Answer:

(d) They may be combines

Step-by-step explanation:

Given

[tex]6\sqrt{32} - 12\sqrt{72}[/tex]

Required

Which option is true

Express 32 as 16 * 2 and 72 as 36 * 2

[tex]6\sqrt{32} - 12\sqrt{72} = 6\sqrt{16 * 2} - 12\sqrt{36 * 2}[/tex]

Split

[tex]6\sqrt{32} - 12\sqrt{72} = 6\sqrt{16} * \sqrt{2} - 12\sqrt{36} * \sqrt{2}[/tex]

This gives:

[tex]6\sqrt{32} - 12\sqrt{72} = 6*4 * \sqrt{2} - 12*6 * \sqrt{2}[/tex]

[tex]6\sqrt{32} - 12\sqrt{72} = 24 * \sqrt{2} - 72 * \sqrt{2}[/tex]

[tex]6\sqrt{32} - 12\sqrt{72} = 24 \sqrt{2} - 72 \sqrt{2}[/tex]

Since both term have the same radicand, then:

[tex]6\sqrt{32} - 12\sqrt{72} =( 24 - 72 )\sqrt{2}[/tex]

[tex]6\sqrt{32} - 12\sqrt{72} =-48\sqrt{2}[/tex]

Option (d) is correct

Answer: 1350

Step-by-step explanation:

6*15^2=1350 in

A=1350 in

The surface area of the cube is 1350 in.

Answer:

if what you're asking if 0 belongs to anyone of the sets then zero belongs to whole numbers.

whole numbers is 0,1,2,3,4 etc

Natural numbers are 1,2,3,4 etc

integers are -3,-2,-1,0,1,2,3 etc

rational numbers are like fractions etc

irrational numbers are when you don't necessarily get a exact or whole numbers for example like π/pie

Answer:

1. draw a circle inside the triangle

2. draw a circle through those dots

3. draw a circle outside the triangle but through the dots

4. create a triangle with the same angle and length and draw a circle inside that triangle

5. Draw a right triangle (with 90 degrees; could be 45-90-45 or 30-60-90)

a. hypotenuse is the diameter of the circle

b. hard to explain but it should look like this: (link)

Answer:

????????????......???????.

the distance between Dan and jeff is 26 feet

Answer:

Angle A is 52 degrees           Angle B is 78 degrees

Step-by-step explanation:

The angles all have to add up to 180.

2x + 3x + 50 = 180

5x + 50 = 180

Subtract 50 from both sides

5x = 130

Divide each side by 5

x = 26

Solve

A) 2 * 26 = 52

B) 3 * 26 = 78

--------Check--------

52 + 78 +50 = 180

180 = 180

[tex] - 12 - 3y \geq - 6x \\ - 12 - 3y + 12 \geq - 6x + 12 \\ - 3y \geq - 6x + 12 \\ = \frac{ - 3y}{ - 3} \geq \frac{ - 6x + 12 }{ - 3} \\ y = 2x - 4 [/tex]

Correct me if I'm wrong

I hope it helps ^_^

Answer:

Step-by-step explanation:

a). Volume of a rectangular prism = Length × width × height

                                                        = 13 × 8 × 12

                                                        = 1248 cubic ft

     Surface area of a rectangular prism = (lb + bh + hl)

     Here, l = length, b = width and h = height of the rectangular prism

     Surface area of the given prism = (13×8 + 8×12 + 12×13)

                                                           = 356 square ft

b). If the shed is made of metal,

    Metal needed to make the shed = Volume

c). The shed is used for the storage.

    Measure would be used → Surface area

Answer:

area = 828.27 cm²

Step-by-step explanation:

add a line from X, perpendicular to WY, call this point A.

angle Y = 180 - 33 - 121 = 26 degrees

sin 26 = XA/49

0.4384 = XA/49

XA = 21.48 which is the height of the triangle

cos 26 = YA/49

0.8988 = YA/49

YA =  44.04

tan 33 = 21.48/WA

0.6494 = 21.48/WA

WA = 33.08

YW = 77.12

(YW)(XA)(0.5) = area

(77.12)(21.48)(0.5) = area = 828.27 cm²

Answer:

(12, -3)

Step-by-step explanation:

Add 4 to x value because it is a horizontal translation right 4.

Answer:

Step-by-step explanation:

Example 1:

Evaluate the following expression:

4 + (3x +y)

When x = 2 and y = 9

3 x 2 is 6 after that you just add 6+9+4 which is 19

Example 2:

Evaluate the expression when x=8 and y=9

x(y - 9)^3 + 2

=8(9-9)^3+2

=8(0)^3+2

=8(0)+2

=0+2

=0

Answer:

do you mean seconds in an hour?

Step-by-step explanation:

Answer:

Medium

Step-by-step explanation:

The computation is shown below:

The cost for the small and medium bag is shown below:

As we know that

1kg = 1000g

So 3kg = 3000g

Now for small bags

= 0.95 ÷ 250 × 3000

= £11.40

For medium bags

= £1.80 ÷ 500 × 3000

= £10.80

So here the medium bag would represent the better value

Answer:

6 is your answer

Given:

The three equations for the three numbers are

[tex]a=x^2-y^2[/tex]

[tex]b=2xy[/tex]

[tex]c=x^2+y^2[/tex]

To find:

The Pythagorean triple generated by using 4 for x and 1 for y.

Solution:

Substituting x=4 and and y=1 in the given equations, we get

[tex]a=4^2-1^2[/tex]

[tex]a=16-1[/tex]

[tex]a=15[/tex]

In the same way find b and c.

[tex]b=2(4)(1)[/tex]

[tex]b=8[/tex]

The third number is

[tex]c=4^2+1^2[/tex]

[tex]c=16+1[/tex]

[tex]c=17[/tex]

The required Pythagorean triple is 8, 15, and 17.

Therefore, the correct option is C.
