D=r^2 means diameter equals radius squared
egoroff_w [7]2 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! :)

Victoria is counting all of quarters and dimes from the family piggy bank for the month. If there are 12 times as many dimes are
saw5 [17]

Let number of quarters in family piggy bank = x

Let number of dimes in family piggy bank = y


Given that "there are 12 times as many dimes are there are quarters". so we can write equation:

y=12x...(i)


Given that " total change is worth $21.75".

We know that 1 quarter = $0.25 and 1 dime = $0.10

So other equation will be :

0.25x+0.10y=21.75...(ii)

Now we just need to solve both equations.

Plug (i) into (ii)


0.25x+0.10y=21.75

0.25x+0.10(12x)=21.75

0.25x+1.2x=21.75

1.45x=21.75

x=15


plug x=15 into (i)

y=12x=12*15=180


Hence final answer is given as:

Number of quarters in family piggy bank = 15

Number of dimes in family piggy bank = 180

How to find the percent?
andrew11 [14]
When you are doing actual math, you need to use actual numbers. Always convert the percentages to decimals!) Then, since "sixteen percent OF fourteen hundred" tells you to multiply the 0.16 and the 1400, you get: (0.16)(1400) = 224. This says that 224 is sixteen percent of 1400.
