Mathematics
1 answer:

Answer:

the answer would be c

Step-by-step explanation: Because the values inside of the parenthesis don't have the same variable, they cannot be combined. Using the 9 on the outside of the parenthesis you would multiply 9 by 3r, which gives you 27r, and 9 by -4 to create -36. The new equation would be 27r - 36, which is equivalent to the equation shown next to it.

If a,b,c are in arithmetic sequence then a = ...​
andriy [413]

Answer:

If a, b and c are in arithmetic progression, that means that a + c = 2b. So a + b, a + c and b + c are also in arithmetic progression.

This might help.

Hey can you please help me posted picture of question

Total number of chips = 4+ 6 = 10
Number of white chips = 4

Probability of picking a white chip = \frac{4}{10}= \frac{2}{5}

This white chip is not replaced back into the bag. This will reduce the number of white chips in the bag by 1 and reduce the total number of chips in the bag by 1.

So, now the total number of chips in the bag = 3 + 6 = 9
Number of white chips in the bag = 3

Probability of picking a white chip = \frac{3}{9}= \frac{1}{3}

Thus, the probability of picking two white chips will be = \frac{2}{5}* \frac{1}{3}= \frac{2}{15}

Therefore, option B gives the correct answer.

If the length of one leg of a right triangle is 3 and the hypotenuse is √34, what is the length of the other leg?
Elenna [48]

To answer this question you must use Pythagorean theorem

a^{2} +b^{2}=c^{2}

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 3

b = unknown

c = √34

^^^Plug these numbers into the theorem

3^{2} +b^{2} =√34^{2}

Simplify

9 + b² = 34

solve for b

b^{2} = 25

Take the square root of both sides to cancel out the square from the b

√b² = √25

b = 5

Hope this helped!
