In order to play in chess tournaments at the Marshall Club, Malik pays a fee to become a member. In addition, he pays a set rate
Keith_Richards [23]

Answer:

p = 22.50 + 15t

Step-by-step explanation:

For Malik :

Membership fee = m

Rate per tournament = t

After 4 tournaments :

m + 4t = 85 - - - (1)

After 7 tournaments :

m + 7t = 130 - - - (2)

Subtract 2 from 1

4t - 7t = 85 - 130

-3t = - 45

t = 45 / 3

t = 15

Put, t = 15 in (1)

m + 4(15) = 85

m + 60 = 85

m = 85 - 60

m = 25

Massai pays 10% less membership fee than Malik

Hence, Massai's membership fee:

(100 - 10)% * 25

0.9 * 25 = $22.50

Total price, p, Massai will pay to compete in t tournaments ;

Total price = membership fee + (rate per tournament * number of tournaments)

p = 22.50 + 15t

The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of
Jet001 [13]

Answer:

900 cubic inches.

Step-by-step explanation:

<u>Given the following data </u>

Volume of right circular cone = 300in³

We know that the volume of a right circular cone is given by the formula;

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

Where;

  • V is the volume of right circular cone.
  • r is the radius of the base of the right circular cone.
  • h is the height of the right circular cone.

The volume of a right circular cylinder is given by the formula;

V = \pi r^{2}h

Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.

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

<em>Substituting into the equation, we have;</em>

V = 300 * 3

V = 900in³

<em>Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.</em>

What is the difference of the rational expressions below?<br> X+5/x^2-2/5x
Leviafan [203]

Answer:

\large\boxed{\dfrac{x+5}{x^2}-\dfrac{2}{5x}=\dfrac{3x+25}{5x^2}}

Step-by-step explanation:

\dfrac{x+5}{x^2}-\dfrac{2}{5x}=\dfrac{5(x+5)}{5x^2}-\dfrac{2x}{5x^2}\qquad\text{use the distributive property}\\\\=\dfrac{5x+25}{5x^2}-\dfrac{2x}{5x^2}=\dfrac{5x+25-2x}{5x^2}=\dfrac{3x+25}{5x^2}
