sean earns 4.50 per hour more than the trainee during one 8 hour day they earn a total of $284 how much does Sean make per hour

1 answer:

3 0

1) Let Sean=x and Tyrone=y. But we want to get what Sean earns and what Tyrone earns in terms of one variable so we say that Tyrone=x-4.5 (beacuse he makes $4.50 per hour less than Sean). 2) Now set up the equation: 8 hours time x plus 8 hours times x-4.5 equals 284 OR
8x+8(x-4.5)=284 3) Solve for x 8x+8(x-4.5)=284 8x+8x-36=284 16x=320 x=20 So Sean makes $20 per hour and Tyrone makes $15.50 per hour

300 ml over 15 min is what rate of ml per hour

Mama L [17]

Answer:

1200 ml per hour

Step-by-step explanation:

To compute what rate is 300 ml over 15 mins as a rate of ml per hour, we do a rule of 3, using a variable x as that amount of ml we don't know yet. We should have everything in the same units, so instead of writing 1 hour we write 60 minutes:

$\frac{300~ml}{15~min}=\frac{x~ml}{60~mins}$

Now we solve for x:

$\frac{300~ml}{15~min}\cdot 60~mins=x~ml$

$\frac{18000~ml}{15} =x~ml$

$1200~ml =x~ml$

And so, now that we know the value of x, the rate we wanted to find is

$\frac{1200~ml}{60~mins}$

Which is just 1200 ml per hour.

Sonji correctly added 2p+1/p-8 and 3p-3/4p and got 8p^2+4p+3p-27p+24/(p-8)(4p). What is the simplified sum?

RUDIKE [14]

Answer:

The simplified sum is $\frac{11p^{2}-23p+24}{(p-8)4p}$

Step-by-step explanation:

we have

$\frac{2p+1}{p-8}+\frac{3p-3}{4p}=\frac{4p(2p+1)+(p-8)(3p-3)}{(p-8)4p}\\ \\=\frac{8p^{2}+4p+3p^{2}-3p-24p+24}{(p-8)4p}\\ \\ =\frac{11p^{2}-23p+24}{(p-8)4p}$
