Answer:

£16.20

Step-by-step explanation:

If F is litres of fruit juice, and L is litres of lemonade, then we can write a proportion:

F / L = 1 / 3

Cross multiply:

L = 3F

The total volume is 16 litres, so:

F + L = 16

Substitute and solve:

F + 3F = 16

4F = 16

F = 4

L = 12

There are 4 litres of fruit juice and 12 litres of lemonade.

The total cost is:

C = 1.80 F + 0.75 L

C = 1.80 (4) + 0.75 (12)

C = 16.2

The cost is £16.20.

Which graph shows the solution to the system of equations? Solve the system graphically. Click on the graph until the correct so
romanna [79]
The correct answer is:  "Graph [D]:  "the fourth graph provided".
__________________________________________________
Explanation:  By looking at each graph in each of the 4 (FOUR) answer choices provided;   "Graph [D]" (the fourth answer choice) is the only graph in which two (2) of the same lines intersect at the same point with the particular coordinates: 
  "(6, -2)" ;  that are correct for BOTH of the 2 equations given.
Furthermore, we see that the coordinates for BOTH of the x and y- intercepts for BOTH of the equations given in this problem—are, in fact, points along EACH of the given corresponding 2 (two) corresponding lines in:  "Graph [D]".

What is the measurement of the indicated central angle. 6 pi. R=15
goldenfox [79]

Answer:

r=12

Step-by-step explanation:

r=12

circumference of arc = theta/360*2πr=3π given

Pi cancels

theta/360*2*12=3

theta*6/90=3

theta*3/45=3

3 cancels,45 to the other side

theta=45 degrees

This should do it :)
