Last question I promise.

Given:

Diagram of a circle and its two secant from an exterior point.

To find:

The value of x.

Solution:

We know that, If two secant are on a circle from an exterior point, then the products of measure of secants and measure of external segments of secants are equal.

Using the above property, we get

[tex](x+7)x=(2+2)2[/tex]

[tex]x^2+7x=(4)2[/tex]

[tex]x^2+7x=8[/tex]

[tex]x^2+7x-8=0[/tex]

Splitting the middle term, we get

[tex]x^2+8x-x-8=0[/tex]

[tex]x(x+8)-1(x+8)=0[/tex]

[tex](x+8)(x-1)=0[/tex]

Using zero product property, we get

[tex](x+8)=0[/tex] and [tex](x-1)=0[/tex]

[tex]x=-8[/tex] and [tex]x=1[/tex]

Side cannot be negative.

Therefore, the only possible value of x is 1.

Step-by-step explanation:

1) 6/11 ÷ 2/5 = 15/11 or 1.3636... or 1 4/11 as a mixed number.

2) 8,299 ÷ 43 = 193

3) 28.40 x 0.87 = 24.708

4) 3,948.99 + 489.08 = 4438.07

5) What is 40% of 90 = 36

6) Greg kicked the soccer ball 75 feet. How many yards did he kick the ball? 25 yards

7) Write an expression that represents 72 divided by n plus 4? 72/n+4

8) How many feet are in 3 miles? 15840

hey this is all I can do and see but I hope this helps. p.s. I really need brainliest :)

Answer:

The number of times the  variability in the heights of the seventh graders is the variability in the heights of the sixth graders is:

                         3.0

In order to find the variability between the two sets we divide the mean absolute deviation of the first set of data by the mean absolute deviation of the second set of the data.

The MAD of first set of data is: 1.2

and MAD of second set of data is: 0.4

Hence, let n be the number of times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders.

Answer:

1)88 2)44.5

Step-by-step explanation:

i'm not sure about 3 and 4

Answer:

1.) 88cm²

2.) 44.5cm²

3.) 141.37cm²

4.) 44cm²

Step-by-step explanation:

Alrighty, we're just going to do an abridged version, but if you need me to explain it more, I can:

1.) 6 x 8 ÷ 2 = 24

8 x 8 = 64

64 + 24 = 88

1.) 88cm²

2.) 2 + 2 + 3 = 7

7 x 5 ÷ 2 = 17.5

9 x 3 = 27

27 + 17.5 = 44.5

2.) 44.5cm²

3.) 3.14 x 3² = 28.27

3.14 x 6² = 113.1

28.27 + 113.1 = 141.37

3.) 141.37cm²

4.) 3.14 x 4² ÷ 2 = 25.135

4 x 2 = 8

8 x 9 ÷ 2 = 36

8 + 36 = 44

4.) 44cm²

if any of these are wrong, let me know

hope this helps:)

The experimental probabilities of each outcome are given as follows:

The theoretical probability of each outcome is given as follows:

1/5.

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes.

For the experimental probability, we consider the 30 trials in the table.

For the theoretical probability, we consider that each of the outcomes is equally as likely, hence the probability is given as follows:

p = 1/5.

Answer:

5625 feet

I hope it's helps you

Answer:

5625 feets

Step-by-step explanation:

Rate(feet/seconds) = height(feets)/time(seconds)

175 = x/25

x = 4375

After the skydiver opens his parachute the height reduces

Initial height – reduced height

10000 – 4375

= 5625 feets

Answer:

<1 = 50

<2 = 40

<3 = 90

<4 = 90

<5 = 40

<6 = 50

<7 = 130

Step-by-step explanation:

<5 + <6 = 90

40 + <6 = 90

<6 = 50

<5 = <2 because of vertical angles

<2 = 40

<6 = <1 because of vertical angles

<1 = 50

<7 = <4 + <5

<7 = 90 + 40

<7 = 130

Answer:

Solution given:

<4=90°[vertically opposite angle]

<2=<5=40°[vertically opposite angle]

<3=90°[right angle]

again

<1+<2=90°[right angle]

<1=90°-40°=50°

<1=50°

again

<5=40°[given]

<6=<1=50°[vertically opposite angle]

<6=50°

again

<7=<4+<5=90°+40°=130°
