Answer:
we conclude that the total number of perfect odd squares between 5 and 211 will be: 6
Step-by-step explanation:
Let us check by taking squares
As taking 14² = 256 would exceed 211, and 1² = 1 is smaller than 5.
Therefore, we conclude that the total number of perfect odd squares between 5 and 211 will be: 6
Answer:

Hannah has 36 rocks in total. 3 of them are silver, are blue and are purple. Then she has more purple rocks than blue.
Answer: 2.25 x 10 -7 -7 is the exponent
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer:
Try c
Step-by-step explanation:
Let's start with just regular fractions and let's ignore the negative sign for now. 3/10 x 4/5. Since 10 and 4 are multiples of 2, we can simplify it. so it will be 3/2 x 2/5 and you'll get 6/10. 2 can still get into 6 and 10, so the simplest form would be 3/5. Simply add the negative sign and your answer is -3/5
