A= 1/2 base*height

Step-by-step explanation:

: )

The correct equation for calculating the area of a triangle is D = 1/2 base · height.

The equation for calculating the area of a triangle is D = 1/2 base · height. This formula represents the most commonly used method for finding the area of a triangle.

To use this formula, you multiply the base of the triangle by its corresponding height, and then divide the result by 2.

This is because the area of a triangle is equal to half the product of its base and height.

By dividing by 2, we account for the fact that a triangle is essentially half of a parallelogram.

Therefore, the correct equation for calculating the area of a triangle is D = 1/2 base · height.

Answer:

The graphs of speed related to time for a brick being dropped from the top of a building and a ball that was rolled down a hill then came to rest would be the same in the following way:

- At the initial moment, before either object starts to move, the speed of both objects would be zero.

The graphs would differ in the following ways:

- The shape of the graph for the brick would be a straight line, with a constant speed of acceleration due to gravity until it hits the ground.

- The shape of the graph for the ball would be a curve that starts at zero speed, increases as the ball gains speed rolling downhill, and then decreases to rest as the ball comes to a stop.

- The time taken for each object to reach its final speed would be different, since the brick has a shorter distance to fall than the ball has to roll.

The volume of the composite figure is 6,330.24 in^3

We know that the volume of half a sphere of radius R is:

V = (2/3)*pi*R^3

Here we know that pi = 3.14 and R = 12 inches, then the volume is:

V = (2/3)*3.14*(12 in)^3 = 3,617.28 in^3

And the volume of a cone of height H and radius R is:

v = (1/3)*pi*R^2*H

So here the volume is:

v = (1/3)*3.14*(12in)^2*18in = 2,712.96 in^3

Then the total volume is:

3,617.28 in^3 +  2,712.96 in^3 = 6,330.24 in^3

Answer:

The system of linear equations has no solution.

Step-by-step explanation:

We can solve the system of linear equations using substitution or elimination method.

Here's how you can solve it using substitution:

Solve one equation for either x or y.

Substitute the expression you found in step 1 into the other equation.

Solve for the remaining variable.

Use the values you found in steps 3 to find the other variable.

Starting with the first equation:

3y = 6 + x

Solving for x:

x = 3y - 6

Next, we substitute this expression into the second equation:

3x - 9y = 9

Plugging in x = 3y - 6:

3(3y - 6) - 9y = 9

Expanding the left-hand side:

9y - 18 - 9y = 9

Combining like terms:

0y - 18 = 9

Adding 18 to both sides:

0y = 27

Since y cannot equal 0, we have a contradiction and the system has no solution.

So, the system of linear equations has no solution.

Surface area in a ladder

There are 6 surface steps, 3 horizontal , 3 vertical

Area of 1 horizontal rectangle is : 25x 90 = 2250

then Area of 3 is 3x 2250= 6750

Area of 1 vertical rectangle is : 16 x 90 = 1440

Area of 3 verticals = 3x 1440 = 4320

NOW find area of

Floor,. 2 vertical walls,. 1 back wall

Floor area = 90 x (25+25+25) = 90x 75 = 6750

Vertical walls = 2 x 25x ( (16+16+16)+(16+16)+16) = 2x 25 x 96 = 4800

Back wall = 90x (16+16+16) = 4320

SO finally add all these 5 results

6750 + 4320 + 6750 + 4800 + 4320 =

Resulting in finally = 26,940

Given the equations a × b = 5742 × 6368, a × c = 5748 × 6362, and c × b = 5738 × 6372, we need to determine the relationship between the three variables a, b, and c.

By comparing the given equations, we notice that the numbers on the right-hand side of each equation are very close to each other, differing only by small amounts. This suggests that a, b, and c are approximately equal.Since a × b, a × c, and c × b involve the same numbers with slight variations, we can conclude that a, b, and c are all very close in value.

Therefore, the inequality we can infer from this information is a ≈ b ≈ c, indicating that a, b, and c are approximately equal.

In simple terms, based on the given equations, it suggests that the values of a, b, and c are very similar or approximately equal to each other.

Step-by-step explanation:

as the graphic shows, we are dealing with a special rhombus : a square.

this is proven by the fact that the angle on one side of the diagonal at the corner is 45°. so, the other side must be 45° too, and so we have 90° angles at the corners.

what is not clear to me is : what is 6 cm long ? a half-diameter, or the whole diameter ?

I assume the half-diameter.

what the graphic is trying to suggest is that we have 4 little right-angled triangles that are also isoceles triangles (their legs are equally long).

every leg is 6 cm long (based on my assumption above).

because they are right-angled, the area of each of these little triangles is leg×leg/2

6×6/2 = 18 cm²

we have 4 triangles, so the total area is

4×18 = 72 cm²

if 6 cm stands for the whole diagonal after all, then the only change is the length of the legs, which would be then 6/2 = 3 cm.

then we would have

3×3/2 = 4.5 cm² for a single triangle

and

4×4.5 = 18 cm² for the whole area.

Step-by-step explanation:

The package that is the best buy is the 15-ounce package that cost $4.65.

7​-ounce noodles package costs ​$2.24.

15​-ounce noodles package costs ​$4.65.

18​-ounce noodles package costs ​$5.94.

Therefore, let's calculate the rate for each to find the best buy.

For 7​-ounce noodles package costs ​$2.24.

rate = 2.24 / 7

rate = $0.32 per ounce

For 15​-ounce noodles package costs ​$4.65.

rate = 4.65 / 15

rate = $0.31 per ounce

For 18​-ounce noodles package costs ​$5.94.

rate = 5.94 / 18

rate = $0.33 per ounce

Therefore, the package that is the best buy is the 15-ounce package that cost $4.65.

\(y +2 =-6(x - 1)\)

Step-by-step explanation:

Given

\((x_1,y_1) = (1,-2)\)

\(m=-6\)

Required

Determine the point slope equation

This can be determined using the following formula:

\(y - y_1 =m(x - x_1)\)

Where:

\((x_1,y_1) = (1,-2)\)

\(m=-6\)

So, we have:

\(y - (-2) =-6(x - 1)\)

This gives:

\(y +2 =-6(x - 1)\)

Hence, the point slope form is \(y +2 =-6(x - 1)\)
