Answer: 210 beats
Step-by-step explanation:
Given: A song has 28 beats in 4 seconds.
To find the rate of beats in song we need to divide 28 by 4, we get
⇒ Beats in each second of song=
To find the number of beats in 30 seconds, we need to multiply 30 to the rate of beats, we get
⇒Beats in 30 seconds of song=
Hence, there are 210 beats in 30 seconds of song.
15% I think so tho don’t trust me Bc I’m the worst person at math
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:
Answer: The last line is the answer
12 - 4x <u><</u> 20
20 - 12 = 8
-4x = 8
-4/4 = 8/-4
x = -2
New inequality: x <u>></u> -2
