Jennifer earns $5.50 an hour for babysitting.edward earns 1.8 times as much for mowing lawns.explain how you can tell whose hour
algol [13]
$5.50 * 1.8 = $9.90 (Edward)

$50 / $5.50 = 9.09 rounded to make 10 hours (Jennifer)
$50 / $9.90 = 5.05 rounded to make 6 hours (Edward)
so Jennifer needs 10 hours
Edward needs 6 hours

the length of a diagonal of a square field is 220 metres find the length of a side in metres and the area of the field in hectar
andre [41]

Answer:

Step-by-step explanation:

h^2=x^2+y^2, since this is a square x=y=s so

220^2=2s^2

2s^2=48400

s^2=24200

s=24200^(1/2)m (exact)

s=155.56m (rounded to nearest hundredth of a meter)

One hectare is equal to 10000m^2

A=24200m^2(h/10000m^2)

A=2.42 hectares

What is the additive inverse of non complex 9
svet-max [94.6K]

the additive inverse of non complex 9 is -9 .

<u>Step-by-step explanation:</u>

Complex number is said to be the sum of whole numbers and imaginary numbers.The additive inverse of the any number is the changing the sign of the number. That is instead –ve sign is positive and vice versa.

Additive Inverse of Complex Numbers:

Let take the complex numbers  Z = X + iy and its inverse be Z^{-1} = a + ib

Step 1: Now add the Z and Z-1, we get

Z + Z^{-1} = (X + iy) + (a + ib) = 0

Step 2: Combine Like term, we get

(X + a) + i (y + b) = 0

Step 3: By using zero product property, we can equating as

X + a = 0 and i (y + b) = 0

X = -a and y = -b

Thus, the additive inverse of the complex numbers X + iy = -X - iy .

Now, additive inverse of 9+0i = -9-0i=-9 .

Therefore , the additive inverse of non complex 9 is -9 .
