Answer:
we have, 1953125=5⁹, so it cannot be a perfect square. If the last digit of a given number is 5, then the last three digits must be perfect squares, 025 or 225 or 625. Otherwise, that number cannot be a perfect square. And as 125 is not a perfect square, so no number ending with 125 can be a perfect square
Answer: (4,5)
Step-by-step explanation:
Anything less than 4 and 5, would be equal to or less than 4
Answer:
A-3x3 bc the parentheses are multiplying
Assuming that a “circle graph” is a pie chart, the way of solving is this:
The degree of the angle of that pie section is relative to the entire circle just as the number of pyramids are to the number of total building blocks.
The number of pyramids out of the total is 30/150, or 1/5 (20%). This means that the angle of the section will be 1/5 the total angle measurement of the circle.
There are 360 degrees in a circle, and one fifth of this is 72 (360/5). Your answer is C.
Solution:
The expression "a(b-c)" is an example of distributive property. To simplify it, simply multiply a by the terms inside the bracket.
<u>Simplifying the distributive property.</u>
- => a(b - c)
- => (a x b) + (a x -c)
- => ab - ac
Hence, the simplified expression is ab - ac.
