1/(-3/8) = -8/3 = answer

The multiplicative inverse of a number x is a number y such that their product xy is 1.

So, we want a number such that

$-\dfrac{3}{8}\cdot x = 1$

Multply both sides by 8:

$-3x=8$

Divide both sides by 3:

$-x=\dfrac{8}{3}$

Change sign to both sides:

$x=-\dfrac{8}{3}$

SOVA2 [1]

The question is:

In each of the following examples, a consumer purchases just two goods: x and y. Based on the information in each of the following parts, sketch a plausible set of indifference curves (that is, draw at least two curves on a set of labeled axes, and indicate the direction of higher utility). Also, writedown a utility function u(x, y) consistent with your graph. Note that although all these preferences should be assumed to be complete and transitive (as required for utility representation), not all will be monotone.

(a) Jessica enjoys bagels x and coffee y, and consuming more of one makes consuming the other more enjoyable.

(b) Plamen loves mocha swirl ice cream x, but he hates mushrooms y.

(d) Edward always buys three white tank tops x for every pair of jeans y.

(e) Nancy likes both peanut butter x and jelly y, and always gets the same additional satisfaction from an ounce of peanut butter as she does from two ounces of jelly.

Step-by-step explanation:

The utility functions consistent with the graphs are:

(a) u(x, y) = xy

(b) u(x, y) = x - y

(d) u(x, y) = min(x, 3y)

See attachments for the graphs.

If 1 cm represents 30 km on a map and colorado is shown by a 20cm by 15 cm rectangle on the map, what is the approximate actual

zubka84 [21]

Answer:

20*30km = 600km

15*30km = 450km

600km * 450km = 270000 km^2

Step-by-step explanation:

assuming 1cm --- 30km causes that 2cm --- 60km, 3cm --- 90km, 4cm --- 120km etc. Notice that number of km's is 30 times greater than the number of cm's on a map

using this logic, you calculate both real dimensions of Colorado by multiplying 20*30 = 600 km and 15*30 = 450km

Then we use a formula of an area of a rectangle $A=a\cdot b$ assuming $a=600km, \ b=450km$ and get $A=600\cdot 450=270000km^2$ which is an actual area of Colorado

Find the area of the circle to the nearest whole number, if necessary!

astra-53 [7]

Answer:

The circle has an area of about 1385 square mm.

Step-by-step explanation:

Let's recall that circles have an area that can be found with the following formula:

$A=\pi r^{2}$

where r is the radius of the circle.

Now, focus your eyes on the circle. We are shown that the diameter of this circle is 42 mm, but we only want the radius. Since the radius is half the diameter, the radius is 21 mm. Now, we can solve for the area of the circle.

$A=\pi (21)^2\\A=441\pi \\A=1385.44236...$

So, to the nearest whole number, the area of the circle is 1385 square mm.
