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
Step-by-step explanation:
Let r be a radius of a given circle and α be an angle, that corresponds to a sector.
The circle area is
and denote the sector area as
.
Then
(the ratio between area is the same as the ratio between coresponding angles).
.
Answer:
No solution
Step-by-step explanation:
y = 2x + 4 (1)
-2x + y = -5 (2)
Rewrite equation (2)
y = 2x - 5
So now you have 2 equations
y = 2x + 4 (1)
y = 2x - 5 (2)
----------------------------------Subtract
0 = 9
As you know 0 is not equal 9
