Answer:
84
Step-by-step explanation:
let a be the 1's digit and b the 10's digit, then
a = 2b ← twice the 10's digit, thus
sum = 2b + b = 12, that is
3b = 12 ( divide both sides by 3 )
b = 4
and a = 2b = 2 × 4 = 8
The 2 digit number is 84
Answer:
1)1920 in2 (2)120 in3
Step-by-step explanation:
<span>Remember::
a) velocity is the first derivative of the position vector
b) acceleration is the second derivative of the position vector or, what is the same, the first derivative of the velocity vector.
Using that, you get:
1) given: r(t)=(2+t^2, 3t)
2) v(t) = d r(t) / dt = (2t, 3)
3) a(t) = d (v(t)) / dt = (2,0)
Answer: option </span><span>b) v(t)=(2t, 3) ; a(t)=(2, 0)</span><span>

Label your graph the horizontal line is “X” and the vertical line is Y”. the origin is always (0.0) which is where the two lines meat dead center of the graph. From the origin go to the left counting in negatives... 0,-1,-2,-3.... etc. do the same thing going towards the right but in positives, then go up from the origin counting in positives and then down from the origin in negatives like you did going left. OKAY now if a coordinate is (-3,6), -3 is your “X” and 6 is your “Y” so you would go left negative 3 on the X line (horizontal line) and once you get to negative 3 you go UP 6. There is your first coordinate plotted on your graph
A candy store sells 8 pound bags of mixed almonds and cashews. If c pounds of cashews are in a bag,...
c=1 was already given as described. The store sells pound bags.
The rest of the description and question seem not to match. Maybe each bag contains 8 pounds of the two nuts. Eight pounds and some of this is of cashews. Now, c is how many pounds of cashews in one bag.
-
p=2.59%2Ac%2B1.72%288-c%29
You want to know the quantity of cashews if p=18.11 dollars per bag.
2.59c%2B1.72%2A8-1.72c=p
2.59c-1.72c=p-1.72%2A8
%282.59-1.72%29c=p-1.72%2A8
0.87c=p-13.76
