gregori [183]
Sure.
The rule says that "The 'n'th term is  2^n + 1. "

You're asked to find the 5th term, so plug '5' into the rule in place of 'n'.

The 5th term = 2^5 + 1

2^5 = 2 x 2 x 2 x 2 x 2 = 32

The 5th term = 32 + 1 = <em>33</em> .

Amiraneli [1.4K]
<span>1.       </span><span>Fiona drives 60 miles per hour on the Highway
And drives 30 miles per hour on the City.
She got a total of 312 hours in the highway and 112 hours in the city
Find the average speed of Fiona:
Formula of Speed
=> S = d / t
Let H be the distance in Highways
and Let C be the distance in City
=> H = 60 x 312
=> H = 18 720
=> C = 30 x 112
=> C = 3360
=> Total distance = 18 720 + 3 360
=> 22 080 miles
Let’s find the total time
=> H + C
=> 312 + 112
=> 424 hours

Speed = 22 080 / 424
S = 52.1 miles per hour

Solnce55 [7]

Answer :

(1) \frac{1}{x}+\frac{1}{y}=\frac{y+x}{xy}

(2) \frac{1}{5x}+\frac{1}{3y}=\frac{3y+5x}{15xy}

(3) \frac{1}{7x}-\frac{1}{2y}=\frac{2y-7x}{14xy}

(4) \frac{2}{5x}+\frac{3}{7y}=\frac{6y+15x}{21xy}

(5) \frac{7}{11x}-\frac{1}{33y}=\frac{231y-11x}{363xy}

(6) \frac{1}{2x}+\frac{3}{x}-\frac{1}{7y}=\frac{7y+42y-2x}{14xy}

Step-by-step explanation :

(1) The given expression is: \frac{1}{x}+\frac{1}{y}

\frac{1}{x}+\frac{1}{y}=\frac{y+x}{xy}

(2) The given expression is: \frac{1}{5x}+\frac{1}{3y}

\frac{1}{5x}+\frac{1}{3y}=\frac{3y+5x}{(5x)\times (3y)}=\frac{3y+5x}{15xy}

(3) The given expression is: \frac{1}{7x}-\frac{1}{2y}

\frac{1}{7x}-\frac{1}{2y}=\frac{2y-7x}{(7x)\times (2y)}=\frac{2y-7x}{14xy}

(4) The given expression is: \frac{2}{5x}+\frac{3}{7y}

\frac{2}{5x}+\frac{3}{7y}=\frac{(2\times 3y)+(3\times 5x)}{(5x)\times (7y)}=\frac{6y+15x}{21xy}

(5) The given expression is: \frac{7}{11x}-\frac{1}{33y}

\frac{7}{11x}-\frac{1}{33y}=\frac{(7\times 33y)-(1\times 11x)}{(11x)\times (33y)}=\frac{231y-11x}{363xy}

(6) The given expression is: \frac{1}{2x}+\frac{3}{x}-\frac{1}{7y}

\frac{1}{2x}+\frac{3}{x}-\frac{1}{7y}=\frac{(x\times 7y)+(3\times 2x\times 7y)-(2x\times x)}{(2x)\times (x)\times (7y)}=\frac{7xy+42xy-2x^2}{14x^2y}=\frac{7y+42y-2x}{14xy}
