Answer:

a. 9/10

b. 3/4

c. 1/3

d. 1/15

e. 6/35

f. 1/15

g. 9/32

h. 4/15

Step-by-step explanation:

a. \frac{3}{10}+\frac{6}{10}=\frac{9}{10}

b. \frac{1}{3}+\frac{1}{4}+\frac{1}{6}=\frac{4}{12}+\frac{3}{12}+\frac{2}{12}=\frac{9}{12}=\frac{3}{4}

c. \frac{5}{6}-\frac{3}{6}=\frac{2}{6}=\frac{1}{3}

d. \frac{2}{3}-\frac{6}{10}=\frac{20}{30}-\frac{18}{30}=\frac{2}{30}=\frac{1}{15}

e. \frac{4}{10}*\frac{3}{7}=\frac{12}{70}=\frac{6}{35}

f. \frac{1}{6}*\frac{6}{15}=\frac{1}{15}

g. \frac{1}{8}/\frac{4}{9}=\frac{1}{8}*\frac{9}{4}=\frac{9}{32}

h. \frac{1}{5}/\frac{3}{4}=\frac{1}{5}*\frac{4}{3}=\frac{4}{15}

<u>Answer with step-by-step explanation:</u>

Reducing the given expressions to the lowest terms:

A. 3/10 + 6/10: \frac { 3 } { 10 } + \frac { 6 } { 10 } = \frac { 9 } { 10 }

B. 1/3 + 1/4 + 1/6: \frac { 4 + 3 + 2 } { 12 } = \frac { 9 } { 12 } = \frac { 3 } { 4 }

C. 5/6-3/6: \frac { 5 } { 6 } - \frac { 3 } { 6 } = \frac { 2 } { 6 } = \frac { 1 } { 3 }

D. 2/3-6/10: \frac{2}{3} -\frac{6}{10} = \frac{20-18}{30} =\frac{2}{30} =\frac{1}{15}

E. 4/10*3/7: \frac{4}{10} *\frac{3}{7} = \frac{12}{70}=\frac{6}{35}

F. 1/6*6/15: \frac{1}{6} *\frac{6}{15} = \frac{1}{15}

G. 1/8 divided by 4/9: \frac{\frac{1}{8} }{\frac{4}{9} } =\frac{1}{8} *\frac{9}{4} =\frac{9}{32}

H. 1/5 divided by 3/4: \frac{\frac{1}{5} }{\frac{3}{4} } =\frac{1}{5} *\frac{4}{3} =\frac{4}{15}

I NEED HELP PLEASE, THANKS! Use Cramer's Rule to find the solution of the system of linear equations, if a unique solution exist
iren2701 [21]

Answer:

Option B

Step-by-step explanation:

We are given the following system of equations -

\begin{bmatrix}-5x+2y-2z=26\\ 3x+5y+z=-22\\ -3x-5y-2z=21\end{bmatrix}

Now by Cramer's Rule, we would first write down the matrix of the coefficients , replacing each column with the answer column -

\begin{bmatrix}-5&2&-2\\ 3&5&1\\ -3&-5&-2\end{bmatrix} ,

\begin{bmatrix}26\\ -22\\ 21\end{bmatrix}

Replace each column of the coefficients shown at the top, with the answer column at the bottom respectively -

\begin{bmatrix}-5&2&26\\ 3&5&-22\\ -3&-5&21\end{bmatrix}

Now solve through Cramer's Rule -

x = Dx / D = - 6,

y = Dy / D = - 1,

z = Dz / D = 1

<u><em>Solution = ( - 6, - 1, 1 ) = Option B</em></u>

If 1/2 hour Naomi stretches her neck; every 1/3 hour she stretches her legs; and every 1/6 hour she stretches her ams. Which par
allsm [11]
Neck: In 2/3 of an hour Naomi will stretch her neck one (there's not enough time for two neck stretches, that would require an hour).
Legs: In 2/3 of an hour, she will stretch her legs twice (1 stretch every 1/3 of an hour for 2/3 of an hour equals 2).
Arms: In 2/3 of an hour she will stretch her arm four times (2/3 divided by 1/6 equals 4). 

Total stretches: 1 neck stretch, 2 legs stretches, and 4 arms stretches.

In triangle ABC, the measure of C is 90°,<br> AC=24, and BC=10. What is the value of sin<br> A?
Sergio039 [100]

Answer:

Sin A = 0.38462

Step-by-step explanation:

From the trigonometric function,

Sin A = \frac{Opposite}{Hypotenuse}  ................... 1

So that, applying the Pythagoras theorem to determine the value of hypotenuse,

/Hyp/^{2} = /Opp/^{2} + /Adj/^{2}

            = 24^{2} + 10^{2}

            = 576 + 100

/Hyp/^{2} = 676

Hyp = \sqrt{676}

       = 26

The hypotenuse of the triangle is 26.

Thus, from equation 1;

Sin A = \frac{10}{26}

Sin A = 0.38462
