The major thing that differentiate microeconomics from macroeconomics is the object of study. Microeconomics refers to the study of economics at individual, group or business level while macroeconomics involves the study of economics on the national scale, that is the study of the economy of a nation. The economics of a nation is the combination of all the individuals, businesses, households, etc in a country.

Bill bought 38 1/2 feet of wire fencing to put around his blueberry plants. He cut the wire into several pieces, each one measur

Nadya [2.5K]

Answer: 7

Step-by-step explanation:

You are given that Bill bought 38 1/2 feet of wire. Convert the mixed fraction into improper fraction.

The length L1 = 77/2

You are given that he cut the wire into several pieces, each one measuring 5 1/2 feet. Convert it too to improper fraction.

The length L2 = 11/2

To know how many number of pieces of wire he have after making the cuts, divide length L1 by length L2. That is,

L1/L2 = 77/2 ÷ 11/2

Change the division to multiplication by reciprocating 11/2 to 2/11

77/2 × 2/11 = 77/11 = 7

Therefore, he had 7 pieces of wires after making the cuts.

Can a triangle have sides of lengths 9,17,15? Show why or why not.

Elden [556K]

Answer:

A triangle has 3 sides: a, b, c satisfying inequalities below:

=> a + b > c > |a - b|

=> b + c > a > |b - c|

=> c + a > b > |c - a|

9, 15, 17 satisfy the inequalities above (you can check it easily).

Hope this helps!

John who is 5 ft tall is standing 20 feet away from a tree, and you measure the angle of elevation to be 38∘. How tall is the tr

fenix001 [56]

Answer:

The tree is 20.6 ft tall.

Step-by-step explanation:

Please check the attached graph.

From the diagram, it is clear that John is 5 ft tall is standing 20 feet away from a tree, making an angle of elevation to be 38⁰.

The diagram makes a right-angled triangle.

Given the angle = Ф = 38⁰

Adjacent = a = 5 ft

Opposite = b = 20 ft

Hypotenuse = Tree length = c ?

Pythagorean Theorem:

For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:

$\:c=\sqrt{a^2+b^2}$

substituting a=5, b=20

$c=\sqrt{5^2+20^2}$

$c=5\sqrt{17}$

$c=20.6$ ft

Thus, the tree is 20.6 ft tall.

Answer:

Coordinates of point P is $(-14,3)$ .

Step-by-step explanation:

Given that mid point of line segment $\overline {PQ}$ is at M(-9, 8.5).

Q is at (-4, 14).

Let coordinate of P be $(x,y)$ .

Using the ratio, we can say the following:

The coordinates of mid point $(X,Y)$ of a line with endpoints $(x_1, y_1)$ and $(x_2, y_2)$ is given as:

$X=\dfrac{(x_1+ x_2)}{2}$

$Y=\dfrac{(y_1+ y_2)}{2}$

Using the formula for above given dimensions:

$-9 =\dfrac{x+(-4)}{2}\\\Rightarrow x = -18+4 = -14$

$8.5=\dfrac{(14+ y)}{2}\\\Rightarrow y = 17-14 =3$

So, the coordinates of point P are $(-14,3)$ .

Answer: x>-1

Step-by-step explanation:

Dotted line on the axis is covering y infinitely, so theres an inequality on x, and the line is at -1, so x should be > - 1
