Answer:

Step-by-step explanation:

85% of x = 17

$\frac{85}{100}*x = 17\\\\ x = 17*\frac{100}{85}\\\\x = \frac{100}{5}\\\\x = 20$

Refer to Table 4-4. If these are the only four sellers in the market, then the market quantity supplied at a price of $4 is

NeTakaya

All things being equal; demand decreases, as price increases.

The quantity supplied when price is $4 is 28

From table 4.4 (see attachment).

When price = $4, we have the following supplies:

Firm A = 6
Firm B = 6
Firm C = 8
Firm D = 10

So, the total supply at $4 is:

$Total = 4 + 6 + 8 + 10$

$Total = 28$

Hence, the quantity supplied when price is $4 is 28

12. In the given figure, RS is parallel to PQ, If RS = 3 cm, PQ = 6 cm and ar(∆TRS) = 15cm³, then ar (∆TPQ) = ? (a) 70 cm² (b) 5

Gnesinka [82]

$\large\underline{\sf{Solution-}}$

Given that,

In triangle TPQ, 

RS || PQ,

RS = 3 cm,

PQ = 6 cm,

ar(∆ TRS) = 15 sq. cm

As it is given that, RS || PQ

So, it means

⇛∠TRS = ∠TPQ [ Corresponding angles ]

⇛ ∠TSR = ∠TPQ [ Corresponding angles ]

$\rm\implies \: \triangle TPQ \: \sim \: \triangle TRS \: \: \: \: \: \: \{AA \}$

Now, We know 

Area Ratio Theorem,

This theorem states that :- The ratio of the area of two similar triangles is equal to the ratio of the squares of corresponding sides.

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{ar( \triangle \: TRS)} = \dfrac{ {PQ}^{2} }{ {RS}^{2} }$

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15} = \dfrac{ {6}^{2} }{ {3}^{2} }$

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15} = \dfrac{36 }{9}$

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15} = 4$

$\rm\implies \:ar( \triangle \: TPQ) = 60 \: {cm}^{2}$
