Answer:
It takes 6 days.
Step-by-step explanation:
First, you have to form expressions for both of them in terms of x. Let x be the number of days :
Ms. W = 400 + 75x
Mrs. Hill = 1000 - 25x
Next, you have to compare it as we want to find out how many days in takes for them to have the same number of followers :
400 + 75x = 1000 - 25x
75x + 25x = 1000 - 400
100x = 600
x = 6

Line l is a perpendicular bisector of line segment R T. It intersects line segment R T at point X. Line l also contains point S.
Which line segment has the same measure as ST?
RX
TX
SR
XS
Answer:
SR
Step-by-step explanation:
The segment that has the same measure as ST is SR
What are line segments?Lines segments with the same measures have the same lengths
From the question, we have the following highlights
Line segment I bisects line segment RT at point XLine segment I contains point SThe highlight (I) above means that:
Line segments RX and SX are congruent
Given that:
Line segment I contains point S
Then it means that:
Line segments ST and SR are congruent
Hence, the segment that has the same measure as ST is SR

Correct Question:
To find of :
∠QSR∠QExplanation:
∠QSR+∠QRT=180⁰
Reason:
linear pair
.°. ∠QSR+114⁰=180⁰
∠QSR=180⁰-114⁰
∠QSR=66⁰
Can also be done as follows:
To find value of ∠QSR first we have to find y
y⁰+(5y)⁰=114
Reason:
exterior opposite angle is equal to sum of interior angles
6y=114
y=114/6
y=19
y⁰+(5y)⁰+∠QSR=180⁰
Reason:
sum of angles of triangle =180⁰
6y+∠QSR=180⁰
6×19+∠QSR=180⁰
114+∠QSR=180⁰
∠QSR=180⁰-114⁰
∠QSR=66⁰
From second part we get the value of y

Will give brainliest find the slope.
Answer:
-1/10 for first one and -4/2 for second one
Step-by-step explanation:
lol can I have brainliest?
Hello!
Okay, so: To find the slope, you can use the slope formula: y2-y1/x2-x1...
Let's begin.
Start by plugging in given values into the formula. We can see from looking at the chart that,
y2 = -2
y1 = 3
x2 = 2
x1 = -8
Those are for set 1. So, Let's plug these values into the slope formula:
-2 - 3/2 - (-8)
Subtract
-5/10
Now divide
-1/2 or -0.5
Okay, now let's move on to Set 2.
Set 2:
We're going to do the exact same thing here that we did earlier. Given from the chart:
y2 = -3
y1 = -1
x2 = -2
x1 = 4
Plug them into the formula:
-3 - (-1) / -2 - 4
Subtract
-2 / -6
Divide
1/3
So, for set 1, the slope is -1/2. For set 2, the slope is 1/3.
If an equilateral triangle has a side lengths of 8 units , what is the height of the triangle
Answer:
8
Step-by-step explanation: each side is equal so 8
The height of the equilateral triangle for the given side length is equal to ( 4√3 ) units or approximately 6.93 units (rounded to two decimal places).
In an equilateral triangle, the height is the line segment perpendicular to one side of the triangle and passing through the opposite vertex.
For an equilateral triangle with side length "s," the height "h" can be calculated using the formula:
h = ( √3 / 2) × 8
Where "s" is the side length of the equilateral triangle.
Here, the side length of the equilateral triangle is given as 8 units.
So, substituting the value of "s" into the formula:
⇒ h = ( √3 / 2) × 8
⇒ h = ( 8√3 / 2)
⇒ h = ( 4√3 ) units
Therefore, the height of the equilateral triangle is ( 4√3 ) units or approximately 6.93 units (rounded to two decimal places).

In AXYZ, P is the centroid and YC = 15.
Find the length of YZ
PLEASE HELP!
Answer:
YZ = 30
Step-by-step explanation:
In Δ XYZ
∵ P is the centroid
∴ XC, YB, and ZA are the medians of the triangle
∵ Each median bisects its base
∴ A is the mid-point of XY
∴ B is the mid-point of XZ
∴ C is the mid-point of YZ
∵ C is the mid-point of YZ
∴ YC = ZC
∵ YC = 15
∴ ZC = 15
∵ YZ = YC + ZC
∴ YZ = 15 + 15
∴ YZ = 30
∴ The length of YZ is 30
Cat has a budget of $50 for school supplies. He needs to buy 5 binders, which cost $7 each. He plans to spend his remaining money on pencils, which cost $2 each. Set-up and solve Enano quality to determine how many pencils pet can buy.
Answer:
The least amount of pencils that can be bought is 7
Step-by-step explanation:
Step one:
Budget=$50
the cost of one binder= $7
then 5 binders will cost= 7*5= $35
the balance will be 50-35= $15
Step two:
let the number of pencils that can be bought be x
The cost of each pencil = $2
the remaining amount from the budget to get pencils is $15
Hence the number of pencils that can be bought is
x=15/2
x=7.5
The least amount of pencils that can be bought is 7
f(x) = 3x + 5
g(x) = 4x^2 – 2
h(x) = x^2 – 3x + 1
Find f(x) – g(x) – h(x).
Answer:
f(x) – g(x) – h(x) = -5x^2 + 6x + 6
Step-by-step explanation:
Copy f(x) as is: f(x) = 3x + 5
Negate g(x): -g(x) = -4x^2 + 2
Negate h(x): -h(x) = -x^2 + 3x - 1
Now combine like terms:
f(x) – g(x) – h(x) = -5x^2 + 6x + 6
What is 2M?
M=[3 5]
[-4 0]
Answer:
2M will be:
[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Therefore, the 2nd option is true.
Step-by-step explanation:
Given the matrix
[tex]M=\begin{pmatrix}3&5\\ -4&0\end{pmatrix}[/tex]
Multiplying by 2 will basically be a scalar multiplication.
Therefore, multiply each of the matrix elements by a scalar.
[tex]2M=2\begin{pmatrix}3&5\\ \:-4&0\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}2\cdot \:3&2\cdot \:5\\ 2\left(-4\right)&2\cdot \:0\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Hence, 2M will be:
[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Therefore, the 2nd option is true.

The volume of the large cube is 125 cubic inches. The volume of the small cube is 27 inches. What is the difference between the length of one side of the large cube and the length of one side of the small cube?
Answer:
2cmStep-by-step explanation:
Step one:
given data
for the large cube
the volume= 125cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
125=l^3
l=∛125
l=5cm
Step two:
given data
for the large cube
the volume= 27cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
27=l^3
l=∛27
l=3cm
The difference between the length of one side of the large cube and the length of one side of the small cube=5-3= 2cmHelp!!!!

A. The lines are parallel.
B. The lines are coincident.
C. Both lines intersect but are neither parallel nor perpendicular.
D. The lines are perpendicular.
9514 1404 393
Answer:
D. The lines are perpendicular
Step-by-step explanation:
The first line has a rise of (1-2) = -1 for a run of (5-(-3)) = 8.
The second line has a rise of (-1-7) = -8 for a run of (1-2) = -1.
Then the slopes are -1/8 and -8/-1 = 8, which are negative reciprocals of each other. Lines with slopes having that relationship are perpendicular.
