Answer:

$37.50

Step-by-step explanation:

2 necklaces for $15.00 = $30.00

Plus the $7.50 for the third necklace ($7.50 is half of $15 which is what each necklace costs)

Add it all together:

$30 + $7.50 = $37.50

2(15.00) =30

15.00/2 = 7.5

30+7.5 = $37.5

Answer is $37.5

D(5, 7), E(4, 3), and F(8, 2) form the vertices of a triangle. What is m∠DEF?

lakkis [162]

DE^2 = 1 + 16 = 17.
EF^2 = 16 + 1 = 17. 
DF^2 = 9 + 25 = 34. 
Since (DE)^2 + (EF)^2 = (DF)^2,
 angle E is 90 degrees.
 DF must be the hypotenuse

A tank contains 250 liters of fluid in which 40 grams of salt is dissolved. Brine containing 1 gram of salt per liter is then pu

VashaNatasha [74]

Answer:

$A(t)=250-210e^{-\frac{t}{50}}$

Step-by-step explanation:

We are given that

Volume,V=250 L

Mass of salt=m=40 g

Brine containing 1 g per liter

Pumped into the tank at the rate=5 L/min

We have to find the number A(t) of grams of salt in the tank at time t.

Rate of change of salt in the tank

$\frac{dA}{dt}=$ Rate in-Rate out

Rate in=5 L/min

Rate out= $\frac{A}{250}\times 5=\frac{A}{50}$ L/min

$\frac{dA}{dt}=5-\frac{A}{50}=\frac{250-A}{50}$

$\int \frac{50dA}{250-A}=\int dt$

$-50ln(250-A)=t+C$

Using the formula

$\int \frac{dx}{x}=ln x$

A=40 and t=0

$-50ln(250-40)=0+C$

$-50ln(210)=C$

Substitute the value

$-50ln(250-A)=t-50ln(210)$

$-50ln(250-A)+50ln(210)=t$

$50ln\frac{210}{250-A}=t$

$t=50ln\frac{210}{250-A}$

$\frac{t}{50}=ln\frac{210}{250-A}$

$\frac{210}{250-A}=e^{\frac{t}{50}$

$\frac{250-A}{210}=e^{-\frac{t}{50}}$

$250-A=210e^{-\frac{t}{50}}$

$A(t)=250-210e^{-\frac{t}{50}}$

Find The Slope (-4, 6) and (-2,1)

Anika [276]

Answer:

-5/-6

Step-by-step explanation:

Use the equation rise over run, which is also y2-y1 over x2-x1

in basically every type of thing, x always comes first then y

y2=1 y1=6 x2=-2 x1=-4

1-6/-2-(-4)=-5/-6, because it was changed to, -5/-2+4
