Define a variable and write an algebraic expression for each problem. Evaluate the expression for the given values. 1. The charge for ice skating is $3 for skate rental and $2 per hour to skate. How much will you pay if you skate for: a) 2 hours? b) 4 hours? c) 3 1/2 hours?

Amount = 3 + 2t

Amount pay for 2 hours = $7

Amount pay for 4 hours = $11

Amount pay for 2 hours = $10

Step-by-step explanation:

Given:

Fixed charges = $3

Variable charges = $2 per hour

Find:

Amount pay

a) 2 hours? b) 4 hours? c) 3 1/2 hours?

Computation:

Assume time = t

So,

Amount = 3 + 2t

Amount pay for 2 hours = 3 + 2t = 3 + 2(2) = $7

Amount pay for 4 hours = 3 + 2t = 3 + 2(4) = $11

Amount pay for 2 hours = 3 + 2t = 3 + 2(3 1/2) = $10

So

The square root of 244 is 15.62 ( up-to 2 decimal places)

Step-by-step explanation:

Following is the division method for square root of 244 with rules as follows:

Make pairs of the given digit starting from right (unit place). They will be calculated one by one as formed in pairs/singles.Digit added for divisor and quotient will be same at each step.Each next dividend will be formed by subtracting product of divisor and quotient from first digit/pair.Each next divisor will be formed by taking two times of previous quotient and annexing it with suitable digit that gives equal to or less than the dividend.

Following solution gives square root of 244:
