Ahmed transports metal bars of mass 60kg in his van. The van can hold a maximum load of 1200kg.
For safety reason Ahmed assumes that the maximum load (1200kg) is correct to
2sf and that the 60kg mass of each bar is correct to 1sf.
Calculate the maximum number of bars Ahmed can safely load onto the van.

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Which of the following is the equation that says that the product of a number and ten is equal to 20 percent of that number ? a) 10n= 2.0n b) 10+n=.20n c) n+ .20n=10 d) 10n=0.20n

I'm confused on this could anyone me and show me what i need to do to solve it.
