HELP!!! A cell phone is 132 mm long and 57 mm wide. What is ratio of the width and length in simplest form.

GalinKa [24]

The ratio of width to length in simplest form is 19 : 44

Solution:

Given that, A cell phone is 132 mm long and 57 mm wide

Length of cell phone = 132 mm

Width of cell phone = 57 mm

We have to find the ratio of width and length in simplest form

$\frac{Width}{Length} = \frac{57}{132}\\\\\text{Reduce to lowest terms }\\\\\frac{width}{length} = \frac{57 \div 3}{132 \div 3}\\\\\frac{Width}{Length} = \frac{19}{44}$

In ratio form, we know that,

$\frac{a}{b} = a : b$

Writing in ratio form, we get

Width : length = 19 : 44

Thus the ratio of width to length in simplest form is 19 : 44

What is the slope of (-2,-2) and (-4,1)

FinnZ [79.3K]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-2, -2) and (-4, 1). Substitute:

$m=\dfrac{1-(-2)}{-4-(-2)}=\dfrac{1+2}{-4+2}=\dfrac{3}{-2}=-\dfrac{3}{2}$

<h3>Answer: slope = $-\dfrac{3}{2}$ </h3>

M<KGH=x+161,m<FGK=x+41,and m<FGH=180° Find x

Butoxors [25]

Answer: x = -11 ∠FGK = 30° ∠KGH = 150°

Step-by-step explanation:

∠FGK + ∠KGH = ∠FGH Segment Addition Postulate

x + 41 + x + 161 = 180 Substitution

2x + 202 = 180 Simplify (added like terms)

2x = -22 Subtraction Property of Equality

x = -11 Division Property of Equality

∠FGK = x + 41 = (-11) + 41 = 30

∠KGH = x + 161 = (-11) + 161 = 150
