spayn [35]3 years ago

4 0

Using the distance formula
d= square root of (x2-x1)^2+(y2-y1)^2

(9-9)^2+(10-3)^2
0^2+7^2
0+49
Square root of 49 is 7
d=7

Which conversion factors are used to convert 12 m/s to kilometers per minute?

Lera25 [3.4K]

Answer:

see the procedure

Step-by-step explanation:

we have

$12\ \frac{m}{s}$

Remember that

$1\ km=1,000\ m$

To convert m to km multiply by (1/1,000)

$1\ min=60\ sec$

To convert sec to min multiply by (1/60)

substitute

$12\ (\frac{(1/1,000)}{(1/60)})=12(\frac{60}{1,000})=0.72\ \frac{km}{min}$

The measurement of the angles of RSC are given by the expression in the table

Fudgin [204]

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in the triangle = 180°

Sum the 3 angles and equate to 180

31 + x + 4 + 3x + 9 = 180, that is

4x + 44 = 180 ( subtract 44 from both sides )

4x = 136 ( divide both sides by 4 )

x = 34

Thus

∠ S = x + 4 = 34 + 4 = 38°

∠ T = 3x + 9 = 3(34) + 9 = 102 + 9 = 111°
