Answer:
10x² - 13x - 3

Step-by-step explanation:
(2x - 3) (5x + 1)

Apply distributive property ,

= 2x(5x + 1) - 3(5x + 1)
= 10x² + 2x - 15x - 3
= 10x² - 13x - 3

A device is rated at 1,100 watts.what current is required if it is operated at 110 volts?​
WINSTONCH [101]

1 ) Watts =E * I = 110 * 5 = 550 watts =.55 KW  

2) I = Watts / e = 1100 / 110 = 10 amperes  

3) 1 horsepower = 33000 ft/lbs per minute  

HP = ( 2000 * 1000) / (33000 *4) = 15.1515 hp  

4) cost = (10 * 100 / 1000) *11 * $0.10 = $1.10  

5) This answer will be incorrect because you have not stated the power factor of the motor.  

va = I * E = 7.5 * 240 = 1800  

2 hp = 2 * 746 watts = 1492 watts  

If the motor had a 1.0 power factor (it doesn't) the efficiency would be  

efficiency = output / input = 1492 / 1800 = 82.888 %  

6) I = watts / E =1000 / 120 = 8.333 amps  

7) 1 = watts / E = 1000 / 240 = 4.1616  

8) Kw-hr = (2 * 24 * 365 ) / 1000 = 17.52  

cost = kw-hr * $0.03 = 17.52 * $0.03 = $0.5256  

9) efficiency = (115 * 240) / (2400 * 12) = 95.8333 %  

10) KW = (I^2 * R) / 1000 = (20^2 * 5) / 1000 = 2

Lauren is working two summer jobs Lifeguarding and washing cars .She can work no more then 9 hours Altogether between both jobs
Mkey [24]

Answer:

L + W \leq 9

Step-by-step explanation:

Given

Represent lifeguarding cars with L

Represent washing cars with W

Hours = 9\ hours --- at most

Required

Express the scenario as an inequality

First, we need to determine the number of hours Lauren can work.

This is calculated as follows:

Total\ Hours = L + W

From the question, we understand that the total hours cannot exceed 9 hours.

This can be expressed as \leq 9

So, we have:

Total\ Hours \leq 9

Substitute L + W for Total Hours

L + W \leq 9

Understanding the Pythagorean Theorem – Finding an Unknown Hypotenuse (find the distance of the mechanical webbing needed by Spi
barxatty [35]

Answer:

100√65 yds

Step-by-step explanation:

The Pythagorean Theorem is a^2+b^2=c^2. In this case a=700, b=400, and c is the unknown.

  • 700^2+400^2=c^2
  • 490000+160000=c^2
  • 650000=c^2
  • c=√650000

√650000=√(100^2•65)=100√65
