Esmeralda Hasn't backed it in the shape of the screw is side of the magnet to 3 inches on what is the perimeter of her magnet
Answer:
12 INCHES
Step-by-step explanation:
Esmeralda has as magnet in the shape of a square each side is 3 inches long what is the perimeter?
A square is a quadrilateral with four equal sides.
Characteristics of a square includes:
• The diagonals bisect each other at 90°.
• Opposite sides parallel and of equal length
• The four angles of a square are equal.
perimeter of a square = 4 x length
4 x 3 = 12 inches

(05.05) Polygon ABCD has the following vertices:
A(−5, 4), B(1, 4), C(6, −4), and D(−5, −4)
Calculate the area of the polygon.
A) 48 units squared
B) 53 units squared
C) 68 units squared
D) 88 units squared
Answer:
B hope this helps!
Step-by-step explanation:
Trust <3
Answer:
The first thing you should do is draw the points in the Cartesian plane and then join them to find the polygon.
The searched polygon can be seen in the attached image.
The area of the polygon will be the area of the square plus the area of the triangle.
At = (6) * (8) + (1/2) * (5) * (8) = 68
At = 68
answer
the area of the polygon is 68units ^ 2
if a and b are roots of 3x2-6+2=0then find a+b
Answer:
a + b = 2
Step-by-step explanation:
Given
ax² + bx + c = 0 ( equation in standard form )
Then the sum of the roots = - [tex]\frac{b}{a}[/tex]
3x² - 6x + 2 = 0 ← is in standard form
with a = 3, b = - 6 , then
sum of roots = - [tex]\frac{-6}{3}[/tex] = 2
Answer:
[tex]I \ think \ it \ is \ 6x\\\\3x^2 - 6x +2 = 0\\\\[/tex]
[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2a} \\\\a = 3, b = -6, c = 2\\\\x = \frac{-b + \sqrt{b^2 - 4*a*c} }{2a}, x = \frac{-b - \sqrt{b^2 - 4*a*c} }{2a} \\\\ \\\\x = \frac{6 + \sqrt{36 - 24} }{6} , x = \frac{6-\sqrt{36 -24} }{6} \\\\[/tex]
[tex]x = \frac{6+\sqrt{12} }{6} , x = \frac{6-\sqrt{12} }{6} \\\\x = \frac{3+\sqrt{3} }{3} , x = \frac{3-\sqrt{3} }{3}[/tex]
[tex]Let \ a = \frac{3 + \sqrt{3} }{3} , b = \frac{3-\sqrt{3} }{3} \\\\a + b = \frac{3+\sqrt{3} }{3} + \frac{3-\sqrt{3} }{3} = \frac{3+\sqrt{3} +3-\sqrt{3} }{3} = \frac{6}{3} = 2[/tex]
A circle has a radius of 1.5 meters.
Find its circumference and area.
help bestiess :)
Answer:
C=9.42
Step-by-step explanation:
Formulas: C=2πr or C=πd
Were gonna use C=2πr
"r"stands for radius from the problem we know that the radius is 1.5 .
Now we substitute the "r" for 1.5, it looks like this C=2π1.5 .
Now we multiply 2x1.5=3 . Now you are left with C=3π
Now you need to multiply 3xπ (Instead of π use 3.14) it would look like this 3x3.14= 9.42

