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
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.
A watercolor painting is 23 inches long by 11 inches wide. Ramon makes a border around the watercolor painting by making a mat that adds 1 inch to each side of the length and the width. What is the area of the mat?
Answer:
288 inches ²
Step-by-step explanation:
Water color painting
Length = 23 inches
Width = 11 inches
Mat that adds 1 inch to each side of the length and the width
Mat
Length = 23 + 1 = 24 inches
Width = 11 + 1 = 12 inches
What is the area of the mat?
Area of the mat = length × width
= 24 inches × 12 inches
= 288 inches ²

Convert 1.2 moles of NaCl (table salt) to grams.
Answer:
70. g NaCl
Step-by-step explanation:
For every one mole of a substance, there is a molar mass that coincides with the values of the periodic table. NaCl has a molar mass of 58.44g (Na+Cl). You then take this molar mass and multiple it by the number of moles asked (1.2) to find the grams present.
58.44g * 1.2mol = 70.128g
Then you would round to 2 sig figs to get 70. g of NaCl

A They are parallel because they have the same slope of −2.
B They are parallel because they have the same slope of one half.
C They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.
D They are lines that lie exactly on top of one another because they have the same slope and a different y-intercept.
Answer:
C. They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.Step-by-step explanation:
Given lines
6x + 3y = 12 ⇒ 2x + y = 4 ⇒ y = -2x + 44x + 2y = 8 ⇒ 2x + y = 4 ⇒ y = -2x + 4The lines are same as both have same slope and y-intercept.
Correct statement is following:
C. They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.Answer:
C. They are lines that lie exactly on top of one another because they have the same slope and the same y-intercep

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
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
