Answer:

2.1

Step-by-step explanation:

1 x 0.2 = 0.2

1.2 x 0.2 = 0.24

1.44 x 0.2 = 0.288

1.728 x 0.2 = .3456

1.728 + 0.3456 = about 2

Answer:

To find the sum of interior angles in a polygon, we can use the formula:

$180(n-2)$ where n is the number of sides.

Since this is pentagon (5 sides), then $180(5-2)=180*3=540$

The missing angle would then be

$540-97-111-104-115=113$

Since angles on a straight line add up to 180, then

$x+113=180$

$x=67$

Fill in the blanks 864+2006=--------+864 5351 +(574+799)= 574+(5351+_____)

Mama L [17]

Answer:

2006

799

Step-by-step explanation:

Given the expression:

The right hand side of the sun must be equal to the left hand side ;

Therefore ;

864+2006=--------+864

The sum of 864 and 2006 must be equal to the right hand side sum ; hence

864+2006= 2006 +864

Similarly, the left hand side and right havd side must also be equal here ;

5351 + 574 + 799 = 574 + 5351 + 799

Hence, the missing value is 799

HELP DUE IN 15 MINS!

Answer:

r = $2\sqrt{5}$

$(x - 3)^{2} + ( y - 2)^{2} = 20$

Is this a live test question or a homework question?

Step-by-step explanation:

the radius is the distance between (3, 2) and (5, -2)

$r^{2}$ = ${(3 - 5)^{2} + (2 + 2)^{2} }$

= $(-2)^{2} + 4^{2}$

= 4 + 16 = 20

r = $\sqrt{20 } = 2\sqrt{5}$

Equation of circle: $(x - 3)^{2} + ( y - 2)^{2} = 20$