Shows the termination of the parking lot of Helen healings health food store parking lot is how many square yards
Answer:
1100 yd²
Step-by-step explanation:
The parking lot can be divided into 2 rectangles :
Area of a rectangle = Length * Width
First rectangle :
Dimension = 40 yards by 20 yards
Area = 40 * 20 = 800 yd²
Rectangule 2 :
30 yards by 10 yards
Area = 30 * 20
Area = 30 * 10 = 300 yd²
Total area of parking lot :
800 + 300 yd²
= 1100 yd²
A cone and cylinder each have a height of 10 inches and a radius of 5 inches. If you filled the cone completely with water and poured it into the cylinder. How many times would it take until the cylinder is completely full with water?
Answer:
The times that would take until the cylinder is completely full with water by the cone are:
3 times.Step-by-step explanation:
To identify how many times we must fill a cone to fill completely a cylinder with the same height and radius, we must calculate the volume of the two containers and next divide the volume of the cylinder by the volume of the cone. To obtain the volume of the cylinder we can use the next formula:
Volume of a cylinder = [tex]\pi[/tex] * [tex]radius^{2}[/tex] * [tex]height[/tex]If we replace the values in the formula, we obtain:
Volume of a cylinder = [tex]\pi[/tex] *(5 inches)^2 * 10 inchesVolume of a cylinder = 785.4 inches^3 approximately.Now, we're gonna calculate the volume of the cone with the next formula:
Volume of a cone = [tex]\frac{\pi*radius^{2}*height }{3}[/tex]As you can see just with the formula, The volume of a cone is three times less than that of a cylinder (because we add the dividend 3 to it), but we're gonna replace and prove it:
Volume of a cone = [[tex]\pi[/tex] *(5 inches)^2 * 10 inches] / 3Volume of a cone = [785.4 inches^3] / 3Volume of a cone = 261.8 inches^3 approximately.And, if we divide the two volumes to obtain the times we need to fill the cone to fill completely the cylinder:
Times we need to fill the cone = 785.4 / 261.8Times we need to fill the cone = 3By this reason, you must fill completely a cone 3 times to fill completely a cylinder with the same radius and height.
Solve for X
x = ___ (Round to the nearest hundredth)
Answer:
12.62
Step-by-step explanation:
imagine a circle with the center at the corner (let's call it A) with the 31 degree angle. the radius is AB.
so,
x = sin(31)×AB
and
21 = cos(31)×AB
therefore,
AB = 21/cos(31) = 24.4993...
=> x = sin(31)×24.4993... = 12.62 (12.61807...)
The price of fruits per kg are given below- Watermelon Rs 18.50 Cherry Rs 72 Grapes Rs 120.60 Apples Rs 78.40 Karan bought 412 kg watermelon, 1 kg 200g cherries,250g grapes and 134 kg apples .He gave a Rs 500 note to the shopkeeper .How much money did he get back?
Answer:
[tex]X=-2.74*10^{-7}Rs[/tex]
Step-by-step explanation:
From the question we are told that:
Table for price per Kg
Watermelon Rs 18.50
Cherry Rs 72
Grapes Rs 120.60
Apples Rs 78.40
Karan Bought:
412 kg watermelon
1 kg 200g cherries
250 g grapes
134 kg apples
Generally the equation for Total Price of Fruits Bought is mathematically given by
\sum (Price Rs* Weight kg )
[tex]\sum (P* W)=(412*18.5)+(1.2*72)+(0.25*120.60+(134*78.40))[/tex]
[tex]\sum (P* W)=27374289.78[/tex]
Therefore the Amount of Money he gets back is
[tex]X=500-\sum (P* W)[/tex]
[tex]X=-2.74*10^{-7}Rs[/tex]
Therefore
He owes the shop keeper 2.74 million Rs

Correct I’ll give brainlist no links or will be reported
Answer:
0
Step-by-step explanation:
If you plug two points into the equation y2-y1/x2-x1, you will find the slope or rate of change. In this case I used the points (0,3) and (2,3). Plug them in to get 3-3/2-0. 0/2=0. Therefore, the rate of change is 0.
If this helps please mark as brainliest
Answer:
0
Step-by-step explanation:
there is no rate of change. rate of change means what is the slope or the distance the beginning and end of the line. since it is going in a straight line there is no rate of change.

the public school enrollment of a city is 13,500. Enrollment is declining at a rate of 4.5% per year. predict the enrollment in 5 years.
Answer:
The enrollment after 5 years is 10,724
Step-by-step explanation:
Generally, we can have the depreciation formula written as follows;
A = P(1 - r)^t
A is the number of enrollment in after a certain number of years t
P is the initial population which is 13,500
r is the rate of depreciation which is 4.5% = 4.5/100 = 0.045
t = 5 years
Substituting these values, we have it that;
A = 13,500(1-0.045)^5
A = 10,723.84

Write the standard form of the equation of the circle with the graph shown to the right.
Answer:
(x+5)²+(y+5)² =4
Step-by-step explanation:
the standard equation is
(x-h)²+(y-k)²=r²
where (h, k) is the center in our case ( -5, -5) and r is the radius that in our case r=2, so substitute
(x+5)²+(y+5)²=2²
Answer:
[tex](x+5)^2+(y+5)^2=4[/tex]
Step-by-step explanation:
Hi there!
Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex] where the circle is centered at (h,k) and r is the radius
1) Determine the center of the circle
On the graph, we can determine that the circle is centered at the point (-5,-5). Plug this into the equation:
[tex](x-(-5))^2+(y-(-5))^2=r^2\\(x+5)^2+(y+5)^2=r^2[/tex]
2) Determine the value of r²
In the graph, we can see that the radius of the circle is equal to 2 units. Therefore, the value of r² is 4. Plug this back into the equation:
[tex](x+5)^2+(y+5)^2=4[/tex]
I hope this helps!
