Answer:

1/8 meters

Step-by-step explanation:

The volume of a cube is given as the cube of the length of its sides. That is:

[tex]V = L^3[/tex]

where L = length of its side

The volume of the cube is 1/512 cubic metres.

This implies that:

[tex]\frac{1}{512} = L^3[/tex]

Find the cube root of both sides:

[tex]\sqrt[3]{\frac{1}{512} } = L\\\\=> L = \frac{1}{8}[/tex] meters

The cube has sides of length 1/8 meters

Answer:

4/5 book per hour

Step-by-step explanation:

In this question, we are to rewrite (2/5)/(1/2) as unit rate.

To write this as a unit rate, what we need to do

is to divide 2/5 by 1/2.

That means 2/5 divided by 1/2

Removing the division and replacing with multiplication will give 2/5 * 2/1 = 4/5 books/hour

Step-by-step explanation:

4/5 books/hour

Answer:

The height is 20

The max profit is 1600

Step-by-step explanation:

P (h) = -4h^2 + 160h

The vertex is at

-b/2a = -160/2(-4) = 160/8 = 20

The height that will give the maximum profit is 20

We want to find the value at 20

P(40)  =-4(20)^2 +160(20)

          =-1600+3200

             1600

2 1/4 = t

Answer: 9/4

Step-by-step explanation:

Answer:

Option (D).

Step-by-step explanation:

In the figure attached,

Triangle ACB is a right triangle having,

Leg AC = b = 13

Leg BC = a

Angle A = 76°

and, Hypotenuse AB = c

By applying tan rule in the given triangle,

tanA = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(76)° = [tex]\frac{BC}{AB}[/tex]

             = [tex]\frac{a}{b}[/tex]

4.01 = [tex]\frac{a}{13}[/tex]

a = 13 × 4.01

a = 52.13

a ≈ 52.1

Therefore, Option (D). will be the answer.

Answer:

52.1

Answer:

c

Step-by-step explanation:

I'm not sure but i hope this helps

Answer:

Let's solve your equation

[tex]x^2+13=8x+37[/tex]

Step 1: Subtract 8x+37 from both sides.

[tex]x^2+13-(8x+37)=8x+37-(8x+37)[/tex]

[tex]x^2-8x-24=0[/tex]

For this equation: a= 1, b= -8, c= -24

Step 2: Use quadratic formula with a=1, b=-8, c=-24.

[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex]

[tex]x=\frac{-(-8)+\sqrt{(-8)^2-4(1)(-24)} }{2(1)}[/tex]

[tex]x=\frac{8+\sqrt{160} }{2}[/tex]

[tex]x=4+2\sqrt{10}[/tex]   or  [tex]x=4-2\sqrt{10}[/tex]       This is the answer

So,the correct option is C

I hope this help :)

Answer:

5x² - 13x + 71

Step-by-step explanation:

We are to subtract 3x²+7x-43 from 8x²-6x+28

That is:

8x² - 6x + 28 - (3x² + 7x - 43)

8x² - 6x + 28 - 3x² - 7x + 43

Collect like terms:

8x² - 3x² - 6x - 7x + 28 + 43

5x² - 13x + 71

Answer:

the answer 5x² - 13x + 6

Answer:

27

Step-by-step explanation:

Kinetic energy = [tex]\frac{1}{2} m*v^2[/tex]

m = 6

v = 3

3 * 9 = 27

KE = 0.5 m.v^2

= 0.5*6*3^2

=27J

Answer:

-6 = x

Step-by-step explanation:

2x-8=4(x+1)

Distribute

2x -8 = 4x+4

Subtract 2x

2x-8-2x = 4x-2x+4

-8 = 2x+4

Subtract 4

-8-4 = 2x+4-4

-12 = 2x

Divide by 2

-12/2 = 2x/2

-6 = x

Answer:

[tex]x = - 6[/tex]

Step-by-step explanation:

[tex]2x - 8 = 4(x + 1) \\ 2x - 8 = 4x + 4 \\ 2x - 4x = 8 + 4 \\ - 2x = 12 \\ \frac{ - 2x}{ - 2} = \frac{12}{ - 2} \\ x = - 6[/tex]

Answer:

15.5 feet

Step-by-step explanation:

Find attached to this answer the appropriate diagram.

We would be using the Pythagoras Theorem to solve this question

The formula is given as:

a² + b² = c²

Where a = opposite side

b  = adjacent side

c = hypotenuse

From the question,

a = opposite side =  unknown

b  = adjacent side = 7 feet

c = hypotenuse = 17 feet

We are to find the opposite side

Using the formula

a² + b² = c²

a² = c² - b²

a² = 17 feet² - 7 feet ²

a² = 289 feet² - 49 feet²

a² = 240 feet²

a = √240 feet²

a = 15.491933385 feet

Approximately 15.5 feet

Therefore, the kite is 15.5 feet high up in the tree.

Answer:

[tex]4,080grams[/tex]

Step-by-step explanation:

the formula for density is:

[tex]d=\frac{m}{V}[/tex]

where d is density, m is mass, and V is volume.

solving for m in the last equation:

[tex]m=d*V[/tex]

so if we find the volume and multiply it by the density [tex]d=8.3gr/cm^3[/tex]  we will get the mass of the object.

The volume of a rectangular prism is given by:

[tex]V=l*w*h[/tex]

where [tex]l[/tex] is length, [tex]w[/tex] is width and [tex]h[/tex] is height:

[tex]l=5in\\w=3in\\h=2in[/tex]

we substitute to find the volume:

[tex]V=5in*3in*2in\\V=30in^3[/tex]

since the density has units of [tex]cm^3[/tex] we need the volume also in units of [tex]cm^3[/tex] , so we make the conversion using:

[tex]1in^3=16.3871cm^3[/tex]

multiplying by 30:

[tex]30in^3=491.612cm^3[/tex]

and now we find the mass with the equation:

[tex]m=d*V[/tex]

substituting d and V:

[tex]m=(8.3gr/cm^3)(491.612cm^2)\\m=4,080.36gr[/tex]

the nearest gram is: [tex]4,080grams[/tex]
