A park has two biking trails. Tailand Trail is 5 3/10 long. Mayland Trail is 2 4/5 miles long. How much longer is Tailand Trail than Mayland Trail.

Answer:

8 pigs

Step-by-step explanation:

Since every animal has only 1 head, a total of 26 heads suggests that there are 26 animals in total.

Suppose all animals are chickens.

Total no. of feet = 26 chickens × 2 feet

                           = 52 feet

Difference in total no. of feet = 68 feet - 52 feet

                                                = 16 feet

Difference in no. of feet each animal has

= 4 feet (a pig) - 2 feet (a chicken)

= 2 feet

∴ No. of pigs = 16 feet ÷ 2 feet

                      = 8 pigs

Answer:

\(z = 3 + i\) is complex as \(a,b\in \mathbb{R}\), \(b \neq 0\).

Step-by-step explanation:

A complex number comprehends all numbers of the form:

\(z = a+i\cdot b\), \(\forall \,a,b\in \mathbb{R}\)

Where \(i = \sqrt{-1}\).

In other words, complex numbers are an extension of real numbers.

There is the following classification depending on what values of \(a\) and \(b\) exist:

Real - \(a \in \mathbb{R}\), \(b = 0\)

Complex - \(a,b\in \mathbb{R}\), \(b \neq 0\)  

Pure imaginary - \(a = 0\), \(b \neq 0\) (The term "nonreal complex" is a synonym for pure imaginary complex)

Let be \(z = 3 + i\), which is complex as \(a,b\in \mathbb{R}\), \(b \neq 0\).

The number contains both real and imaginary parts, hence it is classified as a complex number.

Complex numbers are square roots of negative numbers. They are represented using the letter "i".

Complex number is expressed as z = x + iy where:

Given the value 3+i, since the number contains both real and imaginary parts, hence it is classified as a complex number.

The length of time that it will take for each of the workout sessions would be: Plan A = 1.5 hours, and Plan B =  0.5 hours.

The length of the sessions can be obtained by first obtaining drawing a system of equations for the two cases. On Wednesday, we can represent the sessions as follows:

2A + 12B = 9 hours

On Thursday, we would have

5A + 3B = 9 hours

2A + 12B = 9  Eqn 1

5A + 3B = 9   Eqn 2

Multiply equation 2 by -4

2A + 12B = 9

-20A - 12B = -36

2A - 20A = 9 -36

-18A = -27

Divide both sides by -18

A = 1.5 hours

For B, substitute A in the first equation

2(1.5) + 12B = 9

3 + 12B = 9

12B = 9 - 3

12B = 6

Divide both sides by 12

B = 0.5

Then you can state that angle DEF is congruent to angle GHJ.

The postulate or theorem that allows you to state that angle DEF is congruent to angle GHJ is the Angle-Angle (AA) Postulate.

This postulate states that if two angles of one triangle are congruent to two angles of another triangle, then the third pair of angles must also be congruent.

In this case, if you have two triangles, one with angles DEF and the other with angles GHJ, and

you know that angle D is congruent to angle G and angle E is congruent to angle H, then by the AA Postulate, you can conclude that angle F is congruent to angle J.

No, the rank of the product of two n by n square matrices A and B, denoted as AB, cannot be less than n-1 if both A and B have ranks of n-1.

According to the Rank-Nullity theorem, for any matrix M, the sum of its rank and nullity is equal to the number of columns in M. In this case, the number of columns in AB is n, so the sum of the rank and nullity of AB must be n.

If rank(A) = rank(B) = n-1, it means that both A and B have nullity 1. The nullity of a matrix is the dimension of its null space, which consists of all vectors that get mapped to the zero vector when multiplied by the matrix. Since both A and B have rank n-1, their null spaces consist only of the zero vector.

Now, considering AB, if the rank of AB were less than n-1, it would mean that the nullity of AB is greater than 1.

However, this would violate the Rank-Nullity theorem since the sum of the rank and nullity of AB must be n, which is the number of columns.

Therefore,  if rank(A) = rank(B) = n-1, the rank of AB cannot be less than n-1.

