Answer:

Change in temperature = -9 degrees

Step-by-step explanation:

Given

Start Temperature = 10 deg

Change = 3 deg/hr

Time= 3hr

Required

Change in temperature;

First, the total change in 3 hours has to be solved for. This is done as follows:

Total Change = Change* Time

Total Change = 3 deg/hr * 3 hr

Total Change = 9 deg

From the question, we understand that the temperature dropped.

So,  we can conclude that the temperature changed by -9 degrees;

This means that at the end of the third hour is temperature is 1 degrees

olga_2 [115]

Answer: Badwater is 282 feet below the sea level.

Step-by-step explanation:

Given: Death Valley headquarters in California is 190 feet below sea level. Badwater, America's lowest point, is 92 feet lower than Death Valley headquarters.

To find the depth of Badwater we need to add depth of Death Valley headquarters from sea level to the depth of Badwater from Death valley headquarters.

i.e. The Depth of Badwater from sea-level = 190 feet +92 feet

= 282 feet

Hence, Badwater is 282 feet below the sea level.

1. Determine the variables in the figure below.<br> 20<br> 50
Marina CMI [18]

Answer:

r=8

t=4√29

Step-by-step explanation:

By the altitude leg theorem:

{20}^{2}  = 50r

This implies that:

r =  \frac{20 \times 20}{50}

We simplify to obtain:

r = 4 \times 2 = 8

By the Pythagoras theorem:

{t}^{2}  =  {20}^{2}  +  {8}^{2}

{t}^{2}  = 400 + 64

{t}^{2}  = 464

t =  \sqrt{464}

t = 4 \sqrt{29}
