What is the formula of area of a quadrant?
Answer:
that is, pi (π) multiplied by the radius squared (r2). Now, to calculate the area of a quadrant, divide the area of a circle by 4 (as four quadrants make a circle). We get, Area of a quadrant, A= (πr2)/4 Square units.

General Formulas and Concepts:
Algebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Since we are using substitution, we must replace one variable in 1 equation as the 2nd equation.
We are given:
y = 2x
x + y = 9
Here we see that y equals 2x. We can go ahead and replace in the 2nd equation y.
x + 2x = 9
And we would solve from there.

Jasmine’s grandma gave her $7 to spend at a yogurt stand. The frozen yogurt and toppings cost $0.45 per ounce. She also wants to buy a bottle of water for $2.50. How many x-ounces of yogurt and toppings can Jasmine afford?
Answer:
Jasmine can afford 10 ounces of yogurt and toppings.
Step-by-step explanation:
$7 - $2.50 bottle of water
= $4.50
$4.50 divided by $0.45
= 10 ounces
Reflect the point (4, —1) in (a) the x-axis and (b) the y-axis.
The coordinates of reflected points are:
(a) (4, 1)
(b) (-4, -1)
Use the concept of coordinate points defined as:
A pair of numbers that describe the exact position of a point on a cartesian plane by using horizontal and vertical lines are called the coordinates.
The given points are
(4, -1)
The objective is to find the point of reflection:
(a) Along the X-axis
(b) Along the Y-axis
(a) The reflection along the X-axis,
For the point (4, -1)
x coordinate is 4
y coordinate is -1
Keep the x coordinate the same and take the negative of the y coordinate.
Therefore,
The negative of y coordinate is -(-1) = 1
Hence,
The reflection of the point along x-axis is (4, 1).
(b) The reflection along the Y-axis:
Keep the y coordinate the same and take the negative of the x coordinate.
Therefore,
The negative of x coordinate is -(4) = -4
Hence,
The reflection of the point along y-axis is (-4, -1).

Answer:
Y=5x
Step-by-step explanation:
Y=mx+b, or y=rise/run+starting value
as there is no starting value, we would simply add no variable
rise/run in this equation would 5/1 because when it rises 5, it goes right 1, simplifying that would be 5
Answer:
For each x, the y increases by 10 so ur equation will be y= 5x

Step-by-step explanation:
Answer:
y=-4/3x-60
Step-by-step explanation:
The line intercepts -60 and the slope by using a slope triangle, for y it was from -20 to 20 so 40 units difference, and for x it was -30 to -60 so 30 unit difference. 40/-30 simplified = -4/3

3(2x+6)=x−2
6x+18=x−2(Simplify both sides of the equation)
6x+18+−x=x−2+−x(Add -x to both sides)

Determine if the triangles are congruent. If they are, state how you know.
Answer:
SAS
Step-by-step explanation:
If you flip the first triangle right side up, we can see that they are congruent in the same exact spots. The two sides are congruent, as well as the angle.
Answer:
They are congurrent by SAS criterion. SAS stands for side-angle-side where the angle is in between the 2 lines. In this we can see that 2 lines have been marked as well as the angle in both triangles. SAS is a valid criterion for proving congrurency and therefore these are congurent.

A tanning salon opens with 50 members. Each month the membership increases by 10 members. Write an equation that represents the relationship between the number of months the salon has been opened, x, and the total salon memberships, y?
Answer:
y= 10x+50
Step-by-step explanation:
x is an increasing variable so, if 10 members are joining each month, x equals 10. 50 is a non increasing number so it has no variable. and y equals all members in total, so y= 10x+50

Grace jump 66 times a minute. Zoe jumps 56 times a minute. They both Count Their jumps today and together they jump 1266 times in the total of 21 minutes how long did each girl jump
Answer:
Grace jumped for 9 minutes and Zoe jumped for 12 minutes
Step-by-step explanation:
Let Grace jumped for x minutes and Zoe jumped for y minutes
Grace jump no. of times in 1 minute = 66
Grace jump no. of times in x minutes = 66x
Zoe jump no. of times in 1 minute = 56
Zoe jump no. of times in x minutes = 56x
We are given that Their jumps today and together they jump 1266 times in the total of 21 minutes
So, x+y=21 ----1
66x+56y=1266 ---2
Substitute the value of x from 1 in 2
66(21-y)+56y=1266
y=12
x+y=21
x+12=21
x=21-12
x=9
Hence Grace jumped for 9 minutes and Zoe jumped for 12 minutes
Answer:
Grace jumped for 9 minutes and Zoe jumped for 12 minutes
