This will be easy if you start by adding both unit at the left side {12+41=53} and on the right side {31+n=53}
answear= 22

106 people I think. because 12×n is 12n And 31×41 Is 1271 then take 12n ÷1271 Is 105.96... then rounded to the nearest person is 106

Persons A and B are at the beach, their eyes are 5 ft and 6 ft, respectively, above sea level. How many miles farther out is Per

Marysya12 [62]

Answer:

The radius of the earth is something like 4000 miles= about 20,000,000 feet. (Look up the exact radius of the earth to calculate the correct number yourself, I'm too lazy!)

The horizon is where you're looking at a tangent to the earth's surface. Since the tangent to a circle is perpendicular to the radius (if we assume the earth is a perfect sphere), we can set up a right angled triangle:

H...P

Where C is the centre of the earth, H is the horizon, and P is the person. CH = 20,000,000 feet. CP = 20,000,005 feet (in the case of the 5' person, that'd be me :) And there is a right angle at H.

So using Pythagoras' theorem, if d = PH, then:

d^2 = 20,000,005^2 - 20,000,000^2

=> d^2 = 200,000,025

=> d = 14142 feet (just under 3 miles)

For a 6' person:

d^2 = 20,000,006^2 - 20,000,000^2

=> d^2 = 240,000,036

=> d = 15491 feet

So the difference is 1349 feet or 0.256 miles

Repeat this exercise with the real radius of the earth (in feet) to get the correct answer, but it'll be pretty close to what I've given here

A plumber charges $50 for a service call plus $80 per hour. If she spends no longer than 8 hours a day at any one site, find a l

Paha777 [63]

Answer:

$C(t)=80t+50, \text{ for }t\leq 8$ .

Step-by-step explanation:

Let C represent total daily charges in dollars and t represent time in hours.

We have been given that a plumber charges $50 for a service call plus $80 per hour.

The amount charged for t hours would be $80t$ .

The total amount charged for t hours would be $C(t)=80t+50$ .

We are also told that plumber spends no longer than 8 hours a day at any one site, this means that time t have a restriction as:

$t\leq 8$

Therefore, our required cost function would be $C(t)=80t+50, \text{ for }t\leq 8$ .

A tank contains 50 gallons of water in which 2 pounds of salt is dissolved. A brine solution containing 1.5 pounds of salt per g

Bond [772]

Answer:

A(0) = 2; A'(t) = 6 - 0.08A(t)
A(∞) = 75

Step-by-step explanation:

The initial value is said to be 2 pounds, so A(0) = 2.

The influx is (1.5 #/gal)×(4 gal/min) = 6.0 #/min.

The outflow is (4 gal)/(50 gal) × A(t) = 0.08A(t).

The rate of change of A(t) is then ...

A'(t) = 6 - 0.08A(t)

When the system reaches steady state, A'(t) = 0, so ...

0 = 6 - 0.08A(∞)

A(∞) = 6/0.08 = 75

75 pounds of salt will be in the tank after a long period.
