Answer:
$7.99 for 1/2 pounds cost less per pound
Step-by-step explanation:
we know that
The unit rate is equal to divide the total cost by the total weight
step 1
Find out the unit rate of the first package
$11.25 for 2/3 pounds
The unit rate is
step 2
Find out the unit rate of the first package
$7.99 for 1/2 pounds
The unit rate is
therefore
The second package cost less per pound
Answer:
849.24 cm²
Step-by-step explanation:
we know it is a cube so to find the surface area of each square you do
12x12=144 and there are 5 sides so 144x5=720
We know sides of the squares are 12 cm so half of that (6) would be the bottom of the triangle
Now using pythagorus you would do a²+b²=c²
15²+6²=c²
225+36=c²
√261=√c²
16.15=c this only half of one of the sides of the pyramid so you would times 16.15 by 8 to equal 129.24
now add 720+129.24=849.24 cm²
