Answer:
The Algebraic expression representing amount spent on 'p'pencil and 'm' pens is
.
Step-by-step explanation:
Given:
Amount spent on each pencil = $0.50
Amount spent on each pen = $0.25
Let the Number of pencils be 'p'.
Let the number of pens be 'm'.
We need to find the Algebraic expression to find the amount spent on pencils and pens
Solution:
Now we can say that;
The total amount spent is equal to sum of Amount spent on each pencil multiplied by the Number of pencils and Amount spent on each pen multiplied by the Number of pens.
framing in equation form we get;
The total amount spent = ![0.5p+0.25m](https://tex.z-dn.net/?f=0.5p%2B0.25m)
Hence The Algebraic expression representing amount spent on 'p'pencil and 'm' pens is
.
Answer:
294.375 or 294.38
Step-by-step explanation:
Volume of a circle:
πr³
If the diameter of a circle is 10, the radius is 5 .
5³ = 125
125 x 3.14 = 392.5
392.5 x
= 294.375 or 294.38
Answer:
Diamonds is incorrect, because, the volume of the softball is 8 times the volume of the golf ball
Step-by-step explanation:
we know that
The volume of a sphere is equal to
![V=\frac{4}{3}\pi r^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
where
r is the radius
step 1
Find the volume of the golf ball
we have
![r=2.1\ cm\\pi =3.14](https://tex.z-dn.net/?f=r%3D2.1%5C%20cm%5C%5Cpi%20%3D3.14)
substitute
![V=\frac{4}{3}(3.14)(2.1)^{3}=38.77\ cm^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%283.14%29%282.1%29%5E%7B3%7D%3D38.77%5C%20cm%5E3)
step 2
Find the volume of the the softball
we have
![r=4.2\ cm\\pi =3.14](https://tex.z-dn.net/?f=r%3D4.2%5C%20cm%5C%5Cpi%20%3D3.14)
substitute
![V=\frac{4}{3}(3.14)(4.2)^{3}=310.18\ cm^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%283.14%29%284.2%29%5E%7B3%7D%3D310.18%5C%20cm%5E3)
step 3
Find the ratio of volumes
Divide the volume of the softball by the volume of the golf ball
![\frac{310.18}{38.77}=8](https://tex.z-dn.net/?f=%5Cfrac%7B310.18%7D%7B38.77%7D%3D8)
That means
Diamonds is incorrect, because, the volume of the softball is 8 times the volume of the golf ball
