If (5^4)m = 5^12, what is the value of m? (4 points)
A. 2
B. 3
C. 5
D. 8

Answers

Answer:

The value of m is 3

Step-by-step explanation:

(5^4)m =5^12

M = 3

(5^4)3 =5^4*3=12

(5^4)3 = 5^12

Answer:

(5 ^4)^m = (5)^12

625^m = (5)^12

Taking logs of both sides

log(625) *m = log (5) *12

m = log (5) *12 / log(625)

m =  0.69897000434 * 12 / log (625)

m = 0.69897000434 * 12 / 2.7958800173

m = 0.69897000434 * 12 / 2.7958800173

00
The amount of 20% saline solution needed is
CC.
B

Answers

We will need 85cc of 20% saline solution for the mixture

Let the amount of 20% saline solution be "a"

If a nurse mixes 40 cc of a 70% saline solution with a 20% saline solution to produce a 36% saline solution, then the finished product will be 40 + a cc which containing 36% saline solution.

The saline content will therefore be expressed as:

(70% of 40)+20% of a = 36% of (40 + a)

0.7*40 + 0.2a = 0.36(40 +a)

28 + 0.2a = 14.4+0.36a

28 - 14.4 = 0.36a - 0.2a

13.6= 0.16a

a = 13.6/0.16

a = 85

This means that we will need 85cc of 20% saline solution for the mixture

Relative Change: ? This car's value decreased by

Round your answer to the nearest tenth of a percent.

Answers

Answer:

The actual change in the car's value is $[tex]1700[/tex] and the relative change is [tex]7.20[/tex]%.

Step-by-step explanation:

It is given that the value of a car is dropped from $[tex]23600[/tex] to $[tex]21900[/tex].

So, the change in the value is the drop in the value of car, which is, [tex]23600-21900=1700[/tex].

So, the actual change in this car's value is $[tex]1700[/tex].

The relative change can be given by the expression,

[tex]\dfrac{\:\rm{Actual Change}}{\:\rm{Original Value}}\times100[/tex]

Substituting values, the relative change can be given by,

[tex]\begin{aligned}\dfrac{1700}{23600} \times 100&=\dfrac{1700}{236}\\&=7.20\end{aligned}[/tex]

Gymnast Clothing manufactures expensive hockey jerseys for sale to college bookstores in runs of up to 150. Its cost (in dollars) for a run of x hockey jerseys is
C(x) = 1500 + 10x + 0.2x2 (0 ≤ x ≤ 150)
1. Gymnast Clothing sells the jerseys at $90 each. Find the revenue function.
2. Find the profit function.
3. How many should Gymnast Clothing manufacture to make a profit?

Answers

The Revenue function for the number of jerseys x sold is ; R(x) = 90x

The profit function from the sale of x jerseys is ; P(x) = - 0.2x² + 80x - 1500

The number of Jerseys to manufacture in other to make profit = 20

The revenue made is the total amount made from the sale of the hickey jerseys :

Sales price per jersey = $90

Hence, the revenue made, R(x) = 90x

The Cost function, C(x) = C(x) = 1500 + 10x + 0.2x²

Recall :

Profit = Revenue - Cost

Hence,

P(x) = R(x) - C(x)

P(x) = 90 - (0.2x² + 10x + 1500)

P(x) = 90 - 0.2x² - 10x - 1500

P(x) = - 0.2x² + 80x - 1500

To make profit, equate P(x) to 0 ;

0.2x² - 80x + 1500 = 0

Using a quadratic calculator :

x = 380.22 or x = 19.72

Hence, to make a profit, the number of jerseys that must be sold is 20.

Answer:

  x = 42

Step-by-step explanation:

You know from your multiplication tables that ...

  42/7 = 6

  x = 42

__

If you like, you can solve this by multiplying both sides of the equation by 7.

  (x/7)(7) = 6(7)

  x = 42

Answer:  The correct answer is:  " x = 42 . "

_____________________

Step-by-step explanation:

------------------------------------------

Given:

 x/7 = 6 ;   Solve for "x" ;

_____________________

 "x" divided by "7" equals "6" ;

to solve for "x"

______________________

Multiply Each Side of the equation by "7" :

______________________

 →  "  7 * [tex](\frac{x}{7}) = 6 * (7)[/tex] ;

______________________

On the "left-hand side" of the equation; the "7's" cancel out;  

   → {since: " 7 / 7 = 1 " } ;

___________________

and on the "right-hand side" of the equestion:  

    →  6 * 7 = 42 ;

___________________

So; we have:  " x = 42 " ; which is our answer.
