Answer & Step-by-step explanation:
number of Dave's coins = number of Zack's coins + 5
The question is asking to find the difference in prices paid (thus "<em>more</em>"), completely unrelated to the number of coins Zack bought as these two numbers are independent of one another. The difference in price can be found by simply multiplying the cost of one coin by 5.

Answer:
573440 kg
Step-by-step explanation:
Given,
Density of copper ( D ) = 8960 kg / m³
Length of cube ( l ) = 4 meters
To find : Mass of solid cube of copper ( m )
Formula : -
Volume of cube = l³
Volume of cube
= l³
= 4³
= 4 x 4 x 4
= 64 meter³
So,
V = 64 meter³
Formula : -
D = m / V
m = D x V
= 8960 x 64
m = 573440 kg
Hence,
The mass of a solid cube of copper is <u>573440</u> kg.

Answer: it would be worth $11925 when it matures after 7 years.
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount invested in the CD.
R represents interest rate on the amount invested in the CD.
T represents the duration of the investment in years.
From the information given,
P = $10,000
R = 2.75%
T = 7 years
I = (10000 × 2.75 × 7)/100
I = $1925
Therefore, the worth of the CD in total at the end of 7 years when the CD matures is
10000 + 1925 = $11925
