Answer:
19/24 pounds of grapes
Step-by-step explanation:
The LCD here is 24; both 8 and 12 divide evenly into 24.
Thus, the original problem involves adding:
9
-----
24
+ 10
------
24
and this sum comes to (9 + 10)/24, or 19/24.
She bought 19/24 pounds of grapes.
Answer:
X=-3, y=-4, z=-5
Step-by-step explanation:
X-4y+3z=-2......(1)
2x-y+4z=-22....(2)
3x-3y+4z=-17.....(3)
-2(1)+(2) and -3(1)+(3) we get:
7y-2z=-18....(4)
9y-5z=-11.....(5)
Now 5(4)-2(5) we get:
17y=-68 so
y=-4
Put y=-4 in (4) we have:
-28-2z=-18, then 2z=-10, so we have:
z=-5
Now put y=-4 and z=-5 in (1) we get:
x+16-15=-2, then
X=-3
Answer:
(4,3)
Step-by-step explanation:
y axis for away straight line down.
The nut lands first on gorund
<em><u>Solution:</u></em>
The squirrel climbs down the tree in 2 seconds
Given that,
A squirrel is 24 feet up in a tree and tosses a nut out of the tree with an initial velocity of 8 feet per second
<em><u>The nuts height, h, at time t seconds can be represented by the equation:</u></em>
time cannot be negative, so ignore t = -1
Thus the nut takes 1.5 seconds to reach ground
From given,
The squirrel climbs down the tree in 2 seconds
Therefore, the nut lands first on gorund
