A smaller triangle is cut out of a larger triangle. The larger triangle is a right triangle with side lengths of 5 millimeters a
Genrish500 [490]

Options :

21 mm2

24 mm2

42 mm2

48 mm2

Answer: 24mm^2

Step-by-step explanation:

Given the following :

Side length of larger triangle:

Base = 5mm

Height = 12mm

Side length of smaller triangle :

Base = 4mm

Height = 3mm

Area of triangle :

0.5 × base × height

Area of larger triangle :

0.5 × 12mm × 5mm = 30mm^2

Area of smaller triangle :

0.5 × 4mm × 3mm = 6mm^2

Area of shaded region :

(Area of larger triangle - Area of smaller triangle)

(30mm^2 - 6mm^2) = 24mm^2

Four cards are shuffled and placed face down in front of you. Their faces (hidden) display the four elements: water, earth, wind
Licemer1 [7]

Answer:

probability of winning is\frac{2}{3}

Step-by-step explanation:

As it is given , 4 cards are available,  there are 4!  mean total possible way of ordering is 24  

following are the cases of loosing

1) first card is fire.

Thus there are 3! = mean 6 possible ways for particular ordering  to occur.

2) If wind is first card and Fire is second. Then, There are 2! = 2 ways to occur.

Hence, the probabiIity of losing is given as  = \frac{6+2}{24}=\frac{1}{3}

therefore probality of winning is 1 -\frac{1}{3}

probality of winning is\frac{2}{3}

△STR≅△LMN, SR=7b+8, and LN=11b−12. Find b and SR.
Goryan [66]

Given:

\Delta STR\cong \Delta LMN

SR=7b+8

LN=11b-12

To find:

The value of b and SR.

Solution:

We have,

\Delta STR\cong \Delta LMN                          (Given)

ST\cong LN                                  (CPCTC)

ST=LN

Substituting the given values, we get

7b+8=11b-12

7b-11b=-8-12

-4b=-20

Divide both sides by -4.

\dfrac{-4b}{-4}=\dfrac{-20}{-4}

b=5

Now,

SR=7b+8

SR=7(5)+8

SR=35+8

SR=43

Therefore, the value of b is 5 and the measure of SR is 43 units.
