Answer:

-- Purple55 is correct! --

bc-c^{3} = 8

Step-by-step explanation:

We know...

a=4\\(b=8)\\(c=2)\\d=7\\e=3\\f=9\\g=10

now just plugin bc-c^{3} = 8(2) - (2)^{3} from here we just need to solve it!

8(2)-(2)^{3} \\=16-8\\=8

I hope this helps you!

A department store sells a pair of shoes with an 87% markup. If the store bought the pair of shoes for $55.25, what is the selli
kolbaska11 [484]
Markup means they sell it for that percentage more than they bought it for. First let's calculate how much they will mark it up for:

\sf 55.25\cdot 87\%

Convert 87% into a decimal(87/100):

\sf 55.25\cdot 0.87

Multiply:

\sf\approx 48

This is how much they'll mark it up, now let's add it to how much they bought it for to find out the selling price:

\sf 48+55.25\approx\boxed{\sf \$ 103}

You deposit $500 into a savings account that earns 3.2% annual interest. How much is in the savings account after 10 years?
Brilliant_brown [7]
A = P(1 +r/n)^nt
P = 500
r = 3.2% = 0.032
n = 1
t = 10

A = 500(1 + 0.032)^10
A = $685.12

A questionnaire has determined that 20% of the residents of Flaugamuck County own an iPod. Furthermore, 80% of these iPod owners
nydimaria [60]

Answer:

P = 7.14%

The percentage of those 30 years or older that own an ipod is 7.14%

Step-by-step explanation:

Given;

Percentage of ipod owners Pi = 20%

Percentage who don't own ipod Pd = 100-20 = 80%

For age 30 or older;

Percentage of ipod owners who belong to this group

Po = 20% of Pi

Percentage who don't have an ipod but belong to this group Pu = 100-35% = 65% of Pd

The percentage of those 30 years or older that own an ipod is;

P = Po/(Po+Pu) × 100%

Po = 20% of Pi = 20% of 20% = 0.2×20 =4%

Pu = 65% of Pd = 65% of 80% = 0.65×80% = 52%

Substituting the values;

P = 4/(4+52) × 100%

P = 7.14%
