Answer:

1/12

Step-by-step explanation:

Out of 16, 4 can’t be chosen which leaves 12 to choose from, Itzhak being ONE of them.

So that’s one out of twelve (1/12)

Answer:

1/12

Step-by-step explanation:

subtract the four soloists who can't be chosen from the total musicians

16-4=12

Itzhak is one person out of 12 who could be chosen to speak

Also the question is annoying because nobody calls an orchestra with 16 people a "16 piece orchestra"

Answer:

$1.\ 8p = 64, p =8$

$2. -\dfrac{w}{4} = 8, w = -32$

$3. -5c = -20, c =4$

$4.\ 9m=45, m = 5$

$5. \dfrac{b}{25} = -3, b =-75$

$6. \dfrac{d}{-2} = 20, d=-40$

Step-by-step explanation:

Now let us see the detailed solution of each part:

Part 1:

$8p -15 = 49\\\Rightarrow 8p =49+15\\\Rightarrow 8p = 64\\\Rightarrow p =8$

Part 2:

$\dfrac{-w}{4}+18=26\\\Rightarrow \dfrac{-w}{4} = 26-18\\\Rightarrow \dfrac{-w}{4} = 8\\\Rightarrow -w = 8 \times 4\\\Rightarrow w =-32$

Part 3:

$-5c-15=-35\\\Rightarrow -5c = -35 +15\\\Rightarrow -5c = -20\\\Rightarrow c = 4$

Part 4:

$9m +10=55\\\Rightarrow 9m =55-10\\\Rightarrow 9m =45\\\Rightarrow m =5$

Part 5:

$\dfrac{b}{25}-83=-86\\\Rightarrow \dfrac{b}{25} = -86 +83\\\Rightarrow \dfrac{b}{25} = -3\\\Rightarrow b = -75$

Part 6:

$\dfrac{d}{-2}+85=105\\\Rightarrow \dfrac{d}{-2} = 105-85\\\Rightarrow \dfrac{d}{-2} = 20\\\Rightarrow d=20 \times -2\\\Rightarrow d =-40$

According to the triangle proportionality theorem, which proportion is correct?

vfiekz [6]

According to triangle proportionality theorem:

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

And in the given triangle, MN parallel to BC, So MN divided the two sides in proportion, that is

$\frac{MB}{AM}=\frac{NC}{AN}$

Correct option is the third option .

Find the solution set of the inequality: 8x+2>34

Sholpan [36]

8x + 2 > 34

-2 -2

8x > 32

8x (÷ 8) > 32 (÷ 8)

x > 4

so x can equal any number from 5 and infinity

Hope I helped !!! :)
