Answer:

if the question is what is the are of the circle without the rectangle inside it, then we could solve it easily using the Mathematical formula for A Circle's area which is

$\pi {r}^{2}$

since a radius is half a diameter, and the diameter is 8cm, the radius becomes 4 cm

Step-by-step explanation:

π×4^2

3.14×16

50.24

.If you dye 1/3 of it blue, ¼ pink and 2/5 black, how much of your original hair colour is left?

sineoko [7]

Answer:

You have 1/60 of the original hair color left

Step-by-step explanation:

Add up the fractions

1/3 + 1/4 + 2/5

Get a common denominator of 60

1/3 * 20/20 + 1/4 * 15/15 + 2/5 * 12/12

20/60 + 15/60 + 24/60

59/60

The total is 1 or 60/60

60/60 - 59/60

1/60

You have 1/60 of the original hair color left

Which of the following equations does NOT represent a proportional relationship

jeka94

A proportional relationship has the form: y=mx
The first three options (y=(1/3)x, y=2x, and y=3.4x) have this form. The fourth option is:
y+1=2x
If we isolate y:
y+1-1=2x-1
y=2x-1, it does not have the form y=mx
Answer: The equation that does not represent a proportional relationship is: Fourth option: y+1=2x
