What is the value of 2\3 (-9+3)? represent your answer in the simplest form
Answer:
2/3 (-9+3) simplifies to 2/3 (-6) which is equal to -4.
Step-by-step explanation:
To simplify 2/3(-9+3), we need to start by simplifying the expression inside the parentheses, which is -9+3=-6. Therefore, we can rewrite the expression as 2/3(-6).
Now we can apply the distributive property of multiplication over addition/subtraction to simplify further. This property states that a(b+c) = ab + ac. So, 2/3(-6) can be written as:
2/3 x -6 = 2/3 x (-1 x 6) = 2/3 x (-1) x 6 = -2/3 x 6
Now we just need to multiply -2/3 by 6, which gives us -12/3 or -4. Therefore, 2/3(-9+3) simplifies to -4.

If you have a rectangle with a length of 5 and a width of 3, the area would be 5 * 3 = 15.
To factorise a quadratic equation, you need to find two numbers that multiply to give the constant term and add to give the coefficient of the x term.
For example, if you have the equation x^2 + 5x + 6 = 0, the two numbers you need to find are 2 and 3, because 2 * 3 = 6 and 2 + 3 = 5. So the equation can be factorised as (x + 2)(x + 3) = 0.

A school fundraising event sold a total of 223 tickets and generated a total revenue of $955.90 there are two types of tickets auto tickets and child tickets each adult ticket cost $6.60 and each child ticket cost $2.75. write and solve a system of equation to answer the following questions
____ adult tickets and ______child tickets were sold
A school fundraising event sold a total of 223 tickets and generated a total revenue of $955.90, 89 adult tickets and 134 child tickets were sold.
Let's use the following variables to represent the number of tickets sold:
a: the number of adult tickets soldc: the number of child tickets soldUsing this, we can write the following system of equations:
a + c = 223 (the total number of tickets sold is 223)
6.60a + 2.75c = 955.90 (the total revenue generated is $955.90)
To solve this system of equations, we can use any method of our choice, such as substitution or elimination. Here, we will use the elimination method:
Multiply the first equation by 2.75 to get 2.75a + 2.75c = 613.25Subtract the second equation from the above equation to get:(2.75a + 2.75c) - (6.60a + 2.75c) = 613.25 - 955.90
Simplify the above equation to get:-3.85a = -342.65
Solve for a to get a = 89Substitute a = 89 in the first equation to get c = 223 - 89 = 134Therefore, 89 adult tickets and 134 child tickets were sold during the fundraising event. We were given the total number of tickets sold and the total revenue generated by the school fundraising event. We used this information to set up a system of equations that describes the relationship between the number of adult tickets sold, the number of child tickets sold, and the total revenue generated. We solved this system of equations using the elimination method to find the number of adult and child tickets sold. The final answer is 89 adult tickets and 134 child tickets sold.

By the concept of vertically opposite angles, m∠MDH = 44°.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know, Pair of vertically opposite angles are equal.
Therefore, 2y + 130 = 3y + 127.
y = 3.
So, 2y + 130 = 136°
Again, ∠PDG = ∠MDH.
Now, 2∠PDG = 360° - 2(136°)

1. the altitudes of a triangle are the angle bisectors of the orthic triangle
2. the circle whose diameter is the side of the triangle passes through the opposite vertices of the orthic triangle
The altitudes of a triangle are the angle bisectors of the orthic triangle is true because the orthic triangle is formed by the feet of the altitudes of the original triangle. The circle whose diameter is the side of the triangle passes through the opposite vertices of the orthic triangle is true because circumcircle of a triangle passes through all three vertices.
To prove the first statement, we can use the fact that the altitudes of a triangle are perpendicular to the sides and intersect at the orthocenter. The orthic triangle is formed by the feet of the altitudes of the original triangle.
1. Let ABC be the original triangle and D, E, F be the feet of the altitudes from A, B, and C, respectively.
2. Since AD is an altitude, ∠ADB and ∠ADC are right angles.
3. Similarly, ∠BEC and ∠BFC are right angles.
4. Therefore, ∠BDC and ∠EDF are supplementary angles, meaning they add up to 180 degrees.
5. Since ∠BDC and ∠EDF are supplementary and they share a common side, they are also the angle bisectors of the orthic triangle DEF.
6. The same logic can be applied to the other two altitudes to show that they are also angle bisectors of the orthic triangle.
To prove the second statement, we can use the fact that the circumcircle of a triangle passes through all three vertices.
1. Let ABC be the original triangle and D, E, F be the feet of the altitudes from A, B, and C, respectively.
2. Let O be the circumcenter of the original triangle ABC.
3. Since the circumcircle passes through all three vertices, OD, OE, and OF are all radii of the circle.
4. Since all radii of a circle are equal, OD = OE = OF.
5. Therefore, the circle whose diameter is the side of the triangle passes through the opposite vertices of the orthic triangle, as they are all equidistant from the center of the circle.

The simple interest charged on a 4-month loan of \( \$ 12,000 \) is \( \$ 496 \). Find the simple interest rate. (Round your answer to one decimal place.) \( \% \)
The simple interest rate for this loan is 12.4%.
To find the simple interest rate, we can use the formula for simple interest, which is:
Simple Interest = Principal x Rate x Time
In this case, we are given the simple interest (\$496), the principal (\$12,000), and the time (4 months). We can plug these values into the formula and solve for the rate.
\$496 = \$12,000 x Rate x (4/12)
Simplifying the equation, we get:
\$496 = \$4,000 x Rate
Dividing both sides by \$4,000, we get:
Rate = 0.124
To convert this to a percentage and round to one decimal place, we multiply by 100 and round:
Rate = 0.124 x 100 = 12.4%
Therefore, the simple interest rate for this loan is 12.4%.

