Answer:

b.  h = 2A/b.

Step-by-step explanation:

A = 1/2 bh

Multiply through by 2:

2A = bh

Divide both sides by b:

h = 2A/b.

Answer:  Alternate interior angles

Step-by-step explanation:

Next three terms after 27 are 36, 45 and 54.

The total distance of the putts in yards, feets and inches be 8 yd 0 ft 6 inches or 8 yd 0.5 ft 0 inches

The conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors.

As,

1 yard = 3 foot,

1 feet = 12 inches.

Now the lengths are given 15ft 4 in and 9 ft 2 in.

So, the total distance of the putts be,

=15 ft 4 in + 9 ft 2 in

=  24 ft 6 inches

= 8 yd 0 ft 6 inches or 8 yd 0.5 ft 0 inches

Answer: Mean is 12

Step-by-step explanation: Mean is adding it all up and then dividing, 12 + 13 + 11 + 11 + 13 is 60

Divide 60 by the amount of numbers, 5

60 divided by 5 is 12

1. Solve Absolute Value.

|n| > 2.5

We know either n > 2.5 or n < -2.5

n > 2.5 (Possibility 1)

n < -2.5 (Possibility 2)

Your answer is n > 2.5 or n < -2.5

Step-by-step explanation:

"properly" is very vague.

as your can imagine, particularly in math, where many things are commutative or have other degrees of freedom what do when in what sequence, you will find particularly for the little techniques many different approaches. and most of them are correct.

particularly today I keep scratching my head about what i think is immensely complicated but teachers swear they are helping the students.

anyway, this is how I do divisions by using an example :

73496 ÷ 17

the "window" I use to look at the first number is a long as the second number. in this case 2 digits.

step 1a :

as mentioned, we look at the 2 left most digits (73) and see how often 17 fits inside that as a whole :

73 ÷ 17 = 4

4×17 = 68, so we have a remainder of 73-68 = 5.

I write it like this :

73|496 ÷ 17 = 4

05 (4×7 = 28 and 5 is then 33, carry over 3,

4×1 = 4 plus carry 3 = 7, 0 difference)

step 1b :

pull the next position down

734|96 ÷ 17 = 4

054

step 2a :

we look at the bottom number and divide this by 17.

54 ÷ 17 = 3 and a remainder of 3.

734|96 ÷ 17 = 43

054

03 (3×7 = 21 and 3 is then 24, carry over 2,

3×1 = 3 plus carry 2 = 5, 0 difference)

step 2b :

pull the next position down

7349|6 ÷ 17 = 43

054

039

step 3a :

we look at the bottom number and divide this by 17.

39 ÷ 17 = 2 and a remainder of 5.

734|96 ÷ 17 = 432

054

039

05 (2×7 = 14 and 5 is then 19, carry over 1,

2×1 = 2 plus carry 1 = 3, 0 difference)

step 3b :

pull the next position down

73496| ÷ 17 = 432

054

039

056

step 4a :

we look at the bottom number and divide this by 17.

56 ÷ 17 = 3 and a remainder of 5.

73496| ÷ 17 = 4323

054

039

056

05 (3×7 = 21 and 5 is then 26, carry over 2,

3×1 = 3 plus carry 2 = 5, 0 difference)

step 4b :

pull the next position down. but we have reached the last position before the decimal point. from that moment on we create result numbers after the decimal point.

and because the left number did not have any explicit digits after the decimal point, all the numbers we are pulling down now are 0.

73496.0| ÷ 17 = 4323.

054

039

056

050

step 5a :

we look at the bottom number and divide this by 17.

50 ÷ 17 = 2 and a remainder of 16.

73496.0| ÷ 17 = 4323.2

054

039

056

050

16 (2×7 = 14 and 6 is then 20, carry over 2,

2×1 = 2 plus carry 2 = 4, 1 difference)

step 5b :

pull the next position down. because the left number did not have any explicit digits after the decimal point, all the numbers we are pulling down now are 0.

73496.00| ÷ 17 = 4323.2

054

039

056

160

step 6a :

we look at the bottom number and divide this by 17.

160 ÷ 17 = 9 and a remainder of 7.

73496.00| ÷ 17 = 4323.29

160

07 (2×7 = 14 and 6 is then 20, carry over 2,

2×1 = 2 plus carry 2 = 4, 1 difference)

step 6b :

pull the next position down. because the left number did not have any explicit digits after the decimal point, all the numbers we are pulling down now are 0.

