Answer:

Expression for the combined total dollar amount she paid for her class fees is  (2185 - 17 w)

Step-by-step explanation:

Let Donna  is taking w credit hours at Westside.

Total combined credit hours at two schools =  19 hours

So, the number of credit hours at Pinewood  =  19 - w

The per hour fees credit of Westside community college = $98

So, the total fees paid for w hours  = w x Fees per hour

= w ( $98)  = $(98w)

⇒The fees Donna pays at Westside community college =  $ (98 w)

The per hour fees credit of Pinewood community college = $115

So, the total fees paid for (19 -w) hours  = (19 -w) x Fees per hour

= (19 -w) ( $115)  = $(2185 - 115 w)

⇒The fees Donna pays at Pinewood community college =$(2185 - 115 w)

Hence, the total fees paid by Donna

= Fees at Westside + Fees at Pinewood

= $ (98 w)  + $(2185 - 115 w)

= $(2185 - 17 w)

Hence, expression for the combined total dollar amount she paid for her class fees is $(2185 - 17 w)

A factory adds three red drops and two blue drops of coloring to white paint to make each pint purple The factory will make 50 g
Radda [10]

30 gallons of red paint  &  20 gallons of blue paint

Step-by-step explanation:

The ratio of red to blue paint drops to make purple paint is 3 : 2

Therefore the total number of gallon, in this case, fifty (50) is equivalent to the total of two ratios (which is 3 + 2 5)

If 5 in the ratio = 50; what about 2  & 3

5 = 50

2 = x

After cross multiplication;

5x = 50 * 2

X = 100/5

X = 20

The same for ratio 3

5 = 50

3 = y

5y = 50 * 3

y = 150/5

y = 30

The answer is therefore; 30 gallons of red paint to 20 gallons of blue paint

Jim’s father is older than 40 but younger than 50.If you can divide his age by 2,4,5,8,or 10 ,there will be a remainder of 1. Ho
CaHeK987 [17]

Answer:

Step-by-step explanation:

all you have to do is divide each number by 4, 41, 42, 43, 44, 45, 46, 47, 48, 49 ,and 50 until you get a remainder of 1. what I mean is do 2 divided by all the number from 40 50 and do the same with 4,5,8 and 10 until you find one of them that has a remainder of 1. (is a lot of work sorry could't tell you the anwer)

Which expression is equivalent to 3x + 14 + 3x + 10?
NemiM [27]
So,

3x + 14 + 3x + 10

Let's put the placeholders together to make it simpler.

3x + 3x + 14 + 10

Collect Like Terms
6x + 24

This is simplified.

Option D, when multiplied, gives 6x + 24.  So that is the correct option.

find the area of a regular hexagon with an apothem 10.4 yards long and a side 12 yards long. round your answer to the nearest te
irakobra [83]
The answer is 374.4 yards.

There are 2 ways to calculate the area of a <span>a regular hexagon.
It is given:
apothem: b = 10.4 yards
side: a = 12 yards

1. The direct way is to use the formula for the regular hexagon without using an apothem:
</span>A= \frac{3 \sqrt{3} }{2} a^{2}
<span>where
A - the area of the </span><span>hexagon
a - the side of the </span><span>hexagon

Therefore:
</span><span>A= \frac{3 \sqrt{3} }{2} 12^{2}
</span><span>A= \frac{3 \sqrt{3} }{2} 144
</span><span>A= 374.4
</span>
2. The indirect way is to sketch the hexagon with 3 diagonals and create 6 triangles. Then, it is necessary to calculate the area of one triangle and multiply it by 6. In this triangle, apothem is actually the height.
The area of the hexagon is:
A = 6 · A₁
where:
A - the area of the <span>hexagon,
</span>A₁ - the area of the triangle

A_{1}= \frac{a*h}{2}

where
h - <span>height of the triangle.
</span>

Since apothem (b) of the hexagon is the height (h) of the triangle, then:
A_{1}= \frac{a*h}{2}
<span>A_{1}= \frac{12*10.4}{2}
</span><span>A_{1}= 62.4
</span>
Thus, the area of one triangle is 62.4 yards.

To calculate the area of the hexagon, we will multiply it by 6:
<span>A = 6 · A₁
</span><span>A = 6 · 62.4
</span>A = 374.4 yards

<span>In both cases, the result is 374.4 yards.</span>The answer is
