Mathematics

kaheart [24]4 years ago
6 0
This is the concept of proportionality; we are required to find the combined variation for the volume formula given by:
V=length*width*height
V=lwh
here we see that volume is directly proportional to width, length and height;
therefore the correct answer is:
A] V varies jointly as l,w and h

Al, Tom and Joe share €3000.
agasfer [191]

Answer:

Tom's share = €800

Step-by-step explanation:

Given that:

Amount shared by Al, Tom and Joe = €3000

Ratio of Al's share to Tom's share = 5 : 4

Joe's share = 1.5(Tom's share) = 1.5(4) = 6

Therefore,

Ratio of Al, Tom and Joe = 5 : 4 : 6

Let,

x be the number of times of amount each get.

5x + 4x + 6x = 3000

15x = 3000

Dividing both sides by 15

\frac{15x}{15}=\frac{3000}{15}\\x=200

Tom's share = 4x = 4(200) = €800

Hence,

Tom's share = €800

What is the future value of a R 75 000 deposit made every 6 months for 3 years using an annual rate of 10% compounded semi-annua
dolphi86 [110]

Answer:

The future value is: RS 132867.075

Step-by-step explanation:

Given

PV = 75000 --- present value

r = 10\% --- annual rate

n = 6 --- number of times compounded (3 years/ 6 months)

Required

The future value

This is calculated as:

FV =PV * (1 + r)^n

FV = 75000 * (1 + 10\%)^6

FV = 75000 * (1 + 0.10)^6

FV = 75000 * (1.10)^6

FV = 132867.075

<em>Hence, the future value is: RS 132867.075</em>
