Answer: 3,130

Step-by-step explanation: 2,815 + 315 = 3,130

The population of the animal in 2006 was 2500.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

Given that, in 2007, a census counted 2815 of a certain animal. This was 315 fewer than the number counted in 2006.

So, the population of the animal in 2006 is

2815-315

= 2500

Therefore, the population of the animal in 2006 was 2500.

Answer:A positive correlation is a relationship between two variables such that their values increase or decrease together.

Step-by-step explanation:

Positive correlation is a relationship between two variables in which both variables move in tandem—that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.

Answer:

18.1 cm

Step-by-step explanation:

Consider a segment parallel to CD and passing through B.

This segment will form a right-angle triangle with A

It's length would be equal to the length of CD (the missing length)

Height of that triangle:

11 - 4 = 7

CD² = 16² - 7²

CD² = 207

CD = sqrt(207)

AC² = AD² + CD²

AC² = 11² + 207

AC² = 328

AC = 2sqrt(82)

Which is roughly 18.1 cm

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

Explanation:

C = pi*d is the formula for the circumference. We know that C = 44 approximately, so,

C = pi*d

d = C/pi

d = 44/3.14

d = 14.01 approximately

d = 14 also approximate

take half of this to get the radius

r = d/2 = 14/2 = 7

Then use this radius to find the circle's area

A = pi*r^2

A = 3.14*7^2

A = 153.86

A = 154  rounding to the nearest whole number

Answer:

Circle's radius

[tex]r=7.00\rm cm[/tex]

Circle's diameter

[tex]d=2r=2\times7=14\rm cm[/tex]

Circle's area

[tex]a=\pi \times r^2=3.14\times 7^2=154\rm cm^2[/tex]

Step-by-step explanation:

Given information:

Circle's circumference is = [tex]44\rm cm[/tex]

We know,

Circumference of circle [tex]=2\times\pi\times r[/tex]

On substitution,

[tex]2\times3.14\times r=44\rm cm[/tex]

Circle's radius

[tex]r=7.00\rm cm[/tex]

Circle's diameter

[tex]d=2r=2\times7=14\rm cm[/tex]

Circle's area

[tex]a=\pi \times r^2=3.14\times 7^2=154\rm cm^2[/tex]

Given:

Given that the angles of the kite.

The opposite angles of the kite measures (3y + 14)° and (y + 50)°

We need to determine the value of y.

Value of y:

We know the property that the opposite angles are equal.

Thus, applying the property, we have;

[tex]3y+14=y+50[/tex]

Subtracting both sides of the equation by y, we have;

[tex]2y+14=50[/tex]

Subtracting both sides of the equation by 14, we get;

[tex]2y=36[/tex]

Dividing both sides of the equation by 2, we get;

[tex]y=18[/tex]

Thus, the value of y is 18.

Answer:

Runner 1,2 and 3 ran at a average speed of 4.67 , 4 and 2.5 miles per hour respectively

Step-by-step explanation:

We can all agree that speed equals distance divided by time and we are asked to find out the average speed of this 3 people.

---Average speed of runner 1

Speed = distance / time

Since he ran 14 miles within 3 hours

S = 14/3

The average speed was 4.67 miles pet hour

---For runner 2,

Speed = distance / time

Since he ran 16 miles in 4 hours,

Average speed = 16/4

= 4 miles per hour

---For runner 3,

Speed = distance / time

Since he ran 15 miles under 6 hours,

Average speed = 15/6

= 2.5 miles per hour

Given:

∠APE and ∠EPD are congruent.

To find:

The measure of arc AC.

Solution:

Complete angle of a circle = 360°

m∠APE + m∠EPD + m∠DPC + m∠CPB + m∠BPA = 360°

m∠APE + m∠APE + 42° + 74° + 136° = 360°

2 m∠APE + 252° = 360°

Subtract 252° from both sides.

2 m∠APE + 252° - 252° = 360° - 252°

2 m∠APE = 108°

Divide by 2 on both sides.

m∠APE = 54°

Given ∠APE and ∠EPD are congruent.

m∠EPD = 54°

m∠APC = 54° + 54° + 42°

             = 150°

The measure of central angle is congruent to the measure of the intercepted arc.

m(ar AC) = m∠APC

m(ar AC) = 150°

The arc measure of AC on circle P is 150°.

Answer:

y ≈ 4.3 cm

Step-by-step explanation:

Given 2 secants from an external point to the circle.

The the product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is

3(3 + y) = 2(2 + 6 + 3) = 2(11) = 22, that is

9 + 3y = 22 ( subtract 9 from both parts )

3y = 13 ( divide both sides by 3 )

y ≈ 4. 3 cm ( to the nearest tenth )

Answer: 3.25G + 0.74F = t

Step-by-step explanation: For this problem we will write an expression to represent this situation.

Let total cost be equal to t.

3.25G + 0.74F = t

The expression above states that at $3.25 per pounds of granola and $0.74 per pounds of flour, you will find the total cost of buying both, which is t.

The total cost of buying G pounds of granola at $3.25 per pound and F pounds of flour at $0.74 per pound can be calculated using the expression (G × $3.25) + (F × $0.74).

To determine the total cost of buying G pounds of granola at $3.25 per pound and F pounds of flour at $0.74 per pound, you can use the following expression:

Total Cost = (G × $3.25) + (F × $0.74)

This expression multiplies the number of pounds of granola (G) by its price per pound and adds it to the product of the number of pounds of flour (F) and its price per pound. To find the total cost, simply substitute the values for G and F into this expression and calculate the sum.
