Answer:

ΔGHI and ΔDEF are similar by SSS criteria

Step-by-step explanation:

Consider triangle GHI and triangle DEF

In ΔGHI, GH = 2, HI =4 and GI = 3.5

In ΔDEF , DE =4, EF = 6 and DF = 7

GH/DE = 2/4 =1/2

HI/EF = 3/6 = 1/2

GI/DF = 3.5/7 = 1/2

The corresponding sides are in same ratio by SSS criteria

ΔGHI and ΔDEF are similar

Suppose that y varies inversely with x. Use the information to find k, and then choose the equation of variation. x = 1.2 when y

baherus [9]

Y = k/x where k is the constant of variation
y = 3 , x = 1.2 gives
3 = k/1.2
therefore
k = 3*1.2 = 3.6
and the required equation is

y = 3.6 / x

Please help!!!!!WILL MARK BRAINLIEST.<br>what is the lateral area of the cone?

Ratling [72]

Answer:

Therefore Lateral Area of Cone is 189.97 yd².

Step-by-step explanation:

Given:

Slant height = 12.1 yd

Diameter = 10 yd

∴ Radius = half of Diameter = 10 ÷ 2 = 5 yd

To Find:

Lateral Area of Cone = ?

Solution:

We know that,

$\textrm{Lateral Area of Cone} = \pi\times Radius\times \textrm{Slant height}$

Substituting the given values we get

$\textrm{Lateral Area of Cone}=3.14\times 5\times 12.1\\\\\textrm{Lateral Area of Cone}=189.97\ yd^{2}$

Therefore Lateral Area of Cone is 189.97 yd².