Step-by-step explanation:

(a) Let's start with the first pool. It has 3650 liters of water. For every minute, 27 liters are being drained. Thus, we can write its equation as 3650 liters - 27 liters per minute = end amount of liters. If we write minutes as m, we can say 3650-27m is our expression. Similarly, for the second one, we have 4166-39m as our answer

(b) For this, we just have to make the two expressions equal, so

4166-39m = 3650-27m

The solution is:

(a)

Amount of water in the first pool (in liters) = 3650 liters - 27 liters per minute * x minutes

Amount of water in the second pool (in liters) = 4166 liters - 39 liters per minute * x minutes

(b)

3650 liters - 27 liters per minute * x minutes= 4166 liters - 39 liters per minute * x minutes

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here, we have,

(a) With x being the minutes after which you want to calculate the amount of water in the pool, to calculate this amount of water you must subtract the water drained from the initial amount of water that the pool contains.

Knowing that, for example, the water from the first pool drains at a rate of 27 liters per minute, then after x minutes, the total water drained will be 27 liters per minute * x minutes. Then:

Amount of water in the first pool (in liters) =  3650 liters - 27 liters per minute * x minutes

Reasoning in the same way:

Amount of water in the second pool (in liters) = 4166 liters - 39 liters per minute * x minutes

(b)  Now want to know when the two pools would have the same amount of water.  If they have the same amount of water then you can express:

Amount of water in the first pool = Amount of water in the second pool

Replacing the expressions found in (a):

3650 liters - 27 liters per minute * x minutes= 4166 liters - 39 liters per minute * x minutes

Answer:

Step-by-step explanation:

The formula you need for this is

\(A(t)=P(1+\frac{r}{n})^{nt\) where

A(t) is the amount after a certain number of years has gone by,

P is the initial deposit,

r is the interest rate in decimal form,

n is the number of compoundings done per year, and

t is the amount of time in years.

For us,

A(t) = 11900

P is 250

r is .048

n is 12 (there are 12 months in a year)

t is our unknown. Filling in:

\(11900=250(1+\frac{.048}{12})^{(12)(t)\) which simplifies a bit to

\(11900=250(1_.004)^{(12t)\) . Now we'll divide both sides by 250:

\(47.6=(1.004)^{12t\) and then take the natural log of both sides to bring that t down out front:

\(ln(47.6)=ln(1.004)^{12t\) and then

ln(47.6) = 12t ln(1.004). Now divide both sides by ln(1.004) to isolate the 12t:

967.6383216 = 12t and divide both sides by `12 to get

t = 80.6 months which is 6.7 years

Answer:

\(x=42.5^o\)

Step-by-step explanation:

Notice that this is an isosceles triangle, so the angles opposite to the sides of equal length (40 units) must be equal. That means that angleD = angleE

Then using the rule for addition of interior angles of a triangle equal to 180, we can write:

angleD + angleE + angleF = 180 degrees

x + x + 95 = 180

2 x = 180-95

2 x = 85

x = 85/ 2

x = 42.5 degrees

Answer:

42.5

Step-by-step explanation:

Side EF = 40

Side DF = 40

that means it is a equilateral triangle so:

Angle ∠E = Angle ∠D (which is x)

(180-95) / 2

= 42.5

answer:

y = -10

Step-by-step explanation:

make both equations look like y =

2x-3y=21 -> -3y= -2x+21 -> y = (-2x+21)/-3 -> y = 2/3x - 7

-6x + 2y = 7 -> 2y = 6x + 7 -> y = 3x + 7/2

now make the equations equal to each other (since they both equal y)

get x

2/3x - 7 = 3x + 7/2

-7 -7/2 = 3x - 2/3x

-14/2 -7/2 = 9/3x - 2/3x

-21/2 = 7/3x

(3/7) -21/2 = x

x = (3/7) -21/2

x = - 63/14

x = - 9/2

put it back in an equation to get y

y = 3x + 7/2

y = 3(-9/2) + 7/2

y = -27/2 + 7/2
