The members of a track team ran laps around their school. They ran a total of 6 3/4, each lap was 7/8 miles long. How many laps did they run?

The use of gunpowder. Specifically military use, this helped fight wars and win wars because they were able to use the gunpowder. (Not 100% sure)

One important invention that was created in the Song dynasty was the invention of paper money.

Before paper money, people in China used metal and stone coins, which were bulky and could get really heavy at times. However, the paper money made it much easier to carry currency over long distances for trading without the large weight that metal coins had.

This invention affects the whole world today, as many countries have adopted the concept of paper money and still use it. Let me know if you need any clarifications or extra info, thanks!

Answer:

Area = 3.897

Step-by-step explanation:

Remark

What you are subtly being told is the side of an equalateral triangle = P/n.

n = the number of sides

n = 3

P = 9

side = 9/3 = 3

The area of an equalateral triangle given 1 side is

Area = sqr(3)  * s^2  /4  

Area = 3.897

1.y varies directly with x

2.substitute the value of x and y in the equation below

y=kx

where k is the constant term

60=20k

k=60\20

k=30

:y=30x.....is the law

To find y when x is 12

You reinstate the law which is y=30x

Then substitutes the value of x to determine y

y=30*12

y=36.

The volume of the given figure is: 126π cubic inches.

A volume is defined as a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of the attached figure will be the sum of the volume of the cylinder and twice the volume of the hemisphere. Therefore, the volume will be:

Volume = Volume of cylinder + 2(Volume of hemisphere)

Volume = (π × R² × H) + 2[²/₃π×R³]

Volume = (π×3²×10) + 2[(2/3)×π×3³]

Volume = 90π +36π

Volume  = 126π in³

Final answer:

The volume of the cylindrical oil drum is 9.426 cubic feet.

Explanation:

The volume of a cylindrical oil drum can be calculated using the formula V = πr²h, where r is the radius of the drum and h is the height. In this case, the diameter of the drum is given as 2 feet, so the radius is 1 foot (since the radius is half the diameter). The height of the drum is given as 3 feet. Therefore, the volume of the oil drum can be calculated as follows:

V = 3.142 × (1 foot)² × 3 feet

Calculating this, we get:

V = 3.142 × 1 foot × 1 foot × 3 feet = 9.426 cubic feet

So, the volume of the oil drum is 9.426 cubic feet.

Answer:

Area = 52 cm2

Step-by-step explanation:

First you have to extend the line. It gave you two rectangles.

To find out the area you have to add this two surfaces.

A1 = 2*10 = 20

A2 = 8*4 = 32

Whole area = A1 + A2 = 20 + 32 = 52 square cm.

You can do this other way around and you get the same answer.

First you have to extend the line. It gave you two rectangles.

To find out the area you have to add this two surfaces.

A1 = 4*10 = 40

A2 = 2*6 = 12

Whole area = A1 + A2 = 40 + 12 = 52 square cm.

The lateral surface area of the prism with dimensions 4 ft, 3 ft, and 1.5 ft is 21 square feet.

To find the lateral surface area of a prism, you need to add the areas of all the lateral faces of the prism.

For a rectangular prism, the lateral surface area can be calculated by finding the perimeter of the base and multiplying it by the height of the prism.

In this case, with dimensions of 4 ft, 3 ft, and 1.5 ft for the rectangular prism:

Calculate the perimeter of the base: Perimeter = 2(length + width)

Perimeter = 2(4 ft + 3 ft) = 2(7 ft) = 14 ft

Then, multiply the perimeter by the height of the prism to get the lateral surface area:

Lateral Surface Area = Perimeter x Height

Lateral Surface Area = 14 ft x 1.5 ft = 21 square feet

The complete question is: Find the lateral surface area of the prism

Answer:

B: (9, 1)

Step-by-step explanation:

The mid point is (5, 3).  Compare the x and y values to point A: (1,5)  

We can see that the 'x' coordinate is 4 units higher than point A, so the x value for point B will be 4 points higher than the x value of the mid point.  

             5 + 4 = 9

We can see that the 'y' coordinate is 2 units less than point A, so the y value for point B will be 2 points less than the y value of the  mid point.  

            3 - 2 = 1

Answer:

B coordinate is  ( 9 ,1).

Step-by-step explanation:

Given  : The midpoint of segment AB is (5, 3). The coordinates of point A are (1, 5).

To find : Find the coordinates of point B.

Solution : We have given

Midpoint of segment AB = (5, 3).

The coordinates of point A =  (1, 5).

Mid point : [tex]\frac{(x_{1}+x_{2}}{2} ,\frac{(y_{1}+y_{2}}{2})[/tex].

On plugging the values.

(5,3) = [tex]+\frac{1+x_{2}}{2} ,\frac{(5+y_{2}}{2})[/tex].

Now on comparing x coordinates

[tex](\frac{(1+x_{2}}{2})[/tex] = 5

On multiplying both number by 2

1 +[tex]x_{2}[/tex] = 10.

On subtracting both sides by 1.

[tex]x_{2}[/tex] = 9

Now on comparing y coordinates

[tex]\frac{(5+y_{2}}{2})[/tex] = 3

On multiplying both number by 2

5 +[tex]y_{2}[/tex] = 6

On subtracting both sides by 5.

[tex]y_{2}[/tex] = 1

Then B coordinate is  ( 9 ,1).

Therefore,  B coordinate is  ( 9 ,1).

Therefore, B coordinate is  ( 9 ,1).

Since the number before the 3 is a 1, the number will stay the same and not be rounded up. If the number was 5 or above, it would be rounded up to a 4.

Check the three attached images.

The first exercise is quite self-explanatory. We have to draw two lines that pass through P and are tangent to the circle.

As for the second, since the circle is tangent to all three side of the triangle, we can conclude that the circle is inscribed in the triangle.

Finally, to draw the common tangent, you have to find the point of intersection between the two circles, and draw a line perpendicular to AB.
