❄ Hi there,
let us revise the rounding rules and then, get down to rounding the number.
[tex]\sf{Rounding \ Rules:}[/tex]
If the number you need to round is followed by a number from 0 to 4, you round down.If the number you need to round is followed by a number that's 5 or more, you round up.Now we can start the rounding process.
Reading the problem & the directions, we notice that we need to round to 3 decimal places (3 numbers after the decimal point).
Looking at the fourth number, we notice that it's less than 5.
∴ we need to round down ↡

What is expression in mathematics?An expression in mathematics is a combination of terms both constants and variables.
Given are two labelled bars shown next to each other and each bar.
3 of the 8 bars are colored. Using fraction, we can represent it as -
{f} = 3/8
There are two such bars, so we can write -
y = 2{f}
y = 2 x 3/8
Therefore, the expression that is represented by the model below is -
y = 2 x 3/8.

2x-6y=12 and -5x+15y=-30 elimination
Answer:
unsolvable because the second equation is just -2.5 times the first equation.
Step-by-step explanation:
2x-6y=12 then 2x=12+6y x=6+3y
-5x+15y=-30
substitute x
-5(6+3y)+15y=-30
-30-15y+15y=-30

A store has apples on sale for $21.00 for 6 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $126.00? Complete the explanation.
Answer:
115 apples
Step-by-step explanation:
6 pounds of apple = $21.00
Cost per pound :
$21.00 / 6 = $3.5 per Pound
1 pound = 16 ounces
16 ounces cost $3.5
1 ounce = $3.5 / 16 = $0.21875
5 ounces will cost :
5 * 0.21875 = $1.09375
Number of 5 ounce apple that can be purchased with $126
$126 / $1.09375
= 115.2
Approximately 115 apples

m=y2-y1/x2-x1
m=19-10/6-3
m=3
Answer: The answer is C which is "m = 3"
Step-by-step explanation: To find the slope, the formula is change of y / change of x. The change of y in the graph is 9, and the change of x is 3. 9 divided by 3 is 3. Therefore, the option "m=3" is the correct answer.

Im a little lazy and i dont feel good so someone answer this please
There are 99 males and 121 females participating in a marathon. What percent of the participants are female?
To do this, we first want to see how many participants there are in total by adding both males and females.
[tex]99+121=220[/tex]
Now we know that there were 220 total participants, but only 121 were females.
This allows us to set up the fraction 121/220= the percent female.
[tex]\frac{121}{220} =0.55[/tex]
or 55%
Two lines A and B are parallel if both lines are rotated 90° in the same direction and then translated to the right by the same number of units which statement about the lines resulting from these transformations is true
Answer:
A' and B' will be parallel. (See Explanation)
Step-by-step explanation:
Given
Parallel lines: A and B
Rotation: 90° same direction
Translation: Right (same units)
Required
Describe the result of the transformation
No options were given. So, I will answer on general terms.
From the question, we can see that, the same transformation that was performed on line A was also done on line B.
This means that both lines will maintain the initial relationship between them.
Initially, A and B are parallel.
After the transformation, A' and B' will be parallel.
Answer:They will be the same line
Step-by-step explanation:I did this on my test it’s correct
