2.65=3x(25)+x(10)+(x-1)(5)
9 quarters 3 dimes 2 nickels
9*.25+2.25
3*.10=.30
2*.5=10
2.25+.30+.10=2.65

We can write an equation in terms of n, the amount of nickels:

25(3n+3)+10(n+1)+5n=265.

Thus:

90n+85=265

Subtracting 85, we have:

90n=180

Therefore, n=2.  As such, Danielle has 2 nickels, 3 dimes, and 9 quarters.

Bianca works as a content writer for $ 10 an hour and as a library assistant for $ 14 an hour. This month, she worked a combined
trasher [3.6K]

It's given in the question,

  • Bianca works as a content writer for $10 per hour.
  • She works as a library assistant for $14 per hour.

She worked for a combined total of 75 hours for both the jobs this month.

Let c be the number of hours Bianca worked as a content writer.

Her earning for this month as a content writer = $10c

Her working hours as library assistant this month = (75 - c) hours

Therefore, her earning as a library assistant for the month = $14(75 - c)

By adding the earnings as a library assistant and a content writer for the month = $10c + $14(75 - c)

           = (10c - 14c) + 1450

           = $(9c + 1050)

    Therefore, expression for the combined total amount she earned this month will be $(9c + 1050).

A cylinder has diameter 34 m and height 27 m. A label at bottom states drawing not to scale.
Blababa [14]

Answer:

Therefore,

Volume of the cylinder is 24501.42 m³.

Step-by-step explanation:

Given:

Height of Cylinder = 27 m

Diameter, d = 34 m

Radius = \dfrac{d}{2}=\dfrac{34}{2}=17\ m

Volume of a Cylinder = ?

Solution:

We know that

\textrm{Volume of a Cylinder}=\pi (Radius)^{2}\times Height

Substituting the given values in formula we get

\textrm{Volume of a Cylinder}=3.14 (17)^{2}\times 27=24501.42\ m^{3}

Therefore,

Volume of the cylinder is 24501.42 m³.
