h(x) = x+8
Write g(h(x)) as an expression in terms of x.
g(h(x)) =

Answer: x=17

Step-by-step explanation:

1.Identify relationship

Since both the angles are on the inside of both parallel lines and on the same side of the transversal you know that you have a same side interior relationship that makes them supplementary

2. set up equation

because they are supplementary you know that they are equal to 180 which gives the equation: 3x+6+123=180

3. solve the equation

3x+6+123=180

3x+129=180 | combine like terms

3x=51 | subtract 123 from both sides

x=17 | divide by 3 on both sides

By using the method of subtraction, the profit earned by charles is £4.8

To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.

Given that,

There are 15 pens in each pack.

Each pack costs £4.20.

Charles sells each pen for 60p but he only manages to sell of the pens.

60p x 15 = 9

So, the profit earned by charles is 9- 4.20 = 4.8

Therefore, the profit earned by charles is £4.8

The ships and the port form a right triangle and hence, their distance is 72.1 nautical miles

Knot is a velocity unit equals to nautical miles per hour.

The situation can be depicted in the attached picture.

The distance travelled by the 1st ship after 2.5 hours is:

s1 = 16 knots x 2.5 hours = 40 nautical miles.

The distance travelled by the 2nd ship id:

s2 = 24 knots x 2.5 hours = 60 nautical miles.

Since the angle difference between those 2 ships is 90⁰, the distance between the ships can be obtained using the Pythagorean Theorem.

Referring to the attached picture,

d² = 40² + 60²

d² = 1600 + 3600

d² = 40² + 60²

The number of tapes cut is 3 pieces.

He has a roll of tape that is 4 1/2 yard long.

He cuts the tape into pieces that are each 3/2 yard long.

Therefore, the number of roll of tape cut can be calculated as follows:

Initial length of the tape in yard = 4 1 / 2 = 9 / 2 yards

Length of the tape cut in yard = 3  /2 yards

Hence,

number of tape cut = 9 / 2 ÷ 3 / 2

John is putting 10 books in a row on his bookshelf. he would arrange it in

40,320 ways.

Generally, A permutation is a rearrangement of a set of elements. In other words, it is a way to arrange a set of items in a specific order. For example, the permutations of the set {1, 2, 3} are {1, 2, 3}, {1, 3, 2}, {2, 1, 3}, {2, 3, 1}, {3, 1, 2}, and {3, 2, 1}. The number of possible permutations of a set of n elements is n!.

John is placing 8 books on the shelf in between Pride and Prejudice and Little Women.

The number of ways to arrange these 8 books is 8! (8 factorial).

since the order of the books in the first and last spots is predetermined,

The final answer is 8! = 40320ways

= 40,320 ways.

The numerical value of side RS of the rectangle with a perimeter of 144 units is 30 units.

A rectangle is simply a 2-dimensional shape with parallel opposite sides equal to each other and four angles are right angles.

The perimeter of a rectangle is expressed as;

P = 2( l + w )

Given the data in the question;

First we determine the value of the variable z, plug the given values into the perimeter formula and solve for z.

P = 2( l + w )

144 = 2( (4z + 2 ) + (3z) )

144 = 2( 4z + 2+ 3z )

144 = 2( 7z + 2 )

144 = 14z + 4

14z = 144 - 4

14z = 140

z = 140/14

z = 10

Now, find the numerical value of side RS.

Width RS = 3z

RS = 3( 10 )

RS = 30

Therefore, the length of side RS of the rectangle is 30 units.
