Answer:

Decreased

Step-by-step explanation:

-The rate of growth in food prices can be calculated using the compound interest formula as:

A=P(1+i)^t\\\\1402=657(1+i)^{10}\\\\(1+i)=(\frac{1402}{657})^{0.1}\\\\1+i=1.07874\\\\i=0.07874

We use the calculated growth rate in food prices to find the potential future value of a 90's income:

A=P(1+i)^n\\\\=1518(1.07874)^{10}\\\\=3239.21

#Compare this calculated value to the stated value:

3239.21>2632

Hence, the real value of income has decreased since it's less than it's future value over the 10-year period.

Solve for x: x/2x+3 + 2x+3/x = 184/65​
Marat540 [252]

Answer:

x/2x+3 + 2x +3/x = 184 /65

x(2x + 3)–1 + (2x+3)x-1 = 184/65

(2x + 3)x / (2x +3)x = 184/65

2x² + 3x / 2x² + 3x = 184/65

1x= 184/64

x = 184/64

Consider the 1-to10^19 scale on which the disk of the Milky Way Galaxy fits on a football field. On this scale, how far is it fr
bezimeni [28]

Beautiful !  What a great exercise !  I won't even check to verify
that 1:10⁻¹⁹ is an appropriate scale to map the Milky Way onto a
football field.  I'll just accept it and go from there.

(4.4 light years) x (10⁻¹⁹) = (2.5848 x 10¹³ miles) x (10⁻¹⁹)

                                       =  2.5848 x 10⁻⁶ mile

                                       =    0.164 inch .

(1,391,400 kilometers) x (10⁻¹⁹) = 1.3914 x 10⁻¹⁰ meter


Research Conclusions:

If the Milky Way shrinks to fit on a football field, then

-- Alpha Centauri is  0.164 inch from us.

-- The sun's diameter is about 1.39 times that of a Hydrogen atom. 

Playing with this same fun concept a little more:

-- The Earth is sailing around in its orbit, once a year,
    about 0.000015 millimeter from the sun. 

-- It takes light almost 27 years to travel 1 inch !

3x-11=x+23
-x -x
2x-11=23
+11 +11
2x=34
x=17

3(17)-11 17+23
=40 =40

explanation ;
you would equal them because they are congruent . & you substitute x for 17 in each equation to find out the degrees of both of the angles :)
