Answer:

Let's see...

Step-by-step explanation:

The first coin is a quarter.
The second, third, fourth, and fifth coins are dimes.
The sixth, seventh, and eighth coins are nickels.

That being said, what is the total value of the cents?

cents = ¢

<u>Values:</u>

Quarter = 25 ¢

Dime = 10 ¢

Nickel = 5 ¢

So,

1 quarter + 4 dimes + 3 nickels = total cents

25 + 10 + 10 + 10 + 10 + 5 + 5 + 5 = total cents

25 + 40 + 5 + 5 + 5 = total cents

25 + 40 + 15 = total cents

25 + 55 = total cents

80 = total cents

At a sale, dresses were sold for $90 each. This price was 75% of a

gulaghasi [49]

Answer:

A dress originally costs $120

Step-by-step explanation:

To find the original cost of the dress, we will follow the steps below;

let x represent the original cost of the dress

75% of x = $90

$\frac{75}{100}$ × x = $90

$\frac{75X}{100}$ = $90

MULTIPLY both-side of the equation by 100

$\frac{75X}{100}$ × 100 = $90×100

At the right-hand side of the equation, 100 will cancel out 100, leaving us with just 75x

75x = $9000

DIVIDE both-side of the equation by 75

75x/75 = $9000/75

At the left-hand side of the equation 75 will cancel-out 75 leaving us with just x

x= $9000/75

x = $120

A dress originally costs $120

A(1, 1), B(7, 1), C(1, 9)

AB = 7 - 1 = 6

AC = 9 - 1 = 8

Use the Pythagorean theorem:

AB² + AC² = BC²

Substitute:

BC² = 6² + 8²

BC² = 36 + 64

BC² = 100 → BC = √100 → BC = 10

The perimeter of ΔABC:

P = 6 + 8 + 10 = 24

<h3>Answer: 24 units</h3>

The current (2015) population of Eugene is approximately 155,000 people. a) If the population growth rate remains at 4% per year

Olegator [25]

$\bf \textit{Amount of Population Growth}\\\\
A=Ie^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &500,000\\
I=\textit{initial amount}\to &155,000\\
r=rate\to 4\%\to \frac{4}{100}\to &0.04\\
t=\textit{elapsed time}\\
\end{cases}$

$\bf 500000=155000e^{0.04t}\implies \cfrac{500000}{155000}=e^{0.04t}\implies \cfrac{100}{31}=e^{0.04t}
\\\\\\
\textit{now, we take \underline{ln} to both sides}
\\\\\\
ln\left( \frac{100}{31}\right)=ln(e^{0.04t})\implies ln\left( \frac{100}{31}\right)=0.04t\implies \cfrac{ln\left( \frac{100}{31}\right)}{0.04}=t$

so it will have 500,000 approximately "t" years after 2015.
