Answer:
Diagonal =26.11 units
Step-by-step explanation:
Answer:
Part 1) The radius is 6 in and the diameter is 12 in
Part 2) The area of the dinner plate is
Step-by-step explanation:
we know that
The circumference of a circle is equal to
Part 1) What are the
radius and diameter of the dinner plate?
we have
assume
substitute in the formula and solve for the radius r
Find the diameter
The diameter is two times the radius
so
Part 2) What is the area of the dinner plate
The area of a circle is equal to
we have
assume
substitute
Answer:
a. she cleans 2.5 rooms per hour
b. im not sure what the equation would be
c. the point (6,15) represents 15 rooms were cleaned in 6 hours
d.20
e.4
Step-by-step explanation:
The discriminant is-
b^2-4ac=64-64=0
as the discriminant is 0, one solution will be -b/2a = -1/2
But still, we can't say that it has only one solution due to the nature of quadratic equations(It's tendency to have two solutions).
But we can say that both solutions are coincident.
Hence it has two solutions.
