sally draws a triangle with one side 6 inches long and another side 8 inches long. which is NOT a possible length for the third side ? A) 4 in B)10 in C) 12 in D) 14 in

Answers

Answer 1
Final answer:

When constructing a triangle with given side lengths, the possible range for the third side can be determined by adding and subtracting the lengths of the existing sides. Side lengths of 4, 10, and 14 inches are not possible choices for the third side length.

Explanation:

The third side of a triangle must be less than the sum but greater than the difference of the other two sides. Given sides of 6 inches and 8 inches:

6 + 8 = 14 inches8 - 6 = 2 inches

Therefore, the lengths of the sides 4, 10, and 14 inches are not possible.

s?

Answers

Final answer:

By calculating and comparing the price per pound of meat for each shopper, it is clear that they paid different prices per pound ($3.29 and $4.19), indicating they did not buy the same kind of meat.

Explanation:

To determine if both shoppers bought the same kind of meat, we need to calculate the price per pound that each shopper paid and compare the results. The first shopper bought 3 pounds for $9.87. To find the price per pound, we divide $9.87 by 3 pounds, which gives us $3.29 per pound.

The second shopper bought 4 pounds for $16.76. Similarly, we divide $16.76 by 4 pounds to get $4.19 per pound. Since the price per pound for each shopper is different, we can deduce that they did not buy the same kind of meat.

Answer:

Shown in the picture

Step-by-step explanation:

A:

Set the value of x to "5" and "30" to find the corresponding values of y (i.e. the altitudes of the plane at 5 or 30 minutes after beginning descent).

B:

Use the the same method to determine the set of coordinates (/ordered pairs) at each of the values for x given in part B of the question.

C:

The initial value is simply the starting value of y, or in other words, the altitude at which the plane begins to descend in this context;

So it will be 0 mins after the beginning of descent of the plane, i.e. when x = 0, therefore the answer is (0, 28000) as an ordered pair or simply 28000 ft.

D:

Rate of change is a fancy or more technical way of referring to the gradient of a function;

In this case of the context of a plane descending, it refers to the change in altitude over time;

This can be calculated using any two ordered pairs (or coordinates as I call them) using the formula of the difference in the y values divided by the difference in the x values.

What are the coordinates of the image of vertex R after a reflection across the y-axis? (–4, 3) (4, –3) (–3, –4) (3, 4)

Answers

(–4, 3) (4, –3) (–3, –4) (3, 4)

this is a rather simple yet complex concept the easiest way to solve these is to do the exact opposite.

so in this instance it is refrcted across the y-axiss so we swap ONLY the x value NOT the Y ie (-4,3) would switch to (4,3)

The coordinates of the image of vertex R after a reflection across the y-axis is (3, 4).

What is reflection?

A reflection is an involution: when applied twice in succession, every point returns to its original location, and every geometrical object is restored to its original state.

Given is a point R = (-3, 4) we need to find the coordinates of the point R after it being reflected over y-axis,

So, we know that,

When dealing with reflection of a line or shape or a figure in the coordinate plane, especially if it is reflected across the y-axis, you just have to give the opposite of the given (original) x- coordinate in order to give a symmetric figure.

The rule of reflection over y-axis is =

(x, y) = (-x, y)

So,

R = (-3, 4), after it being reflected over y-axis =

R' = (3, 4)

Hence the coordinates of the image of vertex R after a reflection across the y-axis is (3, 4).

#LearnwithBrainly

Final answer:

To solve the given system of linear equations, we use the elimination method to find the intersection point (14, 109), which is where the two lines represented by the equations meet.

Explanation:

To solve the system of equations:

y = 5x + 39

y = 3.5x + 60

We can use the method of substitution or elimination. In this case, elimination is the straight-forward choice. Since both equations are already solved for y, set them equal to each other and solve for x:

5x + 39 = 3.5x + 60

Now, subtract 3.5x from both sides:

1.5x + 39 = 60

Subtract 39 from both sides:

1.5x = 21

Divide both sides by 1.5:

x = 14

Now, plug the value of x into one of the original equations to solve for y:

y = 5(14) + 39

y = 70 + 39

y = 109

The solution to the system is (14, 109). This represents the point where the two lines intersect on a graph.

A building is 3 ft from an 8​-ft fence that surrounds the property. A worker wants to wash a window in the building 13 ft from the ground. He plans to place a ladder over the fence so it rests against the building.​ (See the​ figure.) He decides he should place the ladder 8 ft from the fence for stability. To the nearest tenth of a​ foot, how long a ladder will he​ need?

