Step-by-step explanation:
Your friend is trying to grow her hair as long as her cousin's hair. The table (attached) shows their hair lengths (in inches) in different months.
a. Write a system of linear equations that represents this situation.
b. Will your friend's hair ever be as long as her cousin's? If so, in what month?
Answer:
a) y = 1/2x + 5/2
y = 2/5x + 29/5
b) hair will be 19 inches for both at 33 months
Step-by-step explanation:
a) rate of growth of friend's hair: (3, 4) (8, 6.5)
(6.5 - 4) ÷ (8 - 3) = 2.5/5 or 1/2
find the y-intercept of equation for growth of friend's hair:
y = mx + b
4 = 1/2(3) + b
4 = 3/2 + b
8/2 - 3/2 = b
5/2 = b
equation for growth of friend's hair:
y = 1/2x + 5/2
rate of growth of cousin's hair: (3, 7) (8, 9)
(9 - 7) ÷ (8 - 3) = 2/5
find the y-intercept of equation for growth of cousin's hair:
y = mx + b
9 = 2/5(8) + b
9 = 16/5 + b
45/5 - 16/5 = b
29/5 = b
equation for growth of cousin's hair:
y = 2/5x + 29/5
b) y = 1/2x + 5/2
y = 2/5x + 29/5
1/2x + 5/2 = 2/5x + 29/5
5/10x + 25/10 = 4/10x + 58/10
1/10x = 33/10
10x = 3300
x = 33
Can someone explain how to solve 3/4 + 7/8 + 1/2 as a mixed number in simplest form
Answer: What you hav to do is to simplify. That’s obvious so let me explain better.
Step-by-step explanation:
3/4 in its simplist form would be 1 1/4 because how many times does three go into four? Only once so it’s 1 and 1/4. Then you repeat this process. 7/8, 1 1/8
btw I hope I, right cuz I’m not the best at math..... sorry if I got it wrong ;-;
Drag each relation to the correct location on the table.
Classify the relations according to whether or not they are functions.
-3x = 15
2y = 10
3x − 0.25y = 3
{(2, 3), (1, 3), (5, 3), (2, 6)}
Reset Next
When we see the given relations we can easily see that 3x-0.25y=3 is the only function and the rest two -3x=15, 2y=10 are not functions.
What is a function?
In a function ,element of x has a corresponding value of y.
How to determine a function?
we have been given three relations as under:
-3x=15
2y=10
3x-0.25y=3
In the first we can only calculate the value of x=-5 but we cannot calculate the value of y.
In he second also we are given only one variable through which we can only determine the value of y.
In the third if we put the value of x then we can determine the value of y easily means each value of x has a corresponding value of y.
Hence 3x-0.25y=3 is the only function among the three.

Chloe needs to swim a total of 9 miles this week. So far this week , she swam 5 5/8 miles. Use the equation 5 5/8 + m =9 to find out how many more miles Chloe needs to swim.
Alright, so all we have to do here is solve the equation!
5 5/8 + m = 9
m = 9 - 5 5/8
Now is the tricky part - doing the subtraction! Let's change 9 to 8 8/8 (which is still equal to 9).
m = 8 8/8 - 5 5/8
Then we can subtract fairly easily!
m = (8 - 5) + (8/8 - 5/8)
m = 3 3/8 miles
Hope this helps!! :)

Can someone please help me find the measure of the exterior angle.
Answer:
X=128°
Step-by-step explanation:
Because an exterior angle of a triangle is equal to of the two opposite interior angle.
The sum of the exterior and interior angle is equal to 180°
In this case the part marked red = 90° because is a right angled triangle.
90+38=128
180- 128=52
180- 52=128
x=128.

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?
A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.
Answer:
To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.
Therefore, the correct selling price is $4.
The manager's likely error was that they set the selling price at the cost (option C).
Step-by-step explanation:
The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of item = $6
Markup = 67%
67% of $6 ⇒ 0.67 x 6 = $4.02
Add the markup in the cost = $6 + $4.02 = $10.02
Round to nearest dollars = $10.2 ≈ $10.
The manager put $4 which is a markup instant of the selling price of $10.
Hence "The correct selling price is $10 and the manager set the selling price at the markup".

Jabari draws figure GHIJ in the coordinate plane. He wants to reflect figure GHIJ across the x-axis to form WXYZ. A. Draw a dashed line to show the line of reflection. B. Show where Jabari should draw figure WXYZ.
To reflect figure GHIJ across the x-axis to form WXYZ, Jabari needs to follow these steps: A. Draw a dashed line to show the line of reflection: To reflect a figure across the x-axis, we draw a dashed line that represents the x-axis.
This line acts as the mirror for the reflection. It is important to note that the line of reflection is perpendicular to the x-axis. B. Show where Jabari should draw figure WXYZ: To create the reflected figure WXYZ, Jabari should locate the corresponding points of each vertex of figure GHIJ across the x-axis.
The corresponding points have the same x-coordinate but opposite y-coordinates. For example, if the coordinates of point G in figure GHIJ are (2,4), then the coordinates of the corresponding point W in figure WXYZ would be (2,-4).
Similarly, for each vertex of figure GHIJ, Jabari should find the corresponding vertex for figure WXYZ by changing the sign of the y-coordinate.
By connecting the corresponding vertices of figure WXYZ, Jabari will form the reflected figure across the x-axis. Remember, the dashed line represents the x-axis, and Jabari should mirror each vertex across this line to create the reflected figure WXYZ.

I think the volume is 31.5.
Step-by-step explanation:
Since you didn't include the original numbers for the base area, I just square rooted 9 because there's no other number other than 1 that you would multiply to get 9. Since volume is L*W*H I put 3 for the w and h (because 3*3 is 9) and then I multiplied 9 by 3.5 or 3 and 1/2 (the same thing) to get 31.5. So the volume is 31.5.
