This is not possible if both numbers are whole numbers.

The larger number would be

(20+15)/2 = 17.5

The smaller number would be

(20-15)/2=2.5

So they cannot be whole numbers.

Charra [1.4K]

Answer:

He have <u>0.96 acres</u> of early corn.

Step-by-step explanation:

Given:

Toms garden is 8 acres. Two fifths is corn.

Of that, three tenths is early corn and one tenth is late corn.

Now, to find the acres of early corn.

Total garden = 8 acres.

Total Corn in garden = \frac{2}{5}\ of\ 8=\frac{2}{5} \times 8=\frac{16}{5} acres.

<em>As, given of the total corn in garden, three tenths is early corn.</em>

Now, to get the early corn he have:

= \frac{3}{10} of \frac{16}{5}

= \frac{3}{10} \times \frac{16}{5}

= \frac{48}{50}

= 0.96\ acres.

Therefore, he have 0.96 acres of early corn.

\sqrt{(2 \times 2)}  \times 3 \times 5

3) Rewrite each pair in exponent form.

\sqrt{ {2}^{2} \times 3 \times 5 }

4) use this role:

\sqrt{ {x}^{2} }  = x

2 \sqrt{3 \times 5}

a car starts from rest and travels for 5.0s with a uniform acceleration of 1.5 m/s^2. what is the final velocity of the car? how
AfilCa [17]
V = u + at
u = 0 
v = 0 + 1.5*5
v = 7.5 m/s
final velocity is 7.5 m/s

s = ut + 0.5at^2
s = 0 + (0.5*1.5*5^2)
s = (0.5*1.5*25)
s = 18.75 m
total travel distance is 18.75 m.
