First let's find the dimensions of the garden    l = length  l/2 = width

perimeter = 39 = l + l/2 + l + l/2      results in l = 13    l/2 = 6.5 meters

The 'lawn' in the middle is 2+2    =  4   meters less in dimensions   or   9 x 2.5 = 22.5 m^2

1 Radian=[1 x 180] / pi =57.30....... degrees.

Some calculators will do this automatically for you....if not, then take the radian measure, divide it by 2 x pi and multiply it by 360 to get degrees .

Ooops......YOU are correct !    Thanx !

the x^8 's cancel each other and you are left with:

-20 x^7 + 105/15  =   -20 x^7 + 7

You had the right formula, just made an error multiplying 12 sets times 4 cups, you got 36 cups but it is 48 cups to 60 plates.

It is EXTREMELY unlikely you are the EXACT equal of your brother and you are NOT identical twins (or CLONES)...though it is theoretically POSSIBLE.  You DO HAVE at LEAST 50% of your genes in common and you probably are just noticing more your similarities than your differences.

27+9-3 = 33

If cups to plates is 4:5   that means  for every  5  plates there are 4 cups   60/5 = 12   sets of 'FIVE' plates

12sets x 4 cups = 36 cups       to  60 plates

Look in your Trig Textbook. It is all there in detail.

What the solution of(x+11)(x+10)=

x^2 + 21x + 110 

0                            

Oh ok

beacuse it just is

\(32 = 2(k – 34)\\ \frac{32}{2}=\frac{2(k-34)}{2}\\ 16=k-34 \\ \text{add to both sides 34: }\\ 16+34=k-34+34\\ 50=k\)

do the math, its really easy.

It is not called the "medium", but the "MEDIAN"!!:

20,000 + 5,000=25,000 / 2 =12,500.

Need a little bit more info....    3400t + 600 = ?      Need to have the '?'  to be able to solve for 't'

Lambda is wavelength.

Lambda =  Speed / Frequency   =  8 / 2  = 4 Meters

The new price is 3.40   the old price was 3.15     ...the price INCREASED .25  (25 cents)

25 cents is what percentage of 3.15?    .25 / 3.15  x 100% = 7.94 percent increase.

Hallo Guest!

What is the solution set for x²+6x−16=0?

x² + 6x − 16 = 0

p = 6

q = -16

x_1,2  = - p/2 ±√((p/2)² - q)

x_1,2  = - 6/2 ±√((6/2)² + 16)

x_1,2  = - 3 ±√(9 + 16)

x_1,2  = - 3 ±√25

x₁ = 2

x₂ = -8

Greeting asinus :- )

  !

This can be factored as (x - 2)(x + 8) = 0

The two possible solutions are x = 2 and x = -8

Perhaps something like the following:

Force of planet on explorer (i.e. weight) = G*M_planet*M_explorer/R²    G is a constant; R is essentially, the radius of the planet.  So:

W_a = G*1.5*10²¹*M_explorer/R_a²

W_e = G*6.4*1024*M_explorer/R_e²

Hence   W_a/W_e = (1.5*10²¹/6.4*10²⁴)*(R_e/R_a)²  → (1.5*10²¹/6.4*10²⁴)*10.5² 

I'll leave you to crunch the numbers.
