Answer:

10

Step-by-step explanation:

2-digit numbers are numbers that have two digit which they start from 10-99 so in this question i chose 10 as an example.

CuBr is soluble in pure water at a solubility of 0.2583 g/L, while CoBr₂ is soluble at a solubility of 7.50 × 10⁻⁶ g/L

Given,

The equation of reaction as; CuBr₂ → Cu²⁺ + 2Br⁻

In pure water, the Ksp of the solution is 6.27 * 10^-9

Ksp = [Cu²⁺] [Br⁻]²

Ksp = x³

Let's substitute and solve

x³ = 6.27 × 10⁻⁹

x = [tex]\sqrt[3]{6.27 * 10^{-9} }[/tex]

x = 0.0018

The molecular weight of CuBr₂ is 143.5 g/mol

The solubility of CuBr₂ is

0.0018 × 143.5 = 0.2583 g/L

The solubility in 0.0060M of CoBr₂

The equation of dissociation is given as

CoBr₂ → Co²⁺ + 2Br⁻

0.012         0         0

0                0.120   2 * 0.0060 = 0.012M

The dissociation of copper bromide is

CuBr₂ → Cu²⁺ + Br⁻

c                 0         0.012

c - s             s          s + 0.012

The Ksp of this reaction is

[Ksp] = [Co²⁺] [Br⁻]

The Ksp of CuBr₂ = 6.27 × 10⁻⁹

6.27 × 10⁻⁹ = s(s + 0.012)

s + 0.012 = 0.012

0.012 > > > s

6.27 × 10⁻⁹ = s × 0.012

s = 6.27 × 10⁻⁹ / 0.012 = 5.225 × 10⁻⁷ mol / l

Let's convert this into g/L

s =  5.225 × 10⁻⁷ × 143.5 = 7.50 × 10⁻⁶ g/L

Therefore,

The solubility of CuBr in pure water is 0.2583 g/L and the solubility in CoBr₂ is 7.50 × 10⁻⁶ g/L

The number of steps per second that a runner takes is not typically called the stride rate.

Stride rate is a measurement of how frequently a person makes steps when walking or jogging. It is typically expressed in steps per minute and is calculated by dividing the total number of steps taken by the time it takes for each step to be completed. A person is often traveling faster if they have a greater stride rate. Numerous variables, such as a person's height, leg length, and muscular strength, can influence stride pace. The kind of exercise being done and the surface on which a person is walking or jogging might also have an impact. People may assess their development and modify their training plan to increase their speed and efficiency by keeping an eye on their stride rate.

The probability that suits of cards are spades, hearts, and spades is 39/850 or 0.046.

According to the give question.

Three cards are drawn from a standard deck of cards without replacement.

Since,

The total number of cards in a standard deck = 52

Total number of spade cards = 13

Total number of heart cards = 13

Now,

The probability of getting first card as a spade card = 13/52 = 1/4

The probability of getting second card as heart card = 13/(52 -1)     (cards are drawn without replacement)

                                                                                        = 13/51

The probability of getting third card as a spade card = (13 - 1)/52 -2

                                                                                        = 12/50

                                                                                        = 6/25

Therefore, the probability that suits of the cards are spades, hearts, spades

= 1/4 × 13/51 × 6/25

The required three consecutive numbers are 35, 36, 37

Let the three consecutive numbers as per the questions are x , x+1 , x+2

Since, According to the question, the product of these three consecutive numbers are 46620

Therefore, we can write

x ( x+1 )( x+2 ) = 46620

x([tex]x^{2}[/tex] + 2x + x + 2 ) = 46620

[tex]x^{3}[/tex]+ [tex]2x^{2}[/tex] + [tex]x^{2}[/tex] + 2x = 46620

Now, [tex]x^{3}[/tex] + [tex]2x^{2}[/tex] + [tex]x^{2}[/tex] + 2x - 46620 = 0

      [tex]x^{3}[/tex] + [tex]3x^{2}[/tex] + 2x - 46620 = 0

After factorization, we get

    ( x- 35 )( [tex]x^{2}[/tex] + 38x + 1332 ) = 0

x - 35 = 0 Since ( [tex]x^{2}[/tex] + 38x + 1332 ) will always be a positive number

Therefore, x = 35

The dimensions of the garden with the largest area she can enclose is  24×14 square yards.

