7. a tank with volume 100 m3 is filled mass of salt in the an infow pipe carries a salt solution with concentration 2 of 4 m3/min. the solution in the tank is well-mixed by a pair of swimming mermaids wtw pipe carries thue note to chemical engineers: that's how they really do it at chemical processing emired solution out of the tank at the rate of 4 m3/in. set up and solve the initial value problem to ind the with a salt solution with concentration 0.56 kg/m (hint: what is the initial kg/m3 into the tank at the rale ts). an outflow pipe car mass s(t) (kg) of salt in the tank at time t. 10 pts

john got lost so he didn't know what to do and it was crazy because he didn't except it

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
