Answer:
B 12
Step-by-step explanation:
- manuel ate 1/3X
- His brother ate 1/4X
- leftover is 5
- total is X
manuel+brother+leftover=X
x/3+x/4+5=x
7x+60/12=x
7x+60=12x
60=12x-7x
60=5x
x=60/5
x= 12
Since I don't see attachment, I guess the solution will be as follows:
1 & 3/4 , since 1 = 4/4, then it could be rewritten :
4/4 & 3/4, hence between these 2 fraction there is 2/4 or 1/2.
Step-by-step explanation:
Let's say R is the initial radius of the sphere, and r is the radius at time t.
The volume of the sphere at time t is:
V = 4/3 π r³
Taking derivative with respect to radius:
dV/dr = 4π r²
This is a maximum when r is a maximum, which is when r = R.
(dV/dr)max = 4π R²
This is 4 times the sphere's initial great circle area, but not the great circle circumference. The problem statement contains an error.
Which statements are true about the ordered pair <span>(−1, 5)</span> and the system of equations?
<span>{<span><span>x+y=4 </span><span>x−y=−6</span></span></span>
Select each correct answer.
<span>The ordered pair <span>(−1, 5)</span> is a solution to the first equation because it makes the first equation true.The ordered pair <span>(−1, 5)</span> is a solution to the second equation because it makes the second equation true.The ordered pair <span>(−1, 5)</span> is not a solution to the system because it makes at least one of the equations false.The ordered pair <span>(−1, 5)</span> is a solution to the system because it makes both </span>
