Answer:

2.25

Step-by-step explanation:

I think it is this in fraction form 2 1/4

Answer:

x = 20°

Step-by-step explanation:

here's your solution

=> it is given that whole angle is 90°

=> so, x + (3x + 10) = 90°

=> x + 3x + 10 = 90°

=> 4x + 10 = 90°

=>4x = 90 - 10

=> 4x = 80°

=.

=> x = 80/4

=> x = 20°

one angle is 20° and other 70°

hope it helps

Answer:

20 is your answer

x+3x+10=90 being right angle

4x=90-10

x=80/4=20

Responda:

21 dias

Explicação passo a passo:

Total de dias necessários = 70 dias

Dias usados ​​no mês 1 = 25 dias

Dias usados ​​no mês 2 = 24 dias

Dias usados ​​no total = 24 + 25 = 49 dias

Dias restantes :

70 dias - 49 dias

= 21 dias

Answer:

Step by step

Step-by-step explanation:

Since we have the endpoints of the diameter, the midpoint coordinates of the line segment joining them gives the centre of the circle.

That is, centre (a,b) = ( [1+(-3)]/2, [4+2]/2) = (-1,3)

Distance between the given points give the diameter and half of that is the radius length.

So, radius r = (1/2)* sqrt ( [1-(-3)]^2 + [4–2]^2) = sqrt(5)

Thus equation required is: (x-a)^2 + (y-b)^2 = r^2

So, (x+1)^2 + (y-3)^2 = 5

The equation of the circle is (x + 1)² + (y - 3)² = 5

The endpoints of the diameter are given as:

(1, 4) and (−3, 2)

Start by calculating the midpoint using:

Midpoint = 0.5 * (x₁ + x₂, y₁ + y₂)

So, we have:

Midpoint = 0.5 * (1 - 3, 4 + 2)

Evaluate

Midpoint = (-1, 3)

So, the center (a,b) of the circle is:

(a,b) = (-1,3)

Calculate the length of the diameter using:

D² =(x₁ - x₂)² + (y₁ - y₂)²

This gives

D² = (1 + 3)² + (4 - 2)²

D² = 20

Take the square roots

D = 2√5

Divide by 2 to calculate the radius

r = √5

Square both sides

r² = 5

The equation of the circle is then represented as:

(x - a)² + (y - b)² = r²

This gives

(x + 1)² + (y - 3)² = 5

Hence, the equation of the circle is (x + 1)² + (y - 3)² = 5

Answer:

See Below.

Step-by-step explanation:

The first three terms of an A.P is equivalent to the first three terms of a G.P.

We want to show that this is only possible if r = 1 and d = 0.

If a is the initial term and d is the common difference, the A.P. will be:

[tex]a, a+d, \text{ and } a+2d[/tex]

Likewise, for the G.P., if a is the initial term (and it does not equal 0) and r is the common ratio, then our sequence is:

[tex]a, ar,\text{ and } ar^2[/tex]

The second and third terms must be equivalent. Thus:

[tex]a+d=ar\text{ and } a+2d=ar^2[/tex]

We can cancel the d. Multiply the first equation by -2:

[tex]-2a-2d=-2ar[/tex]

We can now add this to the second equation:

[tex](a+2d)+(-2a-2d)=(ar^2)+(-2ar)[/tex]

Simplify:

[tex]-a=ar^2-2ar[/tex]

Now, we can divide both sides by a (we can do this since a is not 0):

[tex]-1=r^2-2r[/tex]

So:

[tex]r^2-2r+1=0[/tex]

Factor:

[tex](r-1)^2=0[/tex]

Thus:

[tex]r=1[/tex]

The first equation tells us that:

[tex]a+d=ar[/tex]

Therefore:

[tex]a+d=a(1)\Rightarrow a+d=a[/tex]

Hence:

[tex]d=0[/tex]

Answer:

1296 sq inches

Step-by-step explanation:

To start, you need to get the total area of each individual roll of wrapping paper. To do this, you need to multiply the length x width, which would be 18 x 24 = 432. Then, you have three rolls so you mutiply that by three, which is 432 x 3 = 1296. You add the unit, and that leaves you with 1296 sq inches.

Answer: B

`sqrt(8x^3 + 24x^2 + 18x)` = `sqrt(8x (x + 3/2))` = `sqrt(2x (4x + 6))` = ±(4x + 6) `sqrt(2x)`

Answer:

86.6 ft.

Step-by-step explanation:

Answer:  x= -6; y= -1

Step-by-step explanation:

-4x + y = 23

4x - 9y = - 15

-4x + y = 23

      y = 23 + 4x     [Add 4x to both side]

4x - 9(23 + 4x) = - 15

4x - 207 - 36x = - 15

-32x - 207 = -15

-32x = 192             [Add 207 to both side]

    x = -6                [Divide -32 from both side]

-4x + y = 23

-4(-6) + y = 23          [Plug in -6 for x]

24 + y = 23              [Subtract 24 from both side]

       y = -1

Answer:

21 < x < 27

Step-by-step explanation:

Given that :

Side 1 = 23

Side 3 = x

Side 2 = 2x - 4

23 + x > 2x - 4

Collect like terms

x - 2x > - 4-23

-x > - 27

x < 27

Also ;

23 + 2x - 4 > x

23 - 4 > x - 2x

21 > - x

-21 < x

x > - 21

Hence,

Possible values of x :

x > 21 and x < 27
