log x - log 6 = 2 log 4

Answers

log(x) - log(6) = 2 log(4)

Condense the left side, using the property log(a) - log(b) = log(a/b) (if b ≠ 0):

log(x / 6) = 2 log(4)

Rewrite the right side, using the property n log(a) = log(aⁿ ):

log(x / 6) = log(4²)

log(x / 6) = log(16)

Cancel the logarithms (i.e. take the exponential of both sides):

exp(log(x / 6)) = exp(log(16))

x / 6 = 16

Solve for x :

x = 6 × 16

x = 96

7. 5x + 6y

8. Part A: y = 20x

8. Part B: $300

9. e > 12000 pounds

Step-by-step explanation:

Part A: x = 5t + 5

20 = 5t +5

15 = 5t

t = 3

Part B: x = 5t + 5

x = 5(7) + 5

x = 35 +5

x = 40

8. Part A:

Total = y

Lawns = x

Amount = $20

so y = 20x

8. Part B:

y = 20x

The rate of change in the table is 78 students per year

Step-by-step explanation:

Here, we want to get the rate of change of the function

Mathematically, we can get this by using the formula;

m = (y2-y1)/(x2-x1)

(x1,y1) and (x2,y2) are points we are to select from the table

Let us select the point (4,704) and (17,1718) from the table

The slope is thus;

m = (1718-704)/(17-4) = 78 students per year

Which statement is true about the following pair of rectangles?

Two rectangles are shown. To the left, a larger rectangle has a lower side labeled 60 centimeters and a left side labeled 30 centimeters. To the right, a smaller rectangle has an upper side labeled 6 centimeters and a right side labeled 3 centimeters.
A. They are not similar because Start Fraction 6 over 60 End Fraction≠ Start Fraction 30 over 3 End Fraction.
B. They are not similar because Start Fraction 30 over 3 End Fraction = Start Fraction 60 over 6 End Fraction.
C. They are not similar because Start Fraction 3 over 6 End Fraction ≠ Start Fraction 30 over 60 End Fraction.
D. They are similar because Start Fraction 3 over 6 End Fraction = Start Fraction 30 over 60 End Fraction.

Answers

Answer:

Option D

Step-by-step explanation:

the height of the first rectangle ( 30 ) over the height of the other rectangle     ( 3 )  is 30/3 and equals 10

the length of the first rectangle ( 60 ) over the length of the second rectangle  ( 6 )  is 60/6 and equals 10

the ratio of the sides of both rectangles are equivalent therefore the are similar

At janices age she is not only 5 times older than ross, but she is 28 years older than ross. How old is janice?

Answers

Answer:

35 years old

Step-by-step explanation:

Let Janice's age = j.

Let Ross's age = r.

j = 5r

j = r + 28

Set the equations equal to each other.

5r = r + 28

4r = 28

r = 7

j = 5r

j = 5(7)

j = 35

Answer: 35 years old

Answers

Answer:

1st pic:

x = 61

left angle = 125 degrees

right angle = 55 degrees

2nd pic:

n = 14

left angle = 78 degrees

right angle = 102 degrees

Step-by-step explanation:

1st pic:

use the following equation ⇒ 2x + 3 + x - 6 = 180

combine like terms ⇒ 3x - 3 = 180

add 6 on both sides ⇒ 3x - 3 + 3 = 180 + 3 ⇒ 3x = 183

divide both sides by 3 ⇒ [tex]\frac{3x}{3} = \frac{183}{3}[/tex]

x = 61

solve the angles by subtituting 61 for x

left angle = 2x + 3 ⇒ 2 x 61 + 3 ⇒ 125 degrees

right angle = x - 6 ⇒ 61 - 6 ⇒ 55 degrees

2nd pic:

use the following equation ⇒ 4n + 22 + 8n - 10 = 180

combine like terms ⇒ 12n + 12= 180

subtract 12 on both sides ⇒ 12n + 12 - 12 = 180 - 12 ⇒ 12n = 168

divide both sides by 12 ⇒ [tex]\frac{12n}{12} = \frac{168}{12}[/tex]

n = 14

you can find the angles by substituting 14 for n:

left angle = 4n + 22 ⇒ 4 x 14 + 22 =78 degrees

right angle: 8n - 10 ⇒ 8 x 14 - 10 = 102 degrees

Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125. Estimate the number of months that Zea can continue this pattern until she reaches her credit limit.

Answers

Fun fact actually really really sad fact i dont know

The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.

What is a credit card?

A credit card is a method of payment that is given to customers so they may pay a merchant for products and services depending on the debt they have accumulated.

Zea has a credit limit of $2,000 on her credit card. Each month, she charges about $200 and makes a payment of $125.

The distinction between the installment made and the charges done will be given as,

Difference = $200 - $125

Difference = $75

Partition as far as possible by this distinction to find the number of months that Zea can proceed with this example until she contacts her credit limit.

⇒ $2,000 / $75

⇒ 26.667 ≈ 27

The number of months that Zea can continue this pattern until she reaches her credit limit will be 27 months.
