8. P₁V₁ = P₂V₂ T₁ T₂ Rewrite this expression to find T₂.

vitfil [10]

Answer:

$T_{2} = \frac{P_{2} V_{2} T_{1}} {P_{1} V_{1}}$

Step-by-step explanation:

The Combined Gas Law expression is:

P₁V₁ / T₁ = P₂V₂ / T₂

To solve for T₂, you need to.....

$\frac{P_{1} V_{1} }{T_{1} } = \frac{P_{2} V_{2} }{T_{2} }$ <------ Original expression

$\frac{T_{2} P_{1} V_{1} }{T_{1} } = {P_{2} V_{2} }$ <----- Multiply both sides by T₂

${T_{2} P_{1} V_{1} } = {P_{2} V_{2} T_{1}}$ <----- Multiply both sides by T₁

$T_{2} = \frac{P_{2} V_{2} T_{1}} {P_{1} V_{1}}$ <----- Divide both sides by P₁V₁

Luisa earns money mowing her neighbors' lawns.

Irina-Kira [14]

Answer:

$p(x)=16x-25$

C is the correct option.

Step-by-step explanation:

We have been given that

$r(x)=20x\\c(x)=4x+25$

The profit is the difference of revenue and cost function.

Mathematically, we can write profit function as

$p(x)=(r-c)x$

We know that $(f-g)(x)=f(x)-g(x)$ . Thus, we have

$p(x)=r(x)-c(x)$

Plugging, the r(x) and c(x) functions

$p(x)=20x-(4x+25)$

Distribute negative over the parenthesis

$p(x)=20x-4x-25$

Combine the like terms. 20x-4x = 16x

$p(x)=16x-25$

C is the correct option.

tatyana61 [14]

Answer:

Quincy

Step-by-step explanation:

Each student is assigned a two digit number, so let's split the random number line into two digit numbers:

59, 78, 44, 43, 12, 15, 95, 40, 92, 33, 00, 04, 67, 43, 18, 02, 61, 05, 73, 96, 16, 84, 33, 84, 54

Now let's identify the numbers between 00 and 29.

59, 78, 44, 43, 12, 15, 95, 40, 92, 33, 00, 04, 67, 43, 18, 02, 61, 05, 73, 96, 16, 84, 33, 84, 54

So the fifth student in the list is #18, or Quincy.
