Answer:

Step-by-step explanation:

74 +  97 = 171 mm

Length of the train track = 171 mm = 171÷ 1000 = 0.171 m

Answer:

0.171 m

Step-by-step explanation:

First, let's determine how many mm of track he has in total...

74mm+97mm=171 mm

Now, we can set up a unit converter to convert mm to m (note that 1 mm is 10^{-3{ m)...

171mm(\frac{10^{-3}m}{1mm})

The "mm" cancels out...

171*10^{-3}m=0.171m

Miranda made 6.88 pounds of trail mix. She used 4.96 pounds of granola for the mix. Miranda wrote the equation w + 4.96 = 6.88 t
joja [24]

Step 1: to solve this equation first subtract 4.9 from both sides.

w + 4.9 - 4.9 = 6.88 - 4.9

When you reduce that your answer should be w = 1.92

Therefore the weight of ingredients other than granola in Miranda's trail mix is 1.92

Answer:

Step-by-step explanation:

oh law of sines   soo  sin(A) / a = Sin(B) / b

2a)

here DE = side f   then let's find that side with law of sines and plug side f in as 'a' in law of sines , so

Sin(28) / a = Sin(54) / 31  ( where a = f = DE )

can you do the algebra here Emily?  or do you want me to show that?

Sin(28) *31 / Sin(54) = a

17.989 =a

18.0 =a       (rounded to nearest 10th)

DE = 18.0 m

2b)

find RT  where RT = side a

since they give use 2 of the other sides of the triangle we can quickly figure out the S angle.   180 = 71+62+S   so  S = 47°  ( I'm going kinda fast b/c I don't know how much time you have  :? )

then Sin(A) /a = Sin(B) / b

Sin(47) / a = Sin(62) / 29

Sin(47) *29 / Sin(62) = a

24.020 = a

RT = 24.0 meters  ( rounded to nearest 10th )

2c)

they want us to find ∠X with law of sines soo

I'll just use the letter they give us for variables

Sin(X) / x  = Sin(Y ) / y

Sin(X) = x* Sin(y) / y

X = arcSin [ 14 * Sin(108) / 34 ]

X = arcSin [ 0.3916115]

X = 23.0548°

X= 23°  ( rounded to nearest degree )

2d)

they ask us to find ∠E

I'll , again, use the letter they give us for variables

Sin(E) / e = Sin( F ) / f

Sin(E) / 18 = Sin(78) / 30

E = arcSin[ 18 * Sin(78) / 30 ]

E = arcSin [ 0.5868856 ]

E = 35.936 °

E = 36 °    ( rounded to nearest degree )
