6. El club de Matemáticas se fijó la meta de recoger 50 lbs de latas de aluminio para reciclar. Llevaron tres bolsas llenas al centro de reciclaje para pesarlas. Las bolsas pesaban
6.3 lbs, 8.1 lbs y 7.45 lbs respectivamente.
¿Cuántas libras de aluminio le falta por recoger para alcanzar la meta?
(1 Punto)
O A. 14.40 lbs
O B. 15.55 lbs
O C. 21.85 lbs
O D. 28.15 lbs

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
