An engineer performs a flow test of a cooling water system. The test equipment hooks into flow elements in the system. There are

KiRa [710]

Each flow element requires a test gauge ---> 32*80 = $2560

Each flow element needs total of 6 feet of tubing ----> 32*6 = 192 ft
price per foot = 6/100 = $.06
-----> 192*.06 = $11.52

Each 3-ft length of tubing requires 2 connectors. ----> (192/3)*2 = 128
-----> 128*2.5 = $320

Total Cost = 2560 + 11.52 + 320 = $2891.52

Subtract from budget:
3000 - 2891.52 = $108.48

Xanthia can read 100 pages per hour and Molly can read 50 pages per hour. If they each read the same book, and the book has 225

Talja [164]

Answer:

135 minutes

Step-by-step explanation:

Let

y -----> the number of pages to finish reading the book

x ----> the number of hours

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the unit rate or slope of the linear equation

b is the y-intercept or initial value

In this problem we have

<em>Xanthia</em>

$m=100\ pages/hour$

$b=225\ pages$

$y=-100x+225$ ----> the slope is negative because is a decreasing function

For y=0

substitute and solve for x

$0=-100x+225$

$100x=225$

$x=2.25\ hours$ ---> Xanthia's time to finish reading the book

<em>Molly</em>

$m=50\ pages/hour$

$b=225\ pages$

$y=-50x+225$ ----> the slope is negative because is a decreasing function

For y=0

$0=-50x+225$

$50x=225$

$x=4.5\ hours$ --- Molly's time to finish reading the book

To find out how many more minutes than Xanthia would it take for Molly to finish reading the book, subtract Xanthia's time from Molly's time

$4.5\ h-2.25\ h=2.25\ h$

Convert to minutes

Multiply by 60

$2.25\ h=2.25(60)=135\ minutes$

Determine the value of a, b, and c for the quadratic equation: 4x2- 8x = 3

Rufina [12.5K]

Answer:

B. a = 4, b = -8, c = -3

Step-by-step explanation:

The quadratic equation given is:

$4x^2- 8x = 3$

The general form of a quadratic equation is given as:

$ax^2 + bx +c = 0$

Let us put the given equation in this form and then compare with the general form of the quadratic equation.

$4x^2- 8x = 3\\\\4x^2 - 8x - 3 = 0$

Therefore, by comparing:

a = 4

b = -8

c = -3

The correct option is B

Your test scores for the semester are 87,84 and 85.Can you raise your test average to 90 with you next test?

Rainbow [258]

Answer:

Yes

Step-by-step explanation:

If you add 87.84, 85, and 100 you get 272.84. Once you divide that by 3 you get 90.946, which would be your test average if you score 100 on your next test.
