how many birds fly south every year?

Answer: First one, 25x^2y^22

Step-by-step explanation:

if you multiply y^5*2 you get y^10 and x^2

that makes x^2y^10

then, if you multiply y^3*4 you get y^12

so you have to add the y s that makes x^2y^22

Answer:

2/8

Step-by-step explanation:

Answer:

h(4) = 3

f-1(-3) = - 1

Step-by-step explanation:

One

h(x) = 2x - 5

h(4) = 2*4 - 5

h(4) = 8 - 5

h(4) = 3

Two

Let y = f(x)

y = 5x + 2           Interchange x and y

x = 5y + 2           Subtract 2 from both sides

(x - 2) = 5y          Divide by 5

(x - 2)/5 =  y

but y = f'(x)

so f(x) = (x - 2)/5

f-1(-3) = (-3 - 2) / 5

f-1(-3) = -5/5

f-1(-3) = - 1

Answer:

I would say about 67 minutes

Answer:

14

Step-by-step explanation:

A number that is exactly halfway between 1 and 27 is the middle number

In other words, we want to find the median between 1 and 27

Median = (x + y) / 2

Let

x = 1

y = 27

Median = (x + y) / 2

= (1 + 27) / 2

= 28/2

= 14

Therefore, the number between 1 and 27 is 14

Answer:

y = 2

Step-by-step explanation:

(4x+9y)-(4x+5y) = 14-6

4x-4x+9y-5y = 8

4y = 8

y = 2

Answer:

The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50

Step-by-step explanation:

Let,

x be the price per pound of walnuts

y be the price per pound of chocolate chips

According to given statement,

4x+8y=25     Eqn 1

2x+3y=10      Eqn 2

Multiplying Eqn 2 by 2

2(2x+3y=10)

4x+6y=20    Eqn 3

Subtracting Eqn 3 from Eqn 1

(4x+8y)-(4x+6y)=25-20

4x+8y-4x-6y=5

2y=5

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{5}{2}\\y=2.50[/tex]

Putting y=2.50 in Eqn 2

2x+3(2.50)=10

2x+7.50=10

2x=10-7.50

2x=2.50

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{2.50}{2}\\x=1.25[/tex]

Hence,

The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50

Answer:

The numerator is the number on top of the bottom number (denominator)

Answer:

410 minutes

Step-by-step explanation:

Given that:

Time for which Jesse practices trumpet in the first week = 165 minutes

Time for which Jesse practices trumpet in the second week = 245 minutes

To find:

The total amount of time rounded to the nearest 10 minutes.

Solution:

To find the total amount of time for which Jesse practices, we need to add the time taken for practice in the first week and the time taken for practice in the second week.

Therefore, total time taken = 165 + 245 = 410 minutes

It is already rounded off to the nearest 10 minutes.

Therefore, the answer is:

Total amount of time for which Jesse practices = 410 minutes

Answer:

Option C. [tex]98^{\circ}[/tex]

Step-by-step explanation:

[tex]\angle DAB + \angle BAC = 180[/tex] (the two angles sum to the angle of a straight line: [tex]180^{\circ}[/tex])

[tex]122+\angle BAC = 180[/tex]

[tex]\angle BAC = 180-122[/tex]

[tex]=58^{\circ}[/tex]

[tex]24+58+x = 180[/tex] (sum of interior angles of triangle is [tex]180^{\circ}[/tex])

[tex]82+x=180[/tex]

[tex]x=98^{\circ}[/tex]

∴ Option C is correct.

Answer:

[tex]\frac{1}{cos^2a }= tan^2 a[/tex]

Step-by-step explanation:

Explanation:-

Given   sin²a + cos²a = 1  

and

              [tex]\frac{1}{cos^{2} a} \\= \frac{sin^2a+cos^2a}{cos^2a} \\ \\\\ = \frac{sin^2a}{cos^2a} +\frac{cos^2a}{cos^2a}[/tex]

= tan²a + 1



Answer:

The slope is 2/1 and the y-intercept is -6.

Step-by-step explanation:

With the y=mx+b formula, m is the slope and b is the intercept.

Answer: -6

But not too sure tho make sure of it

Answer:

b) y = -2/3 + 1

Step-by-step explanation:

The format for the equation is y = mx + b

(m is the slope, and b is the y intercept)

Slope is rise over run (the units the line moves up and the units the line moves to the right)

In this case, the slope is: -2/3 because it goes down 2 and to the right 3.

The y intercept is 1.

This makes our equation:

y = -2/3 + 1

Answer:

B.9

Step-by-step explanation:

What I did is I used ratio.

20:12

15:X

Cross multiply:15x12

Answer:180

The answer you get divided by 20.

180/20=9.

Answer:

B

Step-by-step explanation:

Given y varies directly as x, then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition when x = 20, y = 12, then

12 = 20k ( divide both sides by 20 )

k = [tex]\frac{12}{20}[/tex] = [tex]\frac{3}{5}[/tex]

y = [tex]\frac{3}{5}[/tex] x ← equation of variation

When x = 15, then

y = [tex]\frac{3}{5}[/tex] × 15 = 9

Answer:

see below

Step-by-step explanation:

we know that

[tex]\angle 1 =\angle 2[/tex]

and that

[tex]\angle 1 +\angle 2 = 180[/tex]

so we substitute angle 2 by angle 1

[tex]\angle 1 +\angle 1 = 180\\\\2\angle 1=180\\\\\angle 1 = 90[/tex]

so there we have it

[tex]\angle 1 = 90 =\angle 2[/tex]

Answer:

Step-by-step explanation:

Supplementary angles are two or more angles whose the addition of their measures add up to [tex]180^{o}[/tex].

Given: <1 and <2.

<1 + <2 =  [tex]180^{o}[/tex] (supplementary angles)

If <1 ≅ <2 (congruent property), then we have;

<1 + <1 =  [tex]180^{o}[/tex]

2<1 =  [tex]180^{o}[/tex]

<1 = [tex]\frac{180}{2}[/tex]

   = [tex]90^{o}[/tex]

<1 = [tex]90^{o}[/tex]

So that since <1 and <2 are congruent, then;

<1 ≅ <2 ≅ [tex]90^{o}[/tex]

Therefore if <1 and <2 are supplementary and congruent, then they are right angles.
