The president of a certain University receives a salary that is three times the salary of one of the department heads the total
Furkat [3]

<u>Answer:</u>

$142500

<u>Step-by-step explanation:</u>

We are given that the resident of a certain University receives a salary that is three times the salary of one of the department heads.

Assuming x to be the salary of the department head, if the total of the two salaries is $190000, we are to find the salary of the president of the University.

We can write an equation in terms of x:

3x+x=190000

4x=190000

x=47500

Salary of the president of the University = 3(47500) = $142500

Jude says that the volume of a square pyramid with base edges of 9.7 in and a height of 9 in is equal to the volume of a cylinde
earnstyle [38]

Answer:

The correct option is;

Yes, his calculations are correct and the volumes for figures are equal

Step-by-step explanation:

The volume, V, of a square  (of side s) pyramid of height h = \frac{1}{3} \times s^2 \times h

Where:

s = 9.7 inches

h = 9 inches

We have;

V = \frac{1}{3} \times 9.7^2 \times 9 = \frac{1}{3} \times 94.09 \times 9 = \frac{1}{3} \times 846.81 = 282.27 \approx 282 \ in^3

The volume, V_c, of a cylinder of radius r = Base area × Height, h = (π×r²)×h

Where:

Base area = π×r²

r = Radius of the cylinder = 5.47 inches

h = Height of the cylinder = 3 inches

V_c = π × 5.47² × 3 = π × 29.9209 × 3 = π × 89.7627 = 281.998 ≈ 282 m³

Therefore, Jude is correct.

Factor x^3+3x^2+2x completely
Arisa [49]

Answer:

x^3 + 3x^2 + 2x = x(x^2 + 3x + 2)

= x(x^2 + x + 2x + 2)

= x(x(x+1) + 2(x+1))

=x(x+1)(x+2)

Hope this helps!
