Elena's hair has grown in length overall net by. 1.81cm
It is given to us that the average rate at which human hair grows is 1.27 centimeters per month.
Elena allowed her hair to grow for three months, so that's a given. Then she had her hair chopped short by 1.9 cm.
Elena's hair naturally grows at a typical rate.
First, we'll figure out how much Elena's hair has grown in three months, and then from that figure, we'll deduct the length that has been trimmed.
Elena's hair grew 3.x*1.27=3.81 cm in three months.
The amount of hair that was removed was 1.9 cm.
Elena's hair has grown in length by 3.81 cm over the course of three months, minus the length that has been chopped, for a total net growth of 1.91 cm.
Growth in 3 months less the length that was removed is 3.81 – 1.9 = 1.91 cm
Hence, the total net growth of Elena's hair is 1.81cm

The owners of an apartment building bought it new and then 5 years later sold it for $165000. They calculated that the building appreciated $2000 per year while they owned it.
we have to find a linear function that describes the value of the building over time, if a is the age of the apartment building
write a linear function is in slope-intercept form:
y= mx+b
Here, x is the independent variable, and y is the dependent variable. Also, the slope of the line, m, represents some kind of constant rate. Finally, b, the y-intercept represents some sort of starting value for our dependent variable.
165000= $2000*5+b
$165000= $10000+b
$155000=b
f(a)=2000a+155000
therefore f(a)= 2000a +155000 is a linear function that describes the value of the building over time, if a is the age of the apartment building

The graph of f passes through (-9,-8) and is perpendicular to the line whose equation is x = 8.
The equation of the function is
Answer:
y = -8
Step-by-step explanation:
line x = 8 is a vertical line so the line perpendicular has slope of 0
Using m = 0, x = -9, y = -8
y = mx + b
-8 = 0(-9) + b
b = -8
so y = -8
Step-by-step explanation:
y = 8, the one above is correct, we both are.

The second pair represent a unit rate. And the graph is shown.
An ordered pair is a pair made up of two parts that are written inside parantheses and are separated by commas. For instance, the ordered pair (x, y) denotes an ordered pair where "x" is the first member and "y" is the second element. These elements, which can either be variables or constants depending on the context in which they are used, have distinct names.
In an ordered pair, the element order is somewhat significant. It implies that (x, y) may not always be equivalent to (y, x).
When describing a point's location on the coordinate plane with respect to the origin, a coordinate geometry ordered pair is employed.
Hence the graph is attached and the second pair represents the unit rate.

PLEASE ANSWER QUICK!!!! use one of your new conjectures to find the indicated angle measures and expressions.
t + p = ___
Based on the exterior angle theorem, the indicated measures are: t + p = 135°.
What is the Exterior Angle Theorem?In a triangle where an exterior angle is formed outside the triangle by an extended side of the triangle, the exterior angle theorem states that the measure of this exterior angle must be equal to the sum of the two interior angles that are directly opposite this exterior angle.
Angle t and angle p are interior angles of the triangle that are opposite the exterior angle that measures 135 degrees.
This implies that: the sum of angles t and p would be equal to 135 degrees.
Therefore, based on the exterior angle theorem, the indicated measures are: t + p = 135°.

At a cost of $8 per pound, how many ounces of barley can be bought for $3.70?
At a cost of $3.70, we can buy 7.40 ounces of barley.
Given that,
Barley cost per pound = $8
To determine how many ounces of barley can be bought at a cost of $3.70.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
1 pound = 16 ounces
since 1 pound = $8
divide both the side by 16
1 / 16 pound = 8 /16
1 / 16 pound = $0.5
1 ounce = $0.5 cost
Now,
at 1$ = 2 ounces
multiply both sides by $3.70.
3.70 = 2*3.70 ounces
at $3.70 = 7.40 ounces
Thus, at a cost of $3.70, we can buy 7.40 ounces of barley.

