Answer:
$4 for each person
Step-by-step explanation:
First we have to calculate how much money has money other than for food
for this we multiply the number of guests by the value of each dinner
$8 * 10 = $80
Now that we have the total value of the dinner we substract from the total money
$120 - $80 = $40
This is the mount that she can spend on party favors
Then we split the $40 with the total number of guests to know how much we can spend for each person
$40/10 = $4

Answer:
145
step by step explanation:
perimeter definition:
perimeter definition:the continuous line forming the boundary of a closed geometrical figure.
add up the length of the sides:
80+20+45=145
Answer:
The time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.
Step-by-step explanation:
Total number of oscillations = 24
Time taken to complete 24 oscillations = 2 seconds
So, the frequency 'f' of the simple pendulum will be:


Let 'T' be the time period.





Therefore, the time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.
That would be-
f(t)=80t+4
How I worked that out-
f(x)=mx+b
b= the y intercept which is 4
mx= your slope, which is 80t
f(t) is your height
