Answer:

the oldest elk=4(x)

second oldest elk=x+8

youngest elk=x

total spikes=32

4x+x+8+x=32

6x+8=32

6x=32-8

6x/6=24/6

x=4.

the oldest elk =4(4)=16

Step-by-step explanation:

the youngest elk=4

the second oldest elk=4+8=12

Answer: 65

Step-by-step explanation:

Answer: 65

Explanation:

Mean is all the number added together, divided by the amount of numbers in the sequence.

64+65 63+ 66+60+65+66+68+69+66+63=715

715÷11=65

Answer:

There are 32 marbles in the bag, and 1/4 of them are blue, so there are 32 * 1/4 = 8 blue marbles in the bag.

When Ed draws 4 marbles out of the bag with replacement, the probability of getting a blue marble on any given draw is 1/4.

The number of blue marbles Ed is expected to draw can be found by multiplying the probability of drawing a blue marble on each draw (1/4) by the number of draws (4):

Expected number of blue marbles = (1/4) * 4 = 1

Therefore, Ed is expected to draw 1 blue marble out of the 4 marbles drawn.

1) 1

Reasoning:

There are 4 different colors of marbles and 32 total marbles. 32/4 is 8, so there will be 8 of each at the start.

Because Ed picks 4 marbles, and there are 4 colors, we will divide 4 by 4 (4/4) and get 1.

Answer:

a) If the radius of a circle is increased 2 times, the length of the circle (circumference) will increase by a factor of 2π or approximately 6.28 times. This is because the formula for the circumference of a circle is C = 2πr, where r is the radius. If the radius is doubled, then the circumference will also be doubled.

b) If the radius of a circle is decreased 3 times, the length of the circle (circumference) will decrease by a factor of 6π or approximately 18.85 times. This is because the formula for the circumference of a circle is C = 2πr, where r is the radius. If the radius is divided by 3, then the circumference will also be divided by 3 and multiplied by 2π.

c) If the diameter of a circle is increased 6 times, the length of the circle (circumference) will increase by a factor of 6π or approximately 18.85 times. This is because the formula for the circumference of a circle is C = πd, where d is the diameter. If the diameter is multiplied by 6, then the circumference will also be multiplied by 6π

Step-by-step explanation:

pls Mark me As a brainlist

a) length of the circle increased by 2 times.

b) length of the circle decreased by 3 times.

c) length of the circle increased by 6 times.

Length of a circle that is the circumference of the circle is given by the formula = 2πr ( let's say C)

a) Given that the radius of the circle is increased by two times.

R = 2r

Required length of the circle = 2πR = 2π(2r) = 2×2πr = 2C

Hence, the length of the circle will be increased by 2 times.

b) Given that the radius is decreased by 3 times.

R= r/3

Required length of the circle =  2πR = 2π(r/3) = (2πr)/3 = C/3

Hence, the length of circle will be decreased by 3 times.

c) Given that the diameter of the circle is increased by 6 times.

D = 6d = 6×2r = 12r

Required length of the circle = πD= π×12r = 6(2πr) = 6C

Hence, the required length of circle will be increased by 6 times.

Step-by-step explanation:

The cost that will maximize the demand, considering the quadratic function, is given as follows:

$3.

The quadratic function representing the demand is given as follows:

y = -10x² + 60x + 180.

The vertex of a quadratic function is the point on the graph where the function reaches its maximum or minimum value. For a quadratic function in standard form y = ax² + bx + c, the x-coordinate of the vertex is given by:

x = -b / (2a)

The coefficients of the quadratic function in this problem are given as follows:

a = -10, b = 60.

The x-coordinate is the price that maximizes the demand, hence it is obtained as follows:

x = -60/(2 x (-20))

x = 3.

In the given triangle, the measure of angle C is 32°

From the question, we are to determine the value of angle C.

Let half of ∠IAB = a

and half of ∠IBA = b

Then,

a + b + 106° = 180° (Sum of angles in a triangle)

a + b = 74°

Also,

2a + 2b + ∠C = 180° (Sum of angles in a triangle)

2(a + b) + ∠C = 180°

2(74°) + ∠C = 180°

148° + ∠C = 180°

Subtract 148° from both sides

148° - 148° + ∠C = 180° - 148°

∠C = 32°

Hence, the measure of C is 32°

Just studied Loci in school recently

The solution is, choice B) [tex]y=5x[/tex] represent a proportional relationship.

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y\div x = k[/tex]  or [tex]y = kx[/tex]

here, we have,

we know that,

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

so, we get,

choice A) [tex]y=30x[/tex]

Is a linear equation that passes through the origin

therefore,

The case A) represent a proportional relationship

choice B) [tex]y=5x[/tex]

Is a linear equation that passes through the origin

therefore

The case B) represent a proportional relationship

choice C) [tex]y =6x[/tex]

Is a linear equation but not passes through the origin

therefore

The case C) does not represent a proportional relationship

choice D) [tex]y = \dfrac{1}{5}x[/tex]

Is a linear equation but not passes through the origin

therefore

The choice D) does not represent a proportional relationship

Hence, The solution is, choice B) [tex]y=5x[/tex] represent a proportional relationship.
