Answer:

Step-by-step explanation:

Answer: The length of the third side is greater than 4 ft and less than 20 ft.

Step-by-step explanation: Given that two sides of a triangle have lengths 8 ft and 12 ft.

We are to describe the possible lengths of the third side.

Let x ft be the length of the third side of the triangle.

We know that

the sum of the lengths of any two sides of a triangle is always greater than the third side.

So, we must have

Also,

and

From inequalities (i), (ii) and (iii), we get

Thus, the length of the third side is greater than 4 ft and less than 20 ft.

Please consider the graph of the sphere.

We know that the volume of sphere is equal to $\frac{4}{3}\pi r^3$ , where r represents radius of sphere.

We can see that diameter of sphere is 30 inches. We know that radius is half the diameter, so radius of the given sphere would be half of 30 inches that is $\frac{30}{2}=15$ inches.

$V=\frac{4}{3}\pi r^3$

$V=\frac{4}{3}\pi (15\text{ in})^3$

$V=\frac{4}{3}\pi \times 3375\text{ in}^3$

$V=4\times 1125\pi \text{ in}^3$

$V=4500\pi \text{ in}^3$

Therefore, the volume of the given sphere is $4500\pi\text{ in}^3$ and option B is the correct choice.

Rotate angle ABC 90 degrees clockwise about the origin and then reflect over the x-axis

Lady_Fox [76]

Rotation and reflection are instances of transformation

See attachment for the new position of $\triangle ABC$

From the question, we have:

$A = (-1,1)$

$C = (-2,4)$

The rule of 90 degrees clockwise rotation is:

$(x,y) \to (y,-x)$

Using the above transformation, the new points would be

$A' = (1,1)$

$B' =(3,3)$

$C' = (4,2)$

The next transformation is reflection over the x-axis

The rule of this transformation is:

$(x,y) \to (x,-y)$

So, the new points would be:

$A" = (1,-1)$

$B" = (3,-3)$

$C" = (4,-2)$

See attachment for the new points

Can you Just pls Tell me the answer

andrew11 [14]

Answer:

1. Equation is x - 5 = 8

x = 13

2. Equation is 4x - 4 = 10

x = 3.5

3. Equation is x/4 = 8

x = 32

4. Equation is 5x = 10

x = 2

5. Equation is x - 5 / 2 = 14

x = 33

6. Equation is 4x / 5 = 10

x = 12.5

7. Equation is 2x - 10 = 8

x = 9

8. Equation is 3x + 6 / 3 = 10

x = 8

9. Equation x + 8 / 4 = 14

x = 48
