Answer:

9 years

Step-by-step explanation:

The simple interest formula is ...

I = Prt

where I is the interest earned on principal P invested at annual rate r for t years. Solving for t, we have ...

t = I/(Pr) = 1125/(2500×.05) = 1125/125

t = 9 . . . . years

It will take 9 years for Anna to earn 1125 in interest.

Hey there!

We want to multiply a certain quantity by 2, so we will put the two outside of parentheses and put our variable (x) minus two inside the parentheses to represent this. This will all equal two.

2(x-6)=2

The unknown number is also 7.

I hope that this helps!

Answer:

first option

Step-by-step explanation:

To obtain ( f ￮ g)(x) substitute x = g(x) into f(x) , that is

f( $\frac{1}{2x}$ )

= $\frac{2}{\frac{1}{2x}+3 }$ ( multiply numerator/ denominator by 2x to clear the fraction

= $\frac{2(2x)}{2x(\frac{1}{2x}+3) }$

= $\frac{4x}{1+6x}$

What is the volume in cubic centimeters of a right circular cone with radius 2 centimeters and height 9 centimeters?

andreev551 [17]

Answer:

$V = 37.7cm^3$

Step-by-step explanation:

The formula for the volume of a cone is:

$V = \frac{1}{3} \pi r^2h$

Given:

- Radius = 2cm

- Height = 9cm

Let's plug these into the equation:

$V = \frac{1}{3} \pi (2)^2(9)$

Now solve:

$V = \frac{1}{3} \pi (4)(9)\\V = \frac{1}{3}\pi 36\\V = \frac{36}{3} \pi \\V = 12\pi \\V = 37.7cm^3$

Therefore, the volume of the cone is 37.7cm^3.

I hope this helps!!
