The straight line equals 180
The two angels have to equal 180

180-63=117

117-25=92

92 divided by 4 is 23

x=23

I hope this helped!

How does the value of the digit 2 in 2000 compare with the value of the digit 2 in 200

iragen [17]

Answer:

The value of 2 in 2000 is 10 times greater than the value of 2 in 200

Step-by-step explanation:

from the value of 2 in 200 to reach 2000, it takes 10 times as much because we're moving only one place (which is the thousand's digit).

Pls help me with this. i have finals tomorrow and i dont get this

Serhud [2]

Answer:

We're here to help! Let me take this slowly.

44. First, we have the x-coordinate of the vertex to be -b/2a which is 16. Plugging 16 in, we have y-coordinate to be 135.

Notice that it is y=(x-7)(x-1).

So, we can just plug in values for x and y. Once you've got a lot of points, you can connect the dots and see how you can graph it.

The axis of symmetry is the x-coordinate of the vertex, or x=16.

45. Do the same method as mentioned above. I personally think that using transformations are more confusing, but that's just opinion. The axis of symmetry is x=-(-4)/2(-1) = -2, so axis of symmetry is x=-2.

46. We have x=-4 or x = 1/2.

47. We have (y-7)(y-1) = 0 ==> y=7,y=1

48. We have w^2 = 9, so w = +/- 3

49. We have (p-10)(p-3)=0, so p=10, p=3

50. We have (3m+1)(m+3)=0, so m=-1/3, m=-3

The sum of the areas of two circles is 80 pie square meters. Find the length of a radius of each circle if one of them is twice

Svetach [21]

Answer:

The radius of the circles are $4\ m$ and $8\ m$

Step-by-step explanation:

Let

x-----> the radius of larger circle

y----> the radius of smaller circle

we know that

$\pi x^{2} +\pi y^{2}=80\pi$

$x^{2} +y^{2}=80$ -----> equation A

Remember that

$x=2y$ -----> equation B

substitute equation B in equation A and solve for y

$(2y)^{2} +y^{2}=80$

$4y^{2} +y^{2}=80$

$5y^{2}=80$

$y^{2}=16$

$y=4\ m$

Find the value of x

$x=2y$

$x=2(4)=8\ m$

therefore

The radius of the circles are $4\ m$ and $8\ m$
