Detecting...

Your answer would be:

$0.025 = 1/40 

0.025/1 * 1000/1000 = 25/1000

25 \div 25 / 1000 \div 25 = 1/40

1/40 is your answer.$

Help trigonometry<br> cccccc

Answer:

Step-by-step explanation:

<h3>Trigonometry ratios: </h3>

$\sf Sin \ \theta =\dfrac{opposite \ side }{hypotenuse} =\dfrac{12}{37}$

To find the adjacent side use Pythagorean theorem.

Opposite side² + adjacent side² = hypotenuse²

adjacent side² = hypotenuse² - opposite side²

= 37² - 12²

= 1369 - 144

= 1225

adjacent side = √1225

= 35

$\sf tan \ \theta =\dfrac{Opposite \ side }{adjacent \ side}\\\\tan \ \theta = \dfrac{12}{35}$

Answer:

Step-by-step explanation:

y - 3 = 1/4(x - 4)

now use algebra to get the above point-slope formula in the slope-intercept formula

y - 3 = 1/4(x - 4)

y - 3 = 1/4x -1

y = 1/4x +2

now that you have the slope-intercept form graph it

Solve for x. 2(x + 14) + x = 70a. 11b. 12c. 14d. 17

Mariulka [41]

Hello!

To solve for the variable x, we need to follow the rules of SADMEP. SADMEP is ONLY used when solving algebraic equations. SADMEP is an acronym for subtraction, addition, division, multiplication, exponents, and parentheses. Also, when solving for x, our main goal is to isolate x to one side of the equation.

2(x + 14) + x = 70 (use the distributive property)

2x + 28 + x = 70 (simplify - add)

3x + 28 = 70 (subtract 28 from both sides)

3x = 42 (divide both sides by 3)

x = 14

When solving ANY algebraic equation, we need check our answer. To check your answer, you substitute the x-value, which is 14 in this case, into the original equation and solve using PEMDAS.

2(x + 14) + x = 70 (substitute x = 14)

2(14 + 14) + 14 = 70 (simplify the terms inside the parentheses)

2(28) + 14 = 70 (simplify - multiply)

56 + 14 = 70 (simplify - add alike term)

70 = 70 | This is correct!

Therefore, your final answer is x = 14, which is choice C.

Someone PLEASE HELP ME<br><br>Find the slope of the line <br><br>Algebra 1

olasank [31]

Answer:

Step-by-step explanation:

using rise over run method, from (0,20) to (1,80) the line slants up by degree of 60 per one unit so the slope is 60.
