What is the difference in area between a circle with a diameter of 3 meters and a square with a side length of 3 meters? Use 3.14 for pie.

pls help me​

Answer:

89.6 meters

Step-by-step explanation:

we have to take the square root of 501.76 to find the measure of 1 side which is 22.4 which we then multiply by 4 because a square has 4 sides.

We have to find the perimeter of the park and then add 50m to that

Perimeter = 2(l+b)

                 = 2(275+200)

                 = 2* 475

                 = 950m

Therefore: Total distance covered = 950+50 = 1000 m(1km)

The students are written on the top of the fraction because of the wording students to teacher.

Step-by-step explanation:

when x >0

y=/0+7 +5

y=8

(0,8)

when x>7

y= /7+7 +5

y= 9

(7,9)

when x >-7

y = /7-7 +5

y=5

Answer:

x = 19

Step-by-step explanation:

Since DF is an angle bisector then it divides the opposite sides into segments that are proportional to the other 2 sides, that is

[tex]\frac{DE}{DG}[/tex] = [tex]\frac{EF}{GF}[/tex] , substitute values

[tex]\frac{25}{22.5}[/tex] = [tex]\frac{x-9}{9}[/tex] ( cross- multiply )

22.5(x - 9) = 225 ( divide both sides by 22.5 )

x - 9 = 10 ( add 9 to both sides )

x = 19

Answer:

56.16

Step-by-step explanation: All you do is just multiply

Answer:

$1.67

Step-by-step explanation:

Given it's $1.12 for 12 eggs, we divide 1.12 by 12 to see how much it cost for 1 egg

1.12/12 = 0.093

so 0.093 cents for 1 egg

0.093x18 eggs = 1.674 = $1.67

x = 6

Answer:

6

Step-by-step explanation:

multiple 30× .20% which equals 6. Then you will add 30 +6=36. So, Lane will do a total of 36 push-ups everyday

Answer:

-17u+5v

Step-by-step explanation:

i hate delta math im so sorry

Answer:-79v-11u

i multiplied inside the parenthesis

then got -14u-42v-7v-30+3u

then combine like terms and get -79v-11u

Answer:

the third one

Step-by-step explanation:

have a great day :)

It is C

In problem C X is still being multiplied by the other variable y, and also it is still multiplying the 7 too, The other questions do not factor in the multiplication required meaning that the only answer that could be applied would be C.

Hope this helps and have a nice day.

Answer:

This quadrilateral is a SQUARE.

When we plot these points, we realize that they are equal distance apart.

So, when a quadrilateral has sides that are equal distance apart, that quadrilateral is a square.

Let me know if this helps!

Answer:

Step-by-step explanation:

Angles formed when we turn clockwise in the given directions,

a) N to E → 90°

b). W to NE → (90° + 45°) = 135°

c). SE to NW → 180°

d). NE to N → 360° - 45° = 315°

e). W to NE → 90° + 45° = 135°

f). S to SW → 45°

g). S to SE → 360° - 45° = 315°

h). SE to SW → 180°

i). E to SW → 90° + 45° = 135°

Answer: 8 cm

Step-by-step explanation:

math

Answer:

Step-by-step explanation:

m∠R = 180° - 110° [Linear pair of angles are supplementary]

m∠R = 70°

m∠S = 45° [Vertically opposite angles]

By triangle sum theorem,

m∠P + m∠R + m∠S = 180°

m∠P + 70° + 45° = 180°

m∠P = 180 -115

        = 65°

Therefore, m∠A = m∠P = 65° [Vertically opposite angles]

By triangle sum theorem,

m∠B + m∠S + m∠T = 180°

m∠B + 45° + 65° = 180°

[m∠T = 65°. Since, ∠P and ∠T are corresponding angles]

m∠B = 180° - 110° = 70°

m∠C + m∠B = 180° [Linear pair of angles are supplementary]

m∠C = 180° - 70° = 110°

m∠D + m∠T = 180° [Linear pair of angles are supplementary]

m∠D + 65° = 180°

m∠D = 115°

Answer:

D. 39

Step-by-step explanation:

BC^2 = BA^2 + AC^2

BC^2 = 15^2 + 36^2

BC = square root (1521)

BC = 39

Answer:

D) 39

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean thm formula

Formula: a² + b² = c²

15² + 36² = c²

225 + 1296 = c²

1521 = c²

[tex]\sqrt{1521} =\sqrt{c^2}[/tex]

c = 39

Answer: (6, 5)

Step-by-step explanation: (2+4,-3-2) = (6, -5)

After reflection on x - axis, the y value changes the sign from negative to positive (to the opposite) : (6,5)

Answer:

56/19

Step-by-step explanation:

I'll approach this using Substitution. Since 3X = 2Y, we know that 1.5X = 1Y. We can plug that into the first equation, which gives us...

2X + 5(1.5X) = 8

2X + 7.5X = 8

9.5X = 8

19X = 16

X = 16/19

While this is not 'pretty', it does match up with how most of the answers are written (four of the answers involve "nineteenths"). With this value of X, we can solve for Y...

3X = 2Y

3(16/19) = 2Y

48/19 = 2Y

24/19 = Y

With the value of X and the value of Y, we can answer the question that's asked:

2X + Y = ?

2(16/19) + 24/19 =

32/19 + 24/19 =

56/19

Final Answer: 56/19

Answer:

[tex]x = - 1[/tex]

[tex]y = - 2[/tex]

Step-by-step explanation:

[tex]3x + 2y = - 7[/tex]

[tex]2x - 5y = 8[/tex]

Apply elimination method. Let multiply the bottom equation by -3/2.

[tex]2 \times - \frac{3}{2} x = - 3[/tex]

[tex] - 5 \times - \frac{3}{2} = 7.5[/tex]

[tex]8 \times - \frac{3}{2} = - 12[/tex]

Substitute new equation and add it to the top equation

[tex]3x + 2y = - 7[/tex]

[tex] - 3x + 7.5y = - 12[/tex]

[tex]9.5y = - 19[/tex]

[tex]y = - 2[/tex]

Now plug -2 for y into any equation and solve for x.

[tex]3x + 2( - 2) = - 7[/tex]

[tex]3x - 4 = - 7[/tex]

[tex]3x = - 3[/tex]

[tex]x = - 1[/tex]

Answer:A=2,4,6,8

One way of writing this in set builder notation could be:

A={x|2≤x≤8|x2∈N}

Which can be interpreted as:

The set A is the set of any  x  such that  2≤x≤8  such that half of  x  is a natural number ( N ).

There are many ways of writing sets in set builder notation. Which is why it can be a little confusing to learn (the syntax) at first. Once you understand what all these new mathematical symbols mean (i.e.  ∈ , | , N ), it becomes much easier to “read as a sentence”.

Here are a few more ways of writing the set  A=2,4,6,8  in set builder notation:

A={x|2≤x≤8|x∈2⋅N}

A={x|(x−2)(x−4)(x−6)(x−8)=0}

A={x|x=2p|p∈{1,2,3,4}}

A={x∈N|mod(x,2)=0|x≤8}
