Answer:
1. V(12) = $ 1200
2. V(20) = $ 4800
Step-by-step explanation:
The following data were obtained from the question:
V(t) = 150 × 2ᵗ/⁴
V(12) =?
V(20) =?
1. Determination of V(12)
Time (t) = 12 years
V(12) =?
V(t) = 150 × 2ᵗ/⁴
V(12) = 150 × 2¹²/⁴
V(12) = 150 × 2³
V(12) = 150 × 8
V(12) = $ 1200
2. Determination of V(20)
Time (t) = 20 years
V(20) =?
V(t) = 150 × 2ᵗ/⁴
V(20) = 150 × 2²⁰/⁴
V(20) = 150 × 2⁵
V(20) = 150 × 32
V(20) = $ 4800
Four ninths means 4/9 and of means multiply= 4/9 × 45
=20/1
=20
Answer:
9
Step-by-step explanation:
median: The middle number after the numbers have been sorted into ascending or descending order.
Mean: The quotient of the numbers added together then divided by the amount of numbers.
So if 9 were the missing number the median would be 5 because in ascending order it would look like this:
1, 3, 5, 7, 9
and as you can see 5 is in the middle.
The mean would also be 5 because
1+ 3+ 5 + 7 +9 =25
and 25 divided by 5 equals 5
So therefore the missing number must be 9.
(Also it was obvious that they just added 2 to each number)
Words of Tasha = A
A x 120/100=54
simplify 120/100=6/5
A x 6/5=54
divide both side by 6/5
A=54/(6/5)
A=54x5/6
A=45
