bearing in mind that there are 60 minutes in 1 degree and 60 seconds in 1 minute.

let's start off by subtracting the degrees, 60° - 30° = 30°.

now, we have 50'40", let's make them all in seconds, let's see 50*60 = 3000 seconds plus 40 = 3040 seconds.

40'50" is 40*60 = 2400 seconds plus 50 = 2450 seconds.

3040' - 2450' = 590'.

so is really 30°590", let's get the minutes from that,  590/60 gives us a quotient of 9 and a remainder of 50, so is 9 minutes and 50 seconds.

<h2>30° 9' 50".</h2>

uranmaximum [27]

Answer:

$2,400

Step-by-step explanation:

Ken intends to start a savings account

10% = leisure spending

This means 90% = Expenses for school

Let us represent the amount he must save as : x

Hence in other for him to have $2,160 in his savings account, the amount Ken must earn is calculated as:

90/100 × x = $2,160

Cross Multiply

90x = $2,160 × 100

x = ($2,160 × 100) ÷ 90

x =$2,400

Therefore, the amount Ken has to earn to have the amount needed for school is $2,400
