Answer:
0.75 = 375/100
Step-by-step explanation:
375/100 = 3.75 and there is no 3 as the whole number.
Answer:
Total area to be painted in gold = 24000 cm²
Step-by-step explanation:
Total height of the stairs = 120 cm
Total standing stairs = 4
Therefore, height or width of one standing stair as shown in the picture,
=
= 30 cm
Length of every stair has = 100 cm
Every horizontal and vertical stair has the same area.
Area of one stair = Length × Width
= 100 × 30
= 3000 cm square
There are 4 horizontal and 4 vertical similar stairs to be painted in gold.
Total area to be painted in gold = 8 × Area of one stair
= 8 × (3000)
= 24000 cm²
Total area to be painted in gold = 24000 cm²
For the answer to the question above,
It seems the function f(x) is 3/(x+4).
If the function is f(x) = 3 / (x + 4), a table could be
x f(x)
-8 -3/4
-7 -1
-6 -3/2
-5 -1
(-4 is no a valid input)
- 3 3
- 2 3/2
-1 1
0 3/4
1 3/5
2 3/6 = 1/2
3 3/7
4 3/8
If the function is f(x) = (3/x) + 4
Just substitute different values for x and obtain the respective outputs. In this case, x has to be different of o, i.e. 0 is not a valid input.
Answer:
400 cm
Step-by-step explanation:
20 cm x 20 cm = 400 cm
using factoring by grouping:
(x^3 + x^2) + (9x + 0)
x^2(x+1) + 9(x+1)
(x^2+9)(x+1)
