Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer. 1 inch =1578x 10-5 miles

Answers

Answer: (7.129)*10^(7) inches.

Step-by-step explanation:

We know that:

1 inch = 1.578*10^(-5) miles.

If we divide both sides by 1.578*10^(-5), we get:

(1/1.578*10^(-5)) inches = 1 mile

63,371.36 inches = 1 mile

Now, we have 1,225 miles, this is equal to 1,125 times 63,371.36 inches

Then 1,225 miles writen in inches is:

1,125*(63,371.36 inches) = 71,292,780 inches.

Now, to write this in scientific notation, we need to count the number of decimals between the first one at the left, and the decimal point.

In this case we have 7 decimals.

Now, let's take the first 4 decimals, (7129) and write a decimal point after the first one:

(7.129)

Now let's multiply this by then to the power of 7 (where 7 is the number of decimals we found above).

Then the scientific notation of 71,292,780 inches. is:

(7.129)*10^(7) inches.

Jack and Jill applied for the same credit card from the same bank. The bank checked both of their FICO scores. Jack had an excellent credit rating, and

Jill had a poor credit rating


Jack was approved for a card with an APR of 12%. What was his monthly periodic rate?


Jill was approved for a card with an APR of 21%. What was her monthly periodic rate?


If each of them had an average daily balance of $700 and had to pay a finance charge, how much MORE will Jill pay than Jack?

Answers

Answer:

a. Jack's monthly periodic rate = 1%

b. Jill's monthly periodic rate = 1.75%

c. Amount paid more by Jill than Jack = $5.25

Step-by-step explanation:

a. Jack was approved for a card with an APR of 12%. What was his monthly periodic rate?

Jack's monthly periodic rate = Jack's annual percentage rate (APR) / Number of months in a year = 12% / 12 = 1%

b. Jill was approved for a card with an APR of 21%. What was her monthly periodic rate?

Jill's monthly periodic rate = Jill's APR / Number of months in a year = 21% / 12 = 1.75%

c. If each of them had an average daily balance of $700 and had to pay a finance charge, how much MORE will Jill pay than Jack?

Jack's finance charge = Jack's monthly periodic rate * Average daily balance = 1% * $700 = $7

Jill's finance charge = Jill's monthly periodic rate * Average daily balance = 1.75% * $700 = $12.25

Amount paid more by Jill than Jack = Jill's finance charge - Jack's finance charge = $12.25 - $7 = $5.25

Help please!!

Answers

Answer:

1/4 please put me the brainliest

Step-by-step explanation:

1. Slope
Slope: (Yb - Ya) / Xb - X-a
= (-2 - (-6)) / (14 - (-2)
= (-2 + 6) / (14 + 2)
= 4/16
= 1/4

2. Y-intercept
Y = mx + b
-6 = (1/4)(-2) + b
-6 = -0.5 + b
-6 + 0.5 = -0.5 + 0.5 + b
-5.5 = b
B = -5.5

Equation:
Y = 1/4x + -5.5
Y = 1/4x - 5.5

A movie theater sells popcorn and fountain drinks. Brett buys 1 popcorn bucket and 3 fountain drinks for his family, which costs him a total of $12.50. Sarah buys 3 popcorn buckets and 4 fountain drinks for her family, which costs her a total of $23.75. If p represents the number of popcorn buckets and d represents the number of drinks, then the system of equations

Answers

Answer: the systems of equations to solve the unit price  of popcorn and rinks are

1 p + 3 d= 12.50---- equation 1

3 p + 4 d=  23.75 ---- equation 2

The price of A popcorn bucket  = $4.25 and price of 1 fountain  drink = $2.75

Step-by-step explanation:

Step 1

If p represents the number of popcorn buckets

and d represents the number of drinks,

The expression that  Brett buys 1 popcorn bucket and 3 fountain drinks for his family, which costs him a total of $12.50 becomes

1 p + 3 d= $12.50

and The expression that Sarah buys 3 popcorn buckets and 4 fountain drinks for her family, which costs her a total of $23.75 becomes

3 p + 4 d=  $23.75

such that the systems of equations to solve the unit prices of popcorn and drinks are

1 p + 3 d= $12.50---- eqn 1

3 p + 4 d=  $23.75 ---- eqn 2

Step 2

1 p + 3 d= $12.50---- eqn 1

3 p + 4 d=  $23.75 ---- eqn 2

Multiplying equation 1 by( 3 )

1 p + 3 d= $12.50---- eqn 1 x 3

3p+ 9d= 37.5----- equation 3

and subtracting equation 2 from  equation 3  becomes

3p+ 9d= 37.5----- equation 3

- 3 p + 4 d=  $23.75

5d= 13.75

d= 13.75/5

d= 2.75

to find p, sinceaa d = 2.75,

1 p + 3 d= 12.50

1 p + 3  x 2.75= 12.50

p= 12.50-8.25

p=4.25

THerefore the price of popcorn = $4.25 and price of drinks = $2.75

Which ordered pair is not a solution of the equation y = 2x – 1
F (3,5)

G (9, 17)
J (6, 11)​

Answers

Answer:

H

Step-by-step explanation:

Answer: H

Explanation:

The format is (x,y) ; (4,9) Therefore, you plug in 4 for x then 9 for y. Which will give you “9=2(4)-1” and then simplify, which will give you.. “9=8-1 AKA 9=7” which is not accurate. Therefore that is NOT a solution to the equation...

STEP-BY-STEP:

y = 2x - 1

9 = 2(4) - 1

9 = 8 - 1

9 = 7

^^^^ NOT TRUE

So, therefore the answer IS H (4,9) because it’s asking what is NOT a solution.
