Answer: x≈ 14 . 08

Step-by-step explanation:

Given :

3x - 1 + 9x - 7 + 19 = 180

The first thing is to collect the like term , then we have

3x + 9x -  1 - 7 + 19 = 180

12x + 11 = 180

subtract 11 from both sides

12x = 180 - 11

12x =169

divide through by 12

x = 169/12

x = 14.083333333333

x≈ 14 . 08

Answer: 144 ft squared

Step-by-step explanation:

Let's find the two bases first. They are triangles with a base of 6 and a height of 8. The formula for the area of a triangle is b * h *  1/2 = 6 * 8 * 1/2 = 24. There are two so you would do 24 * 2 which is 48.

Then let's find the area of the other three faces, all of which have a length of 4. One has a width of 8 so you would do 4 * 8 which is 32. Another has a width of 6 so you would do 4 * 6 which is 24. The last one has a width of 10 so you would do 4 * 10 which is 40.

Add up the areas of the two bases and three faces together:

48 + 32 + 24 + 40 = 144 ft squared

Jimmy Dean would make 40 sausages in 8 hours, based on a calculation using his rate of sausage making determined from the 15 sausages he made in 3 hours.

If Jimmy Dean made 15 sausages in 3 hours, we can calculate the rate at which he makes sausages and then use this rate to find out how many he would make in 8 hours. First, find the sausage-making rate by dividing the total sausages made by the total hours worked:

Rate = Total Sausages / Total Hours = 15 sausages / 3 hours = 5 sausages per hour

Next, we multiply this rate by the number of hours we are interested in, which is 8 hours:

Sausages in 8 hours = Rate * 8 hours = 5 sausages/hour * 8 hours = 40 sausages

Therefore, at the same rate, Jimmy Dean would make 40 sausages in 8 hours.

Step-by-step explanation:

In permutations, the order of items matters. The word 'TOY' can be arranged in 6 different ways, calculated using the formula: n!/(n-r)!.

The student is asking a mathematical question related to permutations. Permutations refer to the arrangements of items where the order is important. In this instance, the student is interested in arranging the letters in the word 'TOY'. To calculate the number of ways to arrange these letters, we use the formula: n!/(n-r)!. Here, 'n' is the total number of items and 'r' is the number of items to choose and arrange.

Since 'TOY' has three distinct letters, then 'n' would be 3 and 'r' would also be 3. Applied to the formula, this becomes 3!/(3-3)!. Once you calculate this, you get 6. Therefore, there are 6 possible arrangements of the word 'TOY'.

The coordinates of where diagonals AC and BD intersect at O(2,7).

Step-by-step explanation:

We are given coordinates as A(-1,10) and C(5,4).And we know that the diagonals of parallelogram always bisect each other.

Let us consider O is the intersection point among the diagonals AC and BD. So, the point O bisects the line AC into two equal parts, and also it is the mid-point of AC.

We can find point O using the midpoint formula as,

O (x,y) = ([tex]\frac{(x1+x2)}{2}[/tex] , [tex]\frac{(y1+y2)}{2}[/tex])

         = ([tex]\frac{(-1+5)}{2}[/tex] , [tex]\frac{(10+4)}{2}[/tex])

      = ([tex]\frac{4}{2}[/tex], [tex]\frac{14}{2}[/tex])

     = (2,7)

So Diagonals AC and BD intersects at the point O (2,7).

Final answer:

To determine the cost of streamers and party hats, a system of linear equations is created and solved. The streamers cost $2.50 each, and the party hats cost $1.50 each after solving the system by the elimination method.

Explanation:

To find the cost of streamers and party hats, we need to set up a system of linear equations based on the information provided. Let's denote the price of one roll of streamers as s and the price of one party hat as h.

From the first purchase:

3s + 15h = $30

From the second purchase:

2s + 4h = $11

Now, we'll solve the system using substitution or elimination method. For simplicity, we'll use the elimination method.

First, let's multiply the second equation by 3.75 to match the number of hats in the first equation:

7.5s + 15h = $41.25

Subtract the first equation from this new equation:

7.5s + 15h - (3s + 15h) = $41.25 - $30

4.5s = $11.25

s = $2.50

With the cost of a streamer found, substitute s = $2.50 into the second original equation:

2($2.50) + 4h = $11

$5 + 4h = $11

4h = $6  

h = $1.50

Therefore, the cost of one roll of streamers is $2.50 and the cost of one party hat is $1.50.

Final answer:To determine the cost of streamers and party hats, a system of linear equations is created and solved. The streamers cost $2.50 each, and the party hats cost $1.50 each after solving the system by the elimination method.Explanation:To find the cost of streamers and party hats, we need to set up a system of linear equations based on the information provided.

Answer:

Therefore the price of an foundation drink is $ 3.20(approx).

Step-by-step explanation:

Let the price of one fountain drink be x and one beg of popcorn be y.

The Clayton family bought 4 fountain drinks and 3 begs of popcorn and paid $22.50. The Hanks family bought 5 fountain drinks and 2 begs of popcorn and paid $23.75.

According to the problem,

4x+3y=22.50..............(1)

5x+2y=23.75..............(2)

Equation (1)×5 - Equation (2)×4

20x+15y-(20x+8y)=112.5-91

⇔20x + 15y -20 x-8y=21.5

⇔7y=21.5

⇔y = 3.07

putting the value of y in equation (1)

4x+3×3.07 =22.50

⇔4x=22.50 -9.21

⇔x=3.20

Therefore the price of an foundation drink is $ 3.20(approx).

