WHAT IS 3/8 DIVIDED BY 1/2

Answers

Answer 1
Answer:

Answer: 3/4

Step-by-step explanation: Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the divison sign to multiplication and flip the second fraction.

So here, 3/8 divided by 1/2 can be rewritten as 3/8 × 2/1.

Now we are simply multiplying fractions so we multiply across the numerators and we multiply across the denominators.

So we have 3 × 2 which is 6 and 8 × 1 which is 8. Since 6/8 is not in lowest terms, we divide the numerator and the denominator by the greatest common factor of 6 and 8 which is 2 and we get the equivalent fraction 3/4.

Therefore, 3/8 divided by 1/2 is 3/4.

The interior angles in a regular polygon are 140 degrees. How many sides has the polygon? it could be something to do with s=(n-2) x 180

Answers

Yes, it certainly could !  When you first noticed that formula in a book, or when it was given to you in class, did you also notice or learn what it means ?

It means
"The sum of all the interior angles in a polygon" = (number of sides - 2) x 180.

Triangle ........ 3 sides ... (3 - 2) = 1 x 180 = 180° degrees ... 60° each if regular
Quadrilateral . 4 sides ... (4 - 2) = 2 x 180 = 360° degrees ... 90° each if regular
Pentagon ...... 5 sides ... (5 - 2) = 3 x 180 = 540° degrees ... 108° each if regular
Hexagon ....... 6 sides ... (6 - 2) = 4 x 180 = 720° degrees ... 120° each if regular
Sevenagon ... 7 sides ... (7 - 2) = 5 x 180 = 900° degrees ... 128 and 4/7 each if regular
Octagon ........ 8 sides ... (8 - 2) = 6 x 180 = 1080° degrees ... 135° each if regular
Nonagon ....... 9 sides ... (9 - 2) = 7 x 180 = 1260° degrees ... 140° each if regular

The sum of the three interior angles of a triangle is 180 degrees.(there can be more than 1 answer)
please help

a.) x · y · z = 180°
b.) x + y + z = 180°
c.) 3a = 180°
d.) a + 55° + 36° = 180°
e.) x³ = 180°

Answers

It can be b), c) and d).

b) because it says the sum of three angles — this one’s the most obvious, as we can look at x, y and z as three different angles that sum up to 180.

c) works because 3a is, in essence, a + a + a, which we can look at as the sum of 3 angles that adds up to 180.

d) because we already have 2 angles, and “a” is just an unknown angle. It all sums up to 180.

a) and e) dont work because they involve multiplying (x*y*z and x*x*x) and the problem says we need to look for the sum of angles, not the product. :)

12 divided by 8 into a mixed number

Answers

Hi there, to turn a fraction into a mixed number we divide the numerator by the denominator, write down the whole number, and then right down the remainder. In this case, we divide the numerator which is 12 and 8 which is the denominator which is 8, 12 divided by 8 equals 1.5, 1 will be the whole number, 4 will be the numerator, and 8 will be the denominator. So, we get 1 4/8. Therefore, 12/8 as a mixed number is 1 4/8.

-1,-4,-7,-10 write an equation to find the nth term of each sequence. Then find a24

Answers

Answer:

\boxed {a_(24) = - 70}

Step-by-step explanation:

According to the following pattern sequence (-1, -4, -7, -10 ), it is Arithmetic Sequence, because every negative number is subtracted by 3. So, to find the 24th term, you need to use the Arithmetic Sequence Formula and solve to find the 24th term:

a_(n) = a_(1) +  (n - 1) d

a_(n): nth term in the sequence

a_(1): 1st term

n: term position

d: Common difference

-Apply to the formula:

a_(24) = -1 - 3 (24 - 1)

a_(n) = a_(24)

a_(1) = -1

n = 24

d = -3

-Solve:

a_(24) = -1 - 3 (24 - 1)

a_(24) = -1 - 3 (23)

a_(24) = -1 - 69

\boxed {a_(24) = - 70}

Therefore, the 24th term is -70.

Final answer:

The nth term of the sequence is given by the formula nth term = -1 + (n-1)(-3), resulting in a24 (the 24th term) being -70.

Explanation:

To find the nth term of any arithmetic sequence, you can use the formula: nth term = a + (n - 1)d where a is the first term and d is the common difference. In the given sequence -1, -4, -7, -10, the first term (a) is -1 and the common difference (d) is -3 (because each term is 3 less than the previous term).

So, the nth term formula for this sequence would be

nth term = -1 + (n-1)(-3)

To find the 24th term of the sequence (a24), you would substitute n with 24. So, a24 = -1 + (24-1)(-3) = -70.
