3a: 15 is half of 30, so knowing that means the answer is 50%

3c. 6 over 10 as a decimal is 0.6. Which as a percent is 60%

4. Noah's method does work because 20% x 5 is equal to 100% of a number.

A piano has 52 white keys. Write and use an equation to find the number of octaves on a piano keyboard.
Firdavs [7]
There are 7 keys in each octave (C,D,E,F,G,A and B) so it would make sense to divide 52 to 7.
52/7=7 octaves and 3 extra kets

If the perimeter is always 36 cm, how could you draw the rectangle so that it has the maximum area?
Romashka-Z-Leto [24]

Answer:

Draw it with 9 cm for length and width.

Step-by-step explanation:

The product is the maximum area when the length and width are as close as possible, or equal to each other. Because length and width are 2 sides each, we can divide 36 by 4, which is 9.

9x9 = 81 cm^2. This is the largest area possible.
