Add the opposite of the number 1 3/4 to the sum of the numbers 5 2/3 and (−2 5/6 )

Mathematics
1 answer:
MAVERICK [17]3 years ago
8 0

Answer:

Step-by-step explanation:

5 2/3 + (-2 5/6)

=\frac{17}{3}-\frac{17}{6}\\\\=\frac{17*2}{3*2}-\frac{17}{6}\\\\=\frac{34}{6}-\frac{17}{6}\\\\=\frac{34-17}{6}\\\\=\frac{17}{6}\\\\=2\frac{5}{6}

2 5/6 + (- 1 3/4) = 2 5/6 - 1 3/4

\frac{17}{6}-\frac{7}{4}\\\\=\frac{17*2}{6*2}-\frac{7*3}{4*3}\\\\=\frac{34}{12}-\frac{21}{12}\\\\=\frac{34-21}{12}\\\\=\frac{13}{12}\\\\=1\frac{1}{12}

How do you find the constant of variation when y=-(2/3) and x=3
Katyanochek1 [597]
You can't. If you think about the straight line on a graph, those numbers
describe a single point that the line goes through, and they don't tell you
anything about the slope of the line, or where it crosses the x-axis or the
y-axis.  So I don't think you can tell the constant of variation from one point.

AC = <br> Round your answer to the nearest hundredth.
dusya [7]

Answer:

AC ≈ 5.03

Step-by-step explanation:

We can solve the problem above using the trigonometric ratio, they are;

SOH CAH TOA

sin Ф = opposite / hypotenuse

cosФ= adjacent/ hypotenuse

tan Ф = opposite / adjacent

From the diagram above, in reference to angle B;

opposite =AC     and   adjacent =BC

Since we have opposite and adjacent, the best formula to use is

tanФ = opposite / adjacent

tan B = AC  / BC

tan 40 =  AC/ 6

Multiply both-side of the equation by 6

6× tan 40   =  AC/ 6  ×  6

At the right-hand side of the equation, 6 will cancel-out 6 leaving us with just AC

6×tan 40 = AC

5.034598  = AC

AC ≈ 5.03   to the nearest hundredths
