Answer:

[tex]\sqrt{85}[/tex] /2

Step-by-step explanation:

lets find hypotenuse( longest side) first

let other two samller sides be a and b and hypotenuse be c

pythagorsd theorem

a^2 + b^2 =c^2

9^2 + 2^2 =c^2

81 + 4=c^2

85 =c^2

[tex]\sqrt{85}[/tex] =c

take theta as reference angle

cosec theta=hypotenuse/opposite

=[tex]\sqrt{85}[/tex] / 2

Answer:

Answer is B. CSC ∅ = √85 /2

Step-by-step explanation:

CSC = 1 / Sin ∅

So first find Sin ∅ = 2 / √ 85 and then substitute in the formula

And oh, in case you're wondering, √ 85 is the hypotenuse side which you find like this:

√ 9² + 2²

√ 81 + 4

√ 85

Answer:

Step-by-step explanation:

3x² + 6x + 2 = 0

Quadratic Formula is:

x = -b ± √b²- 4ac/2a

So...

Δ = b² - 4ac = 6² - 4.3.2 = 12

x = -6 ± √Δ/2.3 = -6 ± √12/6

x' = -6 + √12/6 ≈ -0,4227

x'' = -6 - √12/6 ≈ -1,5774

S = { -0,4227 , -1,5774 }

Answer:

P(N) = 5/14

Step-by-step explanation:

Find P(N) by finding the probability of getting a noisemaker.

There are 42 items in total, and 15 are noisemakers. Find the probability by dividing 15 by 42:

15/42

Simplify:

5/14

So, P(N) = 5/14

Answer:

D: (2, -3)

Step-by-step explanation:

We have;

y = 3x - 9 - - - (1)

y = -2x + 1 - - - (2)

By substitution method, from eq 1, we see that: y = 3x - 9

Thus,let's put 3x - 9 for y in eq 2;

3x - 9 = -2x + 1

Rearranging to get;

3x + 2x = 9 + 1

5x = 10

x = 10/5

x = 2

Thus;

y = 3(2) - 9

y = 6 - 9

y = -3

Thus,the solution (x, y) = (2, - 3)

Step-by-step explanation:

[tex] \frac{1}{4} r+ 2 = 10[/tex]

[tex] \frac{r}{4} + 2 = 10[/tex]

[tex] \frac{r}{4} = 10 - 2[/tex]

[tex] \frac{r}{4} = 8[/tex]

[tex]r = 8 \times 2[/tex]

Answer:

Number of hour work per shift = 11 hour per day

Amount paid for one shift = Rs 198

Step-by-step explanation:

Given:

Amount pay per hour = Rs 18

Shift time = 12 h  to 23 h

Find;

Number of hour work per shift

Amount paid for one shift

Computation:

Number of hour work per shift = 23:00 - 12:00

Number of hour work per shift = 11 hour per day

Amount paid for one shift = Number of hour work per shift x Amount pay per hour

Amount paid for one shift = 11 x 18

Amount paid for one shift = Rs 198

Answer:

I dont know for sure, but maybe try B

Step-by-step explanation:

Answer:

720

Step-by-step explanation:

x÷18=40

x=18•40

x=720

Answer: The answer is D

Step-by-step explanation:

You add z to the other side then it will cancel out which then it would be (w+z)  and then you times it by 2 by both sides which would be 2(w+z) and then you would subtract x from both sides which will be 2(w+z)-x

Answer:

There will be no difference in pain ratings from people protected by her spell and people who aren't protected by her spell.

Step-by-step explanation:

The claim in this scenario is the alternative hypothesis, which is what we wish to test ; the alternative hypothesis is thus ; people who are protected by spell will rate their pain as a result of cruciatus curse as less severe than the average person who does not use her protection spell ;

As we know, the null hypothesis is the opposite of the alternative hypothesis and the initial truth, which is ;

The average pain felt by both the user of the pain protections spell and those who do not feel the same amount of pain.

Answer:

  (-3/4, 3)

Step-by-step explanation:

I find it easier to determine the intercepts when the equation is in standard form:

  4x -y = -6

The x-intercept is found where y=0:

  4x = -6   ⇒   x = -6/4 = -3/2

The y-intercept is found where x=0:

  -y = -6   ⇒   y = 6

Then the midpoint is ...

  M = ((-3/2, 0) +(0, 6))/2 = (-3/4, 3)

Answer:

Answer:

5 times

Step-by-step explanation:

Using visual inspection, the bar of North HS is 5 times longer Than the bar of West HS.

The gtids are of equal size, West HS occupies one portion of the grid, while North HS occupies 5 portions of the grid

5 portions / 1 portion = 5

Hence, North HS according to the graph is 5 times West HS

Answer:

Alex is correct.

Step-by-step explanation:

In order for Alex to get to $0, meaning he owes the bank nothing, he has to add 155 dollars to negative 155 dollars, because this means he has no debt left. The absolute value of -155 is 155 and if Alex pays the 155 dollars, he will not have to pay anything else to the bank.

Orthocenter is the best term to describes point R in the triangle UVW.

" Orthocenter is defined as intersecting point of the altitudes of the sides of the acute angle triangle."

According to the given figure,

In triangle UVW,

Ray VR perpendicular to UW

Ray UR perpendicular to VW

Ray WR perpendicular to UV

Altitudes of side  ( UV , VW, and WU) of triangle UVW intersect at

point R.

As per the definition of orthocenter , point R represents orthocenter.

Hence, orthocenter is the best term to describes point R in the triangle UVW.
