Answer:
$51,557.00
Step-by-step explanation:
1100 times 9% = 99 a year
99 times 43 = 4257
1100 times 43 =47,300
then you add 47,300 + 4257 = 51,557
you take your total that she put into the ira and multiply it by 9%
then you multiply that total by the number of years before she retires which is 43
so 99 times 43 = 4257
then you will multiply how much she put in the ira at the beginning of the year which is 1100 by the 43 years before she retires which is 47,300
then you add your totals together
4257 + 47,300 = 51,557
Answer:
£495 million
Step-by-step explanation:
To find out the total cost of the land, we need to first calculate the area of the land.
Step 1: Find area of right angled triangle ADC
AD = 5 km,
DC = 12 km
Area of the right triangle = ½*a*b
a = 5km
b = 12km
Area = ½*5*12
= 5*6
Area of ADC = 30 km²
Step 2: Find the area of triangle ABC
First, let's find the length of AC using Pythagorean theorem
AC² = AD² + DC²
AC² = 5² + 12² = 25 + 144
AC = √169
AC = 13km
Area of ∆ABC = ½*AB*AC*sin(30°)
= ½*6*13*0.5
= 3*13*0.5
Area of ∆ABC = 19.5 km²
Total area of the land = area of ∆ADC + ∆ABC = 30 + 19.5 = 49.5 km²
Step 3: calculate how much the land costs
If the land costs £10 million per km²,
Cost of 49.5 km² = 49.5 × 10 = £495 million
