Answer:
Ravi’s present age will be 5.
Step-by-step explanation:
From the given, Let Ravi’s present age is taken as "a" years.
After 15 years, his age = (a+15) years.
By the given, it is identified that the age of Ravi after 15 years is equal to the 4 times of his present age.
Given,

Then, it has been found that the present age of Ravi is 5 when his age after 15 years will be 4 times of his present age.
Answer:
B. 12
Step-by-step explanation:
SO 2/3 of 18 is basically saying multiply them together
Every time you see the word “of” Basically means multiply.
23*18=12
we know that
the area of the rectangular banner is equal to

where
W is the wide of the banner
h is the height of the banner
in this problem


In the formula of the area solve for h

Substitute the values of W and A

therefore
the answer is
the height of the banner is 
A = c/sin C, and b by the proportion b/sin B = c/sin C.
a/sin 37° = 4380/sin 109°
a sin 109° = 4380 sin 37°
a = 4380 sin 37°/sin 109° ≈ 2787.8
b/sin 34° = 4380/sin 109°
b sin 109° = 4380 sin 34°
b = 4380 sin 34°/sin 109° ≈ 2590.4
