Answer:
4 2/4
Step-by-step explanation:
3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4
Answer:
1/12 or 1 out of 12
Step-by-step explanation:
Landing on red with the spinner is a 1/4 chance and the chance of rolling a 5 or 6 is 1/3. Multiplying the two fractions gives us the final probability, which is 1 out of 12.
Refer to the attached diagram for help.
All radii of a circle are congruent.
Tangent segs LP and LQ are congruent. (Tangent segs drawn to a circle from the same point are congruent)
Because of this we can establish OPLQ as a kite.
OPLQ is a kite implies that OL bis. angle PLQ.
An angle bis. divides an angle into 2 congruent, parts, so angle OLP must be 30 degrees.
Since tangents form right angles with the radius, angle OPL is right.
Now we have a right triangle OPL with a 30-degree angle. The other angle must be 60 degrees because of the no-choice theorem. (180-(30+90)) = 60
We know that OP is 6 because it is a radius of circle O. How do we use that to find OL? Well, we <em>could</em> use trig, but you might recognize this as a special triangle!
The side opposite the 30 degree angle = x
The side opposite the right angle = 2x
So OL must be 12!
Answer:
50%
Step-by-step explanation:
First, find the difference between the two values
1.8-1.2=0.6
Then divide the original value by the difference
difference/original value
0.6/1.2=0.5
0.5*100=50
So, the amount of iron increased by 50%
Hope this helped! :)
