Answer:

x = 46

Step-by-step explanation:

Given 2 secants from an external point to the circle, then

The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is

2(2 + x) = 6(6 + 10)

2(2 + x) = 6 × 16 = 96 ( divide both sides by 2 )

2 + x = 48 ( subtract 2 from both sides )

x = 46

Answer:

A = 78.5 ft

Step-by-step explanation:

D=10ft

R=D/2

R=5ft

A=πr²

A=π5²

A=π25

A=78.53982

A=78.5ft

Answer:

8,5 feet

Step-by-step explanation:

The equation of the form

x² + y² = (r)²

Is the equation of the circumference

We have for the pool:

x²  +  y²  = 2500      ⇒  x²  +  y²  = (50)²

And for the outside edge of the footpath

x²  +  y²  = 3422,25  ⇒  x² + y²  = (58,5)²

So we obtain the radius of each circumference

For the outside edge of the pool  r₁  = 50 feet

For the outside edge of the footpath r₂ = 58,5  feet

Then the width of the footpath is  58,5  - 50  =  8,5 feet

Given:

Number of winter coats = 2

Number of hats = 4

Number of scarves = 3

To find:

The total number of different outfit combinations.

Solution:

Number of winter coats is 2. So, the number of ways to select a winter coat from 2 coats is 2.

Number of hats is 4. So, the number of ways to select a hat from 4 hats is 4.

Number of scarves is 3. So, the number of ways to select a scarf from 3 scarves is 3.

So, the total number of ways is:

[tex]2\times 4\times 3=24[/tex]

Therefore, Helen have 24 different outfit combinations.

Answer:

Geometric Sequence.

Step-by-step explanation:

We are told that the square is split into 4 similar squares. One of the new squares is now split into fourths again and this same sequence is repeated over again.

This means that there is a common ratio which is ¼.

Since there is a common ratio and not common difference, this sequence is said to be a geometric sequence.

Answer:

B

Step-by-step explanation:

its a right angle and one point is 40 as shown already so 90-40=50 hope this helps

So you would take your 90° angle which is the box on the bottom right hand corner and add 40° which would equal 130° and then you would subtract 180° -130° and you would get 50°.

Answer:

The answer is C: 16, 32, 48, 64

Step-by-step explanation:

The multiples of 16 are:

16x1= 16

16x2=32

16x3=48

16x4=64

Answer:

Answer below. Hope it helps.

Step-by-step explanation:

a. 2x + (x - 6)    {x = 14}

= 2*14 + (14 - 6)

= 28 + 8

= 36

b. n² + n + 1    {n = 8}

= 8² + 8 + 1

= 64 + 9

= 73

c. (r - 10) (r + 2)    {r = 13}  

= (13 - 10) (13 + 2)

= 3 * 15

= 45

Answer:

look at the picture i sent......

Answer:

the answer is D.

Answer:

X³ – 3x² – 9x – 5

= x³ + x² – 4x² – 4x – 5x – 5

= x²( x + 1) – 4x ( x + 1) – 5(x + 1)

= (x + 1)(x² – 4x – 5)

= (x + 1)(x² -5x + x – 5)

= (x + 1)(x – 5) (x + 1)

hence, (x +1), (x -5) and (x +1) are the factors of given polynomial .

Answer:

The dependent variable is the number of plays he carries the ball.

The independent variable is the number of touchdowns he scores.

The dependent variable is the number of yards he gains.

Step-by-step explanation:

Tom's coach keeps track of the number of plays that Tom carries the ball and how many yards he gains. Select all the statements about independent and dependent variables that are true.

The dependent variable is the number of plays he carries the ball.

The independent variable is the number of plays he carries the ball.

The independent variable is the number of touchdowns he scores.

The dependent variable is the number of yards he gains.

The dependent variable is the number of touchdowns he scores.

y = kx

y = dependent variable. it is the variable that is explained by the dependent variable

x = is the variable that explains the dependent variable

we know that

1 ft--------> is equals to 12 in

the ramp is 12 inches tall----------> 1 ft tall

A ramp measures------------------>  6 ft long

applying the Pythagorean theorem

c²=a²+b²

where

c-----> 6 ft long

a----> horizontal distance

b-----> 1 ft tall

a²=c²-b²------> a²=6²-1²-----> a²=35------> a=√35------> a=5.92 ft

the answer is

5.92 ft

Answer:

6.08 or so

Step-by-step explanation:

The height is 1 foot, while the length is 6 feet.

You can use the Pythagorean Theorum to solve this, as you plug in the values.

The theorum states that A squared plus B squared = C squared, where A is  the length, and B is the width. (It doesn't matter if A is the width and B is the length either.)

So if we plug in the values:

1 squared plus 6 squared = C squared.

1 + 36 = 37

Since it is C squared, we can find the square root of 37, which is something like 6.0827625302982196889996842452021.

So usually we round to the hundredths place, so we can use 6.08.

Answer:

sin A = 13/85

Step-by-step explanation:

Opposite Angle A is side BC, of length 13.  The length of the hypotenuse is 85.  The sine function is defined as the ratio opp/hyp.  In this problem that ratio is

opp

------ = sin A = 13/85

hyp

We use the inverse sine function arcsin x to determine Angle A:

A = arcsin 13/85 = 8.8 degrees

Answer:

Sin(A) = [tex]\frac{13}{85}[/tex]

Step-by-step explanation:

Sin ratio = [tex]\frac{opposite}{hypotenuse}[/tex] (according to the given or asked angle)

Sin (A) = [tex]\frac{13}{85}[/tex]
