the sides of a triangle are 3 whole 1 by 6 cm 4 whole 2 by 3 cm and 5 whole 2 by 3 cm. Find the total length of the three sides

Lyrx [107]

Answer:

$16\frac{2}{3}$ cm

Step-by-step explanation:

Given dimensions:

$3\frac{1}{6}$ cm by $4\frac{2}{3}$ cm by $5\frac{2}{3}$ cm

The total length:

it is the sum of all the sides;

$\frac{19}{6} + \frac{14}{3} + \frac{17}{3}$

LCM of the denominators = 6 ;

$\frac{38 + 28 + 34}{6}$ = $\frac{100}{6}$

= $\frac{50}{3}$

= $16\frac{2}{3}$ cm

Lisa and her husband are each starting a saving plan. Lisa will initially set aside

Lelechka [254]

Please work on your formatting.

If this lady starts out with $125 and then saves an additional $50.85 per week after that, the formula for (her) savings is

S(x) = $125 + ($50.85 / week) x, where x is the # of weeks.

Shelly and her family are riding the Pikes Peak Cog Railway. The table shows the approximate distances the train has covered at

irga5000 [103]

Relationship between distance and time is A. d = 0.12m

Step-by-step explanation:

For an object moving in uniform motion (=constant velocity), the relationship between distance covered and time taken is given by

$d=vt$

where

d is the distance

v is the velocity

t is the time

Therefore, in order to find the relationship between distance and time, we have to find the velocity of the train.

This can be done by using the data of the table: in fact, the velocity is the ratio between the distance covered and the time taken to cover that distance.

Therefore, if we take for instance the last point of the table:

d = 2.4 miles (distance covered)

t = 20 minutes (time taken)

So the velocity is

$v=\frac{d}{t}=\frac{2.4}{20}=0.12 mi/min$

And therefore, the relationship between distance and time is

$d=0.12 m$

(where m is the time in minutes)

Choose the point-slope form of the equation below that represents the line that passes through the point (6, −3) and has a slope

olasank [31]

I hope this helps you

x'=6 y'= -3 slope = 1/2

slope. (x'-x)=y'-y

1/2 (6-x)=-3-y

1/2.6-x/2=-3-y

3-x/2= -3-y

y=x/2-6

Answer:

Step-by-step explanation:

You are looking for sin, which is the opposite side over the hypotenuse. You can use "Some other hippy caught another hippy tripping on acid" to remember Sin=opposite/hypotenuse; Cos= adjacent/ hypotenuse; Tan= opposite/adjacent.
