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!

What is the discriminant of 3x^2 - 10 = -2?
Tatiana [17]
The formula for the discriminant is b^2-4ac. The formula you wote is in the form of 
ax^2+c=0, so first, you need to bring that -2 to the left. When you do that, you get (the original equation would be ax^2+bx+c but you have no bx.)

3x^2-8

So, since there's no b, it would be
b^2-4ac
0^2-4(3)(-8
-12 x -8

Two numbers rolled can be added to get a sum. Find P(sum is even.)
azamat
When you roll two numbers you have four kinds of outcomes: EE, EO, OE, OO (where E = even, O = odd).

You get an even sum only if you sum two numbers that are both even or both odd, therefore the outcomes wanted are two: EE and OO.

Therefore:
P(sum is even) = 2 / 4 = 0.5

Hence, there is a 50% probability that, when you roll two numbers, their sum will be even.

11) the difference between the product of 4 and a<br><br> number and the square of the number
marta [7]

Answer:

= 4x-x^2\\\\

Step-by-step explanation:

Let the number be x;

The product of 4 and the number will be;

= 4 * x\\\\= 4x

The the square of the number is given as;

= x^2\\

Taking the difference of both expressions above;

= 4x-x^2\\\\

Factor out the common term:

= x(4-x)\\\\

Hence the difference between the product of 4 and a  number and the square of the number is = 4x-x^2\\\\
