2 1/4 * 1 3/8 = 3 3/32 or 99/32
Answer:
The answer is a = 4.5
Step-by-step explanation:
To find this we start by dividing away the coefficient of a.
10a = 45 ----> Divide both by 10
a = 4.5

Answer:
40 ft
Step-by-step explanation:
The post is 8/12 = 2/3 as tall as the shadow is long. We expect the same relationship holds for the tree.
tree height = (2/3)(shadow length) = (2/3)(60 ft) = 40 ft
The tree is 40 feet tall.
Answer:
$1,618.67
Step-by-step explanation:
converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year.
Putting time into years for simplicity,
7 months / 12 months/year = 0.583333 years.
Solving our equation:
A = 1600(1 + (0.02 × 0.583333)) = 1618.666656
A = $1,618.67
The total amount accrued, principal plus interest, from simple interest on a principal of $1,600.00 at a rate of 2% per year for 0.583333 years (7 months) is $1,618.67.
