Answer:
yes
Step-by-step explanation:
First we should find a GCF for the number of boys and girls.
The gcf for the two would be 4.
Divide.
20/4 = 5
28/4= 7
therefore the ratio for boys to girls would be 5 to 7
The answer will be 11.9988.
Your Welcome :]
There are 50 sections.
Step-by-step explanation:
Given,
Length of section = 10 meters
Total length of guardrail = 0.5 km
We will convert this length in meters.
1 km = 1000 meters
0.5 km = 0.5*1000 = 500 meters
Now,
No. of sections =
No. of sections =
No. of sections = 50
There are 50 sections.
R + t + L = 5(24).....r + t + L = 120
6r + 4t + 3L = 610
r = 2(t + L).......r = 2t + 2L
2t + 2L + t + L = 120
3t + 3L = 120
6(2t + 2L) + 4t + 3L = 610
12t + 12L + 4t + 3L = 610
16t + 15L = 610
16t + 15L = 610
3t + 3L = 120 ...multiply by -5
-------------------
16t + 15L = 610
-15t - 15L = - 600 (result of multiplying by -5)
-------------------add
t = 10
3t + 3L = 120
3(10) + 3L = 120
30 + 3L = 120
3L = 120 - 30
3L = 90
L = 90/3
L = 30
r = 2(t + L)
r = 2(10 + 30)
r = 2(40)
r = 80
so for all the bouquets, there are 80 roses, 30 lillies, and 10 tulips....but there are 5 bouquets...
so each bouquet has :
80/5 = 16 roses <==
10/5 = 2 tulips <==
30/5 = 6 lillies <==
