Answer: V=9.4 cm^3
Step-by-step explanation:
![V=\pi r^2h\\V=\pi (1)^2(3)\\V=9.4cm^3](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h%5C%5CV%3D%5Cpi%20%281%29%5E2%283%29%5C%5CV%3D9.4cm%5E3)
I think it is 6 (Would be 6/9)
4/5 - ?/9 = 6/45
Make the denominators the same
4/5 (9/9) = 36/45
?/9 (5/5) = ?/45
To get the number, you take 6 from 36 to get 30. And to check, 36-30=6.
Now the fraction is 30/45 and you divide both numbers by 5 to get back to the previous number which would be 45/5 = 9 and 30/5 = 6 which gets you 6/9
Answer:
Step-by-step explanation:
sqrt(2+x) <u>></u> 6-2x
taking square on both sides
2+x <u>></u> 36-24x+4x^2
0 <u>></u> 34-25x+4x^2
0 <u>></u> (2x)2-2(2x)(25/4)+(25/4)^2 -(25/4)^2 +36 (by completing square)
49/16 <u>></u> (2x-25/4)^2
taking square root
7/4 <u>></u> 2x-25/4 , -7/4 <u><</u> 2x-25/4
8 <u>></u> 2x , 9/2 <u><</u> 2x
4 <u>></u> x , 9/4 <u><</u> x
Number of pins produced per hour is 1000
value of each pin is $8.37
total value of pins produced= 1000×$8.37
=$8370
Answer:
200
Step-by-step explanation:
12% is equal to 12/100
I would set up something like
12/100= 24/x
to get from 12 to 24, you have to multiply by 2.
do the same for 100 so 100 x 2= 200
