Answer:
The scale factor is 1/2
Step-by-step explanation:
The coordinates of Point G are (4,6) and the coordinates of Point G' are (2,3). To get from 4 to 2 and 6 to 3, you have to multiply by 1/2. Therefore, the scale factor is 1/2.
2000 * .1 = 200 + 2000 = 2200 (First year)
2200 *.1 = 220 + 2200 = 2420 (second year )
2420* .1 = 242 + 2420 = 2662 (third year )
2662 * .1 = 266.2 + 2662 = 2928.2 (fourth year)
They spent $2928.2 on clothing for 4 years.
the common ratio is 1/5
the scale factor or start value is 500

Step-by-step explanation:
Answer:
4) 7.9%
Step-by-step explanation:
Given:
% of milk chocolate = 70%
% of white chocolate = 30%
Total number of chocolate = 20
Number of milk chocolate:
![\frac{70}{100} * 20 = 14](https://tex.z-dn.net/?f=%20%5Cfrac%7B70%7D%7B100%7D%20%2A%2020%20%3D%2014%20)
Number of white chocolate:
From the calculations, we now know there are 14 milk chocolates and 6 white chocolates.
2 white chocolates are picked at random without replacement.
Probability first chocolate picked was white: ![\frac{6}{20} = 0.3](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B20%7D%20%3D%200.3%20)
Probability second chocolate picked was white: ![\frac{5}{19} = 0.2632](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B19%7D%20%3D%200.2632)
To find probability that both of them are white chocolates, multiply probability of the first and second.
0.3 * 0.2632 = 0.07896
≈ 0.079
Convert to percentage by multiplying by 100.
0.079 * 100 = 7.9%
The probability that they are both
white chocolate is 7.9%
