B) converse of the alternate interior angles theorem
if the alternate interior angles are congruent, the lines are parallel
Answer:36/10 ➗ 9/100
Step-by-step explanation:
3.6 ➗ 0.09 the other way is to put the numbers in fractions
36/10 ➗ 9/100
<h3>Problem Solution</h3>
Assuming the spool is a cylinder and the circumference we're winding around is that of a circle with the given area, we can write the relation between circumference and area as
... C = 2√(πA)
10 times the circumference is then
... 10C = 20√(π·20 cm²) = 40√(5π) cm ≈ 159 cm
<h3>Formula Derivation</h3>
The usual formulas for circumference and area are
... C = 2πr
... A = πr²
If we multiply the area formula by π and take the square root, we get
... πA = (πr)²
... √(πA) = πr
Multiplying this by 2 gives circumference.
... C = 2√(πA) = 2πr
The cost is what a manufacturer spends for their goods and services. The price is what they charge and the markup is the amount they charge extra from their cost. The correct answer is A.
So, Anna has a markers, Ben has b markers and Cindy has c markers.
We know that a+b+c = m.
And we know also that a = 2b. (<span> twice as many markers as ben has</span>)
(Remember b is the number of Ben markers.)
The equation becomes:
2b+b+c=m.
Solving for c:
Cindy has (m-3b) markers.
