The volume of a sphere is 36ft. What is the radius

Answer: $139.23

Step-by-step explanation: Take 50% of original dress price and add price of shoes. Subtract 10% of that.

I assumed you are referring to the Net (take away by the seller after removing their commissions).

Answer:

Selling price

Step-by-step explanation:

To determine what amount goes to the seller, we multiply the selling price of a commodity in question by the percentage (commissions) to the seller.

Note that the resulting amount is the value of the commission paid to the seller, the actual net is gotten by substracting the selling price from the commission paid.

Answer:

w=6

Step-by-step explanation:

Since the triangles are similar, we can use ratios to solve

4          3

----- = --------

8           w

4w = 3*8

4w = 24

Divide by 4

4w/4 = 24/4

w = 6

Answer:

As hard as this may seem, it's actually quite simple. Because these two figures are similar, their sides can be compared.

See how on the left side of both of the triangles the numbers are 4 and 8? This shows that the left triangle is twice as small as the right one, which means that if you multiply any of the sides of the triangle on the left by 2, you'll get the triangle on the right.

We can apply this to w. Look at the left triangle on the bottom and see how there is a 3. Well, we've already noticed how the triangle on the left just needs to be multiplied by 2 in order to get to the one on the right, so that's what we should do! When you multiply 3 by 2, you get 6 which is w.

So, long answer short, w is 6.

The measure of each side of the cube will be 15 inches.

The Volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. Volume is defined as the space occupied by an object in the three-Dimensions. All three parameters are required for the volume like length, width, and height of the cube or Cuboid

The cube has all the sides equal means that the length, width, and height of the cube will be the same. Let's suppose the length, width, and height of the cube is a.

The volume of a cube will be given by the formula:-

Volume = side³ = a³

a³ = 3375

a = ∛3375

a = ∛( 15 x 15 x 15 )

a = 15 cubic inches.

Therefore, the measure of each side of the cube will be 15 inches.

Answer:

If thrown up with the same speed, the ball will go highest in Mars, and also it would take the ball longest to reach the maximum and as well to return to the ground.

Step-by-step explanation:

Keep in mind that the gravity on Mars; surface is less (about just 38%) of the acceleration of gravity on Earth's surface. Then when we use the kinematic formulas:

[tex]v=v_0+a\,*\,t\\y-y_0=v_0\,* t + \frac{1}{2} a\,\,t^2[/tex]

the acceleration (which by the way is a negative number since acts opposite the initial velocity and displacement when we throw an object up on either planet.

Therefore, throwing the ball straight up makes the time for when the object stops going up and starts coming down (at the maximum height the object gets) the following:

[tex]v=v_0+a\,*\,t\\0=v_0-g\,*\,t\\t=\frac{v_0}{t}[/tex]

When we use this to replace the 't" in the displacement formula, we et:

[tex]y-y_0=v_0\,* t + \frac{1}{2} a\,\,t^2\\y-y_0=v_0\,(\frac{v_0}{g} )-\frac{g}{2} \,(\frac{v_0}{g} )^2\\y-y_0=\frac{1}{2} \frac{v_0^2}{g}[/tex]

This tells us that the smaller the value of "g", the highest the ball will go (g is in the denominator so a small value makes the quotient larger)

And we can also answer the question about time, since given the same initial velocity [tex]v_0[/tex] , the smaller the value of "g", the larger the value for the time to reach the maximum, and similarly to reach the ground when coming back down, since the acceleration is smaller (will take longer in Mars to cover the same distance)

Answer:

The  95% confidence interval is [tex]0.1193 < p <0.4407[/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  [tex]m = 30[/tex]

   The sample proportion is  [tex]\r p = 0.28[/tex]

Given that the confidence interval is  95% then the level of significance is mathematically represented as

           [tex]\alpha = 100 - 95[/tex]

           [tex]\alpha = 5\%[/tex]

          [tex]\alpha = 0.05[/tex]

Next we obtain the critical value of the [tex]\frac{\alpha }{2}[/tex] from the normal distribution table, the value is

        [tex]Z_{\frac{ \alpha }{2} } = 1.96[/tex]

Generally the margin of error is mathematically represented as

       [tex]E = Z_{\frac{ \alpha }{2} } * \sqrt{\frac{ ( \r p (1 - \r p ))}{n} }[/tex]

=>    [tex]E = 1.96 * \sqrt{\frac{ (0.28 (1 - 0.28 ))}{ 30} }[/tex]

=>   [tex]E = 0.1607[/tex]

The  95% confidence interval is  

     [tex]\r p - E < p < \r p + E[/tex]

=> [tex]0.28 - 0.1607 < p < 0.28 + 0.1607[/tex]

=> [tex]0.1193 < p <0.4407[/tex]

=====================================

Work Shown:

Multiply the first coefficient (6) and the last term (-7) to get -42. We need to find factors of -42 that add to -19

Turns out that those two numbers are -21 and 2, which you find by trial and error.

