10

Explanation: Explanation:

This is a ratio question in disguise.

By parts of the question:

"When y varies directly with x"

→

y

x

"

"if y=8 when x=4"

→

.

.

y

x

=

8

4

"how do you find y when x=5"

→

y

x

=

8

4

=

y

5

so

y

=

8

×

5

4

=

10

This is the same thing as using 'k' in the other solution

Which gives the area of a rhombus with sides of length 10 in. and longer
cupoosta [38]

Answer:

B

Explanation:

Draw the Rhombus

Draw a rhombus.

At the midpoint of the given diagonal, draw a line to the enclosed angle of two of the sides.

The diagonals meet at 90 degrees.

You can use the Pythagorean Theorem to get the third side.

c^2 = a^2 + b^2

c = 10                  length of 1 side

b = 8                   This is 1/2 of 16. They diagonals meet at their midpoints

a = ?

10^2 = 8^2 + a^2

100 = 64 + a^2

a^2 = 36

a = 6

The area of one right triangle = 6*8/2 = 24

The area of all 4 right triangles = 96

Last month, he sold 50 chickens and 30 ducks for \$550
olasank [31]

Answer:

Answer:

Cost of one (chicken) =  $ 8

Cost of one (duck)  = $ 5

Explanation: heyy there :)

Let c be (chickens) and d be (ducks)

Given :  

50 �+ 30 � = $ 550

Dividing both sides by 10,

5 + 3 = 55 Eqn (1)

44 + 36 = $ 532

11 + 9 = 133 Eqn (2)

Multiply Eqn (1) by 3 to eliminate y term when subtraing Eqn (1) from (2).

Then a Eqn (1) becomes, 15 + 9 = 165 Eqn (3)

Subtracting Eqn (2) from (3),

(15 - 11) = (165 - 133)

4 = 32 or = $ 8.

Substituting value of in Eqn (1),

(5 * 8) + 3 = 55

3 = 55 - 40 = 15

= 15 / 3 = $ 5

The idea that human behavior should be studied through systematic observation and experimentation is known as _______________.
AURORKA [14]

Answer:

Empiricism

Explanation:

Empiricism is human behavior based on observation and experimentation. It is a way of acquiring knowledge through experience. Many examples lead people and their senses to believe in something.

Empiricism is relying on observations, even though sometimes the senses can deceive. As the empiricism is a part of science, every observation is based on structures. People learn about the world through planning, recording, and analyzing observations about it.

kompoz [17]

Answer:

I think this is the right answer. Not 100% sure based on the given question and quantity of possible answers.

Jung and Freud were friends and therefore agreed on many similar opinions such as  dreams are the window to people's unconscious minds and the psychology of people in general however, their disagreeing opinions on the fundamentals and derivatives of dreams, the (un)conscious mind, sex and sexuality, and para-phycology tore their friendship apart.

A good website for more in-depth differences and similarities is harleytherapy.co.uk (I'm not sure if I'm allowed to post links on here, that's why there isn't a link private message me for a direct link.)
