Answer:

27.4 yards

Explanation:

The diagonal of a rectangle, one of it's length and one of it's width will form a right angle triangle

Let

Width = x

Length = 2x

Diagonal = 80 yards

c^2 = a^2 + b^2

Where

c= diagonal

a= length

b= width

c^2 = a^2 + b^2

80^2 = (2x)^2 + (x)^2

80^2 = 2x * 2x + x^2

80^2 = 4x^2 + x^2

6,400= 5x^2

Divide both sides by 5

x^2= 6400 / 5

= 1280

x^2 = 1,280

Find the square root of both sides

√x^2 = √1,280

x= 35.8

How many​ yards, to the nearest tenth of a​ yard, does a person save by walking diagonally across the land instead of walking its length and its​ width?

Yards saved= (Length + width) - diagonal

= (2x+x) - 80

= {2(35.8) + 35.8} - 80

= (71.6 + 35.8) - 80

= 107.4 - 80

= 27.4

Yards saved = 27.4 yards

A researcher wishes to define the receptive field for a particular neuron in the visual cortex. To do this, the researcher will
Katarina [22]

Answer:

an area within the visual field wherein the cell will fire if the target appears.

Explanation:

In order to accomplish this, the researcher will need to specify an area within the visual field wherein the cell will fire if the target appears. This is because there are about 100 billion neurons in the human brain and each of them fires at a speed of about 200 times per second, thus making it impossible to define the receptive field of a particular neuron without highlighting a specific area of that neuron and visualizing that specific neuron.

Due to the​ Gramm-Leach-Bliley Act of 1999
Anuta_ua [19.1K]

Answer:

C. the US government allowed commercial banks to own stock and sell insurance policies.

Explanation:

The Gramm-Leach-Bliley Act (GLBA) of 1999 basically repealed or revoked or cancelled the Glass-Steagall Act of 1933. The Glass-Steagall Act of 1933 forbids the commercial banks to own stock and sell insurance policies. So basically by cancelling that Glass-Steagall Act of 1933, the GLBA of 1999 allowed the commercial banks to own stock and sell insurance policies.
