Answer: sorry I'm doing a competition for who ever reaches 1k points
So the equation is A= P * B
Answer:
x = 
Step-by-step explanation:
Using the rule of exponents
= 
Note that 8 = 2³ and 2 = 
, then
= , that is
=
Since the bases on both sides are equal, equate the exponents
3x = 1 ( divide both sides by 3 )
x =
Answer:
Step-by-step explanation:
The simple interest on a certain sum for 5years at 8% per annum is Rs200 less than the simple interest on the same sum for 3years and 4months at 18% per annum.Find the sum
The formula for Simple Interest = PRT
From above question, we have to find the Principal
The simple interest on a certain sum for 5years at 8% per annum is Rs200
Hence,
R = 8%
T = 5 years
Rs 200 = P × 8% × 5
P = 200/8% × 5
P = Rs500
The principal = Rs 500
The simple interest on the same sum for 3years and 4months at 18% per annum.
Simple Interest = PRT
R = 18%
T = 3 years and 4 months
Converted to years
T = 3 + (4 months/12 months)
T = 3.33 years
Hence,
Simple Interest = Rs 500 × 18% × 3.33 years
= Rs 299.7
Speed can be broken down to distance / time.
If we know Justin drive for 2 hours before lunch and his trip was 5 hours total, then we know he drove for 3 hours at the increased speed.
2 hours * the original speed will give us the distance traveled before lunch, and 3 hours * the increased speed will give us the distance traveled after lunch. The sum of these distances is 330 miles.
2x + 3(x + 10) = 330
5x = 300
The original speed was 60 mph.
