Can you please help thanks

Answer:

The area of the shaded region is 6.88 cm ² (3.44+3.44)

Step-by-step explanation:

Area of the shaded part = Area of the square - Area of the two semi circles + overlapped yellow area

Area of the square = 4² = 16

r = 4/2 = r=2cm

Area of semicircle = πr²/2

Area of the semicircle =  π(2) ²/2

Area of one semicircle = 6.28 cm²

Area of two semi-circles = 2 * 6.28 cm²

Area of two semi-circles = 12.56 cm²

Area of the shaded region    = Area of a square - Area of two semicircles (plus overlapped area)

Area of the shaded region (minus overlapped area) = 16  cm² - 12.56  cm²

Area of the shaded region (minus overlapped area) =  3.44

Now we need to add the overlapping area of the 2 semicircles

Area overlapped yellow = 1

The other yellow area =2

White parts= S

The area of  2  semicircles  with side length 2 (half of 4)   is the same.

The area of the big quarter circle is π*2r*2r/4 = π*r², because its radius is twice as big as the small circles.

S =  area of each white  as  the area of the semicircles is:

π*r²/2 = I + S

So, the area of 1  = π*r²/2 - S. The area of the big quarter circle is:

π*r² = 1 + 2+ S + S

Subtract the area of a semicircle circle, and we have

π*r² - π*r²/2 = 1 + 2 + S + S - 1 - S

π*r²/2 = 2 + S

so 2 = π*r²/2 - S.

That means that the area of 1  and 2  are the same

Answer:

The first answer is 3) 9(3r-4) and 27r-36

The second answer is 2) Y squared - 36/6

The third answer is 1) 300

Step-by-step explanation:

First answer :

Equivalent expressions are expressions that work the same even though they look different.

9(3r-4) is equal to 27r-36.

9 x 3r = 27r

9 x 4 = 36

27r-36

Second answer :

"The square of y decreased by quotient of 36 and 6" Explains the answer which is Y squared - 36/6

Third answer :

The formula you want to follow is: 2(LW+WH+HL)

2(LW+WH+HL) = 2(12x9+9x2+2x12)

2(12x9+9x2+2x12) = 300

Answer:

Paul

Step-by-step explanation:

Paul earn more than monica. Though he is getting less interest but because of his higher initial amount he is getting more return.

Computing the return of both

Monica return is  100*3.4%= $3.4 in a year

Paul return is 200*%2.2=  $4.4 in a year.

Answer:

(-8,-5)

Step-by-step explanation:

When you go from quadrant I, where both the X and Y values are positive and rotate 180 degrees you end up in quadrant III, where both X and Y values are negative! Hope this helps :)

Answer:

(-8,-5)

Step-by-step explanation:

A counterclockwise rotation of 180 degrees about the origin changes the original coordinate for ex; (1,-2) to (-1,2)

So, with a counterclockwise rotation of 180 degrees (8,5)  to (-8,5)

Answer:

y = 4 / x = 2

Step-by-step explanation:

Insert x equation for variable x

y = 2(-y+6)

simplify

y= -2y + 12

add 2y to both sides

3y= 12

divide both sides by 3

y = 4

Insert 4 as y in y =2x

4=2x

divide both sides by 2

x=2

I'd say that they are all equivalent because when you divided all of them it equals each other.

2:6 = 1/3

3:9 = 1/3

4:12 = 1/3

Answer:

Perimeter= 7.71 ft

Step-by-step explanation: Perimeter= radius(π +2)

      The diameter of the circle is 3ft

therefore, radius is 1/2 of diameter (i.e 3/2) =1.5 ft

π=3.14

Therefore, Perimeter= 1.5(3.14 + 2)

                   Perimeter=7.71 ft

In the 2 x 2 array, the sum of all squares is 18 x 17 = 306.

The number in the 4 sections are 100, 80, 70, and 56.

A 2 x 2 array that shows the problem 18 x 17.

2 x 2 array has four blockers or magic quadrants, the matrix diagram is a simple square divided into four equal quadrants.

18 = 10 +8

17 = 10 +7

18 x 17 = 306

In the 2 x 2 array : 100+80+70+56 = 18 x 17 = 306

Therefore, In the 2 x 2 array, the sum of all squares is 18 x 17 = 306.

[MA]:

$28

The explanation:

The 5 coffees are 40% off.

5 x 4 = 20

40% - $20 = 12

4 x 4 = 16

12 + 16 = 28

Answer:

It would cost n people $nd to play Decimal Decisions and $nr to play Ratio Rage. So, it would cost n people $nd + $nr= $2n(d + r).

d= Decimal Decisions and r= Ratio Rage

You didn't give a price for either game, so I just did variables in place of actual cost. Hope this helps!

Step-by-step explanation:

Answer:

(-9,0) It would stay the same.

Step-by-step explanation:

Reflection over the X-axis means you keep the 'x' point the same and multiply the 'y' point by -1 (change the sign).

-9 stays the same

[tex]0 * -1 = 0[/tex]

(-9,0)

Answer:

y=2x

Step-by-step explanation:

Every y value is double the x value on top.

y=6:
6 = 3 × ?

? = 2

y=10:

10 = 5 × ?

? = 2

And so on....

So the equation that represents this data is :

y=2x

Answer:

[tex]\dfrac{3}{4} \ * \ \dfrac{1}{2}[/tex]

Explanation:

Full batch requires [tex]\sf\frac{3}{4}[/tex] cups of sugar.

she is making half the batch so we shall half it.

note: we can write x ÷ 2, as  [tex]* \ \sf\dfrac{x}{2}[/tex]

She is making half batch only, So she will require the half amount of sugar which means we need to multiply 1/2 and 3/4

[tex] \frac{1}{2} \div \frac{3}{4} [/tex]

[tex] \frac{1×3}{2×4} [/tex]

[tex] \frac{3}{8} [/tex]

She will require 0.375 cup of sugar for making 1/2 batch...~

Answer:

KL = 11.9 approximately

Step-by-step explanation:

It is stated that the two quadrilaterals are similar

if they are similar then their side lengths are proportional

So we can use that to find KL

JG/NK = GH/KL

(52.5)/17=37/KL cross multiply expressions

52.5*KL = 629 divide both sides by 52.5

KL = 11.9 approximately

Answer:

7√5

Step-by-step explanation:

Begin calculating the factors of 245, starting with 1.