The greatest possible distance from Austin to san Antonio is 335.77 mi, b. the Least possible distance to Austin to san Antonio is 120.03 mi.
Describe Distance?
Distance refers to the physical length or space between two points or objects. It is an important concept in mathematics, physics, and everyday life. Distance can be measured in various units such as meters, feet, kilometers, miles, or light-years, depending on the context and scale of the measurement.
In mathematics, distance is often measured using the Euclidean distance formula, which calculates the distance between two points in a plane or in three-dimensional space. The formula is given by:
[tex]d = √((x2 - x1)^2 + (y2 - y1)^2)[/tex]
where d is the distance between the two points, (x1, y1) and (x2, y2).
In physics, distance is often used to describe the separation between two objects or particles. The distance between two objects can affect the strength of gravitational or electromagnetic forces between them. Distance is also an important concept in special relativity, where it is affected by the relative motion of observers and the distortion of spacetime.
a. Greatest possible distance from Austin to san Antonio= Distance from Austin →Houston → san Antonio.
Austin - Houston = 146.43 mi
Houston - San Antonio = 189.34 mi

Simplify and find the undefined numbers

What is simplification?In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.
First, let's simplify the expression:
(4p - 8)/(p³ - 2p²) - (q + 2)/(q³ + 2q²) × (p/2q - p)
= 4(p - 2)/(p²(p - 2)) - (q + 2)/(q²(q + 2)) × p(1/2 - q)
= 4/p - 4/p² - p/2q² + p²/2q
= (8q² - 8pq - p³ + 2p²q)/(2pq²(p - 2))
Now, let's find the undefined numbers, which are the values of p and q that make the denominators equal to zero.
For the first fraction, p³ - 2p² = p²(p - 2) = 0 when p = 0 or p = 2.
For the second fraction, q³ + 2q² = q²(q + 2) = 0 when q = 0 or q = -2.
Therefore, the undefined numbers are p = 0, p = 2, q = 0, and q = -2.

Solve by factoring. ,3x^(2)-27x+60=0 What method of factoring did you use? If you forget how to factor on a multiple choice test, what other methods could you use to solve the quadratic?
The solution of the quadratic equation is x=24/2 and x=-6/2.
To solve the quadratic equation 3x2-27x+60=0, you can use the method of factoring. You can factor this equation by taking out the common factor of 3 from the terms.
That leaves us with x2-9x+20=0, which can be factored into (x-10)(x-2)=0. To solve, you set each factor equal to 0, so x=10 and x=2 are the solutions.
If you forget how to factor on a multiple choice test, you can use other methods such as completing the square or the quadratic formula.
For this equation, completing the square would involve adding and subtracting 92/4 to both sides, which would give us (x-9/2)2=225/4. To solve, you would then take the square root of both sides, resulting in x-9/2=±15/2, or x=24/2 and x=-6/2.

Solve the equation √ y+6=4 and verify the solution. State any restrictions, if they exist.
The restrictions for this equation are that y must be greater than or equal to 0, since the square root of a negative number is not a real number. So, the restrictions for this equation are y ≥ 0.
To solve the equation √y + 6 = 4, we first need to isolate the square root on one side of the equation. We can do this by subtracting 6 from both sides of the equation:
√y = 4 - 6
√y = -2
Now, we need to square both sides of the equation to get rid of the square root:
y = (-2)^2
y = 4
So, the solution to the equation is y = 4. However, we need to verify this solution by plugging it back into the original equation:
√(4) + 6 = 4
2 + 6 = 4
8 = 4
This is not true, so there are no solutions to the equation.
The restrictions for this equation are that y must be greater than or equal to 0, since the square root of a negative number is not a real number. So, the restrictions for this equation are y ≥ 0.

3. Diego works at a carwash and makes a $11 per hour. If he works 9 hours of overtime in a week, how much overtime would he earn?
Consider that overtime is paid at time-and-a-half of his regular rate.
- $158.40
-$130.00
- $150.40
-$148.50
The amount of overtime that Diego would earn would be D. $ 148. 50.
How to find the overtime ?Diego's regular rate is $11 per hour. When he works overtime, he is paid time-and-a-half of his regular rate, which means he earns an additional 50% of his regular rate for each hour of overtime.
So his overtime rate is:
= 11 + ( 11 x 0.5)
= 11 + 5.50
= $16.50 per hour
If Diego works 9 hours of overtime in a week, he would earn:
= 9 x 16.50
= $ 148. 50
In conclusion, if Diego was to work 9 hours of overtime, he would be paid $ 148. 50 for his efforts.

DIC DEEPER Your friend earns 7(1)/(2) dollars each hour. Will she earn enough money to buy a $59 pair of headphones after working 4(3)/(4) hours? If not, how much more money does she need?
No, she will not earn enough money to buy the $59 pair of headphones after working 4(3)/(4) hours. She needs $23.375 more.
To find out how much money she will earn after working 4(3)/(4) hours, we can multiply her hourly wage by the number of hours she works:
7(1)/(2) dollars/hour × 4(3)/(4) hours
Transform the mixed fractions into improper fractions, then multiply.
15/2 dollars/hr x 19/4 hours = 285/8 = 35.625 dollars
So, she will earn $35.625 after working for 4(3)/(4) hours.
To find out how much more money she needs to buy the $59 pair of headphones, we can subtract the amount she earned from the cost of the headphones:
$59 - $35.625 = $23.375
So, she needs $23.375 more to buy the $59 pair of headphones.
