2 answers:

7 0

First you write it as a fraction as
16/28 and 240/560
240/560 can be simplified to 27/28
16/28 is not equivalent to 27/28

Hope this helps ;)

3)
Principal Amount = P = $7200
Interest rate = r = 4% = 0.04
Time = t = 8 years

Formula for compounding is:

$A=P (1+r)^{t}$

Using the values, we get:

$A=7200 (1+0.04)^{8}=9853.70$

Therefore, the compounded amount will be $9853.70

4)
Principal Amount = P = $7200
Compounded Amount = A = $9853.70

Interest Earned = Compounded Amount - Principal Amount
So,
Interest Earned = 9853.70 - 7200 = $2653.70

Therefore, $2653.70 will be earned as interest over a period of 8 years.

A cylinder and a cone have congruent bases and the same volume. What could be the height of the cylinder and the height of the c

Ahat [919]

Answer:

Step-by-step explanation:

The volume of a cylinder is expressed as

V = πr^2h

Where

π is a constant

h is the height of the cylinder

The volume of a cone is expressed as

V = 1/3πr^2h

Where

π is a constant

h is the height of the cone

If the cylinder and a cone have congruent bases and the same volume, it means that

πr^2h = 1/3πr^2h

πr^2 cancels out on both the left hand side and right hand side of the equation. It becomes

h = h/3

It means that the height of the cone is 3 times the height of the cylinder. Therefore,

If height of cylinder = 4 cm, height of cone = 12 cm

the terms in this sequence increase by the same amount each time. _19_ _ 34_ a) work out the missing terms.

vladimir2022 [97]

Answer:

The sequence is 14, 19, 24, 29, 34, 39.

Step-by-step explanation:

Let's call the common difference (the difference between two consecutive terms) as d. We see that the second term is 19 and the 5th term is 34 and since 5 - 2 = 3, we add d 3 times to 19 to get 34 so therefore:

19 + 3d = 34

3d = 15

d = 5 so the first term is 19 - 5 = 14, the third would be 19 + 5 = 24, the fourth would be 24 + 5 = 29 and the sixth would be 34 + 5 = 39.