We know very well that the area (A) of the rectangle is given by =Length ×Breadth

The maximum of y=ax²+bx occurs at x = -b/2a

Let assume the  length and width of the garden be L and W respectively.

We have given some information like my friend is using same type of fencing  for three sides and different type of fencing on the remaining side.

Rate of cedar fencing is $17/yard

So, we can say that she has to pay for cedar fencing = 17W

Rate of cheaper metal fencing is $7/yard

Then she has to pay for metal fencing = 7W+7*2L = 7W+14L

Then according to given condition, total cost paid by my friend is $672.

It means sum of cost of cedar fencing and cost of cheaper metal fencing is $672.

=>17W+7W+14L = 672

=>24W+14L = 672

=>12W+7L = 336

=>7L = 336-12W

=>L = (336-12W)/7

Then the area of the rectangular garden is given by,

A = L×W

So, here  after comparison we got that a = -12/7 and b = 48

Then maximum of W occurs at,

W = -48/(2×(-12/7)) = (48×7)/(2×12) = 336/24 = 14

Then maximum width = 14 yards

then length (L) = (336-12×14)/7 = 168/7 = 24 yards

The standard deviation of days Spongebob needs to be in the office hour is 3.29.

First, we must find all probability distribution. Keep in mind, total probability is always equal to 1. So,

∑P(X) = 1

∑P(X) = P(X=3) + P(X=6) + P(X=7) + P(X=12)

1 = 0.16 + 0.2 + P(X=7) + 0.36

1 = 0.72 + P(X=7)

P(X=7) = 1 - 0.72

P(X=7) = 0.28

Next, to find standard deviation (σ) we can use this formula,

σ = [tex]\sqrt{\sum X^2\times P(X) - (\sum X\times P(X))^2[/tex]

= [tex]\sqrt{(3^2\times 0.16+6^2\times 0.2+7^2\times 0.28 + 12^2\times 0.36)-(3\times 0.16+6\times 0.2+7\times 0.28+12\times 0.36)}[/tex]

%, which is a relative figure used to denote hundredths of any amount. Since one percent (symbolized as 1%) is equal to one tenth of anything, 100 percent stands for everything, while 200 percent refers to double the amount specified.

The word percentage comes from the Latin adverb per centum, which means "by the hundred." In the 16th century, the Latin phrase made its way into English. Later, it was shortened to percent and ended with a period. Later, the period was eliminated, and the two parts were combined to create the current one-word form of percent.

We must figure out what proportion of the overall grade each grade corresponds to in order to answer this challenge. Therefore:

85 times 30%, or 85 times 30 per 100, equals 25.5%.

tests = 72*20% = 72*20/100 = 14.4%

exam = 61*50% = 61*50/100 = 30.5%

The two points in which the line y = 4x - 1 passes are:

(2.19, 7.76) and (3,11).

The format of the linear function is given by:

y = mx + b.

The linear function is defined taking a pair of points, and then:

For the first line, the two points are:

(1,3) and (2,7).

The slope is:

m = (7 - 3)/(2 - 1) = 4.

Hence:

y = 4x + b.

When x = 1, y = 3, hence the intercept b is obtained as follows:

3 = 4 + b

b = -1.

Then the first line is:

y = 4x - 1.

For the second line, the points are:

(2,7) and (6,2).

Hence the slope is of:

m = (2 - 7)/(6 - 2) = -5/4 = -1.25.

Then:

y = -1.25x + b.

When x = 2, y = 7, hence the intercept b is obtained as follows:

7 = -1.25(2) + b

b = 10.5.

Hence the second line is:

y = -1.25x + 10.5.

The x-coordinate of the intersection is given as follows:

4x - 1 = -1.25x + 10.5

5.25x = 11.5

x = 11.5/5.25

x = 2.19.

The y-coordinate of the intersection is:

y = -1.25(2.19) + 10.5 = 7.76.

Another point in which the line y = 4x - 1 passes is:

y = 4(3) - 1 = 11.

we can see that the cofficient are proportional to each other

[tex]\frac{x_{1}}{x_{2} } =\frac{y_{1}}{y_{2} } = \frac{z_{1}}{z_{2} }[/tex]

= 1/2

Thus, the equation must be 3x + 6y = 22 & 6x +12y = 44.
