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%
Area=51ft²
explanation: area of a triangle = basexheight divided by 2.
(the base is 17 since 11+6=17)
17x6=102
102/2=51
hope this helps :)
Answer:
C) 45 ft²
Step-by-step explanation:
<u>Formulae</u>
Area of a square = x² (where x is the side length)
Area of a triangle = 1/2 × base × height
The surface area of a square pyramid comprises:
- square base
- 4 congruent triangles
⇒ area of square base = 5² = 25 ft²
⇒ area of triangular face = 1/2 × 5 × 2 = 5 ft²
⇒ Total surface area = area of square base + 4 triangular areas
= 25 + 4(5)
= 25 + 20
= 45 ft²
The y-intercept will be 8
And then you work out the slope by replacing the c, y and the x in y=mx+c
The y and x will be any of the coordinates above
So it will be 0=m(8)+(8)
0=8m+8
So 8m=-8
Therefore m=-1
So the y-intercept is 8 and the slope is -1
