tatyana61 [14]

Given

John had a roll containing of wrapping paper

$=24\tfrac{2}{3}$

First, he must cut off 5/6 foot because it was torn.

He wants to divide it into 11 pieces.

To proof

As given in question

John had a roll containing of wrapping paper

$=24\tfrac{2}{3}$

$=\frac{74}{3}$ ( solving the mixed fraction form)

First, though, he must cut off 5/6 foot

than we get

$= \frac{74}{3} - \frac{5}{6}$

Taking the L.C.M of 3 and 6 is 6

$=\frac{148-5}{6}$

$=\frac{143}{6}$

=23.83 feet (approx)

He wants to divide it into 11 piece

length of the each piece

$=\frac{23.83}{11}$

length of the each pieces be 2.16 feet ( approx)

Hence proved

Verdich [7]

Mike ($3.75): x

Friends ($3.75): 3x

Mike + Friends ≤ 25

3.75(x) + 3.75(3x) ≤ 25

3.75x + 11.25x ≤ 25

15x ≤ 25

$\frac{15x}{15}$ ≤ $\frac{25}{15}$

x ≤ 1 $\frac{2}{3}$

Answer: they can rent the paddleboards for 1 hour 40 minutes

Rewrite the given expression in the form 3^u where u is a constant or an algebraic expression.

lawyer [7]

Simplifying the given expressions we proceed as follows:
(5sqrt3)^x
=5^x*(3^1/2)^x
=5^x*3^x/2
=5^x3^u
where u=x/2

(1/2)^(x-3)
=1/2^(x-3)
=2^-(3-x)
=2^u
where u=-(3-x)

9/3sqrt(3)
=3/(3)^(1/2)
=3(3)^(-1/2)

16/(3sqrt (2^x))
=1/3*(2^4*2^(-x/2))
=1/3*2^(4-x/2)
=1/3*2^u
where:
u=4-x/2
