Answer:

Option C is correct.

Step-by-step explanation:

C. Buying a hammer and buying nails are dependent events. - This is correct.

Two events are said to be dependent on each other, if the occurrence of the first event affects the occurrence of the second event thus changing the probability. Here the probability for both the events is 0.10\times0.40=0.04

Factorize this fully 20x² +500x+3000​
Serga [27]

Answer:

20(x+15)(x+10)

Step-by-step explanation:

Hi there!

As your question states, we need to fully factor the polynomial: 20x²+500x+3000

These are pretty big numbers; let's pull out the GCF, as that will make it easier to factor

the GCF is 20

so factoring 20 out of the polynomial will get:

20(x²+25x+150)

As you can see, the polynomial inside the parenthesis is a lot easier to factor than the original with really big numbers.

Now use FOIL to factor x²+25x+150 into 2 binomials

25 is the sum of the last terms

150 is the product of the last terms

think: which two numbers add up to 25 but multiply to get 150?

those two numbers are 15 and 10

x²+25x+150 factored is (x+15)(x+10)

but remember we have the 20 in front of x²+25x+150  (or now, (x+15)(x+10))

therefore the fully factored binomial is 20(x+15)(x+10)

Hope this helps! :)

Hello I really needs some help this is algebra
Levart [38]

Answer:

x = 5

Step-by-step explanation:

5 - 3x = - 10

<em>Subtract 5 from both sides:</em>

5 - 5 - 3x = -10 - 5

-3x = -15

<em>Divide -3 by both sides:</em>

-3x/-3 = -15/-3

x = 5

hope this helps!! p.s. i really need brainliest :)

Find the height of the triangle by applying formulas for the area of a triangle and your knowledge about triangles.
neonofarm [45]

Using the Pythagorean Theorem, the altitude to side c has a length of 11.3 inches.

<h3>What is the Pythagorean Theorem?</h3>

The Pythagorean Theorem relates the length of the legs l_1 and l_2 of a right triangle with the length of the hypotenuse h, according to the following equation:

h^2 = l_1^2 + l_2^2

To find the altitude relative to side c, we bisect this side, which cuts it's length into half(now of 4 inches), forming a right triangle in which:

  • The altitude is the other leg.
  • The side of 12 inches is the hypotenuse.

Hence:

x^2 + 4^2 = 12^2

x = \sqrt{12^2 - 4^2}

x = 11.3 inches.
