Answer:
$144
Step-by-step explanation:
Volume of the pyramid = 1/3BH
Base area B = 1/2 * 6 * 4
Base area B = 12 ft²
Height H = 4ft
Volume of the pyramid = 12 * 4
Volume of the pyramid = 48ft³
SInce 1 ft³ = $3
48ft³ = x
Cross multiply
x = 3 * 48
x = 144
Hence the cost of the sign is $144
Answer:
8.41
Step-by-step explanation:
i think
x = # of ham sandwiches
14-x = # of turkey sandwiches ( as Lexi made 14 sandwiches)
as the question said that the number of ha sandwiches are 4 less than twice number of turkey sandwiches,
x = 2 * (14-x) - 4 = 24 - 2x
3x=24
x = 8
the number of ham sandwiches is 8, and the number of turkey sandwiches is 14-8=6
To solve the inequality 3/10 is greater than or equal to k - 3/5, we must first set it up. Since 3/10 is greater than or equal to something, we will have a greater than or equal to symbol, with the 'mouth' pointing towards 3/10. Setting this up we get:
3/10 ≥ k - 3/5
Now we want to get k by itself on one side. We can do this by adding 3/5 to each side.
3/10 + 3/5 ≥ k
Simplify
9/10 ≥ k
