Answer: 4,187 in3

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a sphere: 4/3 π (diameter /2)^3

Replacing with the values given;

V = 4/3 (3.14) (20/2)^3 = 4/3 (3.14) 10^3 =4,187 in3

The volume of the sphere is 4,187 cubic inches.

Answer:x=4

Step-by-step explanation:

Do your distribution rules to get -3x+12+7=4x-9. Then combine like variables to get -3x+19=4x-9. Add the 9 to 19 and get 28 then add the 3 to 4 to get 7. Should look like 28=7x. Divide the 7 to 28 and get the answer of 4

Answer:

X=4

Step-by-step explanation:

-3(x-4)+7=4x-9

-3x(12)+7=4x-9

+3x         +3x

      12+7=7x-9

         +9   +9

      12+16=7x

          28=7x

  The transformation is rigid because corresponding side lengths and angles are congruent

Step-by-step explanation:

The problem statement tells you angles and side lengths are unchanged, so any answer choice contradicting that can be rejected.

Whether a transformation is rigid or not has nothing to do with naming, so you can reject the "different names" answer choice.

The true statement is ...

  The transformation is rigid because corresponding side lengths and angles are congruent

Answer:

A

Step-by-step explanation:

1 yard = 36 inches

1 feet = 2 foots = 24 inches

First time, she's got 5315 inches, second time is 5868 inches

5315 + 5868 = 11183 inches

11183 : 36 = 310.638888889 inches

Change it and we have answer A, 311 yards 11 inches

Answer: every year there is an 81% addition to the mass of the sample

Step-by-step explanation:

Khan academy told me

The yearly percent change in the mass of the sample will be 81.06%.

The quantity of anything is stated as though it were a fraction of a hundred.

A sample of a mysterious chemical substance naturally gains mass over time.

The relationship between the elapsed time t, in years, since the mass of the sample, M(t), in grams, was initially measured is modeled by the following function:

[tex]\rm M(t) = (1.16)^{4t+3}[/tex]

The yearly percent change in the mass of the sample will be

At t = 0, we have

M(0) = (1.16)³ = 1.561

At t = 1, we have

M(1) = (1.16)⁷ = 2.826

Then the percentage will be

P = [(2.826 – 1.561) / 1.561] x 100

P = 0.8106 x 100

P = 81.06%

Answer:

x=2

Step-by-step explanation:

triangle area is 1/2BH

1/2(4x)=4

2x=4

x=2 units

Answer:

Missing side = 2

X= 2

Have given details if x was only base of the side triangle

This is in order to find a completely new triangle with just the height and in order to find and combine 1 given area say if just the right side in your diagram was 4 and we had to find the other triangle. This is only done on scale or 1 given measure or angle for the right side triangle. We was not given this but proved a 0.3 scale.

Area of other triangle =2.66^2

2.66+4 combined = 6.66^2

Step-by-step explanation:

We find a square height is also 4

We also know a right angle triangles height can be found using either 1/2 base or 1/2 height.

So this can mean the height is and stays 4 and the base is 2.

As 1/2  4 height = 2 height

2 unit height x 2 unit base = 4

Therefore, the first triangle slant is the same.

4sq +2sq = c^2

√16+√4 = √20

c^2 = √20 = 4.47     = 4.472135955

c = 4.47 slant

Given a=4 and c=4.47,

b = 1.99522

∠α = 63.49° = 63°29'23"

∠β = 26.51° = 26°30'37"

h = 1.78543

We cna tell now that the triangle is 0.333 smaller so the measurements

Show 2/3 of 2 = 1.333 being the base across

using this as Area we find 1.333 x 2 =  2.666

(1/2 h^b of 4) =2

We can prove with the angles

63 +27 degree or

a^2+b^2 = c^2

1.333^2 + 4^2

= √1.776889+√ 16 = √ 17.776889

c^2 = 4.21626481616

c= 4.22 slant left side  (nb right side on attachment)

Angle ∠ A = α = 71.478° = 71°28'39″

Angle ∠ B = β = 63.53° = 63°31'48″

Angle ∠ C = γ = 44.992° = 44°59'33″

We see 63 angle on right lower side of attachment picture in reflection and can prove x = 3.333

But on your diagram base x = 2

What i have done is enlarged x by 0.3 and proven  how to find x if x was just one side of the triangle's height.

The triangles even though reflected are identical.

Other info is proven through finding ha and hb heights.

We confirm 4.001 is the hc height of your diagram.

Height: ha = 2.984

Height: hb = 3.16

Height: hc = 4.001

Answer:

x = -1 and x = 3

Step-by-step explanation:

f(x)= x^2-2x-3

f(x) = (x + 1) (x - 3)

Therefore, x = -1 and x = 3

The zeroes of the quadratic function f(x) = x² + 2x - 3 will be 1 and negative 3.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.

The quadratic equation is given below.

f(x) = x² + 2x - 3

Then the factor of the quadratic equation will be

f(x) = x² + 2x - 3

f(x) = x² + 3x - x - 3

f(x) = x(x + 3) - 1(x + 3)

f(x) = (x + 3)(x - 1)

The zeroes of the function will be

f(x) = 0

(x + 3)(x - 1) = 0

x = 1, -3

Then the zeroes of the quadratic function f(x) = x² + 2x - 3 will be 1 and negative 3.

Step-by-step explanation:

Answer:

1/6

Step-by-step explanation:

Answer:Yes

Step-by-step explanation:

Given

Suppose side length of cube is a

If we dilate the cube using a scale factor of 2

Side length becomes 2a

and the surface area becomes [tex]=6(\text{side length})^2[/tex]

Surface area[tex]=6(2a)^2[/tex]

Surface area[tex]=4\times 6(a)^2[/tex]

Thus surface area multiplied by a factor of 4

Now for volume

[tex]V=(\text{side length })^3[/tex]

[tex]V=(2a)^3[/tex]

[tex]V=8(a^3)[/tex]

Therefore volume is multiplied by a factor of 8

Therefore the above statements make sense
