Each number after the decimal goes in this order:
tenth
hundredth
thousandth
1. Looks like it's under the second number after the decimal. This would be the hundredth. The number after it is less than 5 so you would round down and keep the number 7, which makes 0.67
2. Being under the first number after the decimal, it would be the tenth. The number 8 is higher than 5 so you need to round the 2 up to three, making it 4.3
Do you think you could solve the rest or would you like more examples?
You would use 12 boxes of rice. This answer can be found since 13 goes into 39 3 times, so one would have to triple the recipe in order to make enough for 39 people. If they are tripling the recipe they are going to need triple the rice, so 4x3 is 12, 12 boxes of rice.
33%of360=118.8
equation: 33% of 360= 360*33%=118.8
For x=2, substitute in F(x) to find y ---> 2^2-5 =-1
for x=4 , F(4) = 4^2-5 = 11
for x=7 , F(7) = 7^2-5=44
The range is {-1, 11, 44}
