

However, order doesn't matter with pizza toppings. So we must divide by 3*2*1 = 6 (this is the number of ways to arrange any group of 3 things)

We get 120/6 = 20 as the final answer

---------------------

Alternatively, you can use the nCr combination formula following these steps.

n C r = (n!)/(r!(n-r)!)

6 C 3 = (6!)/(3!*(6-3)!)

6 C 3 = (6!)/(3!*3!)

6 C 3 = (6*5*4*3!)/(3!*3!)

6 C 3 = (6*5*4)/(3!)

6 C 3 = (6*5*4)/(3*2*1)

6 C 3 = (120)/(6)

6 C 3 = 20 different pizzas possible

As the third to the last line shows, we have 6*5*4 up top and 3*2*1 down below. This matches exactly what was discussed in the previous section.

The required inequality is y ≥ - 0.6x + 45 which represents the number of hours Samir could work to earn enough to buy the game system. which is the correct answer would be an option (A).

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The video game system will cost at least $450.

He earns $6 per hour babysitting and $10 per hour tutoring.

Let x be the number of hours babysitting and y be the number of hours of tutoring.

According to the given situation, we can write the inequality would be as:

⇒ 6x + 10y ≥ 450

Rearrange the terms of variables in the above inequality,

⇒ 10y ≥ 450 - 6x

Divided by 10 into both sides of the above inequality,

⇒ 10y/10 ≥ 450/10 - 6x/10

⇒ y ≥ 45 - 0.6x or

⇒ y ≥ - 0.6x + 45

Thus, the required inequality is y ≥ - 0.6x + 45 which represents the number of hours Samir could work to earn enough to buy the game system.

Answer:

Given:

time taken by first pipe = 15 hours

time taken by second pipe = 5 hours

time taken by all three pipes together = 3 hours

work rates of pipes are :

1st pipe = 1/15

2nd pipe = 1/5

3rd pipe = 1/x

all together = 1/3

sum of individual rates = rate when all pipes are working together

1/15 + 1/5 + 1/x = 1/3

1/x = 1/3 - 1/15 - 1/5

solving the equation, we get
1/x = 1/ 15

x= 15

hence, it would take 15 hours for the third pipe to fill the tank.

a) Jay will consume 50 barrels of beer.b) Jay will spend $2500 on beer.c) Jay's consumer surplus from beer consumption is $1250 where demand function is given.

a) To determine how many barrels of beer Jay will consume at a price of $50 per barrel, we can substitute this price into his demand function:

D(p) = 100 - p

D(50) = 100 - 50

D(50) = 50

Therefore, Jay will consume 50 barrels of beer.

b) To calculate how much money Jay will spend on beer, we multiply the price per barrel by the quantity consumed:

Money spent on beer = Price per barrel * Quantity consumed

Money spent on beer = $50 * 50

Money spent on beer = $2500

Jay will spend $2500 on beer.

c) The consumer surplus represents the difference between the maximum price a consumer is willing to pay and the actual price paid. In this case, Jay's consumer surplus can be calculated by finding the area of the triangle formed by the demand curve and the price axis. Since Jay's demand function is a straight line, the consumer surplus can be calculated as:

Consumer surplus = (1/2) * (Quantity consumed) * (Price per barrel)

Consumer surplus = (1/2) * 50 * $50

Consumer surplus = $1250

Jay's consumer surplus from beer consumption is $1250.

The false statement is: "They go through routine diagnostic tests such as colonoscopies."

Routine diagnostic tests such as colonoscopies are typically recommended for individuals over the age of 50 as a preventive measure against colon cancer. People between the ages of 18 and 25 are generally not advised to undergo such tests unless they have specific risk factors or symptoms. It is important to note that there may be exceptions in certain cases, but colonoscopies are not typically considered routine for this age group.

On the other hand, the other statements are generally true for people between 18 and 25. Diet and exercise practices tend to improve during this time period as young adults become more conscious of their health and adopt healthier lifestyles. Death from disease is rare at this age due to the overall good health of young adults. Additionally, it is possible for some people to outgrow childhood ailments like asthma as they reach young adulthood, although this varies from person to person.

In summary, while diet and exercise practices tend to improve and death from disease is rare during the ages of 18 to 25, routine diagnostic tests such as colonoscopies are not typically performed during this time period.
