The area of a circle with a radius of 5 cm is 50.272 [tex]cm^2[/tex] bigger than a circle with a radius of 3 cm.

Given the following data:

Mathematically, the area of a circle is given by the formula:

[tex]Area = \pi r^2[/tex]

Where:

For circle A:

[tex]Area = 3.142 \times 5^2\\\\Area = 3.142 \times 25[/tex]

Area = 78.55 [tex]cm^2[/tex].

For circle A:

[tex]Area = 3.142 \times 3^2\\\\Area = 3.142 \times 9[/tex]

Area = 28.278 [tex]cm^2[/tex].

Now, we can calculate the difference:

Difference = [tex]78.55-28.278[/tex]

Difference = 50.272 [tex]cm^2[/tex].

Answer: Check out the graph below

The graph is a straight line through the points (0,6) and (1,8)

====================================

Explanation:

Plug in x = 0 to find that...

y = 2x+6

y = 2(0)+6

y = 0 + 6

y = 6

The point (0,6) is on the line

---------

Repeat for x = 1

y = 2x+6

y = 2(1)+6

y = 2 + 6

y = 8

The point (1,8) is also on the line

---------

Now plot the two points together on the same xy grid.

Draw a straight line through the two points. Stretch the line as far as you can in either direction. See below. I used GeoGebra to make the graph. It's a free graphing app.

Desmos is another useful free graphing tool. There are many options if you don't have a graphing calculator.

Step-by-step explanation:

i) Since,

Angles on the same side of a transversal in a parallelogram, there sum is 180° so,

<RGM + <GMA = 180°

=> <RGM = 180° - <GMA

=> <RGM = 180° - 66°

=> <RGM = 114° (Ans)

ii) Since,

Opposite angles of a diagonal as a transversal (here RM) are equal so,

<GRP = <PMA = 32°

As we have <GMA = 66° so,

=> <GMP = <GMA - <PMA

= 66° - 32°

=> <GMP = 34° (Ans)

iii) Since,

Opposite angles of a parallelogram are equal so,

<RGM = <RAM = 114°

As we have <PAM = 41° so,

=> <GAR = <RAM - <PAM

= 114° - 41°

=> <GAR = 73° (Ans)

iv) Since,

We got <PMA = 32° and <PAM = 41°, so by angle sum property of a triangle PMA,

=> <MPA = 180° - 32° - 41°

=> <MPA = 107° (Ans)

Answer:

x = 115° , y = 65° , z = 115°

Step-by-step explanation:

The figure is a parallelogram.

Consecutive angles are supplementary ( sum to 180° ) , then

x + 65° = 180 ( subtract 65° from both sides )

x = 115°

Opposite angles are congruent , then

y = 65°

z = x = 115°

[tex]x=1,\:x=4[/tex]

Step-by-step explanation:

[tex]x-2=\sqrt{x}\\\\(x-2)^2=x\\\\x^2-4x+4=x\\\\x^2-5x+4=0\\\\(x-1)(x-4)=0\\\\x=1,\:x=4[/tex]

x=1 and x=4 are real value or values of x satisfy the equation x−2=√x

Two or more expressions with an Equal sign is called as Equation.

Given,

Equation is x−2=√x

We need to find for which values of x satisfy the equation.

x−2=√x

Take square on both the sides

(x-2)²=√x²

We know the algebraic identity

(a-b)²=a²+b²-2ab

(x-2)²=√x²

x²+2²-2(2)x=x

x²+4-4x=x

x²+4-4x-x=0

x²-5x+4=0

x²-4x-x+4=0

x(x-4)-(x-4)=0

(x-1)(x-4)=0

x-1=0

x=1

x-4=0

x=4

Hence, x=1 and x=4 are real value or values of x satisfy the equation x−2=√x

Answer:

70%

Step-by-step explanation:

Total: 60

Strawberries: 18

Lemons: 42

[tex]\frac{42}{60}[/tex] = [tex]\frac{7}{10}[/tex] = 70%

The percentage of lemons in the group is equal to 70%.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that in the image there are 60 objects in total, the number of lemons is 42 and the number of strawberries is 18.

Total: 60

Strawberries: 18

Lemons: 42

The percentage of the lemons will be calculated as,

Percentage = 42 / 60

Percentage = 0.7

Percentage = 0.7 x 100 = 70%

Therefore, the percentage of lemons in the group is equal to 70%.

3.25 • 5 + 2.50 • 3 + 2 • 3 = x

16.25 + 7.50 + 6 = x

29.75 = how much they spent all-together

Answer:

Step-by-step explanation:

Number of cans of peas = x

Cost of 'x' cans of peas = x *0.85 = 0.85x

Number of cans of corn = y

Cost of 'y' cans of corn = 0.78*y = 0.78y

Number of cans of peas = number of cans of corn + 2

x = y + 2  --------------(I)

x - y = 2  ----------------(II)

Total cost = $ 6.59

0.85x + 0.78y = 6.59 -------------(III)

Substitute x = y +2 in equation (III)

0.85(y + 2) + 0.78y = 6.59

0.85y + 1.70 + 0.78y = 6.59

          0.85y + 0.78y = 6.59- 1.70

                  1.63y       = 4.89

                            y = 4.89/1.63

y = 3

Number of cans of corn = 3

Plugin y = 3 in equation (I)

x = 3 + 2

x = 5

Number of cans of peas = 5

Answer:

11, 13

Step-by-step explanation:

Let one of the odd positive integer be x , then the other odd positive integer is x+2.

Their sum of squares:

[tex]x^{2} +(x+2)^{2}[/tex]

[tex]x^{2} +(x+2)(x+2)[/tex]

[tex]x^{2} +x^{2} +4x+4[/tex]

[tex]2x^{2} +4x+4[/tex]

Given that their sum of squares = 290

[tex]2x^{2} +4x+4 =290[/tex]

[tex]2x^{2} +4x = 286[/tex]

[tex]2x^{2} +4x -286 = 0[/tex]

[tex]x^{2} +2x -143 =0[/tex]

[tex]x^{2}+13x-11x-143 =0[/tex]

[tex]x(x+13)-11(x+13)=0[/tex]

[tex](x+13)(x-11)=0[/tex]

Therefore x = 11, x=-13

We take positive value of x:

So, x =11 and (x+2)= 11+2=13

Therefore , the odd positive integers are 11 and 13

Answer:

D. 60°

Step-by-step explanation:

The interior angles of all triangles add up to 180 degrees.

There are two y's on the triangle

And one of the degree lengths is 60°, so we do:

2y + 60 = 180

Subtract 60 from both sides

2y + 60 - 60 = 180 - 60

2y = 120

Divide 2 from both sides

2y/2 = 120/2

y = 60°

Also, In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

All three sides are equal

All the three interior angles are equal to 60 degrees

The interior angles of all triangles add up to 180 degrees.

Heres a picture of an equilateral triangle

I've attached some theories related to angles have a look at it

Angle y and angle KJF are co-interior angles so they add up to 180°

132 + y = 180

y = 180 – 132

y = 48

y + z = 143 ( alternate angles )

48 + z = 143

z = 143 – 48

z = 95
