Oh ok!
How many tens are in 100? =10
so, 10 * 5 = 50
Now, 50 + 4 = 54!
Hope so now i get it correct!
7 stamps* ($2.20/ 5 stamps)= $3.08.
(Note that the unit cancels out so you get the answer)
The final answer is $3.08~
Tomato juice 237.5 / 5.5 = 45 mg
Grape juice 258 / 3 = 86 mg
Answer: {-1, 1}
Explanation: If you plug in either 1 or -1 into the equation, it will satisfy the equation f(x) = 8.
The correct question is
<span>What is the equation in standard form of an ellipse centered at the origin and vertex (4,0) and focus (1,0)
</span>
we know that
<span>Standard form of equation for an ellipse with horizontal major axis is
(x-h)</span>²/a²+(y-k)²/b²=1
the center is the origin
so
(h,k) is (0,0)<span>length of horizontal major axis------> 8=2a-----> a=4
a</span>²=16
c=1 (distance from center to focal point)
c²=1
b²=a²-c²-----> b²=16-1----> b²=15
the equation is
(x)²/16+(y)²/15=1
the answer is
(x)²/16+(y)²/15=1
