The constant of proportionality (r) appears to be 3.
y = 3x . . . . . . . x = number of tickets sold; y = dollars collected
Answer:
A.
Step-by-step explanation:
We use the simple interest equation of A=P(1+rt).
A-the total amount with interest earned
P-the initial amount or principal
r-rate
t-time in years
We substitute the values P=300, A=381, and t=9. We then solve for r.
We divide both sides by 300.
Simplify.
We subtract 1 from both sides.
Simplify.
We divide by 9.
r=0.03
We need to convert the decimal to a percentage by multiplying by 100.
The interest rate is 3%.
Answer:
A. Transverse.
Step-by-step explanation:
We have been given a statement and we are supposed to choose the correct option to fill in the blank for our given statement.
Statement: The line segment that connects the two vertices of a hyperbola is called the ____ axis.
Since we know that the endpoints of transverse axis are known as the vertices of hyperbola, so the line segment that connects the two vertices of a hyperbola is called the <u>transverse </u> axis.
Therefore, option A is the correct choice.
It helps because seeing a number broken up helps your brain undertsand more clearly as to what exactly you are multiplying.
Four ninths means 4/9 and of means multiply= 4/9 × 45
=20/1
=20
