Before reaction, total number of nitrogen atoms is 2, also the total hydrogen atoms is 6. After the reaction, still, we have the same number of nitrogen atoms as 2, and hydrogen atoms as 6. This therefore obeys the law of conservation of mass that during a chemical reaction, matter is neither created nor destroyed.

Step-by-step explanation:

m = 14, n = 12.5

m<L = (5m + 36)° = (5(14) + 36)°

L = 106°

m<p= (6n-1°)=(6x12.5-1°)

p=74°

m<Q = (4m + 50)° = (4(14) + 50)°

Q = 106°

k=360°-(106°+74+°106°)=360°-286°

k=74°

Answer:

108 cm^2

Step-by-step explanation:

rectangle   + 2  triangle = total area

L x W          + 2    *  1/2 base * height   = total area

(5x12)          + 2    *  1/2 * 12 * 4    = total area

  60              +   48    = 108 cm^2

Answer:

108 cm²

Step-by-step explanation:

To do:

1. find area of rectangle      2. find area of triangles       3. add them together

area of a rectangle = bxh = 5x12 = 60

area of triangle = (bxh)/2 = (12x4)/2 = 24

60+24+24=108

[tex]\text{Given that,}\\\\f(x) = 7x^2\\\\f'(x) = 7\cdot 2 x = 14x\\\\\text{At x = 12,}\\\\f'(12) = 14 \times 12 = 168[/tex]

Answer:

The rectangle:  L = 40 yards.   W = 5 yards

The square: The length and width are both 5 yards.

Step-by-step explanation:

Let L and W be the length and width of the rectangle.

Let l and w be the length and width of the square.

Area for each is:

Rectangle:  L*W

Square:       l*w

We are told that L*W + l*w = 225 yards^2

We are also told that

L = 8W

and that

l = W

Since the sides of a square are all equal, w is also W:  w=W

Summarizing and substituting:

L*W + l*w = 225 yards^2

(8W)*W + W*W = 225 yards^2

8W^2 + W^2 = 225 yards^2

9W^2  = 225 yards^2

W^2 = 25

W = 5 feet

---------------------

Therefore, since L = 8W , L = 40 yards.   W = 5 yards for the rectangle.

The square:  l=W, so l = 5 yards, and thus w=5 yards

--------------------------

Check:

Do a rectangle of 40' x 5' plus a square of 5' x 5' have a total combined area of 225 yards^2?

40yd x 5yd + 5yd x 5yd = 225 yards^2?

200 yd^2 + 25 yd^2 = 225 yards^2?

YES

Reason:

The confidence interval for the population proportion p is (0.34, 0.43)

This is equivalent to saying 0.34 < p < 0.43

We're 95% confident p is somewhere between 0.34 and 0.43

Both of these endpoints are smaller than 0.45, meaning that all of the proportions p in the interval are smaller than 0.45

So it's fairly reasonable to assume that less than 45% of the Floridian voters are democrats (since it seems to be between 34% and 43%). Keep in mind that there's always a margin of error with statistics, so we cannot say this with 100% certainty.

Yes, it is reasonable to claim that less than 45 % of Floridian voters are Democrats.

If the sample size is given to be n < 30, then for finding the confidence interval for the mean of the population from this small sample, we use a t-statistic.

Let the sample mean given as[tex]\overline{x}[/tex] and

The sample standard deviation s, and

The sample size = n, and

The level of significance = [tex]\alpha[/tex]

Then, we get the confidence interval in between the limits

[tex]\overline{x} \pm t_{\alpha/2}\times \dfrac{s}{\sqrt{n}}[/tex]

where, [tex]t_{\alpha/2}[/tex] is the critical value of 't' that can be found online or from tabulated values of critical value for a specific level of significance and degree of freedom n - 1.

The confidence interval for the population proportion p is given as (0.34, 0.43)

The balance in Hayden's savings account is $600.

Net worth is total assets less liabilities. Assets are items owned by a person that creates benefits in the future to the person. Liabilities are what are owed to another person.

Net worth = assets - liabilities

6760 = (2540 + 6000 + savings)  - (880 + 1500)

Answer:

Pink Trapezoid = 15

Green Cresent = 11

Step-by-step explanation:

The total weight of the mobile is 30.

Because the mobile is evenly balanced between both sides, and we know the diamonds weigh 2 each, we can use simple math tofind the values of the other shapes.

So the total weight (30) divided by the 2 sides = 15 on each side.

This means the pink trapezoid weighs 15 and the rigt side weighs 15.

So 15 - 2 - 2 = 11

So the green Crescent weighs 11.

in the question , we've been given a five sided figure , i.e. , a pentagon.

sum of angles of a pentagon = ( 5 - 2 ) × 180°

[tex]\implies \: 3 \times 180\degree \\ \implies \: 540\degree[/tex]

thus we can say that ,

angle sum property of pentagon states that the sum of all the angles of a pentagon equals 540°.

therefore ,

Step-by-step explanation:

[tex]125\degree + 117\degree + (x + 6)\degree + x + (x - 44)\degree = 540\degree \\ \\ 125\degree + 117\degree + x + 6\degree + x + x - 44\degree = 540\degree \\ \\ 204\degree + 3x = 540\degree \\ \\ 3x = 540\degree - 204\degree \\ \\ 3x = 336\degree \\ \\ x = \cancel\frac{336}{3} \\ \\ x = 112\degree[/tex]

To find :-

The value of x in the angles of Pentagon

Given :-

Here we have been provided 5 angles in Pentagon

x°, (x - 44)°, (x + 6)°, 125°, and 117°

Solution :-

We will find the value of x with the angle sum property.

Now, we will find the sum of angles of Pentagon

there is a formula

(n - 2) × 180°

n = no. of sides of above shape

here n = 5

(5 - 2) × 180°

3 × 180° = 540°

Now will add the above given angle in the diagram and put equal to 540°.

x° + (x - 44)° + (x + 6)° + 125° + 117° = 540° (angle sum property)

[tex]3x + 204{\degree} = 540{\degree} \\ 3x = 540{\degree} -204{\degree} \\ 3x = 336{\degree} \\ x = \frac{336{\degree}}{3} \\ x = 112{\degree}[/tex]

x = 112°

further we will find further 2 angles related to x.

x - 44 = 112 - 44 = 68°

x + 6 = 112 + 6 = 118°

Result :-

The all angles of Pentagon are

125°, 117°, 118°, 112°, and 68°.

Answer:

1200

Step-by-step explanation:

We’ll need a number that is evenly dividable by all three values: 8,12 & 15. We can develop the generic common multiple by multiplying all three numbers and get 1440. But is that the smallest common multiple? The quick and dirty way to factor the number is to divide it by it’s various elements and see what works. In this case 1440/12=120 which is the smallest common multiple of the three numbers. The smallest length is therefore 120.