A mural measures 145 feet long by 190 feet high. Find the ratio of the height to the perimeter of this mural.
The ratio of height to perimeter of mural is 19:67.
The perimeter of mural will be calculated by the formula -
Perimeter = 2 × (length + breadth)
So, finding the perimeter using the mentioned formula. Keep the values of length and breadth in formula to calculate the perimeter of mural.
Perimeter = 2 × (145 + 190)
Performing addition of values in bracket
Perimeter = 2 × 335
Performing multiplication
Perimeter = 670 feet
Ratio = Height : Perimeter
Ratio = 190 : 670
Cancelling zero to find the ratio
Ratio = 19 : 67

What is the step by step formula for figuring out a home mortgage?
The step by step formula for figuring out a home mortgage is given by the equation: M = P [ i (1 + i )ⁿ ] / [ (1 + i )ⁿ - 1]
A standard mortgage payment means paying back your loan amount and any interest that the bank stated at the time of giving the loan.
It can also include taxes and insurance with your monthly mortgage rate, but this can be calculated separately.
The equation takes into account your total loan payment with the monthly interest rate and the length of time you have to pay off your loan that is the time period. It gives you a fixed monthly mortgage rate.
Therefore, the step by step formula for figuring out a home mortgage is given by the equation: M = P [ i (1 + i )ⁿ ] / [ (1 + i )ⁿ - 1]

The Greens want to put an addition on their house 18 months from now. They will need to save $10,620 in order to achieve this goal. They set aside the same amount each month, and after a year discover they have saved $6,120. The Greens must adjust their plan in order to meet their goal, so they came up with the following options:Option A: Stay with saving the original amount each month but put the addition on one month later than originally plannedOption B: Increase the amount of money they save each month by $120 from their original plan.Which of the following statements is true?
A Only option A will allow them to meet their goal
B Only option B will allow them to meet their goal.
C Both options A and B will allow them to meet their goal.
D Neither option A nor option B will allow them to meet their goal.
Option D. From the question that we have here, we would have it that neither option A or option B would help the Green in order to meet up with the plan that they have.
How to compare the options they haveThe house they want to put an addition on is in 18 months. The amount to be saved is $10620, the total amount saved after a year = 6120
Remember that a year has 12 months, if they are only able to save the above in a year, then in 12 months they cannot meet with the saving target.
Increasing saving by 120 for 18 months = 120 x 18= $2160
This is still below the target.
Hence we would conclude by saying that Neither option A nor option B will allow them to meet their goal.

If Fran were to paint her living room alone, it would take her 5 hours. Her sister Wanda could do the job in 8 hours. How many hours would it take them working together
It would take 3.43 hours to paint living room working together.
In this question, we have been given Fran were to paint her living room alone, it would take her 5 hours. Her sister Wanda could do the job in 8 hours.
We need to find the amount of time required them working together.
Let they need 'x' hours to paint living room together.
So, we get an equation,
1/6 + 1/8 = 1/x
We need to find the value of x.
1/x = (8 + 6) / 48
1/x = 14/48
x = 48 / 14
x = 3.43 hours
Therefore, it would take 3.43 hours to paint living room working together.

Answer:
Parallel lines never intersect, but they must be in the same plane. The definition does not require the undefined term point, but it does require plane. Because they intersect, perpendicular lines must be coplanar; consequently, plane is not required in the definition.

What is the answer to 11 = x/-5 + 8
Answer Formula: x = ?
Answer: x=-15
Step-by-step explanation:
11=x/-5+8
minus 8 on both sides
3=x/-5
multiply by -5 on both sides
x=-15
Answer:
x = -15
Step-by-step explanation:
Given: 11 = x/-5 + 8
We need to get x by itself to make a formula or get an answer
Step 1: Subtract 8 on both sides
We need to subtract 8 on both sides in order to cancel out the 8 on the right and bring it to the left
so, 11 -8 = x/-5 +8 -8 = 3 = x/-5
Step 2: Multiply by -5
We need to multiply by -5 in order to cancel our the -5 on the right and bring it to the left
so, 3*-5=x/-5*5 = -15 = x
Therefore, x = -15.
