2 3/4 divided by 1/4
is
2 3/4 multiplied by 4/1
which is (2+3/4)*4 = 2*4 + 3/4*4 = 8+3 =<em>11</em>
Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2
Answer: L=90-10t
0-90
1-80
2-70
3-60
Step-by-step explanation:
that should be right lol
because it decreases by ten a week so just count down by ten each week. Then, you can make the equation 90-10t and if you substitute each week for t it is true.
90-10(0)=90-0=90
90-10(1)=90-10=80
and so on...
Answer:
y = 36x
Step-by-step explanation:
Given that x and y vary directly then the equation relating the is
y = kx ← k is the constant of variation
To find k use the condition x = 
, y = 12, then
k = 
= 
= 12 × 3 = 36
y = 36x ← equation of variation
