Answer:
9
Step-by-step explanation:
first you add up all the numbers 9+7+11+8+10=45
then you divide by the amount of numbers there are so in this case 5 so you would do 45÷5=9 hope this helps
Answer: C
Step-by-step explanation:
This describes an expotential function
At t = 0, P = 70
Therefore, C = 70
P = 70 e^kt
Solve for k by plugging in (4,360)
k = 0.4094
plug in t(7 hours)
70 e^(0.4094*7)
The answer roughly equals C
Answer:
D) Multiplication should be performed before addition
I believe the numbers are 22, 13, and 44.
P=2w+2l
We know that P=90 and l=15 so we can plug in and solve for w:
90=2w+2(15)
90=2w+30
60=2w
30=w
The width is 30.
(you could draw a diagram by labelling the two shorter sides 15 and the other sides w)
Hope this helps!!
