What is the answer for number 1?
Flura [38]

Answer:

28.26

Step-by-step explanation:

A = pie x radius*2

The radius is 3, and pie is 3.14. This means the equation is

A = 3.14 x 3*2

3*2 is just 3 x 3, which is 9.

9 x 3.14 = 28.26

Solve for x.<br> 2.8 3.2x + 1 = 16.6
Yuliya22 [10]

Answer:

\sf x = \dfrac{15.6-2.8a}{3.2}

Step-by-step explanation:

Solve for 'x'.

To solve for 'x', isolate 'x'.

 2.8a + 3.2x + 1 = 16.6

Subtract 1 from both sides.  {Subtraction property of equality}

   2.8a + 3.2x = 16.6 - 1

    2.8a + 3.2x = 15.6

Subtract 2.8 a from both sides.

              3.2x  = 15.6 - 2.8a

Now, divide both sides by 3.2.  {Division property of equality}

                 \sf \dfrac{3.2x}{3.2}=\dfrac{15.6-2.8a}{3.2}\\\\\boxed{x=\dfrac{15.6-2.8a}{3.2}}

What is the ratio of the area of the inner square to the area of the outer square?
mars1129 [50]
The answer is
<span>(a−b)²+b²/a²


proof

if A is the area of the
</span><span>inner</span> squared, so A= c², and c²= (a−b)²+b²

so the side of the outer must be a-b +b=a, its area is a²

ANSWER ASAP PLEASE
ruslelena [56]

Answer:

jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct

Step-by-step explanation:

so, all angles of a triangle have to add up to 180;

(15x) + (8x - 11) + (3x + 9) = 180

15x + 8x - 11 + 3x + 9 = 180

add your common numbers

26x - 2 = 180

add 2

26x = 182

divide 26

x = 7

put it back into the equation

15(7) + 8(7) - 11 + 3(7) + 9 = 180

180 = 180
