The jar problem

Step-by-step explanation:

Joaana saves nickels and quarter in a jar

She looked to see if she had enough coins to fix her car

She didn't so she went on the side of the street to play her guitar

She played for money by a food bar

She worried she wouldn't make a lot

So she bet illegally on some chickens that fought

She was scared the cops would come and she would get caught

The saw the cops coming and her eyes lit up like a match

She grabbed $500 and she was one they wouldn't catch

It turns out she only needed $10 to fix a tiny scratch

She only had $5 is coins in her jar

Now she has $500 and can fix her car

Hope this helps ya! Keep smiling!

-8x-2y<6

-8(3)-2(2)<6

-24-4<6

-20<6

Answer:

-8x – 2y < 6

-8(3) - 2(2) < 6

-24 - 4 < 6

-28 < 6

True

Step-by-step explanation:

Answer:

4(6 + 5)

Step-by-step explanation:

Given summation:

             24 + 20

The greatest common factor:

  Factors of:

                   24  = 1, 2, 3, 4, 6, 8, 12 and 24

                   20 = 1, 2, 4, 5, 10 and 20

the gcf  = 4;

     24 + 20  = 4(6 + 5)

This shows the gcf and distributive property

Answer:

So, the distance covered by man if he takes 3 rounds is 3491.16 inches

Step-by-step explanation:

We are given area of square field i.e 84642 and we need to find distance covered by man if he takes 3 rounds of the field.

Distance covered by man = Perimeter of square field

First we have to find length of side of square field.

The formula used is Area of square= (Length)^2

Putting value of area and finding length.

[tex]Area of square= (Length)^2\\\sqrt{Length} =\sqrt{84642} \\Length= 290.93\\[/tex]

So, length of square field is 290.93 inches

Now finding the distance covered by man if he takes 3 rounds

First find perimeter

Perimeter of square = 4*length

Perimeter of square = 4*290.93

Perimeter of square = 1163.72 inches

Distance covered by man if he takes 3 rounds = 3*Perimeter of square

Distance covered by man if he takes 3 rounds = 3*1163.72

So, the distance covered by man if he takes 3 rounds is 3491.16 inches

Answer:

(- 2x , - 2y)

Step-by-step explanation:

A(x, y) ----> A' (kx, ky)

~~~~~~~~

H(- 1 ,1) ----> [k(- 1), k(1)] ----> G(2, - 2) ⇒ k = - 2

M( - 1.5, - 4) -----> [(- 2)(- 1.5) , (- 2)(- 4)] ------> R(3. 8)

k = - 2

Thus, the rule of dilation centered in origin is (- 2x , - 2y)

Answer:

(a) 0.198 cm/s (b) 1 cm/s

Step-by-step explanation:

It is given that,

The rate of change of area of a cicle, [tex]\dfrac{dA}{dt}=5\ cm^2/s[/tex]

(a) The area of a circle is given by :

[tex]A=\pi r^2[/tex]

Differentiate both sides,

[tex]\dfrac{dA}{dt}=2\pi r\dfrac{dr}{dt}\\\\\text{Put the value of dA/dt and r = 4 cm}\\\\\dfrac{dr}{dt}=\dfrac{dA/dt}{2\pi r}\\\\\dfrac{dr}{dt}=\dfrac{5}{2\pi \times 4}\\\\\dfrac{dr}{dt}=0.198\ cm/s[/tex]

(b) Circumference, [tex]C=2\pi r[/tex] = 5 cm

[tex]\dfrac{dA}{dt}=2\pi r\dfrac{dr}{dt}\\\\\dfrac{dr}{dt}=\dfrac{dA/dt}{2\pi r}\\\\\dfrac{dr}{dt}=\dfrac{5}{5}\\\\\dfrac{dr}{dt}=1\ cm/s[/tex]

Hence,

(a) 0.198 cm/s (b) 1 cm/s

Answer:

hello your question is incomplete attached below is the complete question and solution

Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified line. Sketch the region, the solid, and a typical disk or washer.

y = x^2  ,  x = y^2   about  x = -1

answer : [tex]\frac{29\pi }{30}[/tex]

Step-by-step explanation:

given curves = y = x^2 and x = y^2

we determine the inner and outer radii using the washer method

inner radius = R2(y) = 1 + y^2

outer radius = R1 (y) = 1 + [tex]\sqrt{y}[/tex]

volume of the solid = [tex]\frac{29\pi }{30}[/tex]

attached below is a detailed solution and required sketch

Answer:

1/6

Step-by-step explanation:

Use conditional probability:

P(A given B) = P(A and B) / P(B)

P(4 given 3) = P(4 and 3) / P(3)

P(4 given 3) = (1/36) / (1/6)

P(4 given 3) = 1/6
