The formula to find the number of chairs in each row is m = x ÷ n,
where
m - the number of chairs,
n - the number of rows,
x - the number of people.

If 60 people attend the meeting and each row has 4 chairs, there are 15 <span>rows.
</span>This is assumed using the above formula:
m = x ÷ n

If:
x = 60
m = 4

Then:
4 = 60 ÷ n
⇒ n = 60 ÷ 4
<span>⇒ n = 15</span>

Diamonds have a density of 3.5 LaTeX: \frac{g}{cm^3}g c m 3. How big is a diamond that has a mass of 0.10 g?

liubo4ka [24]

For this case we have that by definition, the density is given by:

$d = \frac {M} {V}$

Where:

M: It is the mass of the diamond

V: It is the volume of the diamond

According to the data of the statement we have:

$d = 3.5 \frac {g} {cm ^ 3}\\M = 0.10 \ g$

So the volume is:

$V = \frac {M} {d}\\V = \frac {0.10 \ g} {3.5 \frac {g} {cm ^ 3}}\\V = 0.02857\\V = 0.03 \ cm^3$

Thus, the volume of the diamond is approximately $0.03 \ cm ^ 3$

Answer:

$0.03 \ cm ^ 3$

Change each mixed number into an equal improper fraction a. 1 7/16, b. 11 5/9, c. 30 5/9, d. 10 10/13, e. 24 3/5, f. 129 1/2

elixir [45]

Answer:

a)

$\dfrac{23}{16}$

b)

$\dfrac{104}{9}$

c)

$\dfrac{275}{9}$

d)

$\dfrac{140}{13}$

e)

$\dfrac{103}{5}$

f)

$\dfrac{259}{2}$

Step-by-step explanation:

<em>" A fraction in which the numerator is greater than the denominator "</em>

We have to change each of the mixed fraction into improper fraction:

We know that the mixed fraction is converted into fraction as:

$a\frac{b}{c}=\dfrac{a\times c+b}{c}$

a)

$1\frac{7}{16}$ could be written as:

$=\dfrac{1\times 16+7}{16}\\\\=\dfrac{16+7}{16}\\\\=\dfrac{23}{16}$

b)

$11\frac{5}{9}$

$=\dfrac{11\times 9+5}{9}\\\\=\dfrac{99+5}{9}\\\\=\dfrac{104}{9}$

c)

$30\frac{5}{9}$

$\dfrac{30\times 9+5}{9}\\\\=\dfrac{270+5}{9}\\\\=\dfrac{275}{9}$

d)

$10\frac{10}{13}$

$\dfrac{10\times 13+10}{13}\\\\=\dfrac{130+10}{13}\\\\=\dfrac{140}{13}$

e)

$24\frac{3}{5}\\\\=\dfrac{24\times 5+3}{5}\\\\=\dfrac{100+3}{5}\\\\\dfrac{103}{5}$

f)

$129\frac{1}{2}\\\\\\=\dfrac{19\times 2+1}{2}\\\\=\dfrac{258+1}{2}\\\\=\dfrac{259}{2}$

Which is equivalent

arlik [135]

Answer:

D 8√(10) ^3x

Step-by-step explanation:

We have

sqrt(10) ^ (3/4x)

We can rewrite the sqrt as ^1/2

10 ^ (1/2) ^ (3/4x)

We know that a^b^c = a^(b*c)

10 ^(1/2 *3/4x)

10 ^(3/8 x)

The numerator is the power

The denominator is the root

8√(10) ^3x
