You use the order of exponents my son is doing this homework the same kind of homework as you are the order for the Spells please excuse my dear Aunt Sally which means parentheses exponents and roots multiplication division addition and subtraction that's the order than what you do it in. so with this one you're going to start with the brackets
Answer: h = 12mm
Step-by-step explanation:
The volume of a pyramid is given as :
V = 
lwh
Therefore:
324 = lwh
324 x 3 = 9 x 9 x h
Therefore:
h = 972/81
h = 12mm
Answer:
B. The experimental probability of a 1 is 25%.
Step-by-step explanation:
Since there are 4 sections of equal size, the theoretical probability of landing on any one of the them is equal. The probability of landing on any one of the sections is 25%. The experimental probability is based on the results of an actual experiment, meaning spinning the spinner, and recording the results.
A. The theoretical probability of a 1 is 25%. True as explained above.
B. The experimental probability of a 1 is 25%. False. There were three spins. One spin resulted in a 1. The experimental probability of spinning a 1 is 1/3 or 33 1/3 %.
C. If you spin the same spinner again and get different results, the experimental probabilities are different, but the theoretical probabilities have not changed. True. See explanation above. The theoretical probability is always 25% for any of the sections, 1, 2, 3, or 4. The experimental probability depends on the results of the actual spins that were performed.
D. The experimental probability of a 2 is 0%. True. The spinner was spun 3 times. There was no result of a 2, so the experimental probability of landing on a 2 is 0%.
Answer: The false statement is B. The experimental probability of a 1 is 25%.
Answer: 2.5%
Step-by-step explanation:
Let's use the rule of 3 here.
If the total price is $275,000 or 100% of the sale, then $6,875 is X% of the total sale.
Let's put money on one side and percentages on the other.
Solve for x;
