Answer:
k = 100/9
Step-by-step explanation:
In this question, we will be solving for "k".
Solve:
9/10 = 10/k
Cross multiply.
(9 · k) = (10 · 10)
9k = 100
Divide both sides by 9
k = 100/9
Your answer would be k = 100/9
Can some one explain what an arithmetic sequence is...?
Answer:
An arithmetic sequence is an infinately long set of numbers that increase by a certain amount(this amount is called the common difference) every number. for example, 1,2,3,4,5... is an arithmetic sequence with a common difference of one.
Try finding how many meters they travel in ONE second) Mai and Priya were on scooters. Mai traveled 15 meters in 6 seconds. Priya travels 22 meters in 10 seconds.
Answer:
Mai travels 2.5 meters in 1 second
Priya travels 2.2 meters in 1 second
Step-by-step explanation:
Try finding how many meters they travel in ONE second) Mai and Priya were on scooters.
For Mai
Mai traveled 15 meters in 6 seconds.
Hence,
6 seconds = 15 meters
1 second = x meters
Cross Multiply
6x = 15 meters
x = 15/6
x = 2.5 meters
Hence, Mai travels 2.5 meters in 1 second
For Priya
Priya travels 22 meters in 10 seconds.
Hence,
10 seconds = 22 meters
1 second = x meters
Cross Multiply
10x = 22 meters
x = 22/10
x = 2.2 meters
Hence, Priya travels 2.2 meters in 1 second
| n-3 |=2 solve and show work please
Answer:
n = 5 ; n = -1
Step-by-step explanation:
n - 3 = 2
When you transfer (-3) to the other side of the equation, it turns into (+3).
n = 2 + 3
Evaluate.
n = 5
n + 3 = 2
When you transfer (+3) to the other side of the equation, it turns into (-3).
n = 2 - 3
Evaluate.

What are the roots of the polynomial equation: 4k - 144 = 0 Show all of your work!
Answer:
k = ±6
Step-by-step explanation:
guess your question is 4k²–144 = 0??
4k² = 144
k² = 36
k²–36 = 0
(k+6)(k–6) = 0
k+6 = 0 | k–6 = 0
k = –6, k = 6.
Alternatively; k = ±6.

A cube has sides of length 5 cm.
Find the total surface area of the cube.
Please explain as well, as I struggle with surface area.
Answer:
150 cm^2
Step-by-step explanation:
Keep in mind that the dimensions of the cube are identical in 6 directions. This means that the surface area of the bottom is 5 cm by 5 cm, yielding the area 25 cm^2. The top has the same area, so considering top and bottom we get a total surface area of 50 cm^2.
Likewise, the total surface area of the sides together is 50 cm^2. The total surface area of the front and back together is 50 cm^2.
Thus, the total surface area of the entirre cube is 3(50 cm^2), or 150 cm^2

A cuboid with a volume of 924cm^3 has dimensions 4cm, (x+1)cm and (x+11). Show clearly that x^2+12x-220=0 solve the equation by factorisation, making sure you show the factorisation. Finally, find the dimensions of the cuboid,
Answer:
[tex]x^2+12x-220=0[/tex] -- Proved
[tex]x = 10\ \ \ x = -22[/tex]
Step-by-step explanation:
Given
[tex]Volume = 924cm^3[/tex]
[tex]Dimension: 4cm; (x+1)cm; (x+11)cm[/tex]
Required
Show that [tex]x^2+12x-220=0[/tex]
The volume is calculated as:
[tex]4 * (x + 1) * (x + 11) = 924[/tex]
Open the brackets
[tex](4x + 4) * (x + 11) = 924[/tex]
[tex]4x^2 + 44x + 4x + 44 = 924[/tex]
[tex]4x^2 + 48x+ 44 = 924[/tex]
Collect Like Terms
[tex]4x^2 + 48x+ 44 - 924=0[/tex]
[tex]4x^2 + 48x -880=0[/tex]
Divide through by 4
[tex]\frac{4x^2}{4} + \frac{48x}{4} -\frac{880}{4}=0[/tex]
[tex]x^2+12x-220=0[/tex]
Solving further:
Expand the expression
[tex]x^2 + 22x - 10x - 220 = 0[/tex]
Factorize:
[tex]x(x + 22) - 10(x + 22) = 0[/tex]
[tex](x - 10)(x + 22) = 0[/tex]
Split:
[tex]x - 10 = 0;\ \ \ x + 22 = 0[/tex]
[tex]x = 10\ \ \ x = -22[/tex]

Answer:
y = -y
Step-by-step explanation
So since we know that the answer of this question turns out to be a positive, and 5 is a negative number, that means y is negative. Heres my reason why:
( write this down on your essay)
Since a negative number and another negative number added becomes a positive, y would be a negative number.
Therefore, It is true that y is a negative number

Point A has coordinates (6,4) and point B has coordinates (2,7) write AB as column vector. Plz plz plz
Answer:
[tex]\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}[/tex]
Step-by-step explanation:
Column Vector
Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.
It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).
The vector directed from A to B is found by subtracting its corresponding coordinates:
[tex]\overrightarrow{AB }=<2-6,7-4>[/tex]
[tex]\overrightarrow{AB }=<-4,3>[/tex]
Now we express the vector as a one-column matrix as follows:
[tex]\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}[/tex]

pls help I'm being timed
Answer:
It would cost $ 408.04 to travel 2727 miles
Divide total miles by miles per gallon:
2,727 / 27 = 101 gallons.
Multiply total gallons by price per gallon:
101 x 4.04 = $408.04 Round as needed.

-12x– 2y =4
Answer:
The system has of the equation has no solution
Thus,
NO SOLUTION!
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}y=-6x+2\\ -12x-2y=4\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y+6x=2\\ -2y-12x=4\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}y+6x=2\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y+12x=4[/tex]
so
[tex]\begin{bmatrix}2y+12x=4\\ -2y-12x=4\end{bmatrix}[/tex]
adding both equations
[tex]-2y-12x=4[/tex]
[tex]+[/tex]
[tex]\underline{2y+12x=4}[/tex]
[tex]0=8[/tex]
so
[tex]\begin{bmatrix}2y+12x=4\\ 0=8\end{bmatrix}[/tex]
0 = 8 is false, therefore the system has of the equation has no solution
Thus,
NO SOLUTION!

given STU and DEF , what is m < U ?
can i get help i posted this twice now.
Answer:
u=47
Step-by-step explanation:
...................
The measure of angle U is 74 degrees.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
to determine the measure of angle U:
From the question, we have the following parameters that can be used in our computation:
△PQR ≅ △STU
If m ∠P = 62 degrees and m ∠Q = 45 degrees
The above parameters mean that
P = S Q = T and R = U
So, we have
U = R = 180 - P - Q -- by the angles in a triangle theorem
So, we have
U = 180 - 61 - 45
= 74
Evaluate
U = 74
Hence, the value of m ∠U is 74 degrees
