The cost of a compact disc before the sale tax is $13.45. The correct option is B.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the total cost of a compact disc, including a 6% sales tax, is $14.31.

The cost before the sale tax will be calculated as,

Cost = 14.31 x ( 1 - 0.06 )

Cost = 14.31 x 0.94

Cost = $13.45

Answer:

6 km/hr or 5 km/hr

Step-by-step explanation:

In the lake, she goes 15 km at x km/hr (named)

In the river, she goes 6 km at x-2 km/hr (current=2 km/hr)

So, the time in the lake -  the time in the river = 1 hour (given)

15/x - 6/x-2 = 1 --> x=6;x=5

The speed of the boat as the photographer paddles the lake if the river current is 2 km/h is 6 km/hr and this can be determined by forming the quadratic equation.

Given :

According to the given data, if the river current velocity is 2 km/hr then let the speed in the lake be x km/hr. So, the speed of the photographer in the river is (x - 2) km/hr

Therefore, the speed of the boat as she paddles the lake if the river current is 2 km/h is given by:

[tex]\dfrac{15}{x} - \dfrac{6}{x-2}=1[/tex]

Now, simplify the above expression.

[tex]15(x-2)-6(x)=x(x-2)[/tex]

[tex]15x-30-6x=x^2-2x[/tex]

[tex]x^2-11x+30=0[/tex]

Factorize the above equation.

[tex]x^2-6x-5x+30=0[/tex]

x(x - 6) - 5(x - 6) = 0

(x - 6)(x - 5) = 0

x = 6 or 5

Answer:

Initial value: $25; Rate of change: 48; Equation: y= 8x + 25

Step-by-step explanation:

The initial value would be the $25 due to the fact that that's how much money she made during training. After that, her money will go up by $8 for every hour she works for, which is why that's the rate of change.

The equation just restates all that, the rate of change is always represented by the mx in the equation (8 replaces the m), and 25 replaces the b, the start of the line, or on a graph, where the initial dot would be on the y-axis.

Hope this helped!

Answer:

22 1/4 feet

Step-by-step explanation:

you can sketch this problem to be a right triangle with a hypotenuse of 24 feet and one leg of 9 feet (17 - 8).

use Pythagorean Theorem to find the base side, which represents the distance between the posts

a² + 9² = 24²

a² + 81 = 576

a² = 576 - 81

a² = 495

a = [tex]\sqrt{495}[/tex]

a = [tex]\sqrt{9}[/tex] · [tex]\sqrt{55}[/tex]  =  3[tex]\sqrt{55}[/tex], which is approx 22.25

Answer:

about 22.25 feet

Step-by-step explanation:

You can think of it like a triangle, which you can see at the bottom

Then, use the pythagorean theorem, [tex]a^2 + b^2 = c^2[/tex].

you have a = 9 and c = 24, so

[tex]9^2 + b^2 = 24^2\\81 + b^2 = 576\\b^2 = 495\\b = \sqrt{495} = 3\sqrt{55} = about 22.25[/tex]

Answer:

c= 25, solutions: x = 3, x= -13

Step-by-step explanation:

(10/2) ^2 = 25

Answer:

Ethan and Isabella are 9 meters apart.

Step-by-step explanation:

1. We can solve this using the Pythagorean Theorem, a²+b²=c².

2. Mrs. Gretta is standing 12 meters in front of Ethan, so a=12.

3. Isabella is sitting to Ethan's right, but we don't know how far away, so b=x.

4. Mrs. Gretta is 15 meters from Isabella, so c=15.

5. Plugging these variables into the equation, we get 12²+x²=15² which equals 144+x²=225.

6. We can move 144 to the other side to get x²=81, then square the 81 to get x=9.

7. Therefore, the answer is 9. Ethan and Isabella are 9 meters apart.
