Step-by-step explanation:

You are adding, when you add it up you get 24 which isnt convertable to exponents. Exponenets multiply out such as 4*4*4*4*4*4

Answer:

12

Step-by-step explanation:

12 is the area

Since,

6×2=12

Answer:

No

Step-by-step explanation:

1 is a prime number

0 is the only number that is neither prime or composite

Hello there!

No, 1 is not the only number that is neither prime nor composite.

0 is neither prime not composite because it has infinite factors. Composite numbers have more than 2 factors, but they must have a finite amount o factors. Since 0 has infinite factors, then it's neither prime nor composite.

Hope it helps!

Answer:

x = 12.936

Step-by-step explanation:

sin(38) = .616

x/21 = .616/1

x = 12.936

Answer: x= 12.92889098

Step-by-step explanation:

Step 1: Cross multiply sin38/1 with x/21  

Step 2: x= 21 sin38

step 3: use a scientific calculator (you can type in desmos calculator for one) to input 21 sin(38) to get answer.

Answer:

15

Step-by-step explanation:

75.00 - 20% is 60

60 + (tax 15) is 75.00

So I'm guessing that the tax rate is 15

20

Step-by-step explanation:

5/ 1/4 --> 5 x 4 (flip the 1 and 4 in 1/4)

Answer:

Option C is the correct answer.

Step-by-step explanation:

Per week earning = $8

Amount in savings = $12

y = Total amount

x = Number of weeks

y = 8x + 12

Where we can put x=4 to calculate earning of 4 weeks.

y = 8(4) + 12

y = 32 + 12 = $44

Therefore,

Option C is the correct answer.

Answer:

Correct Answer is B. The first equation in B is the sum of the equations in A, while the other is obtained  by multiplying the first equation in A by 2.

Step-by-step explanation:

As given,

A : 6x + 8y = -10     .......equation (1)

     2x - 5y = 12      .......equation (2)

B : 8x + 3y = 2         .......equation (1)

  12x + 16y = - 20    .......equation (1)

Correct Answer is B. The first equation in B is the sum of the equations in A, while the other is obtained  by multiplying the first equation in A by 2.

Proof :

The first part says that ,

Sum of equation (1) of A and equation (2) of A = Equation (1) of B

Firstly , find the Sum of equation (1) of A and equation (2) of A

⇒6x + 8y + 2x - 5y = -10 + 12

⇒8x + 3y = 2

this is same as equation (1) of B

So, it satisfies the first part

The second part says that,

The equation (2) of B is obtained by multiplying the first equation in A by 2.

It means , if the equation (1) is multiplied by 2 = equation (2) of B

Firstly , if the equation (1) is multiplied by 2 , we get

2 ( 6x + 8y = -10 )

⇒ 2 ( 6x + 8y ) = 2 ( -10)

⇒ 12x + 16y = -20

this is same as equation (2) of B

So, it satisfies the second part.

Answer:

3 miles

Step-by-step explanation:

Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles

This is the change in miles / change in time.

Chang in miles = 3

Change in time = 1

Slope = 3/1

Slope = 3

Answer:

Team blue points = 4 points

Team green points = 16 points

Step-by-step explanation:

Let

Team blue points = x

Team green points = (x + 12) points (1)

Team green points = 4x (2)

Equate equation (1) and (2)

x + 12 = 4x

12 = 4x - x

12 = 3x

x = 12/3

x = 4 points

Team blue points = x

= 4 points

Team green points = (x + 12)

= 4 + 12

= 16 points

Team green points = 4x

= 4(4)

= 16 points

Answer: 2x and y= 4+

Answer:

The rate of change of the height is approximately [tex]-6.577\times 10^{-3}\,\frac{in}{min}[/tex].

Step-by-step explanation:

From Geometry we know that volume of cylinder ([tex]V[/tex]), measured in cubic inches, is expressed by:

[tex]V = \pi\cdot r^{2}\cdot h[/tex] (1)

Where:

[tex]r[/tex] - Radius, measured in inches.

[tex]h[/tex] - Height, measured in inches.

Given that volume remains constant, the expression for the rate of change of the height ([tex]\dot h[/tex]), measured in inches per minute, is:

[tex]2\pi\cdot r \cdot h \cdot \dot r + \pi \cdot r^{2}\cdot \dot h = 0[/tex]

[tex]2\cdot h\cdot \dot r + r\cdot \dot h = 0[/tex]

[tex]r\cdot \dot h = -2\cdot h \cdot \dot r[/tex]

[tex]\dot h = -\frac{2\cdot h\cdot \dot r}{r}[/tex]

[tex]\dot h = - \left(\frac{2\cdot \dot r}{r}\right)\cdot \left(\frac{V}{\pi\cdot r^{2}} \right)[/tex]

[tex]\dot h = -\frac{2\cdot \dot r \cdot V}{\pi\cdot r^{3}}[/tex] (2)

Where [tex]\dot r[/tex] is the rate of change of the radius, measured in inches per minute.

If we know that [tex]r = 44\,in[/tex], [tex]\dot r = 2\,\frac{in}{min}[/tex] and [tex]V = 440\,in^{3}[/tex], then the rate of change of the height is:

[tex]\dot h = - \frac{2\cdot \left(2\,\frac{in}{min} \right)\cdot \left(440\,in^{3}\right)}{\pi\cdot (44\,in)^{3}}[/tex]

[tex]\dot h \approx -6.577\times 10^{-3}\,\frac{in}{min}[/tex]

The rate of change of the height is approximately [tex]-6.577\times 10^{-3}\,\frac{in}{min}[/tex].

Answer:

Its reflected over the y axis

Answer:

z= 2√2

x=2

y=2√2

Answer: Below is the first one

Step-by-step explanation: Second one is right here x=1/5+y/5

(Pi value = 3)

Given diameter of circle = 12 inches

Radius of circle :

[tex] = \tt\frac{diameter}{2} [/tex]

[tex] = \tt\frac{12}{2} [/tex]

[tex] = \tt6 \: inches[/tex]

Thus, the radius of this circle = 6 inches

Circumference of this circle :

[tex] = \tt2\pi r[/tex]

[tex] =\tt 2 \times 3 \times 6[/tex]

[tex] = \tt36 \: inches[/tex]

Thus, the circumference of this circle = 36 inches

The area of this circle :

[tex] = \tt\pi {r}^{2} [/tex]

[tex] =\tt 3 \times 6 \times 6[/tex]

[tex] = \tt108 \: {inches}^{2} [/tex]

Thus, the area of this circle = 108 inches²
