Answer: the perimeter is 214. AB's half is 32.5 and BC's whole is 65

Step-by-step explanation: 10x-5 and 12x-26 are equal, as shown by the marks on their lines, so we can set them equal to each other to solve for x. when solved x=7. then plug 7 into each equation to get 65. lastly add up 84+65+65 to get 214.

the total attendance at a concert in a theater hall was 1500, of this total 400 were children,850 were women , and the remaining

AleksandrR [38]

Answer:

Below!

Step-by step explanation:

We know that:

400 + 850 + m = 1500

Solution of Question A:

Percent of children: Total children/Total attendance

=> 400/1500
=> 4/15
=> 0.27 (Rounded to nearest hundredth)
=> 0.27 x 100
=> 27%

Hence, the percent of children is about 27%.

Solution of Question B:

Percent of women: Total women/Total attendance

=> 850/1500
=> 85/150
=> 17/30
=> 17/30 x 100
=> 17/3 x 10
=> 170/3
=> 56.67%

Hence, the percent of women is 56.67%.

Solution of Question C:

400 + 850 + m = 1500
=> 1250 + m = 1500
=> m = 1500 - 1250
=> m = 250

Percent of men: Total men/Total attendance

=> 250/1500
=> 1/6
=> 0.17 (Rounded to nearest hundredth)
=> 0.17 x 100
=> 17%

Hence, the percent of men is about 17%

Hoped this helped.

Rewrite this standard form quadratic equation into vertex form by completing the square. Upload your work here to show your thin

Alex787 [66]

Solution :

Given the equation :

$y = x^2 - 6x+3$

$y=1(x^2 - 6x +n)+3$

$n = \left(\frac{b}{2}\right)^2$

$n = \left(\frac{6}{2}\right)^2$

n = 9

$y=1(x^2 - 6x +9-9)+3$

$y=1(x^2 - 6x +9)-9+3$

$y=1(x-3)^2- 6$

Therefore the vertex form of $y = x^2 - 6x+3$ is $y=1(x-3)^2- 6$ .

The functions below represent the amounts of water released from two reservoirs over x weeks:

solong [7]

Answer:

h(x) = -2x^2 -x +3
Reservoir A releases the same amount of water as Reservoir B over 1 week

Step-by-step explanation:

Given:

f(x) = x^2 -7x +5

g(x) = 3x^2 -6x +2

h(x) = f(x) -g(x)

Find:

h(x)

h(1)

Solution:

The expression for h(x) is found by evaluating its definition:

h(x) = (x^2 -7x +5) -(3x^2 -6x +2)

h(x) = x^2(1 -3) +x(-7 -(-6)) +(5 -2)

h(x) = -2x^2 -x +3

Then h(1) is found by substituting 1 for x:

h(1) = -2(1^2) -(1) +3 = -2 -1 +3

h(1) = 0 . . . . difference in release amounts after 1 week is 0

The true statements are ...

h(x) = -2x^2 -x +3
Reservoir A releases the same amount of water as Reservoir B over 1 week
