Answer:
![1,100 = 1,100](https://tex.z-dn.net/?f=1%2C100%20%3D%201%2C100)
Step-by-step explanation:
Given
1,143 and 1,149
Required
Which of the option is correct
We start by approximating both numbers to nearest digit
<em>1,143; when approximated to nearest hundred is 1,100</em>
<em>1,149; when approximated to nearest hundred is also 1,100</em>
Hence;
1,143 ≅ 1,100
1,149 ≅ 1,100
Comparing both results, we have that
![1,100 = 1,100](https://tex.z-dn.net/?f=1%2C100%20%3D%201%2C100)
From the list of given options, option C is correct;
Step-by-step explanation:
<u>to show how many tickets were sold:</u>
x = upper floor tickets
y = main floor tickets
x + y = 2000
<u>to show total amount of revenue:</u>
25x + 40y = 62,000
<u>Finding answer using both equations:</u>
x + y = 2000
multiply each side by 25
25x + 25y = 2000 × 25
25x + 25y = 50,000
25x + 40y = 62,000
-
25x + 25y = 50,000
-----------------------------------
15y = 12,000
^ this is column subtraction
<em>^ this column subtraction is done to isolate y so we can work with one value rather than 2</em>
15y = 12,000
divide each side by 15
12,000 ÷ 15 = 800
y = 800
x + y = 2000
x + 800 = 2000
x = 1200
Therefore 1200 upper-level tickets were sold
800 main floor tickets were sold
Answer:
Yes for the first, no for the second
Answer:
The answer is A) 12.56 square inches
Step-by-step explanation:
The equation to find the answer is <u>3.14×r²</u>
r standing for radius. To find the diameter, you simply multiply the radius by 2.
Because they already gave us the diameter, the equation to solve this question is <u>3.14×4</u>
<u>3.14×4=</u><u>12.56</u>
The answer is A because when the two lines are on the outside of a term like that it means that what ever is inside is the opposite of the original number
For ex. | 4 | < 4
The 1st number will be a negative so it makes the statement true
