The Cost C (in dollars) of making n bracelets is represented by C=45n+125. How many bracelets are made when the cost is $845?
Answers
So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.
845 = 45n + 125.
Subtract from both sides:
845-125 = 45n + 125-125
720 = 45n
Divide by 45:
720 / 45 = 45n / 45
16 = n
This means that 16 bracelets can be made if the cost is 845.
We can also re-input the information into the equation to be extra sure!
845 = 45 (16) + 125.
845 = 720 + 125.
845 = 845
Yes!
I hope this helps! :)

Transformation is a method required to resize or change the orientation of a given shape or figure. The required answer is:
i. Statements b and d would map Shape l onto Shape IIii. Statements a, c, e, and f does not map Shape l onto Shape IITransformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation.Translation is a method that requires moving every point in a given shape in the same direction and same unit.
Reflection is a method that involves flipping a given figure about a given reference point or line. Rotation is a method that required turning a given figure at an angle about a reference point. Dilation is a method in which the length of the sides of the figure is either increased or decreased.Thus the answers to the question are listed as follows:
a. a reflection across the y-axis, followed by a 90° clockwise rotation about the origin, and then a translation left 18 units. Does not Map Shape l onto Shape IIb. a 90° clockwise rotation about the origin and then a translation left 18 units Answer: Maps Shape l onto Shape IIc. a 90° counterclockwise rotation about the origin, followed by a reflection across the y-axis, and then a translation left 18 units d.

Mr. Reynolds is a rancher. He started with a 150 cows in his herd. Due to a hole in his fence, he now has 120 cows in his herd. By what percentage was the number of cows in Mr. Reynold's herd reduced?
Answers
Answer:
20%
Step-by-step explanation:
Therefore, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of [tex]100[/tex]. It is often denoted using the percent sign, "%".
Here given that,
Mr. Reynolds is a rancher. He started with a [tex]150[/tex] cows in his herd. Due to a hole in his fence, he now has [tex]120[/tex] cows in his herd.
Number of cows Mr. Reynolds have
[tex]\frac{120}{150}[/tex] ×[tex]100=80[/tex] %
So, the number of cows Mr. Reynolds reduced is
[tex]100[/tex] % - [tex]80[/tex] % = [tex]20[/tex] %
Hence, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.

what is 159,095 rounded to the nearest hundred?
Answers
Answer:
159,100 is the answer
Step-by-step explanation:
159,100 is the answer because 159,095 is closest to 159,100 than 159,000. So therefore, 159,100 is the answer.
Answer:
159,100
Step-by-step explanation:
200,000 - rounded to the nearest hundred thousands
160,00 - rounded to the nearest ten thousands
159,00 - rounded to the nearest thousands
159,100 - rounded to the nearest hundreds
159,100 - rounded to nearest tens
159,095 - rounded to nearest ones
While rounding off to the nearest hundred, if the digit in the tens place is between 0 – 4 i.e. < 5, then the tens place is replaced by ‘0’.
If the digit in the units place is equal to or >5, then the tens place is replaced by ‘0’ and the hundreds place is increased by 1.
Which graph shows the correct solution to the inequality below?
Answers
Answer:
Third Option
Step-by-step explanation:
3x + 18 > 6x - 9
We have to find the value of x for this
Subtract 18 from both sides to leave 3x alone
3x > 6x - 27
Subtract 6x from both sides to be able to find the value of x
-3x > -27
Divide by -3 on both sides
x > 9
The answer would be the third option, since X is anything greater than 9
