Answer:

(-\frac{7}{6} )

Step-by-step explanation:

From the question the emerald was located at a depth which is between -1/2 and -1 2/3 meters

This statement can be written as

(-1\frac{2}{3}) -(-\frac{1}{2} )

To get the depth, you find the depth of the emerald location, you find difference between the two mentioned depths

-(1\frac{2}{3} )-(-\frac{1}{2} )\\\\

Change first term to improper fraction

=-(\frac{5}{3} )-(-\frac{1}{2} )\\\\

Find the LCM to solve the operation the involves the fractions.The Least common multiple here is 6 i.e 3*2

=(-\frac{5}{3} )-(-\frac{1}{2})\\

=\frac{-5}{3} +\frac{1}{2} =\frac{-10+3}{6} =\frac{-7}{6}

The number that could represent the depth at which the emerald was located is

=\frac{-7}{6}

If the fourth multiple of 3 is subtracted from the third multiple of 4 what is the difference
anyanavicka [17]
The difference is zero if you aren't insinuating that the term, "multiple" doesn't involve exponential factors.

3•4 = 12
4•3 = 12

12
-12
___
0


However, if you are saying one multiple of 3 involves exponential powers, Then 3^4 is 81 and 4^3 is 64

4^3 = 64

64 - 81 = -17

In ΔRST, s = 58 inches, ∠R=115° and ∠S=19°. Find the length of r, to the nearest 10th of an inch.
Lorico [155]

Answer:

365.9 Inches

Step-by-step explanation:

To find the value of Sin A can be found using the sine rule. the rule states that the ratio of the length facing an angle in a triangle to the sine of the angle is constant. As such,

a/Sin A = b/Sin B = c/Sin C

Where is a is the side facing angle A, b is the side facing angle B and c is the side facing angle C.

Hence,

58/Sin 19 = r/Sin 115

r = 58 Sin 115/ Sin 19

= 365.9 Inches

I need to finish this usa test prep now plz help
Slav-nsk [51]

Answer:

R = 101

S = 131

Step-by-step explanation:

First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.

T=180-128

T=52

You also know that all angles in a triangle equal to 180

Use that to find angle S

180 = R+S+T

180 = 79 + S + 52

180 - 79 - 52 = S

49 = S, exterior S = 180-49 = 131

Exterior R = 180 - 79 = 101

Now add all your exteriors

True.

Isometry is such transformation where the shape of observed body is not manipulated on itself but rather the position of it is manipulated.

Hope this helps.
