Write 931 x 10-5 in standard notation.

Answer:

r = 11 units

Step-by-step explanation:

Given that,

The measure of Arc CD is 11x

The arc is making an angle of 180°.

We know that,

Length of the arc, [tex]l=r\theta[/tex]

Where

r is the radius of the circle

So,

[tex]r=\dfrac{l}{\theta}\\\\r=\dfrac{ 11\pi}{\pi}\\\\r=11[/tex]

So, the radius of the circle is equal to 11 units.

then i will answer it

Answer:

I think the answer is 12,4

So 12 on the x axis and 4 on the y axis

Well I can't be for sure but I know for a fact its not set IV it's not possible to make a triangle out of all right angles. Set II, well, that isn't right either. You can't make a triangle out of all obtuse angles. Like the right angle one, its not possible you can only use one obtuse or right angle in a triangle other wise it's not going to be a triangle. I'd say go try Set III since that would most likely make an equilateral triangle.

Answer:

you forgot the picture

Step-by-step explanation:

lets take

x+y=100 firstly.

then x=100-y equation (i)

Now,

x-y=10

Putting value of x from equation(i)

100-y-y=10

-2y=10-100

-2y=-90

therefore, y=45

Now,

putting value of y in equation(i)

we get

x=100-45

ie x=55

hence, x=55 & y=45

Answer:

The solution is (55, 45).

Step-by-step explanation:

Solve the system of linear equations

x + y = 100

x - y = 10

through elimination by addition / subtraction.

Combining these two equations temporarily eliminates y, leaving us with 2x = 110.  Then x = 55.

Substituting 55 for x in the first equation, we get:

55 + y = 100.  Subtracting 55 from both sides leaves us with y = 45.

The solution is (55, 45).

Answer: 555

Answer:

64 c^2

Step-by-step explanation:

If the base is 8c and the height is 8c

A = bh

   = (8c) * (8c)

    = 84 c^2

Answer:

either 3 or zero if a unit is 0.5

but if a unit is 1, then it might be 4.5 and -1.5

Answer:

y=1/6x-2

Step-by-step explanation:

Parralel lines have the same slope.

Since the slope of the parralel equation has to be 1/6, and the point is (12,0)

then you input 12 for x and get 2.  But you need to get 0 for y, so the intercept would be negative 2.

Answer:

-2 = [tex]\frac{m}{16}[/tex] or [tex]\frac{m}{16}[/tex] = -2

Step-by-step explanation:

Diameter of BMX bike= 0.45m

Radius= 0.225m

Cirumference of BMX bike

C= 2πr

C=2*3.142*0.225

C= 1.4139m

In a 400-m race, the BMX bike will turn

=400/1.4139

=282.9 times

=283 times

Diameter of  Mountain bike= 0.6m

Radius= 0.3m

Circumference of Mountain bike

C= 2πr

C=2*3.142*0.3

C=1.8852m

In a 400-m race, the Mountain bike will turn

=400/1.8852

=212.17 times

=212 times

Hence the difference is

=283 -212

=71 times

Answer:

2(3x+,1)+2x=8x+1

=6x+2+2x=8x+1

=8x+2=8x+1

=2-1=8x-8x

=1=x

So x=1

Answer:

it should be x=-1 since 0= -1

Step-by-step explanation:

2(3x+1)+2x=8x+1

6x+2+2x=8x+1

8x+2=8x+1

8x+2-2=8x+1-2

8x=8x-1

8x-8x=8x-1-8x

0= -1
