90 + 25 = 115
It is: (90-25)-25 = 40
67.5
236 + 90 = 326 'More' means 'add'.
It is: (90-42)+24 = 72
171.6
Definitely COMPOSITE. Remember ALL EVEN number end in (0,2,4,6,8) are Composite, because '2' is a factor of all EVEN numbers, thereby making them Composite/Compound. NB Odd Number, ending in (1,3,5,7,9) can be either Composite or Prime, but NOT both. Since '90' end in '0' then it is EVEN. It will divide by '2' , making it composite. 90/2 = 45
You can easily figure these kind of problems out. Your first clue to your total is that you're looking for the percent of 90 that is 115. Since 115 is already greater than 90 you know your percent is going to be more than 100%, which is 90. 115 - 90 = 25 Now we have 25 remaining of 90. 25 ÷ 90 = 0.277 or 28%. 100% + 28% = 128%
20 occurs more than any other number, so it is the mode.
90 is one such number.
30
The original number is 10 because: 10 squared = 10+90
No.If an angle is acute, it is less than 90 degrees.Its complement is the number of degrees needed to total 90.Its supplement is the number if degrees needed to total 180, which is 90 more than its complement.
