oee [108]

Answer:

$4.5

Step-by-step explanation:

First, multiply 1.50 by 4 (since that how many friends there are)

1.5 * 4 = 6

Second, subract 24 by 6

24 - 6 = 18

Finally, divide 18 by 4

18 / 4 = 4.5

And there, the answer is $4.5. Hoped this helped :))

Use trig ratios to find the measure of the angle in this triangle. A .cos^-1(4/5) B. tan(4/5) tan^-1(4/5) C. sin(4/5) D. cos(4/5
ololo11 [35]

Answer:

The answer is A

Step-by-step explanation:

Step 1: Use Cosine to find ∅

Cos∅=\frac{4}{5}

∅=Cos^{-1}(\frac{4}{5})

Therefore the answer is A

Please help solve this. Will give brainiest. Please explain your answers, as I have no idea how to solve this, but I tried my be
tatyana61 [14]

Answer:

Step-by-step explanation:

-2(6+s) ≥ -15 -2s

step 1: first remove the parenthesis

             -12 - 2s ≥ -15 -2s

step 2: add +12 to each side to combine like and unlike terms

           -12 - 2s + 12 ≥ 15 - 2s +12

           = -2s ≥ 27 - 2s

step 3: then add +2s to each side to obtain unknown sides

-2s + 2s ≥ 27 -2s + 2s

0 ≥ 27 + 0

Answer: No solution

In Summary

Step 1 Eliminate fractions by multiplying all terms by the least common denominator of all fractions.

Step 2 Simplify by combining like terms on each side of the inequality.

Step 3 Add or subtract quantities to obtain the unknown on one side and the numbers on the other.

Step 4 Divide each term of the inequality by the coefficient of the unknown. If the coefficient is positive, the inequality will remain the same. If the coefficient is negative, the inequality will be reversed.

Step 5 Check your answer.

Cos(theta) = - 3/4 and is in the 3rd quadrant, find the following:
elena-14-01-66 [18.8K]

Answer:

\begin{gathered} sin(\theta)=\frac{-\sqrt{7}}{4} \\ cos(\theta)=-\frac{3}{4} \\ tan(\theta)=\frac{\sqrt{7}}{3} \\ csc(\theta)=-\frac{4}{\sqrt{7}} \\ sec(\theta)=-\frac{4}{3} \\ cot(\theta)=\frac{3}{\sqrt{7}} \end{gathered}

Step-by-step explanation:

If theta is in the third quadrant, draw the diagram to easily identify the other trigonometric relations:

Solve for the missing leg of the triangle, using the Pythagorean theorem:

\begin{gathered} \text{ adjacent}^2+\text{ opposite}^2=\text{ hypotenuse}^2 \\ -3^2+\text{ opposite}^2=4^2 \\ \text{ opposite=}\sqrt{16-9} \\ \text{ opposite=}\sqrt{7} \end{gathered}

Therefore, for the trigonometric relationships:

\begin{gathered} \text{ sin\lparen}\theta)=\frac{opposite}{hypotenuse} \\ \text{ cos\lparen}\theta)=\frac{adjacent}{hypotenuse} \\ tan(\theta)=\frac{opposite}{adjacent} \\ csc(\theta)=\frac{hypotenuse}{opposite} \\ sec(\theta)=\frac{hypotenuse}{adjacent} \\ cot(\theta)=\frac{adjacent}{opposite} \end{gathered}

Now, substitute and solve for the relations:

\begin{gathered} sin(\theta)=\frac{-\sqrt{7}}{4} \\ cos(\theta)=-\frac{3}{4} \\ tan(\theta)=\frac{\sqrt{7}}{3} \\ csc(\theta)=-\frac{4}{\sqrt{7}} \\ sec(\theta)=-\frac{4}{3} \\ cot(\theta)=\frac{3}{\sqrt{7}} \end{gathered}

How is 27.97 and 27.93 greater than 27.99
lys-0071 [83]
It isn't.

27.97
27.93
27.99
^^.^ ^

2, 2, and 2 are equal
7, 7, and 7 are equal
9, 9, and 9 are equal

9 > 7
7 > 3

27.99 is the largest
