Answer:
we know
simple interest=principal×time×rate/100
then
S.I=($200×5×2)/100
so S.I=$20
For every 7 boys, there is one girl
So: 63/7 = 9
There are 9 girls.
Answer:
7.3
Step-by-step explanation:
In order to find the hypotenuse, we just need to use the Pythagorean Theorem.
Remember, that this theorem only works for right triangles.
This theorem states that a^2+b^2=c^2
This is where a and b are legs of the triange, and c is the hypotenuse.
Knowing this, we can plug our values in.
6.4^2+3.5^2=c^2
Simplify.
41.344+12.25=c^2
53.594=c^2
Root both sides.
c=7.32 (about)
Round that to tenths.
c=7.3
The answer is 68 hope this helps
Answer:
113 
Step-by-step explanation:
top rectangle = l x w = 6 x 13 = 78
lower rectangle width = 13-8=5. so a = l x w. 7 5 = 35
78+35= 113