-21 * 2 = -42

-21 + 2 = -19

Break up -19x as -21x+2x and use the factor by grouping method

6x^2 - 19x - 7

6x^2 - 21x + 2x - 7

(6x^2 - 21x) + (2x - 7)

3x(2x - 7) + 1(2x - 7)

(3x+1)(2x-7)

The factorization represents the length*width, since this product is equal to the rectangle's area.

----------------------

Plug x = 15 into each factor

3x+1 = 3*15+1 = 46

2x-7 = 2*15-7 = 23

The length and width are 46 and 23

Answer:

Step-by-step explanation:

From the question

P=2L+2W

where

L is the length

W is the width

To make W the subject move 2L to the left side of the equation

That's

2W = P - 2L

Divide both sides of 2 to make W stand alone

We have

[tex]W = \frac{P - 2L}{2} [/tex]

when

P = 70

L = 22

W is

[tex]W = \frac{70 - 2(22)}{2} \\ W = \frac{70 - 44}{2} \\ W = \frac{26}{2} [/tex]

We have the final answer as

Hope this helps you

Answer:

Width W = 13

Step-by-step explanation:

P = 2L + 2W

if the perimeter P = 70

and Length L = 22

find the Width W

P = 2L + 2W

70 = 2(22) + 2W

70 - 44 = 2W

26 = 2W

W = 26 / 2

W = 13

therefore,

the Width W = 13

check:

P = 2L + 2W

70 = 2(22) + 2(13)

70 = 44 + 26

70 = 70   --- OK

Answer:

y= 2/3x +5

Step-by-step explanation:

(0,5) is the y intercept and the slope is 2/3 so we can use the y intercept form

y = mx+b where m is the slope and b is the y intercept

y= 2/3x +5

Answer:

y= 2/3x+5

Step-by-step explanation:

Okay, to write the equation of a line you need two values. The y intercept and the slope. The y intercept has an x coordinate of zero, and lucky us, the point you were given has an x coordinate of zero so that's done. You were also given the slope, so you don't have to calculate it. Anyways, the formula of a line is written in slope intercept form usually, so y=mx+b. Just fill in the gaps, m= the slope and b=the y intercept. The slope is 2/3, and the y intercept is 5. So, inserting in the variables you get y=2/3x+5.

[tex]100632_{10} = 11000100100011000_{2}[/tex]

Step-by-step explanation:

Given

a) 321

b) 1023

c) 100632

Required

Convert to decimal

To convert each of these to binary, we have to divide the quotient by 2 and we take note of the remainder;

Solving (a)

321 / 2 = 160 R 1

160 / 2 = 80 R 0

80 / 2 = 40 R 0

40 / 2 = 20 R 0

20 / 2 = 10 R 0

10 / 2 = 5 R 0

5 / 2 = 2 R 1

2 / 2 = 1 R 0

1 / 2 = 0 R 1

Hence;

[tex]321_{10} = 101000001_{2}[/tex]

Solving (b)

1023 / 2 = 511 R 1

511 / 2 = 255 R 1

255 / 2 = 127 R 1

127 / 2 = 63 R 1

63 / 2 = 31 R 1

31 / 2 = 15 R 1

15 / 2 = 7 R 1

7 / 2 = 3 R 1

3 / 2 = 1 R 1

1 / 2 = 0 R 1

Hence;

[tex]1023_{10} = 1111111111_2[/tex]

Solving (c)

100632 / 2 = 50316 R 0

50316 / 2 = 25158 R 0

25158 / 2 = 12579 R 0

12579 / 2 = 6289 R 1

6289 / 2 = 3144 R 1

3144 / 2 = 1572 R 0

1572 / 2 = 786 R 0

786 / 2 = 393 R 0

393 / 2 = 196 R 1

196 / 2 = 98 R 0

98 / 2 = 49 R 0

49 / 2 = 24 R 1

24 / 2 = 12 R 0

12 / 2 = 6 R 0

6 / 2 = 3 R 0

3 / 2 = 1 R 1

1 / 2 = 0 R 1

Hence;

[tex]100632_{10} = 11000100100011000_{2}[/tex]

Triangle ABC is a right triangle.

Opposite side of the right angle B = Hypotenuse (AC)

and the other two legs are AB and BC

Pythagoras Theorem states

(hypotenuse)² = (leg 1)² + (leg 2)²

AC² = AB² + BC²

AC² = (6)² + (8)²

AC² = 36 + 64

AC² = 100

AC = √100

AC = 10

Therefore, length of the hypotenuse (AC) = 10 units will be the answer.

Step-by-step explanation:

Given the equation of a plane in rectangular coordinates to be y = 4x.

The cylindrical coordinates of the axis is as given below;

x = rcosθ

y = rsinθ

z = z

Since there is no z coordinate in the equation of the plane given, we will only substitute x = rcosθ and y = rsinθ into the equation y = 4x and simply the result as shown;

y = 4x

rsinθ = 4( rcosθ)

rsinθ = 4rcosθ

sinθ = 4cosθ

sinθ - 4cosθ = 0

Hence the equation for the plane in cylindrical coordinate is expressed as sinθ - 4cosθ = 0

The equation of the plane y=4x in cylindrical coordinates is,  [tex]sin\theta-4cos\theta=0[/tex]

To find the equation of plane in cylindrical coordinates,
