Answer:

1. Wind is the horizontal movement of air. All wind is caused by the uneven heating of Earth's surface, which sets convection currents in motion, Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds.

2. Local winds blow between small low and high pressure systems. Local winds blow over a very limited area, while large scale winds blow over very unlimited area.

Anyone? Help please its my final test!!!

Pavlova-9 [17]

Answer:

yes ; 17.5 ft

Step-by-step explanation:

Triangle PRQ is isosceles

the base angle are equals

we know two legs, so we can find the tangent of angle x

tan = opposite/adjacent

tan = 7/16 = 0.4375

the angle x measure 23.6 degrees circa (we can calculate this with the button tan -1 on the calculator)

the roof is safe

B we can use the Phytagorean theorem to solve this

PR = √16^2 + 7^2 = √256 + 49 = 17,46... = 17.5 ft

A circle has an area of approximately 615 square millimeters. What is the diameter of the circle

noname [10]

Answer:

When using the given information, the diameter of the circle is going to be 28 mL.

Step-by-step explanation:

First, we need to know the formula for finding the area of a circle.

$Area=r^2\pi$

Now, we need to rearrange the formula so we can find the radius.

$Radius=\sqrt{\frac{A}{\pi} }$

Next, we plug in the given area into the equation.

$Radius=\sqrt{\frac{615}{\pi}}$

$Radius=\sqrt{196}$

$Radius=14$

Now that we have the radius, we can find the diameter. The radius is half the length of the diameter. So, in order to find the diameter, we have to multiply the radius by 2.

$14 * 2=28$
