It will be blue I say lol
Well, I’m not sure. There is no amount for each marble. So realistically you could just guess any of them.

Rolando is making buttons that are shaped like circles. Each button has an area of
62 square centimeters. Which measurement shows the circumference of each of the buttons in centimeters?
Reminder: A=π r 2
Helppppp this is due in 5 mins!!!1 :(((

Answers

Lets work backwards. π r2 = 62 cm. 62 / 3.14 = 17.75. Square root of 17.75 = 4.21. Okay, now using the radius of 4.21 we will use the formula C = 2 πr. C = 2 (3.14)(4.21) = 2 (13.22) = 26.44. So the circumference of each button is approximately 26.44 cm.

The radius= 4.21 cm

The circumference of the circle is 26.44 cm.

we have given that

Area  = 62 square centimetres.

What is the formula for the area of circle

[tex]A=\pi r^{2}[/tex]

A=62 and pi=3.14

[tex]62=3.14r^{2}[/tex]

find the value of r square divide both side by 3.14

[tex]r^2=\frac{62}{3.14}[/tex]

[tex]r^2=17.75\\[/tex]

[tex]r=4.21cm[/tex]

[tex]circumference of circle =2\pi r[/tex]

[tex]C=3.14)(4.21)\\\\C= 2 (13.22) \\\\C= 26.44.cm[/tex]

Therefore we get,

The radius= 4.21 cm

The circumference of the circle is 26.44 cm.

option 4) x = 14  y = 7

Step-by-step explanation:

We are given a side angle and a side length so we can use trigonometry to find the solution

To find x we can use sine because the given side length is opposite to the angle so,

sin(60) = [tex]\frac{7\sqrt{3} }{x}[/tex]

solve for x and you get 14 (make sure you check that your calculator is in degrees)

for either use Pythagorean theorem or remove sine by tangent.

Move Terms

7x = -42

Divide.

x = -6

good luck, i hope this helps :)

Answer:

-6

Step-by-step explanation:

4x-2+3x-7=-51

we take minus two to the other side and it becomes plus two and -51+2 is -49

4x+3x-7=-49

and we take minus seven to the other side it becomes plus seven and -49+7 iis -42

4x+3x=-42

4x+3X = 7x

7x = -42

and to remove the x we divide both sides by 7

x = -42/7

-42/7 = -6

x=-6

Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?

Answers

Answer:

Kylie is 24 years old

Step-by-step explanation:

kylie = x

Bobby=x-5

x+x-5=43

2x-5=43

2x=43+5

2x=48

X=24 years old

19

If you subtract 5 off of 43 and divide it by two you find Kylie's age. The reason you divide by two is because there are two people and it is a combined age, meaning you would divide by two.

Mrs. Jones attended a Southern Living home party. She purchased a vase which cost $34.99. The shipping charge was $3.00, and 8.25% sales tax was paid on the subtotal which included the shipping charge. How much did she pay for the vase?

Answers

Answer:

$41.12

Step-by-step explanation:

34.99 + 3 = 37.99

37.99 increase 8.25% =

37.99 × (1 + 8.25%) = 37.99 × (1 + 0.0825) = 41.124175

34.99 + $3.00 = $37.99
34.99 * 8.25/100 = $2.886675

round that number to $2.89

then add $37.99 and $2.89

the answer would be 40.88
