Answer:

1/5

Step-by-step explanation:

Since we have given that

Quantity of orange juice = 30 ml

Quantity of apple juice = 20 ml

Quantity of coconut juice = 50 ml

Total quantity of cocktail = 100 ml

So, the ratio of orange juice to apple juice to coconut juice is given by

=30:20:50

= 3:2:5

Total ratio=3+2+5

=10

So, proportion of the cocktail of apple juice is given by

2/10×100

=1/5×100

=20%

Hence, the proportion of the cocktail is 1/5 apple juice

THE DIFFERENCE OF TWO NUMBERS IS 4 AND THEIR SUM IS -7. WHAT IS THEIR PRODUCT. Who ever solved this correct will mark brainlist.
babunello [35]

Answer:

33/4

Step-by-step explanation:

Let the first number be x, and the second number be y.

x - y = 4

x + y = -7

Solve for x in the first equation.

x - y = 4

x = 4 + y

Put x as (4 + y) in the second equation and solve for y.

4 + y + y = -7

4 + 2y = -7

2y = -7 - 4

2y = -11

y = -11/2

Put y as -11/2 in the first equation and solve for x.

x - y = 4

x - (-11/2) = 4

x + 11/2 = 4

x = 4 - 11/2

x = -3/2

Their product is:

-11/2 × -3/2

33/4

I'm not sure if it only wants you to find Equation 1 or go further and solve:

x = the number of 5c coins

y = the number of 10c coins

Equation 1: the total number of coins is 65

x + y = 65

total value of $3.80

0.05x + 0.1y = 3.8

<u>Simultaneous Equations</u>

Make one coefficient the same

10 * (0.05x + 0.1y = 3.80 = 0.5x + y = 38

x + y = 65

0.5x + y = 38

Subtract the equations

(x + y) - (0.5x + y)= 65 - 38

(x - 0.5x) + (y - y) = 65 - 38

0.5x = 27

x = 54

Substitute it into the original equation to find y.

x + y = 65

54 + y = 56

y = 65 - 54 = 11

Substitute it into the other equation to check it's right.

0.05x + 0.1y = 3.8

0.05(54) + 0.1(65) = 3.8

x = 54 5c coins

y = 11 10c coins
