Answer:6
Step-by-step explanation:
using BIDMAS: Brackets,Indices,division,multiplication,addition,subtraction.
1) Firstly you do the problem in the brackets. (-19 - -20) two negatives next to each other make a plus(+) meaning (-19 - -20) = (-19+20) which = 1
2) Next Step is to do the multiplication section. Since we got 1 in place instead of (-19 - -20) we multiply -3 by 1 which = -3.
3) Now the equation we have is 11 + -8 - -3. In BIDMAS both addition and subtraction are equal therefore we can do it in any order. 11 + -8 is the same as 11 - 8 = 3
4) The problem we have now is 3 - -3, like we said before two negatives next to each other make an addition sign(+) so 3 - -3 = 3+3 = 6, therefore getting the answer 6.

Answer:
area = 45
Step-by-step explanation:
triangle = 7*6. / 2 = 21
rectangle 4*6=24
24+21= 45ft squared
We know that
15 1/4 acres-----------> (15*4+1)/4-----> 61/4 acres
[<span>number of lots]=(61/4)/(2/3)----> (61*3)/(4*2)---> 183/8----> 22.875
22.785-----> 22 7/8
we know that
7/8--------> multiply by 3-------> 21/24
2/3-------> multiply by 8-------> 16/24
21/24-16/24-------> 5/24
so
22 7/8 is equals to--------> 22 21/24----> 22 (16/24+5/24)
t</span><span>he maximum number of lots that can be created are 22+1-----> 23 lots
</span><span>and there is a remnant of 5/24</span>
The adjective that best describes the experiment listed in detail above would be double-blind. This is because both the mad scientist and the manufacturer are both blind to each other's experiments.<span />
