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!

It's the 11th day of autumn and the first leaf has fallen! If the number of leaves on the ground is tripling with each passing d
AlekseyPX

Answer: 1,594,323

Step-by-step explanation:

No of leaves which falls daily on the first day = 1

No of days leaves falls = 14 days.

Solution:

No of leaves of day 1

= 1.

No of leaves on day 2

= 1*3

= 3

No of leaves of day 3

= 3*3

= 9

No of leaves of day 4

= 9*3

= 27

No of leaves on day 5

= 27*3

= 81

No of leaves on day 6.

= 81*3

= 243.

No of leaves of day 7

= 243*3

= 729

No of leaves on day 8

= 729 * 3

= 2187

No of leaves on day 9

= 2187 *3

= 6561

No of leaves on day 10

= 6561 * 3

= 19683

No of leaves on day 11

= 19683 * 3

= 59049

No of leaves on day 12

= 59049 *3

= 177147

No of leaves on day 13

= 531441

No of leaves on day 14

= 531441 * 3

= 1,594,323.

The number of leaves that would be on the ground on the 24th day of autumn would be 1,594,323
