Step-by-step explanation: took the test got it right

The required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

The area of the circle is given by the pie times square of the radius.

Area of circle = πr^2

Here,
Let the radius of the given circle be r = 5 cm
Area of the circle = πr²

Substitute the value in the above expression,
Area of the circle = π 5²
Area of the circle = 78.5cm²

Thus, the required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

192 cm²

Let us take the height be x , then its side = x + 4. Now half of base will be 12 cm .

According to Pythagoras Theorem :-

=> base² + perpendicular ² = hypontenuse ²

=> 12² + x² = (x+4)²

=> 144 + x² = x² + 16 + 8x

=> 8x = 144-16

=> 8x = 128

=> x = 128/8

=> x = 16 cm .

Hence the height of ∆ is 16 cm .So the area will be half the product of base and altitude.

= 1/2 * 16 cm * 24cm .

= 192 cm²

Step-by-step explanation:

1)divide by 2

2.) every yellow marble is 1 and there is 5 marbles for each yelllow marble

The ratio of boys to girls in the Grade 6 math class is =

8 : 9.

For every yellow marble, there are five blue marbles.

To find the ratio of a given two quantities how many times one quantity is greater or smaller than the other.

To find the ratio of boys to girls in Grade 6 math class simplify by dividing through with two.

Therefore, 16/18 = 8/ 9, that is 8 boys is to 9 girls.

The 5:1 ratio of blue to yellow marbles means for every yellow marble, there are five blue marbles.

Step-by-step explanation:

Answer:

-8 + 12n

Step-by-step explanation:

First term = a = 4

Common difference = d = second term - first term

                                 = 16 - 4

                                 = 12

Nth term = a + (n -1) *d

              = 4 + (n - 1)*12

              = 4 + n*12 - 1*12

               = 4 + 12n - 12

               = 4 - 12 + 12n

                = -8 + 12n

La respuesta es la opción A

Answer:

2x=50

Step-by-step explanation:

Hi there,

Your question is "twice a number (x) is fifty"

Recall how a number is represented by x.

Twice a number would be represented as 2x.

Therefore, to represent that twice a number is equal to 50, that would result in the expression: [tex]2x=50[/tex]

If you're looking to solve this equation, it's often best to think about the "reverse" of the current equation.

Notice how 2 is multiplying the x.

To isolate x, divide that side by 2.

However, recall that whatever is done to one side of an equation must also be done to the other side of the equation. Therefore, you will need to divide both sides by 2.

[tex]2x=50[/tex]

[tex]\frac{2x}{2} = \frac{50}{2}[/tex]

[tex]x=25[/tex]

Equation: [tex]2x=50[/tex]

Solving for x: 25

Hope that helps!
