Answer:
First of all you need to find the total ratio in order to find the number of seeds in each garden.
Total ratio = 3 + 5+7
= 15
The number of seed in garden a = ratio of garden a/ total ratio x 1500
= 3/15 x 1500
= 300 seeds
since each of the seeds in garden a cost 10 cents , then the cost of 300 seeds = 300 x 10 = 3000 cents
= $ 30 ( 100 cents = $1 )
The number of seeds in garden c = 7/15 x 1500
= 700 seeds
each seed in garden b cost 5 cent, cost of 500 = 700 x 5 = 3500 cents
= $35
The number of seeds in garden b = 5 / 15 x 1500 = 500 seeds
It was said that $ 110 was pent in all, so the amount spent on c = $110 - ( $30 + $35)
= $110 - $65
= $45

Answer:
140
Step-by-step explanation:
<u>As per picture:</u>
∠PTQ and ∠RTS are vertical angles and they are equal
- ∠PTQ = (x + 28)°
- ∠RTS = (2x + 16)°
- ∠PTQ = ∠RTS
- x + 28 = 2x + 16
- 2x - x = 28 - 16
- x = 12
∠PTR is supplementary with ∠PTQ and their sum is 180°
- ∠PTQ = 12 + 28 = 40°
- ∠PTR = 180 - 40 = 140°
Answer:
The answer would be D.
