Question: Find the circumference of the circle to the nearest hundredth

d = 11cm

Answer:

34.54 cm

Step-by-step explanation:

Applying,

P = πd...................... Equation 1

Where P = Circumference of perimeter of the circle, d = diameter of the circle, π = pie

From the question

Given: d = 11 cm

Constant: π = 3.14

Substitute these values into equation 1

P = (3.14×11)

P = 34.54 cm

Answer:

Mean: 12.6

Median: 12

Mode: None

Step-by-step explanation:

To find the mode, add everything up.

12 + 9 + 17 +15 + 10 = 63. Then, divide by five.

63 ÷ 5 = 12.6

To find the median, put the numbers from least to greatest. Then, highlight the one in the middle.

9, 10, 12, 15, 17

To find the mode, look for the number that appears the most. Because each number appears once. So, put "none" in the box.

Have a wonderful day!

Answer:

Step-by-step explanation:

When we transpose - 4x to the LHS then it becomes positive i.e +4x

Now we transpose 28 to the RHS then it becomes negative i.e - 28

So the first step you have to is,

4x = - 12 - 28

Answer:

3220 cm²

Step-by-step explanation:

Lets find the area of the two triangles

I am making a modification:

Both of the triangles are the same, so I wont divide by 2 using the area of triangle formula 1/2(b * h) because we end up multiply by 2

Area of triangles = 15 cm x 28 cm = 420 cm²

Area of front facing parallelogram = 24 cm x 4(10)cm = 100(10)cm = 1000 cm²

Area of back facing parallelogram = 17 cm x 40 cm = 680 cm²

Area of bottom parallelogram = 40 cm x 28 cm = 1120 cm²

Total Surface area = 420 cm² + 1000 cm² + 680 cm² + 1120 cm² = 1100 cm² + 2120 cm² = 3220 cm²

Answer:

b*h/2   120*90/2 10800/2=5400

Step-by-step explanation:

The area of the red triangle with sides A= 90 B=120 and C=150 would be equal to 5400.

The area of the triangle is defined as the product of half the base and the height of the triangle.

The area of the triangle = 1/2 x b x h

It is given that the length of the sides are as A= 90 B=120 C=150.

So, The area of the triangle = 1/2 x b x h

= b x h/2  

= 120 x 90/2

= 10800/2

= 5400

2/21 * (6x-7)

Step-by-step explanation:

1/21 * (3*4x - 14)

1/21* (12x-14)

1/21* 2(6x-7)

2*1/21 * (6x-7)

2/21* (6x-7)

Step-by-step explanation:

|3x - 4| = 6

3x-4 = 6 or 3x-4 = -6

3x=6+4 3x=-6+4

3x=10 3x = -2

x= 10/3 x = -2/3

so, x1= 10/3 or x2 = -2/3

Answer:

9.5 seconds

Step-by-step explanation:

0-4 seconds => 20 meters

4-9.5 seconds => 55 meters

total = 75 meters

A horse run a distance of 75 metres in 9.5 seconds.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time.

Here, From the graph,

when, t = 4 sec.

    distance = 4 X 10 X 1/2

                    = 20 meters

Now, 75 - 20 = 55 meters

So, 55/10 = 5.5 seconds

Total time = 5.5 + 4

                 = 9.5 sec.

A horse run a distance of 75 metres in 9.5 seconds.

Thus, A horse run a distance of 75 metres in 9.5 seconds.
