Hey there!
22. 8³ means 8*8*8 not8*3. So you would have to multiply 8 three times. 8*8*8= 512. So 8³= 512
23. Like the answer above you would have to multiply 10 six times. 10^6 power is 1,000,000 and now multiply that by 8 and you would get 8,000,000
25. 8+5(4)-3(2)
Multiply and divide left to right, 5(4)= 20 and 3(2)=6
8+20-6
Add and subtract left to right, 8+20= 28
28-6= 22
29.$34
960*2=1920 (bus rentals)
80*10=800 (lunch)
1920+800=2720 (total cost)
2720/80=34 (cost per student)
39. So for 8 months
Height for 8 months = 10 + 3x8 millimeters
Height for 8 months = 10 + 24 millimeters
Height for 8 months = 34 millimeters
For 3 Years.
There are 12 months in 1 year.
For 3 years there are 12 x 3 = 36 months
Plug it into the equation
Height for 36 months = 10 + 3x36
Height for 36 months = 10 + 108
Height for 36 months = 118 millimeters
54. a . It costs $20 for an adult and $13 for a student because for every adult it costs $20 each and for every student, it costs $13 each
B. 20(4)+13(24)
80+312= 392
So The total cost is $392
Hope this helps!
