Answer:
The answer to your question is letter C
Step-by-step explanation:
This is a problem with the inverse rule of three because we expect that more machines can complete the same work in fewer days.
6 machines ------------------ 12 days
x machines ------------------- 8 days
x machines = 
x = 4 machines
If Bryan has three stamps and gets 2 new stamps every week how many stamps would he have in 3 weeks?
2x3+3=?
6+3=9
Bryan would have 9 stamps in 3 weeks.
Answer:
6 s^9 t^3
Step-by-step explanation:
When you multiply same variables with exponents, you want to add the expoenents.
6s^5t * s^4t^2
s^5 * s^4 = s^9
t * t^2 = t^3
6 * 1 = 6
6 s^9 t^3

Answer: C. 50</h3>
==============================================
Explanation:
The diagonal cuts the rhombus into two congruent isosceles triangles. We know they are isosceles because the non-diagonal sides are equal in length (since all four sides of a rhombus are the same length).
Let x be the measure of angle 1. This is one base angle. The other base angle is also x as well. The third angle of the bottom triangle is angle 3, which is given to us at 80 degrees. For any triangle the three angles always add to 180.
x+x+80 = 180
2x+80 = 180
2x = 180-80
2x = 100
x = 100/2
x = 50
Angle 1 is therefore 50 degrees.
Angle 2 is also 50 degrees because angles 1 and 2 are congruent alternate interior angles. Any rhombus is a parallelogram (but not the other way around) so the top and bottom lines of the rhombus are parallel, allowing the alternate interior angles to be congruent.
