Answer:
length = 26 cm
width = 4 cm
Step-by-step explanation:
A = 104 cm²
A = length x width
ratio of length and width = 13 : 2
total ratio of length and width is 15 = a
so ratio of length is (13/15)a and width (2/15)a
A = length x width = (13/15)a x (2/15)a = (26/225)a² = 104
a² = 104 x 225 : 26 = 900
a = 30cm
length = (13/15)a = 13/15 x 30 = 26 cm
width = (2/15)a = 2/15 x 30 = 4 cm
Answer:
Step-by-step explanation:Let a be the length of line
from question we know that
a+3 is another line
Here
a+(a+3)=15. ( Given in question )
2a = 15 -3
2a=12
a=12/2
a=6
Here a and a +3 are the length of the line
Finally ,6 and 9 are the lengths
Answer:
1/3
Step-by-step explanation:
6+4+5=15 total number of balls
blue = 5 balls
5/total number = 5/15
=1/3
we have (6/7c)^2 = (6^2)/(7c)^2 = 36/49c^2
so the answer is D
ok done. Thank to me :>
