Alicia cashed her paycheck and used half her earnings to take three friends out to dinner. She spent $42.15 and she brought home
Phoenix [80]
If you would like to write an inequality to represent the situation, using X to represent the amount of Alicia's paycheck, you can calculate this using the following steps:

X ... the amount of Alicia's paycheck

X/2 - $42.15 >= $20
X/2 >= $20 + $42.15
X/2 >= $62.15     /*2
X >= $62.15 * 2
X >= $124.3

The correct result would be <span>X >= $124.3</span>.

Complete the following conversions. i) 1 mm = m ii) mm = 1 m iii) 1 cm = m iv) cm = 1 m v) 1 km = m vi) km = 1 m vii) 1 cm = mm
Gelneren [198K]

The unit conversion for the given values are explained below.

<h3>What is unit conversion?</h3>

Unit conversion is the process of changing a quantity's measurement between different units, frequently using multiplicative conversion factors.

The following measurements: length, weight, capacity, temperature, and speed are all measured in units.

Some basic unit conversions are-

  • 1 Km = 1000 m
  • 1 m = 100 cm
  • 1 m = 1000 mm
  • 1 cm = 10 mm

There are two methods to convert the units

  1. To convert smaller unit into larger divide the number by conversion factor.
  2. To convert larger value into smaller value multiply by the conversion factor.

The unit conversion for the following factors are-

i) 1 mm = _ m

Here, conversion is from smaller to larger. So, divide by conversion factor.

  1 mm = (1/100)m

ii) _ mm = 1 m

Here, conversion is from larger to smaller. So, multiply with conversion factor.

  1000 mm = 1 m

iii) 1 cm = _ m

Here, conversion is from smaller to larger. So, divide by conversion factor.

   1 cm = (1/100)m

iv) _ cm = 1 m

Here, conversion is from larger to smaller. So, multiply with conversion factor.

  100 cm = 1 m

v) 1 km = _m

Here, conversion is from larger to smaller. So, multiply with conversion factor.

  1 km = 1000 m.

vi) _ km = 1 m

Here, conversion is from smaller to larger. So, divide by conversion factor.

(1/1000) km = 1 m.

vii) 1 cm = _mm

Here, conversion is from larger to smaller. So, multiply with conversion factor.

   1 cm = 10 mm

viii) _cm = 1 mm

Here, conversion is from smaller to larger. So, divide by conversion factor.

   (1/10) cm = 1 mm.

Terry has just purchased a new car, which had a list price of $16,825. She had to pay 7.19% sales tax, a $1,128 vehicle registra
Anarel [89]
Total cost of purchasing the car = $16,825 + 0.0719 x $16,825 + $1,128 + $190 = $19,352.72
Value of her previous car = 0.9 x $16,825 = $15,142.50

Amount being owed by Terry = $19,352.72 - $15,142.50 = $4,210.22

The present value of annuity is given by PV = P(1 - (1 + r/t)^-nt) / (r/t)
where P is the monthly payment, r is the rate = 10.59% = 0.1059, t is the number of periods in a year = 12, n is the number of years.

4,210.22 = P(1 - (1 + 0.1059/12)^-(5 x 12)) / (0.1059/12)
0.1059(4,210.22) = 12P(1 - (1.008825)^-60)
P = 445.862298 / 4.916774288 = 90.68

Amount of interest paid = 60(90.68) - 4,210.22 = 5440.80 - 4210.22 = $1230.58
