Answer:

$b+8$

Step-by-step explanation:

'Increased by' means addition. If b+8 is less than 28, 28 is bigger, and the relation opens towards the bigger number.

To solve, subtract 8 from both sides:

$b+8-8$

In circle D, if the measure of arc Gec is 230 , what is the measure of minor arc GFC

BabaBlast [244]

Answer:

The measure of minor arc GFC is $130\°$

Step-by-step explanation:

we know that

In a circle the sum of the major arc plus the minor arc is equal to 360 degrees

see the attached figure to better understand the problem

Let

x------> the major arc GEC

y-----> the minor arc GFC

$x+y=360\°$

we have

$x=230\°$

substitute in the equation and solve for y

$230\°+y=360\°$

$y=360\°-230\°=130\°$

If you need carpet that is 6 1/2 long and 5 3/4 wide how many square feet do you need for the carpet??

Orlov [11]

Find the area

A= l*w

A = (6 1/2) * (5 3/4)

6 1/2 = (2*6+1)/2 =13/2

5 3/4 = (4*5+3)/4 = 23/4

A = 13/2 * 23/4

Plaese help !!!<br> 5/7m=15

Darina [25.2K]

$\dfrac{5}{7}m = 15$

Multiply both sides by 7/5.

$\dfrac{7}{5} \times \dfrac{5}{7}m = \dfrac{7}{5} \times 15$

$\dfrac{35}{35} m = \dfrac{7 \times 15}{5}$

$\dfrac{35}{35} m = \dfrac{7 \times 3 \times 5}{5}$

$m = \dfrac{7 \times 3}{1}$

$m = 21$

Which is an equation of a circle with center (5, 0) that passes through the point (1, 1)

alex41 [277]

Equation of circle at center (h,k) is given by

$(x-h)^2+(y-k)^2=r^2$

Given that center is at (5,0) that means h=5 and k=0

plug both values into above formula

$(x-5)^2+(y-0)^2=r^2$

$(x-5)^2+y^2=r^2$ ...(i)

Given that circle passes through point (1,1) so it will satisfy above equation

$(1-5)^2+1^2=r^2$

$(-4)^2+1^2=r^2$

$16+1=r^2$

$17=r^2$

Now plug this value of r^2 into equation (i)

$(x-5)^2+y^2=17$

which best matches with choice C

Hence $(x-5)^2+y^2=17$ is the final answer.
