Answer:
Step-by-step explanation:
Time taken to eat the pizza in seconds =28×60=1680 seconds
If it takes 20seconds to lift, bite and chew,
Then the total bites taken to finish the pizza =1680/20 =84 bites
If for each bite 9cm² disappeared, then area that disappeared for 84bites =84×9cm² = 756cm²
Total area of pizza =756cm²
If area =(πd²)/4,
Then d² =(4×A)/π
d²=4×756/3.14=963.06
d=√963.06 = 31.03cm
1 centimeter=0.394inches
31.03cm= 0.394×31.03=12.23 inches ≈ 12inches(to the nearest inch)
The diameter of the pizza is 12inches
It’s b
Z+23=41
Because you don’t know what z is
Y=4x+7
So 4 is the rate of change because if you solve for y, x is the rate of change
Answer:
You divide by - 1
Step-by-step explanation:
-x divided by - 1 is x
5 divided by - 1 is - 5
x > - 5
