Amanda [17]3 years ago

6 0

Step-by-step explanation:

As,

x + 14 + 3x = 90 [Complementary Angles]

=> 4x = 90 - 14

=> 4x = 76

$= > x = \frac{76}{4}$

=> x = 19

Hence,

<1 = x + 14°

 = 19 + 14 = 33°

<2 = 3x

 = 3 × 19° = 57°

A road bike has a wheel diameter of 622 mm. What is the circumference of the wheel? Use 3.14 for pi

Ghella [55]

Answer:

Circumference ≅ 195 mm

Step-by-step explanation:

The circumference of a circle is equal to: $2*\pi *radius$

Since $Diameter = 2*radius$ we can replace that in the circumference equation giving us:

$Circumference = \pi *Diameter$

We know Diameter = 622 mm and pi = 3.14 so:

$Circumference = \pi *Diameter = 3.14 * 622 mm = 195.308 mm$

The Cinemania theater showed 108108108 different movies last year. Of those, 151515 movies were action movies. Based on this dat

Ahat [919]

Answer:

Option B.

Step-by-step explanation:

It is given that,

Last year the total number of movies = 108

Number of action movies = 15

Based on this data, we need to find a reasonable estimate of the probability that the next movie is an action movie.

So, the required probability is:

$\text{Probability}=\dfrac{\text{Number of action movies}}{\text{Total number of movies}}$

$\text{Probability}=\dfrac{15}{108}$

Hence, the correct option is B.

Factor completely 15x^5 + 12x^4-24x^3-3x^2

diamong [38]

Answer:

3x^2 (5x^3 + 4x^2 - 8x - 1)

Step-by-step explanation:

The given expression is 15x^5 + 12x^4-24x^3-3x^2

Here we have to find the GCF of all the above terms.

The GCF is 3x^2, let's take out 3x^2 and write the remaining terms in the parenthesis.

15x^5 + 12x^4-24x^3-3x^2

=3x^2 (5x^3 + 4x^2 - 8x - 1)

Therefore, the factors are 3x^2 and (5x^3 + 4x^2 -8x -1).

15x^5 + 12x^4-24x^3-3x^2 = 3x^2 (5x^3 + 4x^2 -8x -1)

Thank you.
