Use the law of sines to find the length of side c

Answers

Answer 1

Answer:

Look at the picture.

The law os sine:

$(a)/(\sin A)=(b)/(\sin B)=(c)/(\sin C)$

We have

$m\angle A=46.7^o\n\nm\angle C=48^o\n\na=44\n\nc=?$

Substitute:

$(c)/(\sin48^o)=(44)/(\sin46.7^o)\n\n\boxed{c=44.93}\to\boxed{A.}$

Because the math is the same on all of these problems, I will only give a complete explanation for the first problem.

2. To line these numbers up from greatest to smallest, we must first convert all of the values to decimals. We can do this by completing the fractions, or just dividing the numerator by the denominator.

1 $(1)/(4)$ = $(5)/(4)$ = 1.25

1 $(1)/(10)$ = $(11)/(10)$ = 1.1

Now, we have our four decimals: 1.16, 1.25, 1.37, and 1.1

When we organize them by order of greatest to least, it looks like this:

1.37, 1.25, 1.16, 1.1

And when the fractions are put back in their rightful spots, it will be

1.37, 1 $(1)/(4)$ , 1.16, 1 $(1)/(10)$

3. For this one, we have the numbers $(5)/(8)$ , 0.5, $(2)/(5)$ , and 0.78.

Let's convert our fractions:

$(5)/(8)$ = 0.625

$(2)/(5)$ = 0.4

Now, we can organize:

0.78, 0.625, 0.5, and 0.4.

Putting our fractions back in, we end up with this:

0.78, $(5)/(8)$ , 0.5, and $(2)/(5)$ .

4. Here, we're organizing from smallest to largest, so we need to be aware of this when solving.

Convert the fractions:

$(1)/(2)$ = 0.5

$(2)/(3)$ = 0.6...

Now, we can organize from smallest to greatest:

0.39, 0.5, 0.6, 0.66...

Putting our fractions back in...

0.39, $(1)/(2)$ , 0.6, $(2)/(3)$ .

5. Let's convert our fractions:

7 $(1)/(4)$ = $(29)/(4)$ = 7.25

7 $(3)/(4)$ = $(31)/(4)$ = 7.75

Now, we can organize from smallest to greatest:

7.25, 7.4, 7.75, 7.77

Putting our fractions back in, it looks like this:

7 $(1)/(4)$ , 7.4, 7 $(3)/(4)$ , 7.77.

6. For these next two, we're back to greatest to smallest. Just to keep in mind.

To convert our fractions...

$(3)/(10)$ = 0.3

$(3)/(5)$ = 0.6

To organize:

0.222, 0.3, 0.53, 0.6

With our fractions,

0.222, $(3)/(10)$ , 0.53, $(3)/(5)$ .

7. Back to our fractions.

3 $(1)/(5)$ = $(16)/(5)$ = 3.2

3 $(1)/(4)$ = $(13)/(4)$ = 3.25

To organize:

2.96, 3.2, 3.25, 3.48

Putting our fractions back,

2.96, 3 $(1)/(5)$ , 3 $(1)/(4)$ , 3.48.

8. Just looking at these, we can remember that the fraction $(1)/(5)$ translates to the decimal 0.2, and we have one judge giving an 8.2, and one judge giving an 8 $(1)/(5)$ . These scores are identical so these two judges had the closest result.

And there you have it for your answers.
Hope that helped! =)

The perimeter of an isosceles triangle is 15.6m. Find the lengths of its sides, if:The base is 3m smaller than a leg.

Answers

Answer:

so length of sides is 6 .2 m ( other side will also be 6.2 m)

base = 3.2 cm

Step-by-step explanation:

solution

let the length of sides of isosceles triangle is = x

as two sides of of isosceles triangle are equal

let the length of the side be x

so length of side = x

base = x -3 ( as it is 3 m smaller in length )

according to formula of perimeter of isosceles triangle

perimeter = 2 (side) + Base

adding the values

15.6 = 2 (x) + x-3

15.6 = 2x +x -3

15.6 = 3x-3

15.6 = 3( x-1) taking 3 common

dividing both sides by 3

15.6/3 = 3(x-1)/3

5.2 =x-1

or x -1 = 5.2

adding 1 from both sides

x-1 +1 = 5.2 +1

x = 6.2

so length of sides is 6 .2 m ( other side will also be 6.2 m)

base = x-3 = 6.2-3 = 3.2 m

6 .2 m ,6.3 m, 3.2 m

Hi there! :) I believe the answer is B: 1/8. The reason I picked 1/8 is because you add all the numbers together, so since we have 5,9, and 2 ; 5+2+9=16.
So since it says what is the probability that the marble will red. There are 2 red marbles so it would 2/16 but there is NO 2/16 so we simplify. 2/2=1 and 16/2= 8 So your answer is 1/8! Hope I helped :) :D Have a amazing day! ;)

Hai, Brainiac!

Great question!

Basically to find the answer, first you add the number of each marble there is.

5 black marbles + 9 white marbles + 2 red marbles = 16 marbles altogether.

Red marbles to the total number of marbles altogether is 2:16, a ratio.

Simplified, that would be 1:8 marbles, or, answer choice B, so your answer would be 1/8 :D

Hope this helps!

Which weighs more: a pound of feathers or a pound of rocks?(And this was too businesses! What if I want to know how much to price stuff?)

Answers

They both weigh the same. They are both a pound each. One rock may weigh a pound where a thousand feathers may weigh a pound, but they still are both the amount needed to be a pound each.

A pound is a pound it doesn't matter what it is.
