if the rise is 16 and the run is 8, what is the slope

Answer:

Step-by-step explanation:

The statement is flipped, and saying different sayings.

Answer:

If n + 4 is odd,  then n is odd.

Step-by-step explanation:

Contrapositive statements negate the original statement and interchanges(flips) it.

So the negated statement would be ' If n is odd, then n + 4 is  odd'.

Then we interchange that statement so  ' If n is odd, then n + 4 is odd' becomes, ' if n + 4 is odd,  then n is odd.'

Answer:

14. 41

Step-by-step explanation:

I used Substitution.

3(2) - 2 = 4

Answer: EF = 29 units and KM = 22 units

Step-by-step explanation: For the first one, we just add EF and FG, x+14 and 14, and make it equal to EG, 2x+13. We then get x+28 = 2x+13, x = 15. EF = x + 14 and then sub in 15 for x to get 29.

For KM, same deal as the first one. KL and LM, 6 and 2x, equals to KM, 3x-2. 2x+6 = 3x - 2. x = 8. KM = 3x - 2. sub in 8 for x and then we get 22.

The standard form the Complex number having real part "a" and imaginary part"b" is a+ib.

Complex number:

Basically, a Complex number is made up of two numbers: a real number and an imaginary number. A+iB, where an is a real number and ib is an imaginary number, is a Complex number. A and B are real numbers.

As a result, a Complex number is just a straightforward way to describe the addition of two integers, a real number and an imaginary number. It is divided into two parts: a pure actual component and a pure fictitious part.

The value of the expression given as −26.6/−1 is 26.6

The expression is given as

−26.6

-----------

−1

Rewrite the above expression properly as follows

So, we have

−26.6/−1 or −26.6 ÷ −1

This is so because the expression is a quotient expression

So, we have

−26.6/−1

Express −26.6 as -13.3 - 13.3

So, we have the following equation

−26.6/−1 = (−13.3  −13.3)/−1

Expand the expression

So, we have

−26.6/−1 = (−13.3)/−1 + (−13.3)/−1

Evaluate the quotients in the above equation

So, we have

−26.6/−1 = 13.3 + 13.3

When the numbers 1-7 is put in the seven circles so that the numbers in each group of three circles connected with a straight line add up to 12 then the number 4 is kept at the center

Let say A , B , C , D , E  , F  & G are 7 numbers  from 1 to 7

& D is in center

So, A & G , B & F , C & E are opposite

A + D + G  = B + D + F  = C + D  + E

=> A + G = B + F = C + E

Adding all numbers

A + B + C + D + E + F + G  + 2D

( A + B + C + D + E + F + G = 28  ( 1 to 7 sum)

= 28 + 2D

28 + 2D  is Divisible by  3 numbers

Hence

D = 1   ,  4   ,   7  

Case 1  

D = 1

28 + 2D = 30    Sum of Each   = 10   ,  D = 1

=> A + G = B + F = C + E  = 9

2 + 7 = 3 + 6  = 4 + 5

Sum is not equal to 12. So this case is invalid

Case 2  

D = 4

28 + 2D = 36    Sum of Each   = 12   ,  D = 4

=> A + G = B + F = C + E  = 98

only possible solution

1+ 7 = 2 + 6  = 3 + 5

Case 3

D = 7

28 + 2D = 42    Sum of Each   = 14   ,  D = 7

=> A + G = B + F = C + E  = 97

1 + 6 = 2 + 5  = 3 + 4

Sum is not equal to 12, so case is invalid

Hence the solution will have 4 in the center.

Step-by-step explanation:1+2-3+4=1

Answer:

∠ 2 = 60°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 remote interior angles.

123° is an exterior angle of the triangle , then

∠ 2 + 63° = 123° ( subtract 63° from both sides )

∠ 2 = 60°

Answer:

60

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180° so we can write the following equation to find the value of missing angle:

∠2 + 63 + 57 = 180 add like terms

∠2 + 120 = 180 subtract 120 from both sides

∠2 = 60

The pedestrian route that runs diagonally across the park is 5√10 miles.

It states that in a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.

We have,

A rectangle:

Length = 15 miles

Wide = 5 miles

Diagonal length can be considered as the hypotenuse.

Applying the Pythagorean theorem.

Diagonal side² = length² + wide²

Diagonal side² = 15² + 5²

Diagonal side² = 225 + 25 = 250

Diagonal side = √250 = 5√10 miles.

The simple interest rate will be 19.2% per year.

We need to find the simple interest which is I = P * R * T

where,

I is the interest,

P is the principal,

R is the interest rate and

T is the time period.

Here, I = the amount you payed - the amount that you owed

= $1800 - $1300 = $500

Now, I = 500

T = 2 years

P = 1300

According to the formula,

500 = 1300 * R * 2

⇒ 500 = 2600* R

∴R = 500/2600 = 0.1923

Multiplying it by 100, we get 19.23%.

Rounding off 1 decimal place, we get 19.2%.

By taking a quotient between the total area and the number of children, we conclude that each one will get 9 ⁴/₅ acres.

Here we know that a farmer has a total of 49 acres, and he wants to divide it evenly among his 5 children.

So we just need to take the quotient between 49 and 5, this is:

49/5

First, we can rewrite:

49 = 45 + 4

Replacing that in the quotient we get:

49/5 = (45 + 4)/5 = 45/5 + 4/5

The first term is equal to 9, then we can rewrite:

49/5 = (45 + 4)/5 = 45/5 + 4/5 = 9 + 4/5

From this quotient, we conclude that each one of the 5 children gets an area of 9 + 4/5 acres. Written as a mixed number this would be:

A = 9 ⁴/₅ acres.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed over a larger range, a low standard deviation suggests that the values tend to be near to the mean (also known as the anticipated value) of the collection.

The lower case Greek letter (sigma), for the population standard deviation, or the Latin symbol s, for the sample standard deviation, are most frequently used in mathematical literature and equations to indicate standard deviation. Standard deviation may be written as SD.

EXPLANATION : The speed recordings follow an approximately normal distribution the mean of

That is.

20 — 23.84 +y(3.56)

Also b is the remainder when n is divided by 13 i.e., [tex]n\equiv b\ mod 13[/tex]

Then by Division algorithm, there are integers k and m such that n = a + 10k and n = b + 13m

These two equations are equivalent to

13n = 13a +130k and 10n = 10b + 130m

Adding these two equations, 23n = 13a + 10b + 130(k + m)

⇒ [tex]23n\equiv 13a+10b\ mod\ 130[/tex]

gcd (23,130) = 1

So 23 has an inverse modulo 130.

Therefore, [tex]n\equiv 23^{-1} (13a+10b) \ mod\ 130[/tex]

Applying Euclidean algorithm for 130 and 23,

130 = 23 x 5 + 15

23 = 1 x 15 +8

15 = 1 x 8 +7

8 = 1 x 7 + 1

Therefore, 1 = 8 - 7 = 8 - (15 -8 ) = 2 x 8 - 15 = 2( 23 - 15 ) - 15

                    = 2 x 23 -3 x 15 = 2(23) -3(130-5x23) =17(23) -3(130)

So inverse of 23 = 17

So, [tex]n\equiv 17 (13a+10b) \ mod\ 130\equiv 221a +170b \ mod \ 130 \equiv \bold{91a+40b \ mod\ 130}[/tex]
