Since there are equal of each and there are four colors it is out of four, now because it is an equal amount of each color and there are two colors then there is a 2/4 chance of pulling a red or blue marble.

Answer:
a)
10 markers : 7 USD
24 markers : 14 USD
42 markers : 21 USD
b)
64 markers : 28 USD
Step-by-step explanation:
10 markers : 7 USD
24 markers : 14 USD
For 10 markers, the price is 7 USD;
For 14 additional markers, the price increased by 7 USD;
Following the pattern, an additional 18 markers would see the price further increase by 7 USD;
So:
24 + 18 = 42
42 markers : 21 USD
Then, an additional 22 markers would cost 7 USD more than this;
42 + 22 = 64
64 markers : 28 USD
(a) ET = 18 and WE = 12
(b) FA = 16/3
HF = 8/3
ET = 8
WE = 4
<u>Explanation:</u>
WT = 30 ( WE + ET = 30)
WE = 30 - ET
2FA = 3HF
FA = 3/2HF
WE =?, ET = ?
Line WH, EF and TA are parallel to each other.
(a)
ΔWTA and ΔWHA are congruent to each other
Therefore, by congruency
So,
30 - ET/ ET = HF / 3/2HF
30 - ET / ET = 2HF / 3HF
30 - ET / ET = 2/3
On solving the above equation we get, ET = 18
WE = 30 - ET
WE = 30 - 18 = 12
Therefore, ET = 18 and WE = 12
(b)
HA = 8 ( HF + FA = 8)
HF = 8 - FA
WT = 12 ( WE + ET = 12 )
WE = 12 - ET
GA = 2WG
HF, WA, WE, ET = ?
ΔWHA and ΔGFA are congruent
So,
8 - FA / FA = WG / 2 WG
On solving the above equation we get,
FA = 16/3
HF + FA = 8
HF + 16/3 = 8
HF = 8/3
ΔWTA and ΔWEG are congruent
So,
12 - ET / ET = WG / 2WG
On solving the above equation, ET = 8
WE = 12 - ET
WE = 12 - 8
WE = 4
Therefore, FA = 16/3
HF = 8/3
ET = 8
WE = 4
