The number replaced by the question mark would be 1, because 12/1=12, and 12*1 is 12. Hope this helped! ^_^

The answer is 1.
Because 12/1 equals 12 and 12 x 1 equals 12
so that explains the right answer.

Out of a class of 150 students, two-fifths opted for German classes and one-third opted for Italian classes. The remaining opted

Yuliya22 [10]

Fraction of students that opted for French = $\frac{4}{15}$

The total number of students = 150

Fraction of students that opted for German = $\frac{2}{5}$

Fraction of students that opted for Italian = $\frac{1}{3}$

Fraction of students that opted for French = 1 - Fraction of students that opted for German - Fraction of students that opted for Italian

Fraction of students that opted for French = $1-\frac{2}{5} - \frac{1}{3}$

Fraction of students that opted for French = $\frac{15-6-5}{15}$

Fraction of students that opted for French = $\frac{4}{15}$

Find the 7th term 18,6,2…

Veseljchak [2.6K]

If we look at the series, one third of the current term gives the numerical value of the next term.

If we need to express it algebraically, we can write the following equation.

$a_{n+1}=\frac{a_{n}}{3}$

Therefore, our common multiplier can be found as follows. Because this sequence is a geometric sequence.

$\frac{a_{n+1}}{a_{n}} =r=\frac{1}{3}$

In geometric sequences, any term can be written in terms of the first term. Below is an example.

$a_{n}=a_{1}.r^{n-1}$

Since we know the numerical values of the first term and the common factor of the series, we can easily find the seventh term.

$a_{7}=a_{1}.r^{7-1}$
$a_{7}=18.(\frac{1}{3} )^6$
$a_{7}=\frac{2}{81}$

Please solve these 4 math equations...

vichka [17]

Answer:

1) x = 60° ; y = 70°

2) x = 50° ; y = 80°

3) x =110° ; y = 60°

4) x =60° ; y = 90°

Step-by-step explanation:

We have to find the interior angle y

= 180 - 120

= 60°

Now we have to find x

=180 - (60 + 50)

= 180 - 110

= 70°

We know that opposite angles are equal

So therfore y = 80°

x = 180 - 80 + 50

x = 180 - 130

x = 50°

According to the figure we see that x+y=180

Exterior angle = sum of two interior angle

So, x = 50 + 60

x = 110°

Now we substitute in the x value

x + y = 180

110 + y = 180

y = 180 - 110

y = 70°

Opposite angles are equal

x = 60°

The figure is a right angle triangle

So,

y =90°

7800 because it grows 300 per 2 hours so 3000 + 4800 = 7800
