Answer:

\boxed{ \text{B. }\frac{2}{ 3}}

Step-by-step explanation:

The scale factor (C) is the ratio of corresponding sides of the two pyramids.

The ratio of the areas is the square of the scale factor.

\frac{A_{1}}{ A_{2}} =C^{2}\\ \\\frac{48 }{108} = C^{2}\\\\ \frac{4}{9} = C^{2}\\\\ C = \frac{2}{3}\\\\

The scale factor is \boxed {\frac{2}{3}}.

What is the first step in finding 383 divided by 30
zepelin [54]
See how many times 30 fits into 383.
30 x 12 = 360, 30 x 13 = 390
therefore, 30 fits into 383 twelve times.
383 - 360 = 23
you'll have a remainder of 23

Help a brother out!!! Math prom worth 20!! And explain please
Reil [10]
A.

ratio 1 to 1

alright
find the distance between the x values and the y values and seperate each into that ratio
1:1
A to B is (6,12) to (15,-4)
disatnce from 6 to 15 is 9, ratio would be 4.5:4.5=1:1
distance from 12 to -4 is 16, ratio would be 8:8=1:1
so the point would be (4.5,8)




b.
5:2
5+2=7
alright
A to C
(6,12) to (20,12)
distance from 6 to 20 is 14, 14/7=2, 2 times 5=10
distance from 12 to 12=0, so same coordinate
the point is (10,12)


c.
2+3=5

C to B
C is (20,12) and B is (15,-4)
distance from 20 to 15 is 5, so 2 is the x value
distance from 12 to -4 is 16, 16/5 times 2=32/5
the point is (2,32/5)

Please need this answer fast it is the last piece to my pie chart for math!!!! A catering service offers 3 appetizers, 5 main co
Brut [27]
To find in how many ways this can be done, we can use the method of combination.

As the customer have to choose 2 out of 3 appetizers, the combination would be 3C2.

For 4 out of 5 main courses, the combination wouls be 5C4.

For 6 out of 8 desserts, the combination would be 8C6.

We can then combine them into a single equation to find the answer:

3C2 x 5C4 x 8C6
=420

Therefore, the answer is 420 ways.

Hope it helps!

∠E∠E and ∠F∠F are vertical angles with m∠E=9x+12m∠E=9x+12 and m∠F=3x+24m∠F=3x+24 .
Mama L [17]

Since ∠E and ∠F are vertical angles, they are congruent, meaning that m∠E = m∠F

Plugging in the equations that were originally given, we can form the equation 9x + 12 = 3x + 24

Subtract both sides of the equation by 3x

6x + 12 = 24

Subtract 12 from both sides

6x = 12

Divide both sides by 6

x = 2

This should be your answer. Have an awesome day! :)
