Masja [62]

Answer:

We conclude that  Seth can make the model of the house on 9 different ways.

Step-by-step explanation:

We know that Seth uses 17 linking cubes to make a model house. The model house is in the shape of a rectangle and is one cube high.  

We calculate how many different ways could Seth make the model of the house:

C_8^9=\frac{9!}{8!(9-1)!}=9

We conclude that  Seth can make the model of the house on 9 different ways.

Answer:

x = 10, x = 124

Step-by-step explanation:

(5)

Since Δ JKL is isosceles then the base angles are congruent, that is

∠ LJK = ∠ LJG = 80° , thus

∠ JLK = 180 - (80 + 80) = 180 - 160 = 20

x = 20 ÷ 2 = 10

(6)

Since Δ PQR is equilateral, then each of its angles = 60°

∠QRS = 60° - 32° = 28°

Since Δ SQR is isosceles then base angles are congruent, then

∠ SQR = ∠ QRS = 28 , thus

x = 180 - (28 + 28) = 180 - 56 = 124

vovangra [49]

Answer:

B. Earnest money

Step-by-step explanation:

We have the statement,

'A buyer pays a deposit to the seller in advance before completing the transaction'.

'Earnest money' is 'the amount deposited by the buyer to the seller in advance, as a representation of a good faith to buy the required thing'.

Thus, we see that the statement represents 'Earnest money'.

So, option B is correct.
