Answer:39 hours
Step-by-step explanation:First, let's find the rate of money per hour:$554.30 / 23 hour= $24.1 / 1 hourDaniel earns $24.10 every hour he works.To find the hours that Daniel has to work to earn $939.90, divide it by 24.10:$939.90 / 24.10= 39Now, we can check:$24.10 * 39= $939.90
Answer:
813 N/m²
Step-by-step explanation:
The units of pressure tell you it is found by dividing force by area. Here, we need to convert the units of the given area so we can express the pressure appropriately.
__
pressure = force / area
pressure = (61 N)/(750 cm² × ((1 m)/(100 cm))²) = (61 N)/(0.0750 m²)
pressure ≈ 813 N/m²
It is a cubic function that is down up (the direction of the ends) and has roots at (figure out the roots either 1/2/3)
James must mix 60 millilitres of 10% solution and 40 millilitres of 50% solution.
Given that, James needs to mix a 10% acid solution with a 50% acid solution to create 100 millilitres of a 26% solution.
Let the acid solution needs to mix with 10% be <em>x</em> ml and the acid solution needs to mix with 50% will be 100 - <em>x</em> ml.
Now,
10% x + 50% ( 100 - <em>x</em> ) = 26% ×100
⇒
⇒10<em>x</em> + 50( 100 - <em>x</em> ) = 2600
⇒10 <em>x</em> + 5000 - 50<em>x</em> = 2600
⇒10 <em>x</em> - 50 <em>x</em> = 2600-5000
⇒-40 <em>x</em> = -2400
⇒<em>x</em>=60
Therefore, James must mix 60 millilitres of 10% solution and 40 millilitres of 50% solution.
