Problem ID: PRABMTFA A solid with volume 12 cubic units is dilated by a scale factor of k. Find the volume of the image for each given value of k.
k=1/4

Answers

Answer:

Step-by-step explanation:

3/16

You can use the fact that you can think of the solid as made up of 12 cubes with side length of 1 unit.

The volume of the image of the dilated solid is for k = 1/4 is

3/16 cubic units

How can we interpret measurement of something?

Remember that volume, area, length etc all are measured relatively.

If you are 1.7 meters tall, then you're height is measured relative to meters. This is called unit of the measurement. It means that if we collect 1 meter and 0.7 meters too,they together will be equally tall as you.

Similarly, if we say that a triangle has area of 40 square inches, then it means that its area is equal to 40 squares of 1 inch sides.

Using above understanding to find the volume of the dilated solid

Since the original solid was of 12 cubic units. it means its volume was equal to the total volume of 12 cubes with 1 unit side length.

Now since the scale factor of the dilation is k, that means each of the cube got its side length multiplied by k

Now  volume of 12 cubes with side length k units is given by

[tex]V = 12 \times k^3[/tex]

Since it is given that k = 1/4, we have:

[tex]V = 12 \times (\dfrac{1}{4})^3 = \dfrac{3}{16} \: \rm unit^3[/tex]  now there are 3/16 cubes with 1 unit length.

Thus,

The volume of the image of the dilated solid is for k = 1/4 is

3/16 cubic units

2x - x + 7 = x + 3 + 4

Answers

Answer:0

Step-by-step explanation:

Simplifying

2x + -1x + 7 = x + 3 + 4

Reorder the terms:

7 + 2x + -1x = x + 3 + 4

Combine like terms: 2x + -1x = 1x

7 + 1x = x + 3 + 4

Reorder the terms:

7 + 1x = 3 + 4 + x

Combine like terms: 3 + 4 = 7

7 + 1x = 7 + x

Add '-7' to each side of the equation.

7 + -7 + 1x = 7 + -7 + x

Combine like terms: 7 + -7 = 0

0 + 1x = 7 + -7 + x

1x = 7 + -7 + x

Combine like terms: 7 + -7 = 0

1x = 0 + x

1x = x

Solving

1x = x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.

1x + -1x = x + -1x

Combine like terms: 1x + -1x = 0

0 = x + -1x

Combine like terms: x + -1x = 0

0 = 0

Simplifying

0 = 0

The solution to this equation could not be determined.

Answer:

a) 46° b) 66° c) 4 cm

Step-by-step explanation:

a) because it is isosceles triangle, therefore, 2 opposite angles, and angle sum of triangle is 180 so 180-67-67=46

b) because again, isosceles triangle so two opposite sides,

x+x+48=180

2x=132

x=66

c)because it is equilateral, so therefore all angles are 60 degrees and all sides equal.

Step-by-step explanation:

The formula for area is: length x width.

The length is 9 in or (using the scale) 18 ft.

What is the solution to this set of equations?
2x+2y=6
x-y=3

Which answer is correct?
(0,-3)
(3,0)
(6,3)
(0,3)

Answers

Answer:

(3,0)

Step-by-step explanation:

2x + 2y = 6  divide thru by 2 and you get  x + y = 3  

Name   x + y = 3  equation (1) and  x - y = 3 equation (2)

Add equations (1) and (2)  

 (1)   x+ y = 3

 (2) x - y = 3    

        2x = 6

          x = 3  

Substitute x = 3 into equation (1).  So, 3 + y = 3

                                                                    y = 0

Area of the Composite Figure:

16in

Answers

Answer:

86.14 in.²

Step-by-step explanation:

Area of the composite figure = area of semicircle + area of rectangle + area of triangle

= (½πr²) + (L*W) + (½bh)

Where,

r = ½*6 = 3 in.

L = 8 in.

W = 6 in.

b = 16 - 8 = 8 in.

h = 6 in.

Plug in the values and solve

Area of composite figure = (½*π*3²) + (8*6) + (½*8*6)

= 14.14 + 48 + 24

= 86.14 in.²

Answers

Answer:

3+x sqrt 7 -13 is a radical equation.

The value of radical equation is,

⇒ 7√x = 14

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

All the equations are,

⇒ x +√5 = 12

⇒ x² = 16

⇒ 3 + x√7 = 13

⇒ 7√x = 14

Since, A radical equation is an equation with at least one variable put on a radical form.

In this question, there is only one kind of variable which is x.

Then, you need to find the equation where x is in the radical form.

Hence, The radical form can be expressed with square root symbol.

Therefore, The option with √x would be only,

⇒ 7√x = 14

Thus, The value of radical equation is,

⇒ 7√x = 14
