Answer 2

The solution to the given equation is 5 and -6.

What is solution of equation?

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

[tex]\sqrt{x^{2} +2x-25} = \sqrt{x+5}\\ \\ x^{2} +2x-25 = x+5\\\\ x^{2} +x-30 = 0\\\\ x^{2} +6x -5x -30 = 0\\\\x(x+6) - 5(x+6) = 0\\\\(x-5)(x+6) = 0\\\\x = 5, -6[/tex]

If two fractions are between 0 and 1, can their product be more than 1? please explain. Thank You.

Answers

Answer:

B) always less than either of the original fractions

Step-by-step explanation:

We can easily Answer this by taking some values.

The question states that the two fractions, each have values between 0 and 1.

Let us say one of the fraction is 1/2 and the other fraction is 1/3 .

The product of the two fractions is 1/2 x 1/3 = 1/6 .

is lesser than both 1/2  and 1/3 .

So, the correct answer is that the product is always less than either of the original fractions.

The two fractions are between 0 and 1 their product will always less than either of the original fractions.

What is fraction?

A fraction is number expressed "as quotient, in which the numerator is divided by denominator".

According to the question,

If two fractions are between 0 and 1. In order to check their product be more than 1.

Let us assume one fraction is 1/2 and the other fraction is 1/3. The product of the two fractions:

1/2 x 1/3 = 1/6.

Since the value of fraction 1/2 is 0.5, the value of fraction 1/3 is 0.3333 and the value of fraction 1/6 is 0.166667.

It clearly shows 0.5 > 0.16667 and 0.3333 > 0.16667.

Hence, the two fractions are between 0 and 1 their product will always less than either of the original fractions.

A die is rolled. The set of equally likely outcomes is {1, 2, 3, 4, 5, 6}. Find the probability of getting a 9.

Answers

Answer:

you are only rolling 1 dice the probability of getting 9 is 0 there are only 6 sides to one die

Probability of getting a 9 is 0

Give that;

Total number of outcome in die = 6

Total numbers are {1, 2, 3, 4, 5, 6}

Find:

Probability of getting a 9

Computation:

Number of outcome 9 come in a die = 0

So,

[tex]Probability = \frac{Number\ of\ favourable\ outcomes}{Total\ outcomes}[/tex]

Probability of getting a 9 = 0 / 6

Probability of getting a 9 = 0

Lexus skateboards from his house to school 4 miles away. It takes him 20 minutes.
Assume that Lexus skateboards at a constant rate.
Part A
Write an equation to represent the number of miles, m, that Lexus can skateboard in t minutes.

Answers

Answer:

[tex]\displaystyle m = \frac{1}{5}\cdot t[/tex]

Step-by-step explanation:

Proportional Model

The number of miles m that Lexus can skateboard in t minutes can be modeled by:

m = kt

It's given that Lexus skateboard from his house to school for a distance of m=4 miles in t=20 minutes.

Substituting:

4 = k.20

Dividing by 20

[tex]k=\frac{4}{20}[/tex]

Simplifying:

[tex]k=\frac{1}{5}[/tex]

This produces the model

[tex]\displaystyle m = \frac{1}{5}\cdot t[/tex]

I used the equation y=4x+20.
