When rounding any number anything greater than 5 you go up and anything less than 5 you round down.
nearest ones 86120 ( 4 is lower than 5 you go down)
nearest tens 86100 ( 2 islower than 5 you go down)
nearest hundreds 86000( 1 is lower than 5 you go down)
nearest thousands 87000 ( 6 higher than 5 you go up)
nearest ten thousands 90000 ( 8 is higher than 5 you go up)
<span> tan(x)/ cos(x)-sec(x)
tanx/(cosx-1/cosx)
tanx/cos^2x-1)--------------------1-sin^2x=cos^2x
-tanx/sin^2x
-(sinx/cosx)/sin^2x
-1/sinxcosx
multiply 2/2
-2/2sinxcosx-------------sin2x=2sincosx
-2/sin2x------------------1/sinx=cosecx

To answer this question you need to first set up the small, medium, large number of cakes as a ratio with a total. From here you will create a new ratio of the correct number of small medium and large Cakes sold using the total 216. The factor would be to multiply by nine. -Step 1 in picture. After this you would read what the relationship is between a medium and a small and the large and the small profits are - Step 2 in picture. After this you would represents the total profit based on the number of small medium and large cakes that were sold. Making this equal to L648.45. To find the profit for one small, you would then divide 648.45 by the 495 you got when you simplify the expression. The answer is L1.31.
What is ocean expansion:
Eustatic change is the expansion of the ocean due to the addition of water. The extra amount of water released into the ocean body is due to melting ice sheets and glaciers. Warmer temperatures accelerates the melting, adding more water into ocean the than previous decades.
Answer:
It will be seen in every place close to the sea or beaches also many island will go under.
X=7.5 area= 42
You know that the total perimeter is 39 so to find x you need to add what you already have. You’ll find there are 3 sides you don’t know the length of and all you have to do is find the shorter one which is basically 9-7=2 then add everything together and subtract it from 39 then divide it by 2 to find the two sides left
