Answer:11.5
Step-by-step explanation:
distance=6 2/5 + 2 3/4 + 2 1/3
d=(5x6+2)/5 + (4x2+3)/4 + (3x2+1)/3
d=32/5 + 11/4 + 7/3
d=(12x32+15x11+20x7) ➗ 60
d=(384+165+140) ➗ 60
d=689 ➗ 60
d=11.5
Answer:
Therefore, Company B is offering the lowest price/lb at $12.73/lb.
So, Company A's price / lb = ($32.50/2.5lbs) = $13.00/lb
Step-by-step explanation:
To determine price per lb, divide dollar amount by lbs.
- Company A sells 2 1/2lbs (2.5lbs) for $32.50
- Company B sells 2 3/4lbs (2.75lbs) for $35.00
And, Company B's price / lb = ($35.00/2.75lbs) = $12.73/lb
Answer: $33.00
Step-by-step explanation:
Given
Mr. Claussen needs 15 Pounds of ground beef
It is stated that 2 pounds of beef cost $4.40
Using unitary method
1 Pound cost ![\frac{4.4}{2}=\$2.2](https://tex.z-dn.net/?f=%5Cfrac%7B4.4%7D%7B2%7D%3D%5C%242.2)
For 15 pounds it is
![\Rightarrow 15\times 2.2=\$33](https://tex.z-dn.net/?f=%5CRightarrow%2015%5Ctimes%202.2%3D%5C%2433)
Thus, he has to spend $33 for 15 pound meat
Answer:
6(6x^2-4x-3)
Step-by-step explanation:
pull out the gcf which is 6 and it is complete because it is impossible to factor 6x^2-4x-3
In the
plane, we have
everywhere. So in the equation of the sphere, we have
![25=(x-2)^2+(y+10)^2+(-3)^2\implies(x-2)^2+(y+10)^2=16=4^2](https://tex.z-dn.net/?f=25%3D%28x-2%29%5E2%2B%28y%2B10%29%5E2%2B%28-3%29%5E2%5Cimplies%28x-2%29%5E2%2B%28y%2B10%29%5E2%3D16%3D4%5E2)
which is a circle centered at (2, -10, 0) of radius 4.
In the
plane, we have
, which gives
![25=(x-2)^2+10^2+(z-3)^2\implies(x-2)^2+(z-3)^2=-75](https://tex.z-dn.net/?f=25%3D%28x-2%29%5E2%2B10%5E2%2B%28z-3%29%5E2%5Cimplies%28x-2%29%5E2%2B%28z-3%29%5E2%3D-75)
But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the
plane,
, so
![25=(-2)^2+(y+10)^2+(z-3)^2\implies(y+10)^2+(z-3)^2=21=(\sqrt{21})^2](https://tex.z-dn.net/?f=25%3D%28-2%29%5E2%2B%28y%2B10%29%5E2%2B%28z-3%29%5E2%5Cimplies%28y%2B10%29%5E2%2B%28z-3%29%5E2%3D21%3D%28%5Csqrt%7B21%7D%29%5E2)
which is a circle centered at (0, -10, 3) of radius
