4 0

Answer:

2/5

1/6

1/10

Step-by-step explanation:

total number of cubes = 12 + 5 + 3 = 20

Probability of picking green cubes = total number of green cubes / total number of cubes = 12/30 = 2/5

Probability of picking blue cubes = total number of blue cubes / total number of cubes = 5/30 = 1/6

Probability of picking yellow cubes = total number of yellow cubes / total number of cubes =  3/30 = 1/10

Which of these sugar syrup will be the sweetest ? The sugar syrup with,Required to answer. Single choice.Immersive Reader (1 Poi
aleksley [76]

Answer:  c. 150g of sugar dissolved in 300ml water

Step-by-step explanation:

The concentration of sugar syrup will decide which syrup is sweetest. Concentration is defined as the amount of solute dissolved per unit volume of solution.

a) 50g of sugar dissolved in 150ml water

Concentration=\frac{50g}{150ml}=0.33g/ml

b) 100g of sugar dissolved in 500ml water

Concentration=\frac{100g}{500ml}=0.2g/ml

c)  150g of sugar dissolved in 300ml water

Concentration=\frac{150g}{300ml}=0.5g/ml

d) 250g of sugar dissolved in 1000ml water

Concentration=\frac{250g}{1000ml}=0.25g/ml

Thus 150 g of sugar dissolved in 300ml water has highest concentration and is sweetest.

Assume that the radius of the circle is 1.


The diagonal of the square is 2. By the Pythagorean Theorem, the side of the square of a right triangle will be 2/sqrt(2).


Finally, the ratio of the square to the circle, in area, will be


(2/sqrt(2))^2 : pi*(1)^2 = 2 : pi


We can conclude that the white area is about 35%.

What is the equation of the line with an x-intercept of -1 and a y-intercept of 2?
iragen [17]

Answer:

y = 2x + 2

Step-by-step explanation:

The general form

is;

y = mx + b

where m is the slope and b is the y-intercept

so we have;

y = mx + 2

To get m, substitute the point (-1,0)

So we have

0 = -m + 2

m = 2

So the equation is;

y = 2x + 2
