Answer:
58.75 degreeF
Step-by-step explanation:
The initial temperature of the Soda = 40degreeF
The temperature outside is steady at 99 degreeF
The temperature of the soda became 50 degreeF after 8 minutes
In 8 minutes, the Soda gained
(50 - 40)degreeF
= 10 degreeF
If the soda gains 10 degreeF in 8 minutes, in 1 minute, it will gain 10/8degreeF
Therefore in 7 minutes, the soda will gain (10/8)*7
= 70/8
= 8.75 degreeF
The expected temperature of soda after an additional 7 minutes = 50 + 8.75
= 58.75degreeF
The sounds of music are related to trigonometric functions because trigonometry is used in measuring the level of the pitch of a sound wave or musical note.
<h3>How is trigonometry used in sound?</h3>
It should be noted trigonometry is important for measuring pitch level. The notes are measured in Hertz.
A sound wave's amplitude relates to the change in the pressure that's caused by the wave measured at a specific location.
The sound is perceived as louder when the amplitude increases.
Pieces of music often have repetitive choruses or bars, similar to patterns. In mathematics, we look for patterns to interpret and predict the unknown. Music uses the same techniques. If you look at a piece of music, artists look at the notes they see to find the rare (high or low) and uncommon notes.
In this way, the notes are related. Relationships are important in mathematics and create an interesting link between music and mathematics.

Answer:
35
Step-by-step explanation:
The formula for area is length x width, so we multiply 10 x 3.5, which equals 35.
Hope this helps :)
When you change the radius (multiply by k), a 1D size, the circumference is multiplied by k (1D), while the area is multiplied by
(2D). I hope this helps on this problem and others.
Answer:
87.4877 meters
Step-by-step explanation:
First we can make two right triangles as shown on the images below. So first let's calculate the height of the top triangle:
Where x = 30m, , and r is the hypotenuse which is to be determined and so:
Now we will input our r value into our y equation and so:
So the height of the top triangle is 31.0659 meters.
Similarly let's calculate the height of the bottom triangle:
Now we'll plug it into our y equation:
Therefore by adding the height of both triangles we obtain:
31.0659m + 56.4218m = 87.4877m
