Use the Pythagorean theorem to solve this problem. So, 81+x^2=1681. ( Pythagorean theorem: a^2+b^2=c^2). x^2=1600. x=40.
Answer:
x = 1/2
Step-by-step explanation:
8x-(4x-3)=5
Distribute the minus sign
8x -4x +3 = 5
Combine like terms
4x+3 =5
Subtract 3 from each side
4x+3-3 = 5-3
4x = 2
4x/4 = 2/4
x = 1/2
Answer: An example would be...
Step-by-step explanation:
($5.40+$5)C + ($3.20+$8)xC = Total Amount.
Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = ₹256
r = 100% = 100/100 = 1
n = 4 because it was compounded 4 times in a year.
t = 1 year
Therefore,
A = 256(1 + 1/4)^4 × 1
A = 256(1 + 0.25)^4
A = 256(1.025)^4
A = ₹283
The compound interest is
283 - 256 = ₹27
