Answer:

4 horses and 8 ducks.

Step-by-step explanation:

Let the number of ducks be d and the number of horses be h.

d + h = 12

Now ducks have 2 feet and horses have 4 so:

2d + 4h = 32

Multiply the first equation by 2

2d + 2h = 24

Subtract this equation from the second equation:

4h - 2h = 32 - 24

2h = 8

h = 4.

So there were 4 horses and 12 - 4 = 8 ducks.

Select all the expressions that could represent the volume of a box, which is a third degree polynomial in variables x and y.
Citrus2011 [14]

Answer:

A and D

Step-by-step explanation:

Third degree polynomials refers to polynomials that has 3 as the greatest power of the variable.

A. 3 x y − 3 x y^2

Degree = 1 + 2 = 3

This option is correct

B 2y - xy^3 + 7

Degree = 1 + 3 = 4

This option is wrong

C. 3x^3y^2 -3x^2y + 10y^2 - 10y

Degree = 3 + 2 = 5

This option is wrong

D. 3x^2y+5xy

Degree = 2 + 1 = 3

This option is correct

E. 3y^3 + 3x^3 y^4

Degree = 3 + 4 = 7

This option is wrong

A kite is flying 70 feet above the ground and is attached to a string tied to a stake on the ground. The angle of elevation form
frozen [14]
If you draw a diagram of this, your given values of the resulting triangle give you the sides opposite and adjacent of the angle. The formula that uses these sides is tangent.

The tangent of an angle is equal to the ratio of the opposite side over the other non-hypotenuse side (adjacent).

Therefore;

tan(40)=70/x
0.83909963117=70/x
0.83909963117x=70
x=70/0.83909963117
x=83.4227514823

Where x is the length of the string in feet.

Write an equation for each question, please! (t = years after 1960)
VashaNatasha [74]

Answer:

<u>1)</u> y = - 0.54(25)

<u>2)</u> 0.4 = 98 - 0.54t

<u>3)</u> 0.6 = 2 + 0.54t

<u>4)</u> 98 - 0.54t = 2(2 + 0.54t)

(you asked for equations, so I <em>think </em>these are the equations you are looking for!)

Step-by-step explanation:

1)

<em>(given)</em> y = 98 - 0.54t

<em>(plugging in years after 1960)</em> y = - 0.54(25)

2)

<em>(given)</em> y = 98 - 0.54t

(changing percent to decimal) 40% = 0.4

(plugging in percentage) 0.4 = 98 - 0.54t

3)

<em>(given)</em> y = 2 + 0.54t

(changing percent to decimal) 60% = 0.6

(plugging in percentage) 0.6 = 2 + 0.54t

4)

<em>(given)</em>

<em>(male)</em> y = 98 - 0.54t

<em>(female)</em> y = 2 + 0.54t

<em>(setting up the equation so male is 2 times the percent of female)</em>

98 - 0.54t = 2(2 + 0.54t)
