Answer:

Scale Factor: 343; 82320/240

Step-by-step explanation:

Haven't done scale factors in a long time, so I'll try my best.

The scale factor wants the model to real sculpture, so...

Model: $6*5*8 = 240$

Sculpture: $42*35*56=82320$

$\frac{82320}{240} =343$

So, the scale factor for the model to sculpture would be 343. The fraction that creates the scale factor is $\frac{82320}{240}$ .

2. Triangle ABC is equilateral and AB = 6x + 3, BC = 8x - 1,2. AB =

kherson [118]

Answer:

AB = BC = AC = 15

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent.

Equate any 2 sides and solve for x , that is

AC = AB , so

11x - 7 = 6x + 3 ( subtract 6x from both sides )

5x - 7 = 3 ( add 7 to both sides )

5x = 10 ( divide both sides by 5 )

x = 2

Then

AC = 11x - 7 = 11(2) - 7 = 22 - 7 = 15 , thus

AB = BC = AC = 15

Sergeeva-Olga [200]

Step-by-step explanation:

since for one muffins we need 20.35 g of flour

then for 700 muffins we need 20.35×700=14245g

14245g= 14.245kg

since she has 10.8kg then she needs extra (14.245-10.8)kg

=3.445kg
