sue stacked one box onto another. the bottom had the height of 2 1/3 feet and the top box had the height of 3 2/3 feet. how tall

Scilla [17]

Height of bottom box : - $2 \frac{1}{3} => 7/3$
Height of top box : - $3 \frac{2}{3} => 11/3$

Thus, height of two boxes =

$\frac{7}{3} + \frac{11}{3} = \frac{18}{3} => 6ft$

0.27 recurring as a fraction please

natali 33 [55]

Answer:

$\frac{3}{11}$

Step-by-step explanation:

assuming the recurring digits are 0.272727.... , then

we require 2 equations with the repeating digits placed after the decimal point.

let x = 0.2727.... (1) ← multiply both sides by 100

100x = 27.2727... (2)

subtract (1) from (2) thus eliminating the repeating digits

99x = 27 ( divide both sides by 99 )

x = $\frac{27}{99}$ = $\frac{3}{11}$ ← in simplest form

A rectangular poster has an area of 190 inches squared. The height of the poster is one inch less than twice its width. Find the

Annette [7]

Set the height to h, and the width to w.

We know that wh=190 and h=2w-1.

Substituting 2w-1 for h, we have:

w(2w-1)=190

So:
2w^2-w-190=0

Factoring this equation, we get (2w+19)(w-10)=0. The solutions to this equation are -9.5 and 10, but clearly the width must be positive, Substituting 10 for the width, we get 10*2-1=19 for the height.
