Probability

You will add both probabilities after finding them both.

The spinner is 1/2 because a and b are half of the full spinner.

The cube is 1/6 because 2 is only one unit of the cube.

1/2+1/6=2/3

Meaning, the probability of both these events happening is 66.6% approximately.

Does the triangle with the side lengths of 6ft, 7ft, and 8 ft form a right triangle

Zigmanuir [339]

Answer:

No.

Step-by-step explanation:

When the side lengths are consecutive integers, only the lengths 3, 4, and 5 will form a right triangle.

8^2 ≠ 6^2 + 7^2 . . . . for a right triangle, the square of the hypotenuse must be the sum of the squares of the legs

64 ≠ 36 + 49 = 85

A and b are monomials where a = 125 and b = 27p12. what is the factored form of a – b?

torisob [31]

The factored form of a - b is $\left(5-3 p^{4}\right)\left(25+15 p^{4}+9 p^{8}\right)$ .

<h3>What is monomial factorization ?</h3>

A monomial is an expression that is the product of constant and non-negative integer powers of x, like $3x^{2}$ ..

A monomial is expressed as a product of two or more other monomials when it is factored.

Here,

a = 125

$b=27 p^{12}$

To find: a - b

a - b = 125 - $27 p^{12}$$

a - b = $5^{3}-\left(3 p^{4}\right)^{3}$$

We know that,

$x^{3}-y^{3}=(x-y)\left(x^{2}+x y+y^{2}\right)$

Finding the factored form of a - b using this method:

$a - b=\left(5-3 p^{4}\right)\left(5^{2}+5\left(3 p^{4}\right)+\left(3 p^{4}\right)^{2}\right)$

$a-b=\left(5-3 p^{4}\right)\left(25+15 p^{4}+9 p^{8}\right)$

So, factored form of a - b is $\left(5-3 p^{4}\right)\left(25+15 p^{4}+9 p^{8}\right)$ .

A gallon of gasoline costs $2.96. Your car has a 25-gallon gas tank and can travel 28.8 miles on each gallon of gasoline. You ta

Andreas93 [3]

Answer:

$70.56

Step-by-step explanation:

Lets convert the mixed number (trip length) to decimal.

We know 3/5 (by long division) is 0.6, so 705 3/5th = 705.60 miles

Now, let's come to the problem:

1 gallon = 28.8 miles (mileage)

$2.96 = 28.8 miles

To find cost per mile, we divide:

$\frac{2.96}{28.8}=0.10$

That means, it costs $0.10 per mile

Since we want to travel 705.60 miles, we multiply to find the cost:

$0.10 per mile * 705.60 miles = $70.56
