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!

A newborn baby had about 26,000,000,000 cells. An adult has about 4.94 times 10 to the 13 power cells. How many times as many ce

Tom [10]

2.6 • 10^10 = 26,000,000,000
4.94 • 10^13 = 49,400,000,000,000

49,400,000,000,000/26,000,000,000= 1900

And adult had 1900 times more cells than a newborn. Or if you want to put it in scientific notation it would be 1.9 • 10^3

Consider the enlargement of the pentagon. A small pentagon has a bottom side length of x centimeters and left side length of 7 c

LuckyWell [14K]

When the pentagon is drawn to scale then its value of x will be x=3.3 cm

<h3>What is the pentagon?</h3>

The pentagon is defined as the shape having five sides connected together.

Now it is given in the question that

For small pentagone

Bottom =x

left =7 cm

For larger pentagone

Bottom=7cm

left=15cm

Now since the pentagon is actually dilated from its size to the new bigger size. It means that the equivalent ratio of both the pentagons will be equal.

For smaller pentagon

$\rm Equivalent \ Ratio = \dfrac{Bottom}{Left} =\dfrac{x}{7}$
