Answer:
3 packages of plates, 2 packages of cups
Step-by-step explanation:
Find the multiples of 8 and 12, the lowest one they have in common will help with your answer.
8 : 8 16 24 32 40 48 56
12 : 12 24 36 48
The number that they both have (least) in common is 24.
For 8, it is the 3rd multiple and for 12 it would be the second
Answer:
w = 160, L = 50
Step-by-step explanation:
Length = 50 feet
Width = 160 feet
First Find the Length
w = l + 110
P=2w+2l
420=2w+2l
420=2(l+110)+2l
420=2l+220+2l
4l=200
l=50
Finding the Width
w=(50)+110
w=160
Answer:
the ball reaches a height of 64 feet after 2 sec.
The ball is in the air 4 sec.
Step-by-step explanation:
The ball is following the path of a parabola. The maximum height is at the vertex of the parabola.
Let (h, k) be the vertex. h will be the time it takes to reach the maximum height, and k will be that height.
y =
h = -b/2a = 64/(-2)(-16) = 64/32 = 2
k = -16(2)^2 + 64(2)
-16(4) + 128
- 64 + 128 = 64
V: (2, 64)
So the ball reaches a height of 64 feet after 2 sec.
Let = 0 (0 is the height when the balls hits the ground)
-16t(t - 4) = 0
t = 0 or t = 4
The ball is in the air 4 sec.
Step-by-step explanation:
180 degrees ok.
height of the goal is 90
Answer:
x ≈ 10.9
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = = ( multiply both sides by x )
x × sin40° = 7 ( divide both sides by sin40° )
x = ≈ 10.9 ( to the nearest tenth )
