Which shape has the same volume as the given rectangular prism?<br><br><br><br><br><br> Thank you!
jarptica [38.1K]
The correct option is (a) i.e. cylinder.

This is because:
Volume of a Rectangular Prism = (Area of base * Height)
= 50 *5 = 250 cm^3

And volume of cylinder = πr^2h = 50*5 = 250cm^3

Thus, the cylinder has the same volume as the rectangular prism

What expression represents the sum of 8 and twice a number
jolli1 [7]
Idk if you have any choices or not but it should look like 8 + 2x
How to get the answer: sum means addition, and twice a number is 2 times it. We don't know the number so we'll use x. Two times a number is 2x
And since we are adding we will put an addition sign
8 + 2x

A trumpet has a length of 140cm. The first valve lowers the root note by two semitones (f1/f0 = 2-2/12) and the second valve low
Alexxandr [17]

Answer:

a.  17.145cm

b. 8.325cm

c. 0.846

d. 2.896

Step-by-step explanation:

It is known that frequency is inversely proportional to length.

Case 1: The player presses only the first valve.

f₁/fo = 2^{-2/12} = lo/l₁

given that lo= 140cm.

l₁ = 2^{2/12}lo = 157.145

change in length:

l₁ - lo = 157.145 - 140 = 17.145cm

Case 2: The player presses only the second valve.

f₂/fo = 2^{-1/12} = lo/l₂

l₂ = 2^{1/12}lo = 148.325cm

l₂  - lo= 148.325-140 = 8.325cm

Case 3: The player presses both the first and second valve.

Change in length is the sum of change in length when they are individually pressed.

l₃ - lo = 17.145+8.325 = 25.47cm

l₃ = 25.47cm+lo = 165.47cm

f₃/fo  = 2^{-n/12} = lo/l₃

f₃/fo = 2^{-n/12} = 140/{165.47 = 0.846

2^{-n/12} = 0.846\Rightarrow n/12 = -log(0.846)/log(2) = 0.2413

n = 0.2413*12 = 2.896
