Answer:

∴At the beginning of the game Sparrow had = (70+12)=82 coins

Step-by-step explanation:

Given , three pirates named Ahab, Sparrow and Davy play a game.

Let at the end of the game Ahab, Sparrow and Davy have 4x, 5x,and 6x coins respectively.

Total number of coins= 4x+5x+6x=15x

Again given that the pirates have a total of 210 coins.

According to the problem,

15x =210

⇔x = 14

Therefore, Ahab, Sparrow and Davy have(4×14)=56,(5×14)=70 and (6×14)=84 respectively.

Since,Ahab has won 5 coins and Davy has won 7 coins.This(7+5)=12 coins was belonged to Sparrow.

∴At the beginning of the game Sparrow had = (70+12)=82 coins

What are the zeros of the polynomial function f(x) = x3 + x2 − 20x?

Irina-Kira [14]

$x^3 + x^2 - 20x=0\\
x(x^2+x-20)=0\\
x(x^2+5x-4x-20)=0\\
x(x(x+5)-4(x+5))=0\\
x(x-4)(x+5)=0\\
x=0 \vee x=4 \vee x=-5$

The City Sights tour company had the same ratio of tourists to guide on both days this weekend.On Saturday,there were 120 touris

vivado [14]

Answer: There were 6 guides on Sunday.

Step-by-step explanation:

I suppose that this is a question about equivalent ratios:

It is said that the company had the same ratio of tourists to guides on Saturday and Sunday.

RATIO OF TOURISTS TO GUIDES:

SATURDAY: 120 : 18

SUNDAY: 40 : ?

Divide 120 by 40:

120/40 = 3

Divide 18 by 3:

18/3 = 6

Therefore:

SAT: 120 : 18

SUN: 40 : 6

Check it by multiplying both numbers in the ratio 40 : 6 by 3:

40 • 3 : 6 • 3

= 120 : 18

(You get the ratio from Saturday)

Hope this helps!
