Answer:
45
Step-by-step explanation:
9x10/2=45
You would do 20-6 which = 14. + 1 =15. times 8= 120 then divide that by 1/2 = 240 if you do 120 divided by .5 in a calculator thats what you get. i hope that helps you

bear in mind that, though the square has two valid roots, one negative and one positive, the hypotenuse is just a radius distance, and therefore is never negative.
If 4/10 of the population have blood type O+, that means 40% of the population have that blood type. To change a fraction to percent, the easiest way is to make the denominator 100. To do this, multiply the whole fraction by 1 (1/1, 2/2, etc). In this case, multiply by 10/10. 4/10 * 10/10 is equal to 40/100. Then, if you have a denominator of 100, the numerator is the percent. Therefore, 40/100 is 40%.
Answer:
The result is 60
Step-by-step explanation:
We have to use this expression showing BODMAS rule. According to the rule, we must first solve the brackets. In our expression, the term within the bracket is (12-4) squared = (8) squared = 64.
Then we need to perform the addition followed by subtraction.
The expression becomes:
11 squared - 64 + 3
= 121 - 64 + 3
= 124 - 64
= 60
So, the result of the expression is 60.
