taurus [48]

Answer:

$ 0.8.

Step-by-step explanation:

1) if to assume, 'c' - price of the coffee and 'd' - price of the doughnuts, then

2) it is possible to write the equation 1 (when five MinB enter): 3d+5c=3.3;

3) it is possible to write the equation 2 (when three aliens entered): 4d+3c=2.75;

$4) \ \left \{ {{3d+5c=3.3} \atop {4d+3c=2.75}} \right. \ = > \ \left \{ {{c=0.45} \atop {d=0.35}} \right.$

5) if c=0.45 and d=0.35, then Ag.Z. paid 0.35+0.45=$ 0.8.

One shape is approaching a poor from the east traveling west at 15 mph and its presently 3 miles east east of the port I second

valentinak56 [21]

Answer:

DL/dt = 17 mph

Step-by-step explanation:

The ships and the port shape a right triangle

Ship going west ( x-direction) is traveling at 15 mph

Ship going north (y-direction) is traveling at 10 mph

The distance L between ships is:

L² = x² + y²

Tacking derivatives on both sides of the equation with respect to time

we get

2*L*DL/dt = 2*x*Dx/dt + 2*y*Dy/dt (1)

In that equation we know:

Dx/dt = 15 mph

Dy/dt = 10 mph

At the moment ship traveling from the east is at 3 miles from the port

then x = 3 m and the other ship is at 4 miles north

then by Pythagoras theorem

L = √ 3² + 4² L = 5

By substitution in equation 1

2*5*DL/dt = 2*3*15 + 2*4*10

10* DL/dt = 90 + 80

DL/dt = 170 / 10

DL/dt = 17 mph

Adam, Brian, and Christine order two small pizzas. Adam eats three quarters of a pizza, Brian eats one third of a pizza, and Chr

vampirchik [111]

<h3>Answer: 11/12</h3>

============================================================

Explanation:

3/4 = 9/12 after multiplying top and bottom by 3

1/3 = 4/12 after multiplying top and bottom by 4

When combining the fractions 3/4 and 1/3, we get,

3/4 + 1/3 = 9/12 + 4/12 = (9+4)/12 = 13/12

Let's convert that result into a mixed number

13/12 = (12+1)/12

13/12 = 12/12 + 1/12

13/12 = 1 + 1/12

13/12 = 1 & 1/12

Adam and Brian have collectively eaten 1 full pizza plus an additional 1/12 of the second pizza. This leaves 11/12 of the second pizza for Christine to eat. Notice how the fractions part 1/12 and 11/12 add to 12/12 = 1.

Check out the diagram below.
