Length in units:

Use phytogoras theorem or measure it by a ruler if your using a graph paper

AB = 5.65 units

AC = 5.83 units

CB = 1.41 units

Perimeter =5.65 + 5.83 + 1.41 = 12.89 units

Area = 1/2 * 1.41 * 5.65 = 3.98units

The price of a senior citizen ticket is $8 and the price of a student ticket is$ 10

Step-by-step explanation:

Let the cost of one seniors citizen ticket be x and student be y

First day:

10 seniors citizen tickets and 11 student for a total of $190.

10x + 11y = 190-----------------------------(1)

Second day:

$160 on the second day by selling 5 senior citizen tickets and 12 student tickets.

5x + 12y = 160---------------------------------(2)

Multiply eq(2) by 2

10x + 24y = 320----------------------------(3)

Subtract eq(1) from (3)

10x + 24y = 320

10x + 11y = 190

-----------------------------

0x + 13 y = 130

---------------------------

13y = 130

$y = \frac{130}{13}$

y = 10-------------------------------(4)

Substituting (4) in (2)

5x + 12(10) = 160

5x + 120 = 160

5x = 160-120

5x = 40

$x = \frac{40}{5}$

x = 8

If 2 dice are rolled at the same time, what is the probability of the 2 dice having the same face

statuscvo [17]

Total number of possible results of rolling 2 dice = 6 x 6 = 36

Total number of ways they can both show the same face = 6

Probability of showing the same face = 6/36 = 1/6 = 16 and 2/3 percent.

What are the restrictions for (x^2+10x+25)/(x^2-3x-28) 0,14 -4,7 0,7 4,7

nirvana33 [79]

The answer is -4,7

The denominator can't equal zero. Factor the denominator:
x^2 - 3x - 28=
(X - 7)(x + 4); next set each set of parentheses equal to 0;
x - 7 = 0; so x=7 is one value
x + 4 = 0; so x=-4 is the other
Remember, x = 7 and x= -4 make the denominator zero, which is a "restriction" because you can't divide by zero.
