Which expressions are equivalent to 1 divided m/6? Check all that apply
jenyasd209 [6]

Answer:

option A, option C, option D

Step-by-step explanation:

a) 1 ÷ m/6

can be written as

\frac{1}{1}÷ \frac{m}{6}

b) sides in (m/6) will change if both has to multiply

c) 1 ÷ m/6

can be written as

1 * 6/m

1(\frac{6}{m}) and wont make change to answer. so matches with the question.

d)

1 ÷ m/6

1 * 6/m

1 * 6 * \frac{1}{m}

6 * \frac{1}{m}

6 ÷ m ..therefore true

e)

1 ÷ m/6

1 * 6/m

6/m    ....does not match or can be converted to the following so wrong

  • Therefore A, C, D are correct and B and E is wrong.

The numerator of a fraction (which is in its simplest form) is 5 less than the denominator. If the numerator is multiplied by 2,
timama [110]
N = d - 5

2n/(d + 16) = n/d - 1/3 n/d
2n/(d + 16) = 2/3 n/d Divide by 2n
1 / (d + 16) = 1/3 d
Here's the tricky part.
d + 16 = 3d the two denominators are equal. the numerators are both 1.
16 = 2d
d = 8
so the numerator is d - 5
n = 8 - 5
n = 3

Let's see if it checks out.
n = 3
d = 8

2*3 = 6
8 + 16 = 24
New fraction 6/24 = 1/4
(3/8 - 1/3 ) = 1/8
3/8 - 1/8 = 1/4 so it checks with the original conditions put on it.

Triangle GHK has an area of 117cm2. Write and solve an equation to find the height of the triangle GHK
stellarik [79]

Answer:

h=58.5/b

Step-by-step explanation:

This isn't necessarily possible, unless you know the base, but I can solve it with what we have, understanding the answer will contain variables:

The formula for the area of a triangle is A=1/2bh

117=(1/2)bh

58.5=bh

h=58.5/b

I'm not sure if this is the answer you were looking for, but I hope it helps

What is the common ratio between successive terms in the sequence?
Cloud [144]

Question:

What is the common ratio between successive terms in the sequence?

27, 9, 3, 1

Answer:

common ratio = \frac{1}{3}

Step-by-step explanation:

In a geometric progression, the common ratio, r, is the ratio of a term in the sequence to a preceding term in that same sequence. In other words, the common ratio is found by dividing a term by the term just before it. For example, if the geometric sequence is:

a, b, c, d...

The common ratio is found by any of the following;

r = \frac{b}{a}        ----------(i)

r = \frac{c}{b}        -----------(ii)

r = \frac{d}{c}        ------------(iii)

Any of equations (i) through (iii) will give the common ratio of the sequence.

============================================================

Now, from the question, the given sequence is;

27, 9, 3, 1

To get the common ratio, just divide the second term (9) by the first term (27) i.e

r = \frac{9}{27} = \frac{1}{3}

OR

You can also divide the third term (3) by the second term (9). i.e

r = \frac{3}{9} = \frac{1}{3}

OR

You can choose to divide the fourth term (1) by the third term (3). i.e

r = \frac{1}{3}

Which ever adjacent terms you choose gives you the same result. Therefore, the common ratio of the given sequence is \frac{1}{3}