73496.000| ÷ 17 = 4323.29

054

039

056

050

160

070

step 7a :

we look at the bottom number and divide this by 17.

70 ÷ 17 = 4 and a remainder of 2.

73496.00| ÷ 17 = 4323.294

054

160

070

02 (4×7 = 28 and 2 is then 30, carry over 3,

4×1 = 4 plus carry 3 = 7, 0 difference)

step 7b :

pull the next position down. because the left number did not have any explicit digits after the decimal point, all the numbers we are pulling down now are 0.

73496.0000| ÷ 17 = 4323.294

Correlation is a statistical measure used to measure the relationship that exists between two variables. Negative correlation is when two variables move in different direction. If one variable increases, the other variable decreases. When two variables have a negative correlation, there is a negative sign in front of the number.

The data set which contains an outlier from the given answer choices is; Choice D; {16, 42, 45, 45, 46, 48}.

An outlier in a set of data values is a data value which differs significantly from other data points and hence, tends to affect the mean of such set of data values significantly.

PLEASE HELP 80 PTS.

Step-by-step explanation:

Let's take this fun problem step-by-step:

Let's first analyze the triangle:  ΔBRE

  ∠B + ∠E + ∠R = 180

  45 + 35 + ∠R = 180

    ∠R = 100   ⇒ ∠BRE = 100 degrees

Now let's analyze ΔAQD

 ∠A + ∠Q + ∠D = 180

 30 + ∠Q + 50 = 180

    ∠Q = 100 degrees ⇒ ∠AQD = 180 degrees

Now let's consider another fact:

           ⇒ meaning that ∠AQD + ∠RQC = 180 degrees

              ⇒ ∠RQC = 180 degrees - ∠AQD = 180 - 100 = 80 degrees

            ⇒ meaning that ∠BRE + ∠BRC = 180 degrees

                ⇔ ∠BRC = 180 degrees - ∠BRE = 180 - 100 = 80 degrees

Now let's consider ΔQRC:

  ∠BRC + ∠RQC + ∠QCR = 180 degrees

   80 + 80 + x = 180

         x = 20 degrees

Answer: 20 degrees

To Find:

Area of the shaded region

Solution:

Area of shaded region:

[tex] \rm= Area \: of \: trapezium \: ABCD - Area \: of \: Trapezium \: EHGF[/tex]

We know that,

[tex] \rm \: Trapezium = 1/2 × (a+b)×h \: \: \: sq. units [/tex]

So,

[tex] \rm = 1/2 × (a+b)×h \: \: \: - 1/2 × (a+b)×h [/tex]

Trapezium ABCD:

According to the formula,

Trapezium EHGF:

Substitute:

[tex] \tt= \cfrac{1}{2} (40 + 24) \times 25 - \cfrac{1}{2} (30 + 16) \times \: 20[/tex]

[tex]\tt= \cfrac{1}{2} (64) \times 25 - \cfrac{1}{2} (46) \times \: 20[/tex]

[tex]\tt = \cfrac{1}{2} \times 1600 - \cfrac{1}{2} \times 920[/tex]

[tex] \tt \: = 800 - 460[/tex]

[tex] \rm = 340 \: cm {}^{2} \: or \: sq. \: cm[/tex]

Thus, the area of the shaded region will be 340 cm^2 .

Answer:

Step-by-step explanation:

42=--24+8k+6k-18

42=-24+14k-18

42=-42+14k

14k=-42-42

-14k=-84

k=84/14

K=6.

Hey there!

42 = -8(3 - k) + 6(k - 3)

-8(3 - k) + 6(k - 3) = 42

-8(3 - 1k) + 6(1k - 3) = 42

-8(3) - 8(-1k) + 6(1k) + 6(-3) = 42

-24 + 8k + 6k - 18 = 42

COMBINE the LIKE TERMS

(8k + 6k) + (-24 - 18) = 42

8k + 6k - 24 - 18 = 42

14k - 42 = 42

ADD 42 to BOTH SIDES

14k - 42 + 42 = 42 + 42

SIMPLIFY IT!

14k = 42 + 42

14k = 84

DIVIDE 14 to BOTH SIDES

14k/14 = 84/14

SIMPLIFY IT!
k = 84/14

k = 6

Therefore, the answer is: k = 6

Good luck on your assignment & enjoy your day!
