Answer:

7.722cm^2, x=129

Step-by-step explanation:

12*12=144- area of the whole square

the diameter for the circle is 12

radius is 6

Area for circle= pi* r²

3.142*6^2=113.112

144-113.112=30.888

30.888/4=7.722

Answer:

it looks like the answer to this problem is $280.

Step-by-step explanation:

i got this answer because you add $100 and $250 together. You will get $350. Then you take 20% of that total. So, 20% of 350 is 70. Now take 350-70, which = 280. and that should be your final answer.

Answer:

3052.08 m³

Step-by-step explanation:

[tex]\boxed{volume \: of \: sphere = \frac{4}{3}\pi {r}^{3} }[/tex]

Given that the radius is 9m, r=9.

Volume of sphere

[tex] = \frac{4}{3} (3.14)(9^{3} )[/tex]

= 3052.08 m³

Answer:

Volume = 4/3 • π • r³

Volume = 4/3 • 3.14 • (9)³

Volume = 4/3 • 3.14 • 9 • 9 • 9

Volume = 4 • 3.14 • 27 • 9

Volume = 3052.08 cm³

I think the answer is D, 15 Square Inches

Given:

The length of your family's garden is 3 feet greater than the width.

The area of the garden is 460 square feet.

To find:

The dimensions of the garden.

Solution:

Let x feet be the width of the garden. Then,

Length = [tex]x+3[/tex] feet

The area of a rectangle is:

[tex]A=l\times w[/tex]

Where, l is the length and w is the width of the rectangle.

The area of the rectangular garden is:

[tex]A=(x+3)\times x[/tex]

[tex]A=x^2+3x[/tex]

It is given that the area of the garden is 460 square feet.

Putting [tex]A=460[/tex], we get

[tex]460=x^2+3x[/tex]

[tex]0=x^2+3x-460[/tex]

Splitting the middle term, we get

[tex]x^2+23x-20x-460=0[/tex]

[tex]x(x+23)-20(x+23)=0[/tex]

[tex](x+23)(x-20)=0[/tex]

[tex]x=-23,20[/tex]

The width of a garden cannot be negative. So, [tex]x=20[/tex].

Now,

[tex]l=x+3[/tex]

[tex]l=20+3[/tex]

[tex]l=23[/tex]

Therefore, the length of the garden is 23 feet and the width of the garden is 20 feet.

Step-by-step explanation:

Given

[tex]y = 0.554x - 0.507[/tex]

The question is incomplete; however, a possible question could be to interpret the given equation.

The equation is given in slope intercept form i.e. [tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

[tex]b = y\ intercept[/tex]

So, by comparing:

[tex]y = mx + b[/tex] to [tex]y = 0.554x - 0.507[/tex]

[tex]m = 0.554[/tex]

[tex]b = -0.507[/tex]

Hence, the slope of the regression is 0.554 and the y intercept of -0.507

Answer:

B. (13 - 6)n - 40

Step-by-step explanation:

If each bottle costs them $6 and they are selling each one for $13, the amount of money they make for each bottle can be represented by (13 - 6)n

This is because this finds the profit per bottle, then multiplies it by n, which is the number of bottles they sell.

Then, since they spent $40 on advertising, subtract 40 from this.

The expression will be (13 - 6)n - 40.

The correct answer is B. (13 - 6)n - 40

The expression represents the money that the group raises is  (13-6)n  - 40

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

According to the question

Members of a school sports team are raising money by selling custom water bottles at school activities.

Let number of bottle they sell = n

Selling price of a bottle = $13

Now ,

Selling price of n bottle =  $13n

Cost price of a bottle =  $6

Now ,

Cost price  of n bottle =  $6n

Money spent on advertising = $40

Total they spent on bottles = $6n +  $40

Therefore,

Money they raise in expression =  13n - 6n - 40

                                                      =  (13-6)n  - 40

Hence, The expression represents the money that the group raises is  (13-6)n  - 40
