Given m ||n, find the value of x.
+
(x+18)
(5x-6)°

Answers

Answer:

x = 28

Step-by-step explanation:

(x + 18)° + (5x - 6)° = 180° (supplementary angles)

Solve for x

x + 18 + 5x - 6 = 180

Add like terms

6x + 12 = 180

6x = 180 - 12 (subtraction property of equality)

6x = 168

x = 168/6 (division property of equality)

x = 28

Answer:

The area would be 153.86

Step-by-step explanation:

Since the diameter is 14, the radius would be 7.

The area is pi times the radius squared.

7 squared is 49.

If your using 3.14 for pi, then its 3.14 times 49.

That gives you 153.86.

Write an equation for the nth term of the arithmetic sequence. Then find a 30

-9, -6, - 3,0, ...

Answers

Answer:

The nth term is given by: [tex]a_n = -9 + 3(n-1)[/tex]

The 30th term is 78.

Step-by-step explanation:

Arithmetic sequence:

The nth term of an arithmetic sequence is given by:

[tex]a_n = a_1 + (n-1)d[/tex]

In which [tex]a_1[/tex] is the first term and d is the common difference between terms.

-9, -6, - 3,0

This means that [tex]a_1 = -9, r = -6 - (-9) = -6 + 9 = 3[/tex]. So

[tex]a_n = -9 + 3(n-1)[/tex]

30th term:

[tex]a_30 = -9 + 3(30-1) = -9 + 87 = 78[/tex]

The 30th term is 78.

Answer:

R = 0.8815 ;

y = 6.14679X + 2.33028 ;

14.624

Step-by-step explanation:

Using an online correlation Coefficient calculator, the correlation Coefficient, R between the number of lawn fertilizer sold and the number of lawn mowers sold is 0.8815. This R value depicts a strong positive correlation between both variables.

The regression line equation obtained by Plotting the values to generate a linear model is :

y = 6.147X + 2.330

With ;

Slope or gradient being 6.147

Intercept = 2.330

C.)

x = 2

y = 6.147X + 2.330

y = 6.147(2) + 2.330

y = 14.624

Step-by-step explanation:

The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, for example, that 2(3 + 4) = 2×3 + 2×4.

Support your answer with evidence from the text that is either directly stated or implied.The Text: By the time I was twelve, I was selling over $1,000 in bow ties annually. Thats when I got an email from the producers of Shark Tank, a show that gives entrepreneurs the chance to present their companies in front of a panel of investors. At first, my mom turned down the offershe didnt know what the show was. But when we started doing research and kept in contact with the producers, she agreed to let me fly to California to film. I decided to ask the investors for $50,000 for a fifteen-percent stake in my company. For months, I recited lines, practicing in front of a camera, my parents and occasionally my teddy bears. Despite my preparation, when the day finally came, I was terrified. Walking down the blue-lit hallway, I gripped my moms hand so tightly that five years later, she still jokes that I cut off her circulation. When the producers cued me to begin, my brain went empty and the words I had practiced fell away. After a deep breath, I somehow gathered myself and recited my pitch. But none of the sharks wanted to take the deal Id offered. They told us we didnt need their help, that we were growing at the right speed and should keep the companys ownership for ourselves. One investor, Kevin, offered to contribute to my business if I gave him three dollars for every tie I sold for the life of the company, but all of the other sharks told me not to take the deal. I declined, leaving the stage with no deal, but with the promise of a mentorship from another investor, Daymond John. As I walked backstage, my eyes filled with tears and I started sobbing. My goal for months had been to leave with a deal, and I had failed. The moment when I messed up my pitch replayed in my head. But as time passed, I realized that the sharks had actually given me a gift.
