How do I substract 7/10 minus 3/15
Bond [772]

Answer: 0.5

Step-by-step explanation:

To reduce a fraction: divide the numerator and denominator by their greatest common factor, GCF.

Fraction: 7/10 already reduced to the lowest terms.

The numerator and denominator have no common prime factors.

Their prime factorization:

7 is a prime number;

10 = 2 × 5;

gcf (7; 2 × 5) = 1;

Find sin 0, where 0 is the angle shown.<br> Give an exact value, not a decimal approximation.
faust18 [17]

Answer:

Answer: Sin0 = 8/8.5

Step-by-step explanation:

Step-by-step explanation: What we have is a right angled triangle, with two sides given and one angle which is the reference angle (unknown angle).

The Sine of the angle is calculated as

Sin0 = opposite/hypotenuse

We have the opposite side (facing the reference angle) as 8 units and the hypotenuse (facing the right angle unknown), which we shall label as X.

To calculate the hypotenuse, we shall apply the Pythagoras theorem which is,

X² = 3² + 8²

X² = 9 + 64

X² = 73

Adding the square root sign to both sides of the equation, we now have

X = √73

X = 8.5 (approximately)

Now that we have the hypotenuse as 8.5, the Sine of the angle can now be calculated as

Sin0 = opposite/hypotenuse

Sin0 = 8/8.5

A bag contains 6 red balls and 9 black balls. Two balls are drawn, one after the other with replacement. Find the probability th
patriot [66]

Answer:

a) 13/25

b) 12/15

Step-by-step explanation:

a) Since it is with replacement, the chance of them being both the same colour will be

P(both red) + P(both black) = (6/15*6/15) + (9/15*9/15)

                                              = 13/25

b) If they are both different colours, then we will be working out

P(both colours) = (6/15*9/15)*2 = 12/25   (Its *2 because the other way of pulling both colours is 9/15*6/15 which is the same but flipped)

Another way of working this question out is

P(1-All red or all blue) which from above we know that All red or all blue is 13/25 so

P(1-All red or all blue) = 1 - 13/25 = 12/25
