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.

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

Carlos is three times as old his son. The sum of Carlos age and his sons age is 52. How old is Carlo
Answer:
39
Step-by-step explanation:
Let x = son's age
Then 3x = Carlos' age
So, x + 3x = 52
4x=52
x=13
So the son is 13 and Carlos is 3x13=39

Answer:
Begin by finding the area of the square, 24x22. This would equal 528. Then, we need to find the area of each circle using the area formula, [tex]\pi[/tex][tex]r^{2}[/tex]. We can plug in the numbers to get [tex]\pi[/tex][tex]3^{2}[/tex]. Multiply 3x3 to get 9[tex]\pi[/tex]. Because there are 4 circular burners, we need to multiply 9[tex]\pi[/tex] by 4 to get 36[tex]\pi[/tex] or 113.04. Now, we can subtract 528 with 113.04 to result with 414.96 or 415, when rounded. So, the answer would be 415 [tex]in.^{2}[/tex]

Graph the line with slope 2 and y-intercept - 7.
Answer:
you start on the y axis at -7 and you go up 2 and to the right 1
To graph the line with a slope of 2 and a y-intercept of -7, we can follow these steps .
The steps to be followed.1. Plot the y-intercept - Start by marking the point (0, -7) on the coordinate plane. This represents the y-intercept, which is the point where the line intersects the y-axis.
2. Use the slope to find additional points - Since the slope is 2, it means that for every 1 unit increase in the x-coordinate, the y-coordinate increases by 2 units.
This gives us a rise of 2 and a run of 1. Starting from the y-intercept, move up 2 units and right 1 unit to find the next point. Repeat this process to find more points.
3. Connect the points - Once you have a few points, draw a straight line through them. Since the slope is positive (2), the line will slant upward from left to right.
The resulting line should be a straight line that goes through the point (0, -7) and has a positive slope of 2. See the attacghed.

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
