4f=2500 because 4 trips from 2500 means

.
Answer: 63.62 square m.
Step-by-step explanation:
Find the Radius so 9/2= 4.5
Area = π r²
Area 3.14(20.25)
Area equles 63.62
The answer to number 18 is - 0.25 or 1/4

(X+5)²=4/4
X+5=1, X+5=-1
X=1-5 X=-1-5
X=-4 X=-6
Answer:
769MIN
Step-by-step explanation:
Hello!
To solve this problem we must use the straight line equation, this equation is as follows
Y=mx+b
where
X= time
Y=Temperature
b=
intercept with the y axis when x = 0, therefore y = 400
m=k=
temperature decrease with respect to time=-0.325
now we replace the values in the equation of the line
Y=-0.325X+400
Now we find the time it takes for the pizza to reach 150 F replacing in the equation and finding X
150=-0.325X+400
150-400=-0.325X+