Answers

Answer:

Length of the ladder used by worker = 17 feet

Step-by-step explanation:

Given:

Height of the window from the ground = 13 ft

Distance of fence from the building = 3 ft

Distance of ladder from the building = (3+8) = 11 ft

We have to find the length of the ladder.

Let the length of the ladder be 'x'

From the diagram we can also say that 'x' is the hypotenuse of the right angled triangle.

Using Pythagoras formula:

⇒ [tex]hypotenuse\ 'x' =\sqrt{(perpendicular)^2+(base)^2}[/tex]

Here base length = 11 ft

Perpendicular = 13 ft

Plugging the values:

⇒ [tex]x=\sqrt{(13)^2+(11)^2}[/tex]

⇒  [tex]x=\sqrt{(169+121)}[/tex]

⇒ [tex]x= \sqrt{290}[/tex]

⇒ [tex]x=17.02[/tex] feet

The length of the ladder = 17 feet to its nearest tenth.

The worker will need a ladder that is approximately 8.5 feet long. This calculation is based on the Pythagorean theorem, considering the ladder's placement 8 feet from the fence and the need to reach a window 13 feet above the ground.

To find the length of the ladder the worker needs, we can use the Pythagorean theorem, as the ladder, the distance from the building, and the distance from the fence form a right triangle.

Let:

L be the length of the ladder.

D be the distance from the building to where the ladder rests (8 ft).

F be the distance from the fence to where the ladder rests (3 ft).

According to the Pythagorean theorem, we have:

[tex]L^2 = D^2 + F^2[/tex]

Substitute the known values:

[tex]L^2 = 8^2 + 3^2[/tex]

[tex]L^2 = 64 + 9[/tex]

[tex]L^2 = 73[/tex]

Now, take the square root of both sides:

L ≈ √73 ≈ 8.54 ft (rounded to the nearest tenth)

So, the worker will need a ladder that is approximately 8.5 feet long to safely reach the window 13 feet above the ground when placed 8 feet from the fence for stability.

<=> -2p + 3p > -6 + 9

<=> p > 3

To solve the inequality 3(p-3) - 5p > -3p - 6:

Simplify and combine like terms to get p > 3 as the solution.

An inequality is a mathematical statement that uses the inequality symbol to indicate the relationship between two expressions. Both sides of an inequality sign have different expressions.

The given expression is:

3(p-3) – 5p>-3p- 6

-2p - 9 > -3p - 6

Move all the terms containing p to one side by adding 3p to both sides: -2p + 3p - 9 > -6

Simplify:

p - 9 > -6

Move the constant term to the other side by adding 9 to both sides:

p - 9 + 9 > -6 + 9

Simplify: p > 3

Distance in meters D = 167.75 meters

Step-by-step explanation:

Distance covered in 5 seconds is given by:

Distance, D = Speed (S) X Time (T)

Where,

Distance = ?

Speed = 75mph

Time = 5s

Since we are calculating distance in meters, we have to convert 75miles per hour to meters per second

75mph = 75miles/1hr X 1km/0.621miles X 1000m/1km X 1hr/60mins X 1min/60s

            = (75X1000) / (0.621X60X60) meter per second

            = 75000/2235.6 meter per second

            = 33.55 meter per second

∴ Distance D = 33.55 meter per second X 5 seconds

What is the product? [4 2] x [-2 5 7 -1]

Answers

Answer:

The answer is [6 18}

Step-by-step explanation:

I just took the test :)

The product of the matrices [4 2] and [-2 5 7 -1] is a 1x4 matrix. The resulting matrix is [-8 -4 20 10].

 

In order to find the product of two matrices, we need to ensure that the number of columns in the first matrix matches the number of rows in the second matrix. The first matrix, [4 2], has 1 row and 2 columns (1x2), while the second matrix, [-2 5 7 -1], has 2 rows and 4 columns (2x4). Since the number of columns in the first matrix matches the number of rows in the second matrix, we can proceed with matrix multiplication.

To compute the product, we perform the following steps:

Step 1: Take the first row of the first matrix and multiply each element by the corresponding element in the first column of the second matrix.  

- First element: 4 * (-2) = -8  

- Second element: 2 * (-2) = -4

Step 2: Take the first row of the first matrix and multiply each element by the corresponding element in the second column of the second matrix.  

- Third element: 4 * 5 = 20  

- Fourth element: 2 * 5 = 10

Step 3: Now, we have the elements for the first row of the resulting matrix: [-8 -4 20 10].

Step 4: Repeat the above steps for the second row of the first matrix.

Step 5: Combine the results to form the final product matrix: [-8 -4 20 10].

So, the product of the matrices [4 2] and [-2 5 7 -1] is the 1x4 matrix

[-8 -4 20 10].
