In 3 3/4 hours one day in January, it snowed 3 ft in Amarillo. How much snow fell per hour?

3 feet / 3.75 hours = 0.8 feet of snow per hour

Since you are trying to find how much it snowed per hour you would divide the amount of snow by the amount of hours so you would divide 3 by 3.75 to get 0.8 feet (8 inches) of snow each hour

Given right triangle DEF, what is the value of sin(E)? A. 3/5 B. 3/4 C. 4/5 D. 4/3

wariber [46]

Answer: OPTION A.

Step-by-step explanation:

First you must calculate the lenght of the side DF by applying the Pythagorean theorem, as following:

$DE=\sqrt{10^{2}-8^{2}}=6$

Now you can find sin(E) as you can see below:

$sin\alpha=opposite/hypotenuse$

Where:

$\alpha=E\\opposite=DF=6\\hypotenuse=EF=10$

Then:

$sin(E)=6/10$

$sin(E)=3/5$

562 ÷ Choose... = 14 R2

Zolol [24]

Answer:

7868

Step-by-step explanation:

⇒ This can be written algebraically (with a variable x) as:

562 ÷ x = 14

⇒ Convert the division as a fraction:

$\frac{562}{x}$ = 14

⇒ Multiply both sides by 562 to get rid of the fraction and to isolate the variable x:

562 · $\frac{562}{x}$ = 14 · 562

⇒ Simplify:

x = 7868

Answer: 7868

Hope this helps! :)

A submarine starts at sea level and travels to a position that is a little lower than −24 feet. Use the drop-down menus to compl

Black_prince [1.1K]

Answer:

The submarine's position means the distance it traveled is greater than 24 feet
A possible position of the submarine is -27 feet

Step-by-step explanation:

Distance is generally a positive number. (Displacement, or position may be negative, as in this case.) If the sub started at 0 feet and went lower than -24 feet, it traveled a distance of more than 24 feet (greater than 24 ft).

Of the numbers listed, the only one lower than -24 is -27.
