0.2 (20x + 10) = -42

Mathematics
1 answer:
Finger [1]3 years ago
4 0

Answer:

x = -11

Step-by-step explanation:

0.2(20x + 10) = -42

4x + 2 = -42                    Distribute 0.2 to the numbers in the paranthesis

4x = -44                          Add 2 to both sides

x = -11                              Divide 4 from both sides

Answer/Step-by-step explanation:

Quotient is simply the ratio of the first numerator to the second numerator:

Let's \frac{x_1}{y}\;and\;\frac{x_2}{y} are two fractions in same terms.

Thus, \frac{x_1}{y}\div\frac{x_2}{y} {Divided by a fraction is equal to multiplied by its reciprocal}

=\frac{x_1}{y}\times\frac{y}{x_2}

Quotient is simply the quotient of their numerators.

Example could be:

\frac{2}{7}\div\frac{3}{7}

\frac{2}{7}\times\frac{7}3}

\frac{2}{3}

2 is first numerator and 3 is the second numerator.

By [n][n] we denote the set {1,…,n}. A function f:[m]→[n] is called monotone if f(i) \leq f(j)f(i)≤f(j)whenever i &lt; ji
Dafna11 [192]

Answer:

There are a total of  { 6 \choose 3} = 20 functions.

Step-by-step explanation:

In order to define an injective monotone function from [3] to [6] we need to select 3 different values fromm {1,2,3,4,5,6} and assign the smallest one of them to 1, asign the intermediate value to 2 and the largest value to 3. That way the function is monotone and it satisfies what the problem asks.

The total way of selecting injective monotone functions is, therefore, the total amount of ways to pick 3 elements from a set of 6. That number is the combinatorial number of 6 with 3, in other words

{6 \choose 3} = \frac{6!}{3!(6-3)!} = \frac{720}{6*6} = \frac{720}{36} = 20

Given 2 circles: One with a diameter of 20 cm and another with a 50 cm, find the difference between the 2 areas. Hint: area= pi
Lelu [443]

Answer:

1648.5

Step-by-step explanation:

20cm radius - 10

50cm radius- 25

area = 3.14×10²

3.14×100

=314

area= 3.14× 25²

3.14×625

= 1962.5

1962.5

- 314

_________

1648.5
