Answer:

B. 18

Step-by-step explanation:

Given:

There are two chord in the circle.

These chords are divided in two segments.

Segments of 1 chord is 21 and 6.

Segments of 2 chord is x and 7.

Now by using Intersecting Chord Theorem which states,

"When two chords intersect each other inside a circle, the products of their segments are equal."

Hence from above theorem we can say that;

x\times7=21\times6\\7x = 126\\x= \frac{126}{7}\\x=18

Hence the Value of x is 18.

Diano4ka-milaya [45]

Answer:

800m

Step-by-step explanation:

this would be solved using Pythagoras theorem

we are to find the base

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

600² + b² = 100²

b² = 10000 - 3600

b² = 6400

take the square root of both sides

b = 800m

Express 4/5 as a decimal using long division
Hoochie [10]

Here, we want to express the given fraction as a decimal by the use of long division

We start by writing the long division sign

We place 5 on the left hand side outside and place 4 inside the long division sign

Now, as we know, 4 cannot divide 5 wholly as it is less than 5

We simply add a 0 at the top of the long division symbol, with a decimal point after it.

Concurrently, we place a zero after 4

Hence we have 40 inside the long division

Then we can divide 40 by 5 to get 8

The 8 now comes after the decimal point

Hence, our answer is 0.8

Pictorally, we can have the representation as follows;

Find the mean, median, mode, and range of the following values: <br> 5, 8, 16, 14, 2, 18, 8.
eduard
Mode is the most.
What number appears the most? 8. 8 appears twice.

Mean is the average.
Add up all the numbers. 5+8+16+14+2+18+8=71
Then divide by how many numbers there are. 71/7=10.1

Median is alway in-between.
If you set up a number line in order of least to greatest, what number is in the middle?
2,5,8,8,14,16,18
we can erase the numbers on each end to find the middle.
2,5,8,8,14,16,18
   5,8,8,14,16
      8,8,14,16
         8,14
Uh oh! There are two numbers in the middle. In this case you find the average of these two numbers. 
8+14= 22
22/2=11

The range is the highest number in your set of data minus the lowest number in your set of data. 
So, 18-2=16 

In conclusion...
Mode:8
Mean:10.1
Median:11
Range:16
