Answer:
y=45
Step-by-step explanation:
Let's solve your equation step-by-step.
10 y = 2 /9
Step 1: Cross-multiply.
10 y = 2 /9
(10)*(9)=2*y
90=2y
Step 2: Flip the equation.
2y=90
Step 3: Divide both sides by 2.
2y /2 = 90 /2
y=45
brainliest please?
Answer:
y = 45
Step-by-step explanation:
10/y=2/9
10 = y * 2/9
10 = 2/9y
10 * 9 = 2/9y * 9
90 = 2y
90/2 = 2y/2
y = 45
ps: * means multiply

Answer:
84° 125°Step-by-step explanation:
Sum of the interior angles of a regular polygon:
S(n) = 180°(n - 2), where n- number of sidesExercise 4Pentagon has sum of angles:
S(5) = 180°(5 - 2) = 540°Sum the given angles and find x:
x° + 122° + 100° + 90° + 144° = 540°x° + 456° = 540°x° = 540° - 456°x° = 84°Exercise 5Hexagon has sum of angles:
S(6) = 180°(6 - 2) = 720°Sum the given angles and find x:
x° + 110° + 160° + 105° + 105° + 115° = 720°x° + 595° = 720°x° = 720° - 595°x° = 125°An art gallery is increasing the asking price of its paintings by 60%. A painting now costs $400.00. How much was the painting before the increase??

A line that includes the points (-2, c) and (-1, 10) has a slope of 2. What is
the value of c?
Answer:
8
Step-by-step explanation:
m = (Y2-Y1) ÷ (X2- X1) 2 = (10-c) ÷ (-1-(-2)) 2 = (10-c) ÷( 1)2= 10-cc = 10-2c= 8(-2,c) and (-1,10)
10-c
-1--2
10-c
1
We need the fraction to be 2, or 2/1. The bottom number is 1, so we technically already have the answer. But we still need to plug in a number for c. To get 2, we need to subtract 8 from 10.
So c is 8.

How do we find the factors of x2 – 64
Find numbers that multiply to be O but adds to be -64
O Find numbers that multiply to be 1 but adds to be -64
Find numbers that multiply to be -64 but adds to be 1
Find numbers that multiply to be -64 but adds to be 0
Answer:
The factors of x²-64 is equal to (x-8)(x+8).
Step-by-step explanation:
The given expression is:
x²-64
we know that, 8² = 64
So,
(x²-8²) = (x-8)(x+8) [As (a-b)(a+b) = a²-b²]
So, the factors of x²-64 i equal to (x-8)(x+8).

It is 1/2 mile from the students home to a store and back. In a week, she walked to the store and back home 1 time. In the same week, she rode her bike to the store and back 3 times. How many miles did she walk and ride to the store and back in that week?
Answer:
2
Step-by-step explanation:
So you will get the 1/2 and see how many times she does go back and forth and she did it 4 times so you would multiply 1/2 x 4 and get a total of 2
Hope It Helps
Answer:
2
Step-by-step explanation:
she walked to the store and back 1 time=1/2 mile :
from her house to the store=1/4 mile
she rode her bike to the store and back 3 times
So in total that week she went to the store and back 4 times
so 4 times 1/2 is 2
The drawing shows a semicircular window separated into 3 sections of colored glass

What is the area of a sector? What is a expression? What is a mathematical equation?A part of a circle is called sector. The area of a sector is given by -(Ф/360) x πr²
A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the given semicircle as shown in image.
Total green coloured area -
A[G] = 2 x {(Ф/360) x πr²}
A[G] = 2 x (40/360 x πr²}
A[G] = (2/9)πr²
Now -
A[R] = πr²/2 - (2/9)πr²
A[R] = πr²{1/2 - 2/9}
A[R]% = (πr²{1/2 - 2/9}/πr²) x 100
A[R]% = (1/2 - 2/9) x 100
A[R]% = (9 - 4)/18 x 100
A[R]% = 5/18 x 100
A[R]% = 500/18
A[R]% = 27.78%
Therefore, 27.78% of the total area is covered with red.

Questions (a,b), 1 (a,b)
a )
First of all we need to find the value of x ,
because the angles are written in terms of the variable x .
______________________________________
Let's find the value of x :STV angle & SUV angle have same measure because both of them are the front angle of SV arc .
[tex]STV angle \: = SUV angle \: \: = \frac{SV \: arc}{2} \\ [/tex]
So :
[tex]3x - 5 = 2x + 15[/tex]
Add sides 5
[tex]3x - 5 + 5 = 2x + 15 + 5[/tex]
[tex]3x = 2x + 20[/tex]
Subtract sides minus 2x
[tex]3x - 2x = 2x + 20 - 2x[/tex]
Collect like terms
[tex]x = 2x - 2x + 20[/tex]
[tex]x = 20[/tex]
Thus the measure of angle T equals :
[tex]measure \: of \: angle \: T = 3x - 5 \\ [/tex]
Now just need to put the value of x which we found :
[tex]measure \: of \: angle \: T \: = 3 \times (20) - 5 \\ [/tex]
[tex]measure \: of \: angle \: T \: = 60 - 5[/tex]
[tex]measure \: of \: angle \: T \: = 55°[/tex]
♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡♡
b )
angle S & angle V are also have same measure because they both are the front angles to the TU arc .
And we need to find the value of x again in this part exactly like we did for a .
[tex]angle \: \: S = angle \: \: V[/tex]
As the question told :
[tex]angle \: \: S = 3x[/tex]
and ,
[tex]angle \: \: V = x + 16[/tex]
Thus :
[tex]3x = x + 16[/tex]
Subtract sides minus x
[tex]3x - x = x + 16 - x[/tex]
Collect like terms
[tex]2x = x - x + 16[/tex]
[tex]2x = 16[/tex]
Divide sides by 2
[tex] \frac{2x}{2} = \frac{16}{2} \\ [/tex]
Simplification
[tex]x = 8[/tex]
So ;
[tex]measure \: \: of \: \: angle \: \: S = 3x[/tex]
[tex]measure \: \: of \: \: angle \: \: S = 3(8)[/tex]
[tex]measure \: \: of \: \: angle \: \: S = 24°[/tex]
And we're done.

Mark the focus of the parabola you are going to create at F(6, 4). Draw a horizontal line that is 6 units below the focus. This line will be the directrix of your parabola. What is the equation of the line?
Answer: y=-2
Step-by-step explanation:
Based on the location of the line and the focus of the parabola, the equation of the line will be y = -2.
What is the equation of the line?The line is a horizontal line which means that the primary focus will be on the y axis.
The focus of the parabola is at F(6, 4) and the line is to be 6 units below this focus which means that the line on the y axis will be at:
= 4 - 6
= -2
This leaves the formula of the line as y = -2.
