Mathematics

4 0

Answer:


Step-by-step explanation:

A. 0.36 g/cm³

Explanation:

Density = mass/volume

We know the mass, but we must calculate the volume.

The formula for the <em>volume of a sphere</em> is

V = ⁴/₃πr³

r = 2 cm

V = ⁴/₃π × 2³

V = (4π×8)/3

V = (32π)/3

V = 33.5 cm³

=====

Calculate the <em>density </em>

Density = 12/33.5

Density = 0.36 g/cm³

The density of the sphere is 0.36 g/cm³.

The washing machine had a selling price of P4,792. It had been marked up by P1,248. What was the cost? What was the mark-up rate
LUCKY_DIMON [66]

Answer:

The cost of the washing machine is P 3,544

The mark-up rate is 35.21%

Step-by-step explanation:

1. We want to calculate the cost

Mathematically, this is the difference between the selling price and the mark up

We have this as;

4,792 - 1,248 = P 3,544

2. Here, we want to calculate the mark-up rate

Mathematically, this is the percentage of mark-up

That is;

mark-up/cost price * 100%

: 1,248/3,544 * 100% = 35.21%

Yakvenalex [24]

firstly, we have to find the difference

the diff is 6

we apply the concept diN+0

Di is difference

N is n

0 is first term - difference

first term is 3

diff is 6

3-6 = -3

nth term is 6n-3

then, we just substitute which is n is the 36th term

: 6(36)-3 = 213
