17. For the parallelogram, find the value of the variables. Show your work. 5x + 2 3y - 6 21 17 24=3y-6 => 30=3y, y=10, 12 =

Dafna11 [192]

In this problem, you have already shown the solution.

24 = 3y - 6 => 30 = 3y, y =10

12 = 5x + 2 => 10 = 5x , x = 2

And yes, basically parallel sides must have the same length

These are the answers:

for 17.) x = 2
y = 10

for 18.) mid segment = (side 1 + side 2) / 2 -->
19 = (24 + side2) / 2 -->
38 = 24 + side2,

thus, side 2 = 14 units

A supply company manufactures copy machines. The unit cost C (the cost in dollars to make each copy machine) depends on the numb

ArbitrLikvidat [17]

Answer:

$9327

Step-by-step explanation:

Apparently, the cost function is supposed to be ...

C(x) = 0.4x^2 -112x +17167

This can be rewritten to vertex form as ...

C(x) = 0.4(x^2 -280) +17167

C(x) = 0.4(x -140)^2 +17167 -0.4(19600)

C(x) = 0.4(x -140)^2 +9327

The vertex of the cost function is ...

(x, C(x)) = (140, 9327)

The minimum unit cost is $9327.

_____

Comment on the question

You found the number of units that result in minimum cost (140 units), but you have to evaluate C(140) to find the minimum unit cost.

Simplify and leave in radical form. 8√x^2 y^6

IrinaK [193]

Step-by-step explanation:

$\sqrt[8]{ {x}^{2} {y}^{6} } \\ \\ = ( {x}^{2} {y}^{6} )^{ \frac{1}{8} } \\ \\ = {x}^{2 \times \frac{1}{8}} {y}^{6\times \frac{1}{8}} \\ \\ = x^{\frac{1}{4}} {y}^{3\times \frac{1}{4}} \\ \\ = x^{\frac{1}{4}} {y}^{\frac{3}{4}} \\ \\ = \sqrt[4]{x {y}^{3} } \\$

A necklace regularly sells for $18.00. the store advertises a 15% discount. what is the sale price of the necklace in dollars

SSSSS [86.1K]

I can solve with 2 methods:

I. Because the discount is 15 % of 18 $ , the price will be (100-15=85) 85 % of 18 $
18*85/100= 15,3 $ ( the sale price)

II. The discount is 15 % of 18$
15*18/100= 2,7$ ( the discount)
then I decrease it from the regularly price
18$-2,7$=15,3 $ (the sale price)

Personally I believe the first is an easier method.
I hope you understand and you can apply this in every similary problem.

PLEASE I AM BEGGING help me all I need to so is show work I have to turn this in tmrw pls

GenaCL600 [577]

Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

Let's consider all the information given:

Eddie's pension is based on the average of his last four year's salaries

$\hookrightarrow \text{average } = \text {sum of all salaries} / \text{ number of years}\\ \hookrightarrow \text{average}= 392000 / 4 = 98000$

2. The employer will pay 1.2% of that average for each year he worked

$\hookrightarrow \text{1.2 percent of average} = \frac{1.2}{100} *98000=1176$

3. The employer will therefore pay in total

$\hookrightarrow \text{Total pension} = 1176 * 20 \text{ years} = 23520$

Answer: $23520

Hope that helps!
