Answer:
9
Step-by-step explanation:
Solution
Here,
(a^3)^6=(a^2)^x
or, a^18=a^2x
or, 18=2x
or, x=18/2
x=9
Given:
- Bought n items of product A at 1/5 rs each
- bought n items of product B at 1/4 rs each
He mixed the two items and sold each at 2/9 rs each.
He lost 3 rs in the above batch of articles.
Solution:
revenue = 2n* (2/9) rs = 4n/9 rs
cost = n/5+n/4 rs = n(1/5+1/4)
Profit = revenue-cost = 4n/9-n(1/5+1/4) = -3 rs
Solve for n
4n/9-n(1/5+1/4) = -3
factor out n
n(4/9-1/5-1/4)=-3
n(80-36-45)/180=-3
-n/180=-3
n=3*180=540
Total number of products bought
= n+n = 540+540 = 1080
Answer:
D
Step-by-step explanation:
Answer:
-28 = x
Step-by-step explanation
[5x + 20] + [4x - 8] = 180
9x + 12 = 180
- 12 -12
______________
9x = 168
18⅔ = x
m∠EBC = 5[18⅔] + 20 = 113⅓
93⅓

Answer:
Interes= 162,58
Step-by-step explanation:
Dada la siguiente información:
Se deposita 4000 soles a una tasa de interés del 0,8% quincenas
<u>Primero, debemos calcular el valor final de la inversión:</u>
VF= [VP*( 1 + i)^n]
VF= 4.000*(1,008^5)
VF= 4.162,58
<u>Para calcular el interés ganado en 5 quincenas, debemos usar la siguiente formula:</u>
Interes= 4.162,58 - 4.000
Interes= 162,58
