Use similar volume to calculate
which is the (ratio of edges)^3 = (ration of volume)
so just put the numbers in, let the volume of smaller pyramid be y.
(3/4)^3 = y/320
27/64 = y/320
y=135in3
65 people=20 minutes
20*3=60 minutes which is 1 hour
65*3=195 people per hour (This is the rate per hour)
195*6=1,170 people per six hours
Answer:
<h2>D) (12 × 8) + (12 × 5)</h2>
Step-by-step explanation:
The distributive property: <em>a(b + c) = ab + ac</em>
<em></em>
We have 12(8 + 5).
Use the distributive property:
12(8 + 5) = (12)(8) + (12)(5) = (12 × 8) + (12 × 5)
Answer:
Earned = 160 + 20d
Step-by-step explanation:
Seeing as Elmo works 20 hours per week at each job, that means he worked 20 hours at the $8 job and 20 hours at the $d job.
First find how much he earned from his $8/hr job.
(20)8 = 160
Elmo earned $160 at this $8/hr job.
Next, we know he earns $d/hr at his other job, and he works 20 hours at that job as well.
(20)d = 20d
Add the earnings from both jobs together.
160 + 20d = total earnings
