What is the decimal equivalent of 1/3?

A. 3.1

B. 1.3
_
C. 0.3

D. 0.3

Answers

Answer: C.  0.3

Step-by-step explanation:

To convert 1/3 so you can write it as a decimal, simply divide the numerator by the denominator, like this:

= 1/3

= 1 ÷ 3

≈ 0.3333333

Therefore, the solution to 1/3 as a decimal is as follows:

1/3 ≈ 0.3333333

Answer:

0.3

Step-by-step explanation:

Use “Bus stop” long division.

1/3 is the same as saying 1÷3, or “how many times does 3 go into 1”

3|1.000

How many times does 3 go into 1? Zero remainder one. We take the one over into the next column. So now we have:

3|0.1000

0

So, how many 3s go into 10? Three with one remaining. We take the one into the next column again.

3|0.0100

0.3

How many 3s go into 10? 3 again, remainder 1.

3|0.0010

0.33

This process continues until you end up with no remainder - but that doesn't ever happen in the decimal expansion of 1/3,

1/3=0.333… with recurring (infinitely repeating) 3s, and that's why we tend to prefer factions where we can use them.

1/3=0.3

2. Given A=15°, b=8, and a=6, use the Law of Sines to solve the triangle (if possible)
for the value of c. If two solutions exist, find both. Round answer to two decimal places.
A) c=11.01
B) c=2.10 and 13.36
C) c=12.14
D= c=1.12 and 10.24
E) not possible

Answers

Answer:

B

Step-by-step explanation:

The Law of Sines states that

sinA/a = sinB/b = sinC/c

We know A, a, and b. Given this, we can solve for B, and given that, we can solve for C and then c.

First, we solve for B.

sinA/a = sinB/b

sin(15°)/6 = sinB/8

sin(15°)/6 * 8 = sinB

arcsin(sin(15°)/6 * 8) = B ≈ 20.187

Note that there can be a second B value. We can check if there is a second B value by first subtracting the B value we got from 180.

180 - 20.187 = 159.813

Next, we can add that to our existing angle, A = 15°. If that is less than 180, then we do have a second solution. 159.813 + 15 = 174.813 < 180 so there does exist a second solution where B = 159.813

Next, we can solve for C.

We know that the angles in a triangle add to 180°, so A + B + C = 180. Therefore, for the first solution:

15 + 20.187 + C = 180

C = 180 - 15 - 20.187 = 144.813°

and for the second:

15 + 159.813 + C = 180

C = 180 - 15 - 159.813 = 5.187

Finally,

sinA/a = sinC/c

multiply both sides by c to no longer have it as a denominator

sinA * c / a = sinC

divide both sides by (sinA/a) to isolate c

for the first solution:

c = sinC*a/sinA = 13.35868 ≈ 13.36

and for the second:

c = sinC*a/sinA ≈ 2.10

Identify the percent in 12 is 50% of 24

Answers

Answer:

50 percent of 24 is 12. 3.

Step-by-step explanation:

50 percent *24

= (50/100)*24

= (50*24)/100

= 1200/100 = 12

Now we have: 50 percent of 24 = 12

Question: What is 50 percent of 24?

We need to determine 50% of 24 now and the procedure explaining it as such

Step 1: In the given case Output Value is 24.

Step 2: Let us consider the unknown value as x.

Step 3: Consider the output value of 24 = 100%.

Step 4: In the Same way, x = 50%.

Step 5: On dividing the pair of simple equations we got the equation as under

24 = 100% (1).

x = 50% (2).

(24%)/(x%) = 100/50

Step 6: Reciprocal of both the sides results in the following equation

x%/24% = 50/100

Step 7: Simplifying the above obtained equation further will tell what is 50% of 24

x = 12%

Therefore, 50% of 24 is 12

Answer:

803.84 millimeters²

Step-by-step explanation:

How do we find the area of a circle?

The area of a circle is πr², where r = radius. In this case, we have to approximate pi to 3.14.

Solving

[tex]3.14 *16^2[/tex] [tex]3.14*256[/tex] [tex]803.84[/tex]

Therefore, the area is 803.84 square millimeters.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Solution:

We know that:

Radius = r = 16 mmArea of circle = (π)(r²)

Finding the area of the circle:

Area of circle = (3.14)(16²)=> Area of circle = 3.14 x 16²=> Area of circle = 3.14 x 256=> Area of circle = 803.84 mm²
