I believe it is C as it would have 2 different marbles each draw and I think there is only one marble for each color so it cant be d and b is possible but you can't only draw two colors if there is still two more and A is as if u are drawing one marble each time

the answer is c

Find the area of a circle with a diameter of six. Either enter an exact answer in terms of pie or use 3.14 for pie and enter you
miss Akunina [59]

Answer:

The area of the circle is 28.26

The area of the circle in terms of pi is 9π

Step-by-step explanation:

radius = half of diameter

d = 6

r = 6/2 = 3

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 3

π = pi

a = π * r²

we replace with the known values

a = π * (3)²

a = π * 9

a = 9π

The area of the circle in terms of pi is 9π

9 * 3.14 = 28.26

The area of the circle is 28.26

Over the last three evenings, Donna received a total of 129 phone calls at the call center. The third evening, she received 3 ti
lakkis [162]

Answer:

Number of calls received in 1st evening = 24

Number of calls received in 2nd evening = 33

Number of calls received in 3rd evening = 72

Step-by-step explanation:

Let

number of calls received in first evening be "x"

number of calls received in 2nd evening be "y"

number of calls received in 3rd evening be "z"

Total, in 3 evenings, we have 129 phone calls, so we can write:

x + y + z = 129

3rd evening, 3 times as first evening. We can write:

z = 3x

2nd evening, 9 MORE THAN FIRST. So we can write:

y = 9 + x

Now we replace 2nd and 3rd equation in 1st equation to get:

x + y + z = 129

x + 9 + x + 3x = 129

Now, first, we solve for x:

x + 9 + x + 3x = 129\\5x+9=129\\5x=120\\x=24

Solving for y:

y = 9 + x

y = 9 + 24

y = 33

Solving for z:

z = 3x

z = 3(24)

z = 72

Thus,

Number of calls received in 1st evening = 24

Number of calls received in 2nd evening = 33

Number of calls received in 3rd evening = 72

Find the vertex of this parabola:<br> y = -x2 - 4x - 2
VikaD [51]
<h3>Hello!</h3>

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

In order to find the vertex of a parabola, we use the following formula:

\bold{\displaystyle\frac{-b}{2a} }}

Remember, a parabola looks like so:

\tt{y=ax^2+bx+c}

Now we know what a and b stand for.

In this case, b is -4, and a is -1:

\hookrightarrow\sf{\displaystyle\frac{-(-4)}{2(-1)}

Simplify:

\hookrightarrow\sf{\displaystyle\frac{4}{-2} }}

Divide:

\hookrightarrow\sf{-2}

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