Answer:
6x²y(9 - 2y)
Step-by-step explanation:
Step 1: Factor out GCF
6(9x²y - 2x²y²)
Step 2: Factor out <em>x²</em>
6x²(9y - 2y²)
Step 3: Factor out <em>y</em>
6x²y(9 - 2y)
And we have our factored answer.
Answer:
the answer is a, unchecked growth
Here is your solution.. hope it helps
Answer:
The relative frequency of mammals in the survey is 30%.
Step-by-step explanation:
Relative frequency is the ratio of the occurrence of a singular event and the total number of outcome
Amphibians Insects Fish Reptiles Birds Mammals
12 30 9 25 22 42
Relative frequency = 
Total number of wildlife animals = 12+ 30 +9 +25+22+42 = 140
Now the relative frequency of mammals in the survey = 
the relative frequency of mammals in the survey =
= 0.3
Converting into percentage , we get
=
= 30 %
It can be done.
You must take a few steps to set it up, but then you are able to count 7 minutes. The setup makes you be able to time 2 minutes on the 5-minute sandglass and then you do another 5 minutes on the same sandglass.
Setup:
Start both sandglasses at the same time. When the 5-minute sandglass runs out, the 8 minute sandglass has 3 minutes of sand left. At this moment, start the 5 minute sandglass again.
When the 8-minute sandglass finishes the remaining 3 minutes, the 5-minute sandglass has 2 minutes left.
Actual timing of 7 minutes:
Let the 2 minutes pass, and immediately turn over the 5-minute sandglass to count an addition 5 minutes. The last 2 minutes of the 5-minute sandglass plus an additional 5 minutes of the 5-minute sandglass add to 7 minutes.
