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.

Q4, 4y²=60
y=√15 ( i am not sure)
q6, (5+y) ²=81
5+y=9
y=4
q7 (x+4) (x) =77
x²+4x-77=0
(x+11) (x-7) =0
x=-11(rej) or x=7
therefore ,length= 7+4=11cm
breadth=7cm

A right cylindrical container perfectly holds 5 tennis balls placed one above the other. The radius of each ball is 3.35 centime
mash [69]

Answer: 394 cm3


Step-by-step explanation:

volume of cylinder - volume of 5 balls=extra volume

voc=πr2h=1181.09

pi=22/7

r=3.35

h= 5 x diameter of ball=33.5 (diameter = 2r)


vo5b=5(4/3πr3)=787.4

r=3.35

ev=voc-vo5b

=393.69


ROUND TO 394

A 4 cm x 6 cm rectangle sits inside a circle with radius with 11 cm. What is the area of the shaded region?
Novosadov [1.4K]

Answer:

The area of the shaded region is (121\pi -24)\ cm^{2}

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the circle minus the area of the rectangle

so

A=\pi r^{2} -bh

we have

r=11\ cm

b=4\ cm

h=6\ cm

substitute the values

A=\pi (11^{2}) -(4)(6)

A=(121\pi -24)\ cm^{2} ----> exact value of the shaded area
