Answer:

13064 feet

Step-by-step explanation:

We can rewrite the formula so that x is in feet. Equating the new formula to 8.743 PSI, we have ...

8.743 = 14.7e^(-0.21x/5280)

Dividing by 14.7 and taking natural logs, we have ...

ln(8.743/14.7) = -0.21x/5280

Multiplying by the inverse of the coefficient of x gives ...

x = 5280·ln(8.743/14.7)/-0.21 ≈ 13064.0806

I think it’s 8/55=4/x
So it’s 8x=4(55)
8x=220
x=220/8
x=27.5

Rob can lift less than 135 pounds at the weight room. There is already 48 pounds of weights on the bar. Write an inequality that

Rama09 [41]

Answer:

$x + 46 < 135$

Step-by-step explanation:

Given

$Initial\ Weight = 48lb$

He can lift less than 135 implies that, his maximum is:

$Total < 135$

Required

Determine the additional weight

Let the additional weight be x

Such that

$Total = x + Initial\ Weight$

$Total = x + 46$

Substitute x + 46 for Total in $Total < 135$

$x + 46 < 135$

Hence, the inequality that describes the scenario is: $x + 46 < 135$

A water tank has 1,500 liters of water. It has a leak, losing 4 liters per minute. At the same time, a second tank has 300 liter

Darina [25.2K]

Let $t$ be the number of minutes.

The first tank starts with 1500 liters, and loses 4 liters per minute, so after $t$ minutes there will be

$1500-4t$

liters of water.

The second tank is filled at 6 liters per second, i.e.

$6\times 60=360$ liters per minute.

So, there will be

$300+360t$

liters of water in the second tank after $t$ minutes.

The two quantities will be equal when

$1500-4t=300+360t \iff 1200=364t \iff t=\dfrac{1200}{364}\approx 3.3$

so, approximately, after 3.3 minutes.
