Step-by-step explanation:

Answer:

It has two numbers per turn. The first is 2 and stays the same the whole time. The second number starts as 5, but every time it hits that number, it increases by 1.

Step-by-step:

As we already know, two starts off the turn, so every number on this turn will increase by 2 (6+2=8.)

Now, for this one, we have five, so for this turn we'll increase it by that much (8+5=13).

However, this number won't stay at 5. Instead, it will increase by 1 every time we hit this turn. Let's continue one:

Turn Two = 13+2=15

Turn 5+1 = 6 = 15+6=21

Turn Two = 21+2=23

Turn 6+1 = 7 = 23+7=31

And from there, the pattern would/will continue!

Whats the area of a circle with a circumference of \blueD{50.24}50.24start color #11accd, 50, point, 24, end color #11accd units.

Answers

Answer:

[tex]A=200.96\ unit^2[/tex]

Step-by-step explanation:

Given that,

The circumference of the circle, C = 50.24 units

We need to find the area of the circle.

The formula for the circumference of the circle is given by :

[tex]C=2\pi r[/tex]

r is the radius of the circle

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{50.24}{2\times 3.14}\\\\r=8\ units[/tex]

The formula for the area of a circle is given by :

[tex]A=\pi r^2\\\\A=3.14\times 8^2\\A=200.96\ unit^2[/tex]

So, the area of the circle is equal to [tex]200.96\ unit^2[/tex].

We know that we need to make the equation fit for one week. So for Nic we make the equation: 150x+75y. X being the weeks and y being the packages sold. Asia's equation would be 1275x. Make x equal 1, for one week.

150+75y

1275

Then subtract the weekly cash from each other.

1275-150= 1125

Than divide by 75 to see how many packages.

1125/75= 15

15 packages are needed to be sold.

Step-by-step explanation:

To factor polynomials you have to use FOIL. Which stands for First, Outer, Inner, and Last. This means that you have to multiply the first numbers of each part by each other, the outer two between both parts, the inner two between both parts, and the last two of each part, respectively. Then, you would simplify. If you go and do this for each answer choice, the last one would be the only correct one.

Again, use the area of a circle formula

A=pi(radius)2
A= 3.14(11)2
A=380.133 ft2

The area covered by the water will be 7850 square feet. The correct option is C.

What is the area of the circle?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.

Given that each rotating sprinkler in the park can water a circular section of grass that has a radius of 50 feet.

The area of the circle will be calculated by the formula below,

A = πr²

A=3.14 x ( 50 )²

A=7850 square ft

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{2}{3}[/tex] , then

y = [tex]\frac{2}{3}[/tex] x + c ← is the partial equation

To find c substitute (3, - 4) into the partial equation

- 4 = 2 + c ⇒ c = - 4 - 2 = - 6

y = [tex]\frac{2}{3}[/tex] x - 6 ← in slope- intercept form

Multiply through by 3 to clear the fraction

3y = 2x - 18 ( subtract 2x from both sides )

- 2x + 3y = - 18 ( multiply through by - 1 )

2x - 3y = 18 ← in standard form → D
