What is the surface area

Mathematics

Bear in mind that the area of a "parallelogram" is base * height.

notice the picture, the front and back parallelograms, have an altitude/height of 3 cm, and  a base of 8 cm, so the area of one of those two is 3*8.

as far as the left and right parallelograms, they have a base of 7 cm, but the altitude is also 3 cm, so the area of one of those is 3 *7.

bear in mind the altitude/height is the distance from the base to the top, and in this case is just 3 cm.

anyway, you have 4 parallelograms, get the area of each, add them up, and that's the surface area of the figure.

2(3*8) + 2(3*7).

¿se puede hacer un triangulo con las siguientes medidas:2cm ,3cm ,10cm? ayudenme es para mañana
dezoksy [38]

Não, não podemos fazer um triângulo com os comprimentos dos lados de 2 cm, 3 cm e 10 cm. Isso ocorre porque a soma de 2+3 < 10. (in english: No, we cannot make a triangle with the side lengths of measurement 2 cm, 3 cm, and 10 cm. This is because sum of 2+3 < 10).

<h3>What is triangle inequality theorem?</h3>

Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.

Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,

(a+b) > c\\(b+c) > a\\(c+a) > b

Now, for this case, the sides given are:

  • a =2 cm,
  • b = 3 cm,
  • and c = 10 cm

But we see that:

a+ b = 5 cm which is < c which is of 10 cm.

Thus, these lengths don't satisfy the triangle inequality theorem, and therefore, cannot be sides of any triangle.

Let f(x) = |x|, ????(x) = 2f(x), and h(x) = 1 / 2 f(x) for any real number x.
SashulF [63]

Answer:

g(x) = 2|x|

h(x) = \frac{1}{2}|x|

Step-by-step explanation:

If you have g(x)=2f(x) and h(x)=\frac{1}{2}f(x), you can rewrite the expressions in terms of |x| as the following:

- For g(x)=2f(x) you have:

g(x) = 2|x|

-For h(x)=\frac{1}{2}f(x), you have:

h(x) = \frac{1}{2}|x|

a hockey season ticket holder pays 72.48 for her tickets plus 6.00 for a program each game each game a second person pays 18.08
tiny-mole [99]
If <span>I understand the question correct, the hockey season ticket holder paid $72.48 for all of the tickets at once, and then $6.00 for each game thereafter. The second person pays $18.08 for a ticket per game.

So then let g = the number of games. The problem can be written as a system of equations:

Person 1 = 72.48 + 6g
Person 2 = 18.08g

We are looking for when the number of games for both are the same. To do this, just set them equal to each other and solve for g.

72.48 + 6g = 18.08g
Subtract 6g:
72.48 = 12.08g
Divide by 12.08:
g = 6

So after 6 games, the two would have paid the same price.

Answer:

Th three consecutive integers are:

-17, - 16 , - 15

Step-by-step explanation:

Let the consecutive integers are:

x

x + 1

x + 2

According to given condition:

x + x + 1 + x + 2 = -48

Adding like terms

3x + 3 = -48

Subtracting 3 from both sides

3x = -48 - 3

3x = -51

Dividing by 3 on both sides

x = -51/3

x = - 17

So the three consecutive integers will be:

x = -17

x + 1 = -17 + 1 = -16

x + 2 = -17 + 2 = -15

I hope it will help you!
