Answer:

Step-by-step explanation:

we are given that given that  1/2T = 60 so T=120°  so we also know R = 120 °

then W and S are also the same angle so 2z +240 = 360

2z = 120

z=60

W =60 °

S = 60 °

which makes sense b/c the small triangles also tell us that the sharp angles of the small triangles are 30 °  for the  30 , 60 90 triangle.

so by complementary angle we know that c = 60 °

we also know that a = 12 b/c all the small triangles are identical.  

we also know that b= 90 °  also by complementary angle

we can also solve for length of SW and RT

cos(30)=adj / Hyp  

12*Cos(30) = adj

12*\sqrt{3} /2 = adj

but the adjacent side is 2 times for SW so

SW = 12 \sqrt{3}

for RT

sin(30) = Opp / hyp

12 * Sin(30) = Opp

12 * 1/2 = opp

but RT is times 2 again, sooo

RT = 12

you can also solve for the area of SRWT = 12 *12 = 144 units  (what ever unties 12 is in)   hmmm

That's all I can think of to solve for now  :)

What is the value of 9P5 ?
zalisa [80]
\bf _nP_r=\cfrac{n!}{(n-r)!}\qquad \qquad \qquad _9P_5=\cfrac{9!}{(9-5)!}

check your calculator for the [!] factorial button.

also bear in mind that most calculators also have an [ₙPᵣ] button, to get Permuations, and you can just use that.

Suppose that a large mixing tank initially holds 100 gallons of water in which 50 pounds of salt have been dissolved. Another br
Serggg [28]

Answer:

dA/dt = 12 - 2A/(100 + t)

Step-by-step explanation:

The differential equation of this problem is;

dA/dt = R_in - R_out

Where;

R_in is the rate at which salt enters

R_out is the rate at which salt exits

R_in = (concentration of salt in inflow) × (input rate of brine)

We are given;

Concentration of salt in inflow = 4 lb/gal

Input rate of brine = 3 gal/min

Thus;

R_in = 4 × 3 = 12 lb/min

Due to the fact that solution is pumped out at a slower rate, thus it is accumulating at the rate of (3 - 2)gal/min = 1 gal/min

So, after t minutes, there will be (100 + t) gallons in the tank

Therefore;

R_out = (concentration of salt in outflow) × (output rate of brine)

R_out = [A(t)/(100 + t)]lb/gal × 2 gal/min

R_out = 2A(t)/(100 + t) lb/min

So, we substitute the values of R_in and R_out into the Differential equation to get;

dA/dt = 12 - 2A(t)/(100 + t)

Since we are to use A foe A(t), thus the Differential equation is now;

dA/dt = 12 - 2A/(100 + t)

A 16-ounce bottle of orange juice says that it contains 200 milligrams of vitamin C, which is 250% of the daily recommended dosa
Andrei [34K]

80 milligrams is the amount of vitamin C that is considered to be 100% of the daily recommended requirement for adults.

<h3>What is the daily recommended dosage of vitamin C for adults? </h3>

Parameter

  • The amount of liquid included in the bottle is 16 ounces.
  • The vitamin C content of the bottle comes to a total of 200 milligrams.

Since the orange juice container that has a capacity of 16 ounces states that it has 200 milligrams of vitamin C, this means that it fulfills 250% of an adult's recommended daily requirement for vitamin C. Then, for one hundred percent of the daily allotment,

As a result, we are able to draw the conclusion that the amount of vitamin C that is considered to be 100% of the daily recommended requirement for people is 80 milligrams.
