The area of a triangle is 1,440 cm2. The base of the triangle is 5 times the height. What is the height of the triangle? 12 cm 2

GarryVolchara [31]

The area of a triangle with base 'b' and height 'h' is given by the formula:

$A = \frac{1}{2} bh$

It is given that the area of a triangle is $1440 cm^2$ .

It is given that the base of the triangle is 5 times the height.

So, $b=5 \times h = 5h$

We have to determine the height of the triangle.

Since, $A = \frac{1}{2}bh$

$1440 = \frac{1}{2}(5h)h$

$1440 = \frac{1}{2}(5h^2)$

$1440 \times 2 = 5h^2$

$2880= 5h^2$

$\frac{2880}{5}= h^2$

$h^2=576$

So, $h=\sqrt{576}$

So, h = 24 cm

Therefore, the height of the triangle is 24 cm.

Option 2 is the correct answer.

A person participates in a state lottery by selecting six numbers from 1 through 51. If the six numbers match the six drawn by t

Licemer1 [7]

There are

$\dbinom{51}6=\dfrac{51!}{6!(51-6)!}=18,009,460$

total ways to draw any 6 numbers from the range 1 to 51, regardless of order.

Given 6 selected numbers that match those drawn by the lottery, there are

$6!=720$

ways of rearranging them. So the probability of winning 1st prize is

$\dfrac{720}{18,009,460}=\dfrac{36}{900,473}\approx0.0000399790$

Next, given 6 selected numbers of which 5 match those drawn by the lottery, there are

$5!=120$

ways of rearranging those 5 matching numbers. There are 46 remaining numbers that didn't get drawn, so the probability of winning 2nd prize is

$\dfrac{46\cdot120}{18,009,460}=\dfrac{12}{39,151}\approx0.0003065$

Select all expressions that can be subtracted from 9x to result in the expression 3x+5. −5+6x 5−6x 6x+5 6x−5 −6x+5

solong [7]

Step-by-step explanation:

1) 9x - (-5 + 6x) = 9x + 5 - 6x

Solving like terms

3x + 5

2) 9x - 5 - 6x

3x - 5

3) 9x - 6x + 5

3x + 5

4) 9x - 6x - 5

3x - 5

5) 9x - (-6x + 5)

9x + 6x - 5

15x + 5

2 and 4 are the expressions
