1 answer:

3 0

Sup. < of 35 degree < = 145 degree <
comp. < of 35 degree < = 20 degree <
145-20=125 degrees

the answer is:

Which expression is equivalent to −1/ 12x−1 /3?

alexandr402 [8]

Answer:

$\frac{1}{12} (-x-4)$

Step-by-step explanation:

the expression we have is:

$-\frac{1}{12} x-\frac{1}{3}$

To find an equivalent expression, it would be helpful to express 1/3 so that it has a 12 in the denominator:

$\frac{1}{3}=\frac{4}{12}$

so we substitute this:

$-\frac{1}{12} x-\frac{4}{12}$

and now we have 1/12 in both terms :

$-\frac{1}{12}x-\frac{1*4}{12}$

so we can factor it (we take it out of each term: in the first we are left with -x and in the second with -4):

$\frac{1}{12} (-x-4)$

the equivalent expression is: $\frac{1}{12} (-x-4)$

The closest answer I can see you type is: 35/1.66666666

This is because you divide 21 by 18 which (if you divide 21 by 1.666666 you get 18) and whatever you do to 1 side, you do to the other, then you get 35/1.6666666

A child has a box full of colored building blocks. She will choose one block without looking. The odds against choosing a blue b

Mama L [17]

(a) A child has a box full of colored building blocks. She will choose one block without looking. The odds against choosing a blue block are 4/7. What is the probability of choosing a blue block?

Answer:

7/11 is the probability of choosing a blue block.

Step-by-step explanation:

We need the probability of choosing a blue block,

Odds:

The odds of an event is the ratio of the probability of an event to the probability of its complement. In other words, it is the ratio of favorable outcomes to unfavorable outcomes.

The odds against choosing a blue block are 4/7 means. In 11 chances, 4 events will happen in which blue block will not be chosen and 7 events will happen in which blue blocks will be chosen.

So, the probability of not choosing the blue block is 4/11.

Probability of choosing blue block: complement of 4/11 which is equal to 7/11.

(b) Amanda is playing a role-playing game with her friends. She will roll dice to determine if her character unlocks a treasure chest. The probability of her character unlocking the treasure chest is 13/20. Find the odds in favor of her character unlocking the treasure chest.

Answer:

The odds in favor of her character unlocking the treasure chest are 13/7.

Step-by-step explanation:

The probability of Amanda's character unlocking the treasure chest is 13/20.

It means, in 20 total chances, 13 times an event will happen where Amanda's character unlocks the treasure chest while the rest 7 times, her character would not open treasure chest.

Favorable events: 13

Unfavorable events: 7

Hence, the odds in favor of her character unlocking the treasure chest are 13/7.

lisa is ordering sand from the internet. On one site she found sand on sale for $2.25 per pound and on the second site she found

Anuta_ua [19.1K]

<h3>The better deal would be the the 5kg for $14 price.</h3><h3 /><h3>Why: 5kg is around 11 pounds, so if you bought the 11 pounds on the first site, it would be $24.75. So Lisa would save 10 dollars if she chose the second site.</h3><h3 /><h3>If this answer is correct, please mark it as Brainliest. :)</h3>

Which equation represents a parabola that has a focus of (0, 0) and a directrix of y = 4?

Ray Of Light [21]

Answer:

x2=−8(y−2)

Step-by-step explanation:

Parabola is a locus of a point which moves at the same distance from a fixed point called the focus and a given line called the directrix.

Let P(x,y) be the moving point on the parabola with

focus at S(h,k)= S(0,0)

& directrix at y= 4

Now,

|PS| = √(x-h)2 + (y-k)2

|PS| = √(x-0)2 + (y-0)2

|PS| = √ x2 + y2

Let ‘d’ be the distance of the moving point P(x,y) to directrix y- 4=0

d= |ax +by + c|/ √a2 + b2
d= |y-4|/ √0 + 1
d= |y-4| units.

equation of parabola is:

|PS| = d
√ x2 + y2 = |y-4|

Squaring on both sides, we get:

x2 + y2 = (y-4)2
x2 + y2 = y2 -8y + 16
x2 = - 8y + 16
x2 = -8 ( y - 2)

This is the required equation of the parabola with focus at (0,0) and directrix at y= 4.
