1) The best thing to do here is to divide the two weights of the buses and fin out what you need to multiply it by. 100/50= 2. Therefore, you've got to multiply the amount of people by 2. 10*2= 20 Therefore, it takes 20 people to pull a 100 ton bus.
2) Here, you should work out what each one is worth. Half of 40 is 20. one fourth of 20 is 5. Therefore, half of 40 is larger.
3) The best thing to do is to divide 32 by 8, and then multiply the number of degrees by this. 32/8=4 110*4= 440 Therefore, the ball rotates 440 degrees in 32 seconds.
4) the best thing to do is to find what one part is worth- and to do this, you have to add together the amount of roses and divide this by the total roses. 4+6= 10 50/10= 5 The roses are 6 parts yellow, therefore, 6*5= 30, there are 30 yellow roses.
Only x-intercept because if you want to know about x-intercepts so y will be zero (y=0) then 0 =4x^2 -12x + 9 0=(2x-3)(2x-3) 0=2x-3 so x=3/2 that is x-intercept
