Answer:
Step-by-step explanation:
suface area of base=1/2×9×7.8=9×3.9=35.1 yd²
lateral surface area=3×1/2×9×10=135 yd²
total surface area=135+35.1=170.1 yd²
i assumed it is an equilateral triangular base.
as √(7.8²+4.5²)=9.0049≈9
D because of lx w x h and you would get one cubic unit
Answer:
changing the currency $ to #
$1000 = #415,640.00
i=prt (formular)
given:
I =?
p = $1000 or #415,640.00
r = 6%
t = 2 years
i= 415,640.00×6×2÷100
i= #49876.8
without changing currency
i= 1000×6×2÷100
i=120
Answer:
Hey there!
We have that 4/5, or 80% of the 60 students passed the exam.
Thus, we have:
0.8(60)=48
48 students passed the exam.
Let me know if this helps :)
If so:
f(n) = 2n² + 4
for n= 0 → f(0) = 2(0) + 4 → f(0) = 4
for n= 1 → f(1) = 2(1²)+ 4 → f(1) = 6
for n= 2 → f(2) = 2(2²)+ 4 → f(2) = 12
for n= 3 → f(3) = 2(3²)+ 4 → f(3) = 22 and so on and so forth
