What is 0.16666666667 rounded to?

1 answer:

5 0

It would be 0.17 because 7 is higher than 6 and you would add 1 to the 6.

remember this saying...
5 or more add 1 more 4 or less just ignore

Answer:

Step-by-step explanation:

First question:

You are given a side, a, and its opposite angle, A. You are also given side b. Use that in the law of sines and solve for the other angle, B.

$\dfrac{a}{\sin A} = \dfrac{b}{\sin B}$

$\dfrac{10}{\sin 30^\circ} = \dfrac{40}{\sin B}$

$\dfrac{1}{0.5} = \dfrac{4}{\sin B}$

$\sin B = 2$

The sine function can never equal 2, so there is no triangle in this case.

Answer: no triangle

Second question:

You are given a side, b, and its opposite angle, B. You are also given side c. Use that in the law of sines and solve for the other angle, C.

$\dfrac{b}{\sin B} = \dfrac{c}{\sin C}$

$\dfrac{10}{\sin 63^\circ} = \dfrac{}{\sin C}$

$\sin C = \dfrac{8.9\sin 63^\circ}{10}$

$C = \sin^{-1} \dfrac{8.9\sin 63^\circ}{10}$

$C \approx 52.5^\circ$

One triangle exists for sure. Now we see if there is a second one.

Now we look at the supplement of angle C.

m<C = 52.5°

supplement of angle C: m<C' = 180° - 52.5° = 127.5°

We add the measures of angles B and the supplement of angle C:

m<B + m<C' = 63° + 127.5° = 190.5°

Since the sum of the measures of these two angles is already more than 180°, the supplement of angle C cannot be an angle of the triangle.

Answer: one triangle

Jennifer made 5 liter of punch for her for her party her brother made another 750ml if they combine the two batches how many 180

kykrilka [37]

5 liters = 5000ml

If they combine, they would have
5000 + 750 = 5750ml

one serving = 180ml
Number of serving = 5750 ÷ 180 = 31 serving with 170ml remaining

a. a=40° (alternate interior angles)

b+40°=180°( supplementary angles)

b=140°

c= d= 140°( vertically opposite angles)

d=b=140°( corresponding angles)

b. 2a+120°=180° (supplementary angles)

2a=60°

a=30°

c. a+110°=180°( supplementary angles)

a=70°

b+70°=180°( supplementary angles)

b=110°

c+110°=180°( supplementary angles)

c=70°

c=d=70( corresponding angles)

Four times the first of three consecutive even integers is six more than the product of two and the third integer. Find the inte

sesenic [268]

First integer = x

Second integer = x + 2

Third integer = x + 4

Since four times the first integer equals six more than the product of two and the third integer.

4x = 6 + 2(x + 4)

4x = 6 + 2x + 8

2x = 14

x = 7.

Hence,

First integer = x = 7

Second integer = x + 2 = 7 + 2 = 9

Third integer = x + 4 = 7 + 4 = 11.

hope this helps
