Insert parentheses in the expression 6 + 10 x 2 so that the expression equals 32
Final answer:
By inserting parentheses to create the expression (6 + 10) x 2, we change the order of operations and get the desired result, which is 32.
Explanation:
The question involves inserting parentheses in the expression 6 + 10 x 2 so that the result of the expression equals 32. According to the order of operations, we typically perform multiplication before addition, so if we compute the expression as it stands, we would get 6 + (10 x 2) = 6 + 20 = 26, which is not the result we want. To achieve the desired result, we need to adjust this order. By adding parentheses, we can change the order in which the operations are performed. Thus, the correct placement of parentheses would be (6 + 10) x 2, which gives us (16) x 2 = 32.

X3-5X2-24X factor this
Answer:
x(x - 8)(x + 3)
Step-by-step explanation:
take out a common factor of x
= x(x² - 5x - 24)
to factor the quadratic consider the factors of - 24 which sum to - 5
These are - 8 and + 3, thus
= x(x - 8)(x + 3) ← in factored form
Final answer:
To factor X³-5X²-24X, we first factor out the greatest common factor, X, and then factor the resulting quadratic equation, resulting in the factored form X(X-8)(X+3).
Explanation:
The polynomial X³−5X²−24X can be factored by first taking out the common factor of X, which gives us X(X²−5X−24). Next, we need to factor the quadratic equation X²−5X−24. To do this, we look for two numbers that multiply to −24 and add up to −5, which are −8 and 3. Therefore, the factored form is X(X−8)(X+3).
bottle a contains 4 ounces of water, which is 25% of the amount of water in bottle b. How much water is in bottle b?
Final answer:
By setting up a proportion based on the fact that 4 ounces represents 25% of the amount in bottle B, we calculated that bottle B must contain 16 ounces of water.
Explanation:
The question asks us to determine how much water is in bottle B given that bottle A contains 4 ounces of water, which is 25% of the amount of water in bottle B. This means bottle A has one-fourth the amount of water that is in bottle B.
To find out how much water is in bottle B, we can set up a simple proportion: if 4 ounces is 25%, then 100% (which is the full amount in bottle B) would be four times as much. Therefore, we multiply 4 ounces by 4.
4 ounces × 4 = 16 ounces
So, bottle B contains 16 ounces of water.

y=-1/3x +1 find a perpendicular line from a point on (3,4)
Answer:
y = 3x - 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - [tex]\frac{1}{3}[/tex] x + 1 is in this form
with slope m = - [tex]\frac{1}{3}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-1/3}[/tex] = 3
y = 3x + c ← is the partial equation
to find c substitute (3, 4) into the partial equation
4 = 9 + c ⇒ c = 4 - 9 = - 5
y = 3x - 5 ← equation of perpendicular line

A residual plot showing a quadratic pattern suggests the current linear regression model is inappropriate and a non-linear model might be required. Answer D is correct: the residual plot indicates the regression equation is not a good fit for the data.
When a residual plot exhibits a pattern, such as a quadratic function, this indicates that the regression equation used to fit the data may not be appropriate; specifically, it suggests that a linear model does not properly capture the relationship between the variables. Instead, the underlying relationship may be better modeled with a non-linear equation, such as a quadratic function.
The correct answer to the student's question is D) That the regression equation is not a good fit for the data.
A good residual plot will have residuals scattered randomly around the horizontal axis, which means that the regression model adequately captures the pattern in the data.

write an inequality that represents 10 less than four times a number is more than 1000
Answer:
Step-by-step explanation:
Unknown number be 'x'
4x-10>1000
An inequality representing '10 less than four times a number is more than 1000' is written as 4x - 10 > 1000. We rearrange the inequality to solve for x, resulting in x > 252.5, indicating that four times any number greater than 252.5, minus 10, will be more than 1000.
To write an inequality that represents "10 less than four times a number is more than 1000," we need to use an inequality symbol to show the relationship between the expressions involved. The number we are considering can be represented by a variable, typically denoted as x. So, four times a number would be written as 4x. Following this, 10 less than four times a number is expressed as 4x - 10. Now, stating that this quantity is more than 1000, we use the > sign, leading to the inequality 4x - 10 > 1000. To solve this inequality, we can rearrange the terms to isolate x, resulting in the following steps:
Add 10 to both sides: 4x - 10 + 10 > 1000 + 10Simplify the inequality: 4x > 1010Divide by 4 to solve for x: x > 1010/4Thus, the solution to the inequality is x > 252.5This inequality represents that any number greater than 252.5, when multiplied by four and reduced by 10, will result in a value more than 1000.

Answer:
D: (-infinity, infinity) R: (-infinity, infinity)
Step-by-step explanation:
The absolute value of x - 3 is x+ 3.
y = x + 3 + 1
y = x + 4
Your y intercept is your c value. Your c value is 4.
4 is your y intercept.
Place a point on 4. This is your starting point. Rise over run is 1/1
To find the positive points, go up one from the y intercept and over one, repeating the process until you reach the edge of the graph.
To find the negative points, do the opposite. Go down one and to the left, but still repeat the process until you reach the end of the graph.
Linear equations are always ended with arrows on both sides, meaning that the line continues forever, or infinitely.
To find domain, look at the x values.
Because the lines go on infinitely, you know that your domain is (-infinity, infinity).
To find your range, look at your y values.
Because the lines go on infinitely, you know that your range is also (-infinity, infinity).
Make sure to use the symbol for infinity instead of the words. In case you do not know what the infinity symbol is, it simply looks like an 8 that is rotated 90 degrees.

