77% of the school want electronic newsletters, so 23% of the school want physical paper newsletters.
77% of 650 is 500.5.
23% of 650 is 149.5.
650/100 = 6.5
6.5x77 = 500.5
6.5x23 = 149.5
It's best to round that figure up to 150 as there will not be a parent who only needs half of the newsletter.
The missing exponent of 1/169=(1/13)
√36 = plus or minus 6. These results are real, rational, integer, whole and natural, and yes, there can be more than one answer; that's because we're solving a quadratic equation. Note that both 6 and -6, when squared, yield 36.
Each student will get 2 sheets of paper and 3 meters of balsa wood
Here it is given that , a postal service charges a flat rate of 11.10 and a additional rate of 3 / kg .We need to write the equation in slope intercept form . And let ,
So the total cost would be the sum of flat rate plus the cost of the total weight . Therefore,
Therefore the total cost would be,
Rearrange in slope intercept form , which is y = mx + c , as ;
