I got 180 because (although the picture is smaller and digital meaning I may be off) angle AOD = 85 degrees while angle BOC = 95. 95 + 85 = 180.

The triangle formed by radii to the ends of a chord of a circle is an isosceles triangle. That means the central angle will be 180° less twice the base angle shown.
.. ∠AOB = 180° -2*35° = 110°
.. ∠COD = 180° -2*55° = 70°

Then the desired sum is
.. ∠AOD +∠BOC = 360° -110° -70° = 180° . . . . . . corresponds to selection A

9. A 3D printer uses one spool of filament to produce 20 congruent solids. Suppose you want to produce similar solids that are 1
Evgesh-ka [11]

Answer:

15 figures

Step-by-step explanation:

To know with this, and knowing that each dimension is 10% longer, let's do a simple example assuming some random values.

Let's suppose that you have cylinder with a radius of 3 cm and height of 5 cm. The volume of this cylinder is:

V = π*(3)^2*5 = 45π cm^3

Now, if we raise the dimensions by 10%, the radius and height will be 3.3 and 5.5 respectively so, the new volume (V2) will be:

V2 = π*(3.3)^2*5.5 = 59.9π cm^3

So the ratio of both volumes is:

59.9π/45π = 1.331

This means that each new solid would have 1.331 times the volume of the original solid. Therefore, we can stablish a relation between the original figures and the new ones calling "x" the number of new figures so:

20 = 1.331x

solving for x:

x = 20/1.331

x = 15.03

You can round this to 15.

The difference of two numbers is 30. their quotient is 6. what are the two numbers
BlackZzzverrR [31]
Well, the quotient must be bigger/smaller

lets say the numbers are x and y
x>y

so
x-y=30 and x/y=6
multiply both sides by y in 2nd equation
x=6y
subsitute 6y for x in other equation

6y-y=30
5y=30
divide by 5
y=6

sub back
x=6y
x=6(6)
x=36


the numbers are 36 and 6

but they could also be -36 and -6 because -36/-6=6 and -6-(-36)=30


the 2 numbers are 36 and 6 or -36 and -6

How do you solve 0.8=6-2.5x
photoshop1234 [79]
X=2.08

To solve you need to first get x by itself. To do that you want to subtract 6 from both sides (get 6 away from x and put on other side) which will leave you with -5.2=-2.5x next isolate x by dividing -2.5 on both sides to then get 2.08=x
