A man bought some story books for 5 Ghana Cedis each from a bookshop
15 of the books got missing. He then sold the rest at 8 Ghana cedis each and made a profit of 90 Ghana cedis. How many books did he buy?

Answers

Answer:

Step-by-step explanation:

Let the no of books bought be x

The cost price of 1 book is 5x

No of the missing book is 15

The remaining book is x-15

The selling price of 1 book is 87

Selling price of (x-15) book is 87

Hence the number of books can be calculated as follows

8(x-15)-5x= 90

8x-120-5x= 90

8x-5x= 90+120

3x= 210

x= 210/3

= 70

Hence the number of books bought is 70

A pack of 5 of board games costs $75.
If there is a direct proportion between the price (y) and number of board games (2), which equation represents the
situation?
y = 75.2
By = 52
C y = 2
Dy = 152

Answers

Answer:

one board game cost 15 dollars

75/5=15

15y

y = number of board games and 15= the price of each board game

so to calculate any number of board games bought just input the number of board games bought for y in the expression 15y and you will get the price.

Answers

One equalion for finding the volume of a cylinder is V=Bh, where B represents the area of the base of the cylinder and h represents the height of the cylinder. Which expression could be used to find the volume of the cylinder in cubic meters ?

Answers

Answer:

we have

diameter {d}=6.8m

radius (r)=3.4m

height]h}=8.5

now

volume of cylinder=πr²h=π([6.8]/2)²×8.5=

π(3.4)²(8.5) is your answer

Step-by-step explanation:

Diameter of the cylinder=6.8m

Radius=Diameter/2=6.8/2=3.4

We know that

[tex]\boxed{\sf Volume=\pi r^2h}[/tex]

[tex]\\ \tt \mapsto \:Volume_{(Cylinder)}=\pi(3.4)^2\times 8.5 units^3[/tex]