Step-by-step explanation:

Jason arrives at the factory first

It takes 5 minutes until the other person arrives

Solution:

The time taken is given by formula:

[tex]Time\ taken = \frac{distance}{speed}[/tex]

Jason lives 25 miles away from the factory and drives at 60 miles per hour

Therefore, time taken by Jason is:

[tex]Time\ taken = \frac{25}{60}\ hour[/tex]

Convert to minutes

1 hour = 60 minutes

Therefore,

[tex]Time\ taken = \frac{25}{60} \times 60\ minutes = 25\ minutes[/tex]

Jeremy lives 35 miles away from the factory and drives at 70 miles per hour

Therefore time taken by Jeremy is:

[tex]Time\ taken = \frac{35}{70}\ hour\\\\Time\ taken = \frac{35}{70} \times 60\ minutes\\\\Time\ taken = 30\ minutes[/tex]

They leave their houses at the same time

25 minutes < 30 minutes

Thus Jason arrives first

Jason arrives to the factory in 25 minutes

Jeremy arrives to the factory in 30 minutes

⇒  30 - 25 = 5 minutes

Jeremy arrives after Jason by 5 minutes

It takes 5 minutes until the other person arrives

Cuzzzzz I know this stuff realy well

To solve this, you need to isolate/get x by itself in the equation:

[tex]\frac{9}{4}x-\frac{5}{6}=-\frac{13}{12} x[/tex]      Subtract 9/4x on both sides

[tex]-\frac{5}{6} =-\frac{13}{12} x-\frac{9}{4} x[/tex]   To combine fractions, the denominator has to be the same. They both have a least common denominator (LCD) of 12, so multiply -9/4x by 3/3 to make the denominator 12

[tex]-\frac{5}{6} =-\frac{13}{12}x -(\frac{3}{3})\frac{9}{4}x[/tex]

[tex]-\frac{5}{6} =-\frac{13}{12}x-\frac{27}{12} x[/tex]

[tex]-\frac{5}{6} =-\frac{40}{12} x[/tex]     Multiply the reciprocal of -40/12 to get x by itself, which is -12/40 [basically flipping the fraction or switching the numerator and the denominator]

[tex](-\frac{12}{40})-\frac{5}{6} =(-\frac{12}{40})-\frac{40}{12} x[/tex]  [two negative signs cancel each other out and become positive]

[tex]\frac{60}{240} =x[/tex]      Simplify the fraction

[tex]\frac{1}{4} =x[/tex]

Answer:

a = -7/23.

Step-by-step explanation:

For them to lie on the same line the slope of the line joining the first 2 points must equal the slope of the line joining the second and third points.

so (3 - -5) / (-a+2 - 3) =   (2 - 3) /[(2a + 3) - (-a + 2)]

8 / (-a - 1) = -1 /  (3a + 1)    Cross multiply:

-1(-a - 1) = 8(3a + 1)

a + 1 = 24a + 8

-7 = 23a

a = -7/23.

To find the value of a, we can set the slopes between pairs of points equal to each other and solve for a. The value of a is 14/13.

To determine the value of a such that the points (3, -5), (-a+2,3), and (2a+3, 2) lie on the same line, we can use the slope formula. The slope between two points (x1, y1) and (x2, y2) is given by the formula: m = (y2 - y1) / (x2 - x1). We'll calculate the slopes for the two pairs of points and set them equal to each other to find a.

Let's start by finding the slope between the first two points: (-a+2, 3) and (3, -5).

The slope is: m1 = (3 - (-5)) / (-a+2 - 3), which simplifies to m1 = 8 / (-a-1).

Next, let's find the slope between the second and third points: (2a+3, 2) and (3, -5).

The slope is: m2 = (2 - (-5)) / (2a+3 - 3), which simplifies to m2 = 7 / (2a).

Setting the two slopes equal to each other, we have: m1 = m2. Plugging in the expressions for m1 and m2, we get: 8 / (-a-1) = 7 / (2a). To solve for a, we'll cross-multiply and simplify the equation.

After simplifying, we find that a = 14/13.

Answer:

6360

Step-by-step explanation:

the steps is just 120 times 53 which equals 6360. area= length multiplied by width

The area of a football field that is 120 yards long and 53 yards wide is 98,304,000 square inches.

To calculate the total area of a football field that is 120 yards long and 53 yards wide, you can use the formula for the area of a rectangle, which is length× width.

Step 1: Identify the dimensions of the field. The football field is 120 yards long and 53 yards wide

Step 2: Convert the dimensions into a consistent unit of measure, such as feet. Since there are 3 feet in a yard, multiply each dimension by 3.

Length in feet: 120 yards× 3 feet/yard = 360 feet

Width in feet: 53 yards × 3 feet/yard = 159 feet

Step 3: Calculate the area in feet. Area = Length × Width.

Area = 360 feet × 159 feet = 57,240 square feet

Step 4: To get the area in square inches, recognize that there are 12 inches in a foot, so the area in square inch\

es is:

Area in square inches = 57,240 ft²× (12 inches/foot)² = 98,304,000 square inches.

This calculation shows that the total area of the football field is approximately 98,304,000 square inches.
