ANSWER

Given that Δ ABC ~ ΔDEF

solve for x

To proof

as given in the question

ΔABC ~ ΔDEF

this means their sides are proportional to each other.

thus

\frac{AB}{AC} = \frac{ED}{DF}

As given

AB = 30unit

AC = 24unit

ED = 5unit

DF = x

put  in the above

x = \frac{5\times24}{30}

solving

x = 4 unit

option (C) is correct

Hence proved

konstantin123 [22]
If you would like to know how many dolls did Bob and Carol break today, you can calculate this using the following steps:

On average, they break: 12% of 175 = 12/100 * 175 = 21 dolls.
Today: 2/3 as many dolls as usual = 2/3 * 21 = 14 dolls

Result: Bob and Carol broke 14 dolls today.

Your family goes to a restaurant for dinner. There are 7 people in your family. Some order the chiken dinner for $ 12 dollars an
aleksandrvk [35]

Answer:

The number of people who ordered steak dinner is 5

The number of people who ordered chicken dinner is 2

Step-by-step explanation:

Given as :

The total number of people went for the dinner = 7

The total bill price for the dinner = $ 109

The price for the chicken dinner = $ 12

The price for the steak dinner = $ 17

Let The number of people who ordered chicken dinner = c

And The number of people who ordered steak dinner = s

Now, According to question

The total number of people went for the dinner = The number of people who ordered chicken dinner + The number of people who ordered steak dinner

Or, c + s = 7

And The total bill price for the dinner = The price for the chicken dinner × The number of people who ordered chicken dinner + The price for the steak dinner ×  The number of people who ordered steak dinner

Or, $ 12 × c + $ 17  × s = $ 109

Now, solving the equations

$ 12 × ( c + s ) = $ 12 × 7

Or,  $ 12 × c + $ 12  × s = $ 84

Or, (  $ 12 × c + $ 17  × s ) - (  $ 12 × c + $ 12  × s ) = $ 109 - $ 84

Or , (  $ 12 × c - $ 12  × c ) +  (  $ 17 × s - $ 12  × s ) = $ 25

Or, ( 0 ) + ( $ 5 s ) = $ 25

∴ s = \frac{25}{5}

I.e s = 5

So, The number of people who ordered steak dinner = s = 5

Put the value og s in Eq A

∵,  c + s = 7

or,  c = 7 - s

Or, c = 7 - 5

I.e   c = 2

So , The number of people who ordered chicken dinner = c = 2

Hence The number of people who ordered steak dinner is 5

And The number of people who ordered chicken dinner is 2   Answer
