26/2 = 13 (13 miles per gallon) CORRECT

2/26 = 0.076... (0.076 miles per gallon) INCORRECT

39/4 = 9.75 (9.75 miles per gallon) INCORRECT

There are 276 students.
Lynna [10]

Step-by-step explanation:

Number of males is

  • 276 - 158 = 118

Number of males not enrolled

  • 118 - 82 = 36

Number of females not enrolled

  • 158 - 102 = 56

(a)

The table based on data is

<u>                 Enrolled        Not enrolled      Total  </u>

<u>Male            82                  36                     118    </u>

<u>Female        102                56                     158   </u>

Total            184                 92                     276

(b)

Percentage of students were males that went to magic college

  • enrolled male / total students =           (use table above)
  • 82/276*100% = 29.71% (rounded)

(c)

Percentage of females went to magic college

  • enrolled female / total female =           (use table above)
  • 102/158*100% = 64.56% (rounded)

B = 3m + 2p<br> Work out the value of p when B= 2 and m = 5
GarryVolchara [31]

This is called a "substitution problem" is where you have variable that have defined values and plug them in value calculate the expression.

B = 3m + 2p # Starting equation

2 = (3)(5) + 2p # Substitution

2 = 15 + 2p # Multiplication

-13 = 2p # Subtract 15 from both sides

\frac{-13}{2} = p # Divide both sides from 2

p = \frac{-13}{2} # Use the reflexive property of equality

Hope this helps!

Which expressions are completely factored? Select each correct answer. 30a6−24a2=3a2(10a4−8) 16a5−20a3=4a3(4a2−5) 12a3+8a=4(3a3+
irinina [24]

When factoring an expression, we need to identify the Greatest Common Factor of the expression (GCF). By definition, GCF is the product of prime factors involved with its Lowest Exponent.

We need to divide each term by the GCF to get the expression inside the parenthesis.

30a^6-24a^2\\ GCF\; is \; 6a^2\\ \\ 30a^6-24a^2=6a^2(\frac{3a^6}{6a^2} -\frac{24a^2}{6a^2} )=6a^2(5a^4-4)\\ ---------------------\\ \\ 16a^5-20a^3\\ GCF \; is \; 4a^3\\ \\ 16a^5-20a^3=4a^3(\frac{16a^5}{4a^3} -\frac{20a^3}{4a^3})=4a^3(4a^2-5) \\ ---------------------\\ \\ 12a^3+8a\\ GCF \; is \; 4a\\ \\ 12a^3+8a=4a(\frac{12a^3}{4a}+\frac{8a}{4a})=4a(3a^2+2)\\   ---------------------\\ 24a^4+18\\GCF \; is \; 6\\\\24a^4+18=6(\frac{24a^4}{6} +\frac{18}{6})=6(4a^4+3) \\    ---------------------

Conclusion:

From above we can conclude that the below expressions are factored completely

16a^5-20a^3=4a^3(4a^2-5)\\ \\ 24a^4+18=6(4a^4+3)
