Area is length x width, and perimeter is adding up all the sides together
so if it’s 32 for the perimeter, then the dimensions should be 12 and 4
12x4 is 48
12+12+4+4 is 32
Answer:
67
Step-by-step explanation:
With the information of f(2) = 22-5, you can assume the equation will be f(x) = 11x-5. Using this, you can calculate f(5) by doing 11(5)-5, which is 50. 22-5 is 17, so 50+17=67
Answer:
102.3
Step-by-step explanation:
a_38 = -5
difference d= -2.9
We use general formula
![a_n = a_1 + (n-1)d](https://tex.z-dn.net/?f=a_n%20%3D%20a_1%20%2B%20%28n-1%29d)
WE make the formula for a_38 th term
Plug in 38 for n
![a_{38} = a_1 + (38-1)d](https://tex.z-dn.net/?f=a_%7B38%7D%20%3D%20a_1%20%2B%20%2838-1%29d)
Now plug in -2.9 for d and -5 for a_38
![-5 = a_1 + (38-1)(-2.9)](https://tex.z-dn.net/?f=-5%20%3D%20a_1%20%2B%20%2838-1%29%28-2.9%29)
![-5 = a_1 - 107.3](https://tex.z-dn.net/?f=-5%20%3D%20a_1%20-%20107.3)
Now add 107.3 on both sides
102.3 = a_1
option A is correct
The denominator is 40
10-3=7 (number of students in the band who do not ride the bus)
7/40=0.175
0.174*100=17.5% chance
Hope this helps!
