Answer:

0.04 h

Step-by-step explanation:

The given equation is :

8h=200

It is used to find hours h a person needs to work to earn $200 at $8 per hour.

We need to find no of hours does a person need to work to earn $200. It can be calculated as follows :

\dfrac{8h}{200}=\dfrac{200}{200}\\\\h = 0.04\ h

So, for $200, the person will need 0.04 h.

A 5.00 L air sample has a pressure of 107 kPa at a temperature of -50C. If the temperature is raised to 102C and the volume expa
joja [24]

Answer:

129.9 kPa

Step-by-step explanation:

The relationship between temperature T, volume V and pressure P is given by the ideal gas equation which is given as

K = PV/T where K is a constant such that were there is a change of temperature T₁, volume V₁ and pressure P₁ to  temperature T₂, volume V₂ and pressure P₂ then the relationship may be given

P₁V₁/T₁ = P₂V₂/T₂

where T is measured in ⁰K

T₁ = -50 + 273

= 223 ⁰K

T₂ = 102 + 273

= 379 ⁰K

5 × 107/223  = P₂ × 7/379

P₂ = 129.9 kPa

Please help with this MATH question. I would appreciate it, it is the only one I need help with. SOLVING A SYSTEM INCLUDING LINE
makkiz [27]

Answer:

see below and attached

Step-by-step explanation:

To solve a system of quadratic equations:

  • Equal the equations then rearrange so that it is set to zero.
  • Use the quadratic formula to solve.

I have done this (see attached workings) but cannot get any of the solutions you've provided.  I have even graphed the two functions, and the points of intersection concur with my workings (see attached graph).

Solutions to -8x + 5 less than or equal to 11
Vilka [71]

Answer:

x\geq -\frac{3}{4}

Step-by-step explanation:

-8x+5\leq 11\\\\1. -8x\leq 11-5\\   -8x\leq 6

Isolate the parts of the equation with the x variable

2. \frac{-8}{-8} x\geq\frac{6}{-8}  \\x\geq -\frac{3}{4}

When you divide or multiply by a negative number in inequalities, you must flip the sign of the inequality.
