Answer:
9 cm.
Step-by-step explanation:
Let x be the number of hours.
We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of , so the snow melted in x hours will be .
Since initially there was 10 cm of snow, so the depth of snow after x hours will be:
To find the depth of snow after 3 hours we will substitute in our expression.
Therefore, the depth of the snow on cherry street after 3 hours will be 9 cm.

Answer: 33
Step-by-step explanation:
We know that Jacob is 5 and 1/2 tall. He caused a 8 foot shadow, and we know that the flagpole causes a 48 foot shadow. 48/8 equal 6, meaning we need to multiply his height by that. 5 1/2 time 6 is 33
Answer:
525
Step-by-step explanation:
If you want exactly one ace, then your answer is correct. (525) is the number of 5-card hands in the deck, and you have 4 choices for which ace to include (hence, (41)), and 48 choose 4 choices for the other 4 cards (hence, (484)).
hope this helps!
Answer:
Step-by-step explanation:
<u>Pendulum</u>
The length of the pendulum is 0.4 m or 40 cm. When swinging, it reaches the top height of 4 cm from the bottom. The geometric construction of this situation is shown in the image below.
The right triangle is formed by the length of the pendulum (40 cm), its horizontal displacement, and the vertical height projected by the pendulum.
This last distance is calculated subtracting the total length of the pendulum and the vertical displacement reached in its higher position.
We need to calculate the angle θ, for which we'll use the cosine since we know the adjacent leg and the hypotenuse:
The angle is
