Answer:
Minimum value: 6 inches,
Maximum value: 8 inches.
Step-by-step explanation:
To find the minimum length of s, we need to use the minimum volume of the shipping box in the equation, so:
s_minimum = ^3√(2*108) = ^3√216 = 6 inches
The maximum value of the volume will give us the maximum value of the length:
s_maximum = ^3√(2*256) = ^3√512 = 8 inches
So the minimum value of the length is 6 inches and the maximum value is 8 inches.
First, let's multiply the first equation by two on the both sides:
<span>8x + 7y = 39 /2
</span>⇒ 16x + 14y = 78
Now, the system is:
<span>16x + 14y = 78
</span><span>4x – 14y = –68
</span>
After adding this up in the column:
(16x + 4x) + (14y - 14y) = 78 - 68
20x = 10
⇒ x = 10/20 = 1/2
y can be calculated by replacin the x:
<span>8x + 7y = 39
</span>⇒ 8 · 1/2 + 7y = 39
4 + 7y = 39
7y = 39 - 4
7y = 35
⇒ y = 35 ÷ 7 = 5
Answer:
P = 2(2y+3)
P = 30
Step-by-step explanation:
P = 2 (L+W) or P = L + L + W + W
P = 2 (2y+3)
P = 4y+6
Plug in 6 for y.
P = 24+6
P = 30
Answer:
10 posters are .12 and 100 are 1.2 inches 1000 posters are 12 inches.
Step-by-step explanation:
.012×10=.12 in
For every 0 in the ten move the decimal back 1.
.012×100=1.2 in
.012×1000=12 in
