Answer:

Step-by-step explanation:

Apply the natural log to both sides we have

[tex](-(2/3)x -1 ) \ln 2 = (3-2x)\ln 3\\-x(2/3)\ln 2 + 2x\ln 3 = 3\ln 3 -\ln 2\\x\left(\frac{-2}{3}\ln 2 +2\ln 3\right)=\ln (27/2)\\x\left(\ln 9 -\ln \sqrt{8}) =\ln(27/2)\\\\x\ln (9/\sqrt{8})=\ln(27/2)\\\\x= \ln(27/2) / \ln(9/\sqrt{8})[/tex]

Answer:

d. 0.25q+0.10d

Step-by-step explanation:

Because quarters are equivalent to 0.25 and dimes are 10 cents, option d is correct.

The expression to find the total amount of money in Andrea's jar is: 0.25q + 0.10d.

Thus, option (D) is correct.

A quarter is worth $0.25, and the number of quarters is represented by q.

A dime is worth $0.10, and the number of dimes is represented by d.

To calculate the total amount of money, multiply the value of each coin by the respective quantity and sum them up.

So, the expression to find the total amounts is 0.25q + 0.10d

Here, expression accounts for the value of each coin (0.25 for a quarter and 0.10 for a dime) and multiplies it by the corresponding quantity to obtain the total amount of money in dollars.

Thus, option (D) is correct.

Answer:

10boys, 17 girls

Step-by-step explanation:

10+17=27,

17-10=7

Answer: there are 17 girls in the class

Step-by-step explanation:

let the number of boys be x

and the number of girls be re[presented as 7+x

Since there are a class of 27 containing the sum of the boys and girls, we have our equation as

boys +girls =27

x+ 7+x=27

7+2x =27

2x=27-7

2x=20

x=20/2=10

Boys =x=10

girls= 7+x=7+10=17

90,000 units of the product has to be sold each year in other to break even.

The old established price = 42 per unit :

The break even unit is the number of units sold such that the net profit = 0

(expenses - income) = 0

The expenses = (Fixed cost + variable cost)

Fixed cost = 540000

Fixed cost = 540000Variable cost per unit = 36

Let the number of units required to break even = x

Expenses = income or revenue

(540000 + 36x) = 42x

540000 + 36x = 42x

540000 = 42x - 36x

540000 = 6x

x = 540000 / 6

x = 90000

Hence, 90,000 units has to be sold at the old established price in other to break even.

Answer:

Step-by-step explanation:

The measure of angle 4 for the given parallel lines and angle is equal to 26°.

In the figure the parallel lines and the transversal forms angle 1 , angle 2 , and angle 4.

As per the diagram,

Angle 1 is vertically opposite angle to angle 2.

This implies,

Measure of angle 1 = Measure of angle 2.

Here, Measure of angle 1 =  26 degrees.

⇒ Measure of angle 2 = 26 degrees ( vertically opposite angles)

Now , Angle 2 and angle 4 are corresponding angles.

⇒measure of angle 2 = measure of angle 4

⇒ Measure of angle 4 = 26 degrees.

Therefore, the measure of angle 4 is equal to 26°.