Chris works at Higgins’ Automart and is selling a new Shelby Mustang for $59,000. If he earns a commission of 3%, how much money does he earn? Write a proportion and show all steps of your work.
The answer I came up with is 177.
Answer:
$1770
Step-by-step explanation:
Remember that percent means "out of 100". 3% as a ratio is 3:100 or 3/100.
59,000 is the total amount, the whole, so it corresponds to 100%.
The problem is asking:
59,000 is to 100 as what is to 3?
59,000/100 = x/3
Cross multiply:
100x = 59,000 * 3
100x = 177,000
x = 1770
The commission is $1770.

Gas costs $2.09 and you figure you will use 30 gallons on your trip with your two friends. You will stay 4 nights at a hotel (one room) for $98 a night, and spend $25 each per day on food for 5 days. What is the total cost of your trip?
Final answer:
The total trip cost, including gas, hotel, and food for three people, is $829.70, calculated by multiplying the quantities by their respective unit prices and summing up all costs.
Explanation:
Calculating the Total Trip Cost
To calculate the total cost of the trip, we need to consider the cost of gas, hotel, and food. For gas, the cost is $2.09 per gallon, and the consumption is 30 gallons. The hotel cost is $98 per night for 4 nights. Each person's food cost is $25 per day for 5 days.
Here is the detailed calculation:
Therefore, the total cost of the trip is $829.70.
The total cost of the trip is $705.70.the total cost of the trip amounts to $705.70. This includes various expenses such as gas for the trip calculated at $62.70, hotel expenses totaling $392 for the four-night stay, and food expenses adding up to $375 for three people over five days.
Explanation:To calculate the total cost, start with the gas cost: 30 gallons * $2.09/gallon = $62.70. Next, calculate the hotel expenses: 4 nights * $98/night = $392. Then, calculate the food expenses: 3 people * $25/day * 5 days = $375. Add all these expenses together: $62.70 (gas) + $392 (hotel) + $375 (food) = $829.70.
However, to account for the cost shared among friends, divide the total by 3: $829.70 / 3 = $276.57 per person. Finally, multiply the individual cost by 3 people to find the total cost: $276.57/person * 3 people = $829.70. The final total cost of the trip, considering shared expenses, is $705.70. This includes gas, hotel accommodation, and food for three individuals across the entire trip duration.
In summary, the total cost of the trip amounts to $705.70. This includes various expenses such as gas for the trip calculated at $62.70, hotel expenses totaling $392 for the four-night stay, and food expenses adding up to $375 for three people over five days.
The calculation incorporates sharing costs among the three friends, dividing the overall expenses equally. Each individual's share amounts to $276.57, resulting in a final total cost of $705.70 for the entire trip. This comprehensive calculation considers all major expenses incurred during the trip and divides the shared costs among the friends, arriving at the total trip expenditure.

An artist is creating a large butterfly sculpture outside a museum. There is a circular dot on each wing made out of metal ring. The distance around each dot is 24π inches. The artist plans to fill the inside of each dot with blue colored glasses. What is the area of the blue glass will be needed to fill each butterfly dot?
The area of the blue glass needed to fill each dot is 144π square inches.
Explanation:To find the area of the blue glass needed to fill each dot, we need to first determine the radius of the dot. The distance around each dot is given as 24π inches, which means the circumference of the dot is 24π inches.
Using the formula for circumference, 2πr = 24π, we can solve for the radius r, which is 12 inches. The area of the blue glass needed to fill each dot is then the area of a circle with radius 12 inches, which is given by the formula A = πr^2.
Substituting the value for r, we get A = π(12)^2 = 144π square inches.

Use an equation to find the value of k so that the line that passes through (-4, k)(−4, k) and (6, −7) has a slope of m= -1/5.
Answer:
The value of k is -5.
Step-by-step explanation:
To find the value of k, start by using the known information we have in the equation for slope. The equation is below.
m(slope) = (y2 - y1)/(x2 - x1)
In this equation, the first ordered pair would be (x1, y1) and the second would be (x2 , y2). So we put the values in for these variables and we get.
-1/5 = (-7 - k)/(6 + 4)
-1/5 = (-7 - k)/10
Now we can use cross multiplication to solve for k.
-1/5 = (-7 - k)/10
-1*10 = 5(-7 - k)
-10 = -35 - 5k
25 = -5k
-5 = k
Answer:
k=-5
Step-by-step explanation:
To find the value of k, start by using the known information we have in the equation for slope. The equation is below.
m(slope) = (y2 - y1)/(x2 - x1)
In this equation, the first ordered pair would be (x1, y1) and the second would be (x2 , y2). So we put the values in for these variables and we get.
-1/5 = (-7 - k)/(6 + 4)
-1/5 = (-7 - k)/10
-1/5 = (-7 - k)/10
-1*10 = 5(-7 - k)
-10 = -35 - 5k
25 = -5k
-5 = k
Simplify: -|-10| + 3-39/4

two runners start 30kilometer apart and run toward each other. they meet after 3hours. One Runner runs 2 kilometers per hour faster than the other runner. What rate do they run
Let the slower runners speed be X kilometers per hour.
Then the faster runners speed would be X+2 kilometers per hour.
The formula for distance is Speed times time.
The distance is given as 30 kilometers and time is given as 3 hours.
Since there are two runners you need to add the both of them together.
The equation becomes 30 = 3x + 3(x+2)
Now solve for x:
30 = 3x + 3(x+2)
Simplify:
30 = 3x + 3x +6
30 = 6x + 6
Subtract 6 from each side:
24 = 6x
Divide both sides by 6:
x = 24/6
x = 4
The slower runner ran at 4 kilometers per hour.
The faster runner ran at 4+2 = 6 kilometers per hour.
find the slope of line through on the points (-8,5) and (-23,2)
Use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (2 - 5)/(-23 - (-8))
m = (2 - 5)/(-23 + 8)
m = (-3)/(-15)
m = 1/5
m = 0.2
