Answer:
A = $1,650.24
Step-by-step explanation:
A = P(1 + r/n)^nt
Where
A = future value
P = present value = $1,600
r = interest rate = 3.1% = 0.031
n = number of periods = 4
t = time = 1 year
A = P(1 + r/n)^nt
= 1,600( 1 + 0.031 / 4)^4*1
= 1600( 1 + 0.00775)^4
= 1600(1.00775)^4
= 1600(1.0314)
= 1,650.24
A = $1,650.24
For the answer to the question above, \
Let
D = Dominic weight
R = Ralph weight
P = Peter weight
We have three unknowns so we should set up three equations. We do as follows:
D = 0.5R
P = 3D
D+R+P = 720
Solving simultaneously we obtain,
D = 120
R = 240
P = 360
<span>So the answer is 120 is the weight of Dominic</span>
Answer:
Greatest number: 9
Least number: 2
Range: 7
Step-by-step explanation:
From smallest to largest, the numbers are: 2, 3, 6, 8, 9. The largest (greatest) is 9 and the least (smallest) is 2. The range is 9-2=7.
Answer:
23
Step-by-step explanation:
2x + 3x +1 + 3x - 5 = 180
>8x -4 = 180
>8x = 184
