The average winter snowfall in City A is 105 cm. City B usually gets 2.8 m of snow each winter. Compare the yearly snowfall in t
Inessa [10]
We see that city A gets 105 cm of snow while city B gets 2.8 m. The first thing we do is make both measurements equal to each other. This can be done by either converting city A's 105 centimeters to meters or city B's meters to centimeters. But the question specifically calls for both, so we get both measurements.

City A: 105 centimeters OR 1.05 meters
City B: 280 centimeters OR 2.8 meters

Now that we know the measurements, let's look at the first problem. (A) asks for the difference in one year in meters. The difference of course means subtraction. Now it's here where I personally am confused on what it asking for in terms of which city is it asking for us to subtract from, but using an educated guess, I'll say we're subtracting from city B because if we were to subtract from city A, we'd have a negative, and you can't have a negative amount of snow, only 0 snow.

So once again, for question (A), we subtract 1.05 from 2.8 (2.80 - 1.05) and we get 1.75 meters of snow.

Question (B) asks for the difference during two years in centimeters, so we multiply both measurements by 2 and use the centimeter measurements. (105 x 2 = 210) (280 x 2 = 560) Subtract 560 from 210 (560 - 210) and we get 350 centimeters.

So your answers are: (A) 1.75 meters (B) 350 centimeters

I hope this helps!

Find the length of the altitude to the hypotenuse. round the answer to the nearest tenth, if needed.
Amiraneli [1.4K]

Answer : The correct option is, (B) 56.8

Step-by-step explanation :

Right Triangle Altitude Theorem:

The measure of altitude drawn from the vertex of the right angle of a right angled triangle to its hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse.

We are drawing a line from vertex to hypotenuse side.

As per theorem:

\frac{BD}{AB}=\frac{CB}{AC}

\frac{BD}{60}=\frac{175}{185}

BD=\frac{175\times 60}{185}

BD=56.8

Therefore, the length of the altitude to the hypotenuse is 56.8

(I meant to make this category be science but I accidentally clicked math)
Mekhanik [1.2K]

Answer: Physical weathering is when the physical structure of something is broken down..fast moving water is an example of this because it physically changes the structure of rocks over time. Chemical weathering is the erosion of materials from chemical reactions. Chemical weathering occurs more on a molecular level. An example of chemical weathering is when the minerals in rocks are dissolved by water, which creates a new compound

Hope this makes sense and helps!
