Answer:

hour hand = 7.5 x 2 for the diameter. C = 2(pi)(15) = approx. 94 centimeters. Minute hand = 9.5 x 2 = 19, C = 2(pi)(19) = approx. 119 centimeters

Step-by-step explanation:

Answer:

Step-by-step explanation:

By the Pythagorean Theorem

[tex]c^2=a^2+b^2\\ \\ c^2=60^2+32^2\\ \\ c^2=4624\\ \\ x=\sqrt{4624}\\ \\ x=68[/tex]

Answer:

(5a²+4b³)³= 64b^9+240a^2b^6+300a^4b^3+125a^6

(2xy-1)³= 8x^3y^3−12x^2y^2+6xy−1

(3m-2n)= 0

(f+5)³=​ f^3+15f^2+75f+125

Step-by-step explanation:

(5a²+4b³)³  =  [tex]64b^{9} + 240a^{2} b^{6} + 300a^{4} b^{3} + 125a^{6}[/tex]

(2xy-1)³  = [tex]8x^3y^3 - 12x^2y^2 + 6xy - 1[/tex]

(3m-2n)  =  3m - 2n

(f+5)³  =​  [tex]f^3 + 15f^2 + 75f + 125[/tex]

Answer:

it should be x=2 or x=--4

Answer:

The perimeter of a rectangle is equal to 2L + 2W, where L = the length of the rectangle and W = the width of the rectangle. So, one equation is

2L + 2W = 60

From the info given in the problem, we also know that L = 4W. Therefore, we can use the Substitution Method to re-write the first equation as:

4W + 2W = 60

You should be able to solve this equation for W. Once you find W, you can then calculate L.

Actually Welcome to the Concept of the linear pair.

Applying it we get as,

==> PQR + RQS = 180°

hence angle PQR = 150°

Answer:

9

Step-by-step explanation:

so we know that its a right triangle and 8 and [tex]\sqrt{17}[/tex] are not the hypotenuse.

the equation for this is [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex] with c being the hypotenuse.

[tex]8^{2}[/tex]+[tex]\sqrt{17} ^{2}[/tex]=[tex]c^{2}[/tex]

64+17=[tex]c^{2}[/tex]

81=c

[tex]\sqrt{81}[/tex]=c

9=c

Answer:

Step-by-step explanation:

To make the use of Pythagoras's theorem clear

[tex]C^{2}[/tex] = [tex]A^{2}[/tex] + [tex]B^{2}[/tex]

where C is they hypotenuse or Hyp

A is one side often called  the Adjacent side

B is the other side often called the Opposite side

when A = 8

and B = [tex]\sqrt{17}[/tex]

then

[tex]C^{2}[/tex]  = [tex]8^{2}[/tex] + [tex]\sqrt{17} ^{2}[/tex]

[tex]C^{2}[/tex] = 64 + 17

[tex]C^{2}[/tex] = 81

C = [tex]\sqrt{81}[/tex]

C = 9

Answer:

  the diagonals are congruent

Step-by-step explanation:

If the base angles of a trapezoid are congruent, it is an isosceles trapezoid. It will be symmetrical about its center line. Each half of the trapezoid is identical (mirror image) to the other half. The diagonals are the same length.

Answer:

Step-by-step explanation:

-2x - 14 > -4 + 3x

subtract 3x from both sides

-5x - 14 > -4

add 14 to both sides

-5x > 10

divide both sides by -5

x < -2

The answer would be -5x > 10.

This is because our last inequality was -5x - 14 > -4 so we add 14 to both sides and it would look like this -5x (-14 + 14) > (-4 + 14) which would transition into our next inequality -5x > 10.

So therefore the answer would be -5x > 10.

Answer:

90

Step-by-step explanation:

X/10-4=5

add 4 to both sides

X/10=9

mulitiple 10 to both sides

X=90

Answer:

V = πr²h

Step-by-step explanation:

r = radius of circle

h = height of cylinder

Step-by-step explanation:

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h . ... Therefore, the volume of the cylinder is about 3016 cubic centimeters.

Answer:

$758 per week

Step-by-step explanation:

15.16 x 50 = 758

Answer:$758 per week

Step-by-step explanation:Answer:15.16 x 50 = 758

Step-by-step explanation:

1. Given,

Side of the cube = 9 cm

Therefore, volume of the cube = side × side × side

= 9cm × 9cm × 9cm

[tex] = 729 {cm}^{3} (ans)[/tex]

2. Given,

Length of the rectangle = 4cm

Breadth of the rectangle = 3cm

Therefore, perimeter of the rectangle = 2(l+b)

= 2(4cm + 3cm) = 2 × 7cm = 14 cm (Ans)

3. Given,

Side of a square = 11 m

Therefore, area of the square = side × side

= 11 m × 11 m

[tex] \: = {121cm}^{2} (ans)[/tex]

4. Given,

Length of the rectangle = 14 m

Width of the rectangle = 5 m

Therefore, area of the rectangle = l × b

= 14 m × 5 m

[tex] = 70 {m}^{2} (ans)[/tex]

5. Given,

Side of the equilateral triangle = 15 cm

Therefore, perimeter of the triangle = 3 × side

= 3 × 15 cm = 45 cm (Ans)

Answer:

16

Step-by-step explanation:

3 miles = 2 days

24 miles = ? days

24 / 3 = 8

8 x 2 = 16

Answer:

16 days

Step-by-step explanation:

[tex]\frac{3}{2}[/tex] to represent the relationship from miles to days

[tex]\frac{3}{2}[/tex]=[tex]\frac{24}{x}[/tex]

3 x 8 = 24

so do the same thing to 2

2 x 8 = 16 days
