Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer.1 inch ≈ 1.578 × 10 -5 miles.
Answer: The number of inches in 1225 miles is [tex]7.763\times 10^7[/tex]
Step-by-step explanation:
Scientific notation is defined as the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.
Example: 3000 is written as [tex]3.0\times 10^3[/tex]
Given : [tex]1.578\times 10^{-5}[/tex] miles = 1 inch
Thus 1 mile = [tex]\frac{1}{1.578\times 10^{-5}}=0.634\times 10^5[/tex] inches
1225 miles = [tex]\frac{0.634\times 10^5}{1}\times 1225=776.3\times 10^{5}=7.763\times 10^7[/tex] inches

The students will paint 4 rooms on the first floor and the conference room on the second floor. Each room on the first-floor room is 4m x 5m.
1. Calculate the area of one of the rooms.
Answer:
20m
Step-by-step explanation:
The rooms are 4m x 5m.
To find the area, multiply length by width: 4*5=20
The Area of one room is 20 m².
What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
Given:
First, Area of one room= lw
= 4 x 5
= 20 m²
Now, Area of four room = 4 x 20
= 80 m²
Thus, area of one room is 20 m².

A five feet tall man casts a shadow rhat is 4 1/3 feet long. A telephone pole casts a shadow that is 25.5 feet long. How tall is the telephone pole in inches
Answer:
22.1 inches
Step-by-step explanation:
The shadow is formed at a specific factor of the original image hence if a 5 feet tall man casts a shadow rhat is 4 1/3 feet long then a telephone pole casts a shadow that is 25.5 feet long must have a length
5 / 4 1/3 = x / 25.5
where x is the length of the pole
5 / 13/3 = x/ 25.5
15/13 = x/25.5
cross multiply
15 * x = 13 * 25.5
Divide both sides by 15
x = 13 * 25.5 / 15
x = 22.1 inches
The telephone pole in inches is 22.1 long

Answer: 36 and 56
Step-by-step explanation: the sum of two numbers translates into x + y = 92
If the difference would be 0 then the numbers would be equal.
Just choose which number you want to be bigger. If x is bigger then x - y = 20. If y is bigger then y - x = 20.
Let’s make x bigger so x-y=20. You can go two ways with this.
Either x=20+y because when passing one term from one side to the other you can change the sign.
Or y=x-20 because you pass “-y” to the right and it’s becomes “y” and you pass 20 to the left and it becomes -20.
Let’s go with y=x-20.
Now we replace this in the other relation:
X + Y = 92
X + (x-20) = 92
X + X - 20 = 92
2x - 20 = 92 ==> 2x = 92 + 20 ==> 2x = 112 ==> 112/2 ==> x=56
Y = x - 20 ==> y = 56 - 20 ==> y = 36.
If you choose x=20+y and replace x in the other relation you’ll find out y first and only after that you’ll find x.
