The equation which represents the height of the books is  s(b)=\frac{5}{4} b

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. An equation between two sums of monomials of degree 0 or 1 is known as a linear equation.

The books are stacked one above the other and each book is 1\frac{1}{4} inches thick.

So to calculate the total height of the stack we have to multiply the number of books in the stack with the thickness of each book.

The total thickness is represented in the from of a function as

s(b) and the thickness of each book is 1\frac{1}{4}=\frac{5}{4} inches

total height=\frac{5}{4}\times b

Therefore the required equation is  s(b)=\frac{5}{4} b.

Anettt [7]

The sum of the numbers 8 × 10⁶ and 7.92 × 10⁹ in the form of scientific notation will be 7.928 × 10⁹.

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The expression is given below.

8 × 10⁶ and 7.92 × 10⁹

The addition of both terms 8 × 10⁶ and 7.92 × 10⁹ will be

⇒ 8 × 10⁶ + 7.92 × 10⁹

⇒ 8 × 10⁶ + 7920 × 10⁶

⇒ 7928 × 10⁶

⇒ 7.928 × 10⁹

The sum of the numbers 8 × 10⁶ and 7.92 × 10⁹ in the form of scientific notation will be 7.928 × 10⁹.

the length of a rectangular yard is 4 feet more than the width. the perimeter of the yard is 208 feet. write the equation that r
ad-work [718]

Answer:

Length = 54 ft.

Width = 50 ft.

Step-by-step explanation:

Let the width of the rectangle be 'w'.

According to question ,

Length = w + 4

Perimeter = 208 ft.

We know that perimeter = 2(l + w) where l = length & w = width

So,

2(w + 4 + w) = 208

=  > 2(2w + 4) = 208

=  > 2w + 4 =  \frac{208}{2} = 104

=  > 2w = 104 - 4 = 100

=  > w =  \frac{100}{2}  = 50

Width = 50 ft.

=> Length = 50 + 4 = 54 ft.

The pattern grows by 2, because if you count each cube you can see.

There will be 1 cube in Figure 0, because if it grows by 2 then you take away 2 cubes.

Help please are fractions help!!!!! thanks
Brrunno [24]

Answer:

See below

Step-by-step explanation:

To solve a proportion ( an equation with two equal fractions), cross multiply by  multiplying numerator and denominator of each fraction.

8/5=24/h                               8h = 5*24                    8h = 120              h=15

h/8=24/5                               5h = 8*24                    5h = 120              h= 24

h/5=24/8                               8h =5*24                     8h = 120              h=15

8/5=h/24                               5h = 8*24                    5h = 120              h=24

8/24=5/h                               8h = 24*5                    8h = 120              h = 15

5/8=h/24                               8h = 5*24                    8h =120               h = 15

h/5=8/24                             24h =5*8                      24h = 40             h = 5/3
