D=r^2 means diameter equals radius squared
egoroff_w [7]3 years ago
3 0
The equation d=2r is used in geometry to find the diameter of a circle when its radius is know. d represents, and r represents the radius. This formula is explained by the fact that the diameter of a circle is equal to 2 times the length of its radius.
For example, if we have a circle with a radius of 4, and we need to find its diameter we can use the formula d = 2r:
d = 2r = 2*4 = 8

Hope this Helps! :)

Chain complete 40% of her homework on Monday and 2/3 on Tuesday if she started her homework on Monday what fractional part of he
kotykmax [81]

Answer:

1/5

Step-by-step explanation:

For Monday

The fraction of homework Chain completed =

40% of her homework

= 40% = 40/100

= 2/5

For Tuesday

The amount of home work left =

= 1 - 2/5

3/5

The fraction of homework Chain completed on Tuesday = 2/3

= 2/3 Of 3/5

= 2/3 × 3/5

= 2/5

Let the total complete homework be represented by 1

Hence:

The Fractional part of her homework left for her to complete after Tuesday =

1 - (2/5 + 2/5)

Lowest common denominator is 5

= 1 - (2 + 2/5)

= 1 - (4 /5)

= 1/5

kogti [31]

Answer:

Simplifying

12t + -8t = 0

Combine like terms: 12t + -8t = 4t

4t = 0

Solving

4t = 0

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Divide each side by '4'.

t = 0

Simplifying

t = 0
