Find the value of x and m∠HKL.

Answers

Answer:

x = 25 degrees ∠HKL = 102 degrees

Step-by-step explanation:

The whole thing equals 180, since it is a straight angle

The value of HKL is 180 - 78 = 102

So that means 4x + 2 = 102

Subtract 2 from both sides:

4x = 100

Divide both sides by 4:

x = 25

6x^2 - 18x - 240 = 0
solve for x.
Find solutions that are greatest to least.

Answers

6x^2 -18x -240=0 is a quadratic equation. Therefore you can use the quadratic formula to find ‘x’.

The greatest solution will be 8 and least solution will be -5.

A polynomial equation is given which is 6x² - 18x - 240 = 0

We have to find out the solutions that are greatest to least.

What do you mean by the quadratic equation ?

Quadratic equation is a polynomial equation whose highest degree is two . It is expressed in the form of ax² + bx + c = 0.

As per the question ;

Equation is ;

6x² - 18x - 240 = 0

Let's take 6 as common ;

6 ( x² - 3x - 40 ) = 0

x² - 3x - 40 = 0

This can be written as ;

x² - 8x + 5x - 40 = 0

x ( x - 8 ) + 5 ( x - 8 ) = 0

( x + 5 ) ( x - 8 ) = 0

x + 5 = 0

and

x - 8 = 0

So ;

x = - 5 and 8

Thus , the greatest solution will be 8 and least solution will be -5.

What is the result when 3/8x + 2 1/5 is subtracted from 3 1/2x - 4 1/10?

Don’t put a link.

Answers

Answer:

Option 3 3 1/8x - 6 3/10

Step-by-step explanation:

(3 1/2x - 4 1/10) - (3/8x + 2 1/5)

Divide it into parts:

(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)

3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x

-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10

So we get:

2 1/4x - 6 3/10

Based on your data, what is the experimental probability that the family has two dogs or two cats? (Heads= dogs and tails=cats)

My table:

Heads, Heads
15
Heads, Tails
9
Tails, Heads
16
Tails, Tails
10
Total
50
Also, please explain your answer.

Answers

Answer:

Two dogs: 30%

Two cats: 20%

Two dogs OR two cats: 50%

Step-by-step explanation:

Since the total is 50, we have to multiply all the numbers by two. The total will then 100, so one unit in each category will represent one percent. For example, 15 x 2 = 30, so the chance for two dogs is 30%.

If your question meant two dogs OR two cats as a single probability - not the individual probabilities of two dogs and two cat - then it is 50%, because 30 (two dogs) + 20 (two cats) = 50 (two dogs OR cats). I hope this helps! Sorry if my explanation doesn’t make lots of sense, I’m typing this off my phone. Feel free to ask any questions!
