Geometry. Very basic.

AveGali [126]

Answer:

A)10.25 cm ; B)5 square cm

Step-by-step explanation:

Formula:

p=(a+b+c) [p= perimeter ; a,b , and c are the side lengths.]

∴The perimeter of the triangle =(4+2.75+3.5) cm

=10.25 cm

Formula:

A = 1/2 . b .h [A=area ; b= base ; h= height]

∴The area of the triangle = (1/2 . 4 . 2.5) square cm [b=4 ; h=2.5]

=5 square cm

The diagram shows the diffrence between my home h and two towns

katrin2010 [14]

Answer:

from home to town A :

V = D/t = 10 / 20 = 0.5 mile per min

from home to town B :

V = D/t = 20/30 = (2/3) mile per min

From town A to town B :

V = D/t = (10+20)/ 50 = (3/5) mile per min

Plz help asap... Explain as much as possible to me plz

Solnce55 [7]

Answer:

see explanation

Step-by-step explanation:

Since the 2 figures are similar then the ratios of corresponding sides are equal, that is

$\frac{8}{x}$ = $\frac{18}{6}$ ( cross- multiply )

18x = 48 ( divide both sides by 18 )

x = $\frac{48}{18}$ = $\frac{8}{3}$ = 2 $\frac{2}{3}$

Similarly

$\frac{5}{y}$ = $\frac{18}{6}$ ( cross- multiply )

18y = 30 ( divide both sides by 18 )

y = $\frac{30}{18}$ = $\frac{5}{3}$ = 1 $\frac{2}{3}$

ΔEFG ~ ΔLMN. Find the similarity ratio of ΔEFG to ΔLMN.

Basile [38]

Answer:

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{FG}{MN}$ = $\frac{4}{2}$ = $\frac{2}{1}$

Thus the ratio of Δ EFG to Δ LMN = 2 : 1 → C
