Write an informal proof to show triangles ABC and DEF are similar. Please don’t answer if you don’t know!!
Mila [183]

Answer:

ΔABC ~ ΔDEF

Step-by-step explanation:

If the given triangles ΔABC and ΔDEF are similar,

Their corresponding sides will be proportional.

\frac{\text{AB}}{\text{DE}}=\frac{\text{BC}}{\text{EF}}=\frac{\text{AC}}{\text{DF}}

By substituting the measures of the given sides,

\frac{4}{2}=\frac{6}{3}=\frac{2}{1}

2 = 2 = 2

Since, corresponding sides of both the triangles are proportional, both the triangles will be similar.

ΔABC ~ ΔDEF

UGH GEEZ PLEASE HELP
trapecia [35]

Answer:

$0.40

Step-by-step explanation:

1st week total: 12.99 + 10.50 + 9.89 + 6.90 + 7.58 = $47.86

5 days total so the mean of 1st week: 47.86 / 5 = $9.57

2nd week, 2 more in total of 1st week = $47.86 + $ 2 = $49.86

The mean of 2nd week: 49.86 / 5 = $9.97

$9.97 - $9.57 = $0.40

2nd week increased 40 cents or $0.40
