Answer:

Step-by-step explanation:

\frac{2^{6}*5^{4}*3^{12}}{2^{2}*5^{2}*3^{4}}=2^{6-2}*5^{4-2}*3^{12-4}\\\\\\=2^{4}*5^{2}*3^{8}

\frac{a^{m}}{a^{n}}=a^{m-n}, m>n

In exponent division, if both numbers have same base, subtract the exponents.

What is the number? I did many ways but i didn't found it, please guys help me with it. ​
Advocard [28]

Answer:

A). 15

B). -1.2

Step-by-step explanation:

A). [10(x+3)]-20 = 160

10x+30-20 = 160

10x+10 = 160

10x = 160-10

10x = 150

x = 150/10

x = 15

B). 5{[4(8+(5x))]-9} = 85

5(32+20x+9) = 85

5(32+9+20x) = 85

5(41+20x) = 85

205+100x = 85

100x = 85-205

100x = -120

100x/100 = -120/100

x = -1.2

Calcular la edades actuales de una madre y sus dos hijos sabiendo que hace 14 años la dad de la madre era 5
rodikova [14]

The present age of mother and her daughter respectively are; 40 and 10 years respectively.

<h3>How to Solve Algebra Word Problems?</h3>

Let x and y be the present age of mother and her daughter respectively.

Therefore;

x + y = 50

x = 50 − y     .....(1)

After 20 years, mother's age will be twice her daughter's age at the time. Thus;

x + 20 = 2(y + 20)

x − 2y = 20     .....(2)

Plugging eq 1 into eq 2 gives us;

50 − y − 2y = 20

3y = 30

y = 10

Thus;

x = 50 − 10

x = 40

Thus, the present age of mother and her daughter is 40 and 10 years respectively.

Translation of the question into English is;

The sum of the present ages of mother and her daughter is 50 years. After 20 years, mother's age will be twice her daughter's age at the time. Find their present ages.

A student earned grades of Upper AA​, Upper DD​, Upper AA​, Upper CC​, and Upper BB. Those courses had the corresponding numbers
dmitriy555 [2]

Answer:

  • The grade point average is 2.92
  • The student didn't make the​ Dean's list because the​ student's GPA is less than 3.0

Step-by-step explanation:

  • I take the grades as A,D,A,C,B not AA​,DD​,AA​,CC​,BB.
  • I take numbers of credit hours as 4,2,2,3,1 not as 44​, 22​, 22​, 33​, and 11.

Since quality points to letter grades are A=​4; B=​3; C=​2; D=​1; F=0, weighted mean is the sum of the qulity points times corresponding credit hours divided by the total credit hours:

\frac{(4*4) + (1*2) + (4*2) + (2*3) + (3*1)}{12} ≈ 2.92

Since 2.92<3.0, the student is not in Dean's list.
